Florida’s Largest Electric Company FPL Is Against Solar Power

solar power and the grid
"Instead of fighting climate change, some companies are trying to shut down rooftop solar energy. This is exactly what Florida Power & Light does because they don't want their business model threatened by new technologies that might end up reducing electricity demand in America's oldest markets- where most power plants operate today"

Rooftop solar power generation in Florida is an emerging industry that has the potential to decrease electric company profits. The FPL (Florida Power & Light) which lobby state lawmakers with records obtained by Miami Herald and Floodlight for legislation they asked them hand-deliver, shows how much this new form of energy backbone could hurt their business model currently based on selling fuel overheads like coal or natural gas plants do today.

In 2020, Florida Power & Light had a close ally in state Sen. Jennifer Bradley who sponsored their top-priority bill to make it more difficult for homeowners and businesses across the country who have installed rooftop solar panels – preventing them from offsetting costs by selling excess power back onto FPL’s grid at full retail price through a process known as net metering.

In November, the Florida Senate drafted a bill and sent it to DLG Bradley who then gave it back for review. The lobbyist representing FPL Drafted this legislation while her political advisory group received $10K from them after they saw how well-written our language was in order keep up with what’s going on at every level of government here! In fact just last month when State Rep Lawrence McClure introduced his version without any changes.

In Florida, only about 1% of the state’s more than 8 million customers sell excess energy back to utilities which equates to roughly 90,000 not including the thousands of people waiting in line to get set up with solar. However, this has driven significant rooftop solar expansion in recent years and Florida Power and Light is pushing for legislation that could seriously curtail these gains with their biggest utility having 5.5 million clients (65%), Duke Energy has 2 million, followed by TECO at 800k and many other smaller sized utility companies.

The fight against net metering is just another example of how utilities try to maintain their monopoly grip on electricity markets. They claim that this bill will devastate the business, but Solar Energy Industries Association director Will Giese says it doesn’t have much impact because people can still choose which type energy works best for them without any change or harm done under current rules — so long as they’re happy with whatever option their provider offers!

The Florida Public Service Commission has been receiving proposals from power companies on how they expect rooftop solar will affect their bottom line. One company, FPL (a utility) is arguing that because of this new technology called “distributed renewable energy” profits could be threatened by $700 million between 2019 and 2025 – which would mean less money for them; however scientists say with climate change we need these cleaner sources of electricity!

Florida Power and Light representative Chris McGrath said the organization doesn’t go against net metering however needs to see the ongoing regulation reexamined. He contended that clients with roof sun oriented are being sponsored by different clients who keep on purchasing power and pay to keep up with the power lattice.

“We basically accept roof sun oriented clients ought to pay the full expense of this venture,” McGrath said.

A long, political fight

The bill is only one front in a very long term fight against the arrangement. For quite a long time, Florida Power and Light has been perhaps the biggest supporter of regulative Florida political missions. It moved a bombed voting form correction in 2016 that would have permitted controllers to force charges and boundaries to roof sunlight based establishment. Florida Power and Light has additionally put millions into bunches with untraceable, mysterious contributors that sent off assaults on state and nearby lawmakers.

As indicated by detailing by the Orlando Sentinel, Florida Power and Light chiefs have been attached to a progression of ‘dull cash’ charities, one of which figures unmistakably in the Miami-Dade express lawyer’s examination concerning an outrage including a “phantom” Senate up-and-comer. Under the plan, an applicant with no political foundation was on the polling form as a no-party choice with an end goal to befuddle electors and weaken support for the Democrat in the race, assisting Republicans with keeping up with their greater part in the state Senate.

Florida Power and Light CEO Eric Silagy was straightforwardly engaged with directing assets to dim cash bunches drove by the specialists who controlled Grow United, the association used to advance the apparition up-and-comers, as indicated by archives got by the Sentinel. Holley, the Florida Power and Light lobbyist who conveyed the net metering language to the Senate, attempted to advance Republican Senate up-and-comers in the nearby races. Florida Power and Light denied any bad behavior connected with political missions.

“Any report or idea that we had association in, monetarily upheld or guided others to help any ‘apparition’ competitors during the 2020 political decision cycle is evidently bogus, and we have tracked down definitely no proof of any lawful bad behavior by FPL or its workers,” McGrath, the Florida Power and Light representative said because of inquiries for this story. Records got by the Sentinel likewise show cross-over between Grow United and past missions to upgrade net metering.

One individual partnered with Grow United is Abbie MacIver, who previously worked for Energy Fairness, a gathering that urges policymakers to consider the “cost of energy decisions, as well as their advantages.” Last year, McClure sent a letter to state controllers at the Florida Public Service Commission referring to the outcome and asking it to refresh its net-metering rule.

The commission held a studio, which drew 16,000 messages from sun oriented advocates asking it to let the net metering program be. Officials said it was the most elevated reaction rate they had gotten on any issue and inferred that no prompt changes to net metering should have been made.
“What individuals may not understand is that popular assessment is especially in support of ourselves,” said Bryan Jacob of the Southern Alliance for Clean Energy. “They have the campaigning power, and we have individuals power.”

How the bill came to exist from Florida Power and Light

Bradley, who got Florida Power and Light’s draft bill, is an initial term congressperson who is near Senate administration and seats the Community Affairs Committee and the Subcommittee on Congressional Reapportionment. Bradley is hitched to previous state Sen. Burglarize Bradley, a compelling legislator who was top of the Senate spending plan board of trustees.

Florida state Sen. Jennifer Bradley spoke during a regulative meeting, Thursday, April 29, 2021, at the Capitol in Tallahassee.
Bradley said the bill language arose after a gathering she had with Holley and different individuals from the utility business.

“I checked the language out. It depended on our conversation, and it was one that I could uphold as a beginning stage,” she reviewed.

Messages show that Bradley’s staff circled back to Florida Power and Light after that conversation. On Oct. 8, Bradley’s regulative assistant Katie Heffley messaged Holley with the title: “Net Metering Bill.”
“Good evening, Hope you’re getting along nicely,” she said. “I simply needed to check in and check whether you had any subsequent data or language concerning the net metering charge you talked about with Senator Bradley.”

Holley answered eight minutes after the fact: “I do. Might I at any point carry it to you all sometime in the afternoon?” he composed. Heffley proposed that he would be able “email it today or we will be at the Capitol one week from now.”

Holley declined to give an electronic rendition and proposed to “drop it off” face to face the next week. After ten days, Heffley composed Holley once more. “I simply need to connect and check whether I could get an electronic duplicate of the net metering bill so I can place it into drafting.”

After two days, Florida Division of Elections records show, Florida Power and Light’s parent organization, NextEra Energy, gave $10,000 to Bradley’s political council, Women Building the Future.

McClure’s political advisory group, Conservative Florida, got no utility cash during this time except for on Nov. 4 got a $10,000 commitment from Associated Industries of Florida’s political board of trustees, Voice for Florida business, which advances Florida Power and Light’s plan and whose experts have additionally chipped away at the dim cash crusades, as per the Orlando Sentinel detailing.

NextEra Energy said its political board didn’t make its commitment to Bradley’s mission “with an assumption for favor.”

These email records were given to the Times/Herald and Floodlight by the Energy and Policy Institute, a guard dog association that attempts to counter deception about sustainable power.

Most states provide net metering

Florida is one of 47 states that allows individuals and organizations to produce energy and to sale it back at a set rate. In any case, those strategies are experiencing harsh criticism as electric companies are against solar and are becoming progressively worried about how homeowners going solar can cut their profits. 

In California, controllers intend to increment expenses on roof sun oriented clients. Indeed, even a few natural promoters say the change is fair and important due to the quick pace of housetop sun based advancement in that state.

Housetop sun based, while basic to battling environmental change, is a danger to the customary utility plan of action.

Power organizations like Florida Power and Light bring in cash off of the things they assemble: basically huge power plants and the electrical cables that carry that energy to clients. They don’t bring in cash off of the sun oriented power produced from housetops.

Under Florida’s ongoing plan, homes and organizations that produce under 2 megawatts of sun oriented power can offer the abundance back to their utility in return for a bill credit of 11 pennies for each kWh. Florida Power and Light contends that game plan is uncalled for to clients who don’t produce their own power yet keep on paying for the expenses of keeping up with the network that roof sun oriented clients likewise use.

Housetop sun powered in Florida extended gradually until 2018 when the Florida Public Service Commission permitted power clients to rent nearby planet groups with almost no forthright expenses. That choice slung the development of limited scope sun based limit in the state. It developed by 57% in 2020, as per the U.S. Energy Information Administration.

Florida Power and Light says the expense of sponsoring its 24,000 net-metering clients was $30 million of every 2020 (about $1,250 per client).

The sun oriented industry dissents, highlighting research that shows roof sunlight based entrance is low enough in many states that “the impacts of disseminated sun powered on retail power costs will probably stay insignificant for years to come.”

However, utility specialists have vouched for the Florida Public Service Commission that roof sun oriented in the state could develop at a pace of 39% every year until 2025 assuming Florida’s ongoing net metering framework is left set up.

That development has the utilities, and lawmakers, stressed.

“Because of the ongoing framework, my constituents are being compelled to sponsor the choices of neighbors in different areas who are in a situation to have the option to put these costly frameworks on their homes,” Bradley said.

What the bill would do

Under Bradley’s bill, net-metering clients whose sunlight powered chargers convey energy back to the utility framework would never again get credits in view of the retail cost of energy, yet rather get credits in light of a lower discount cost. That cost depends on the “kept away from cost” that the utility would have brought about if it somehow managed to introduce a tantamount framework.

Draft legislation [Public records from the Florida Senate]

Draft regulation

In order to help minimize electricity imports, the new South Carolina law will allow utilities to charge rooftop solar customers more. The plan also includes expenses such as office charges and least regularly scheduled installments that are unique for these types of clients who use roof sun power before 2023; they would be grandfathered in with their past rates forever!

Florida currently has the second-biggest sunlight based labor force in the nation — around 11,000 direct positions and 31,000 aberrant ones, as indicated by the Solar Energy Industries Association. It positions third among states for introduced sunlight based limit, albeit quite a bit of that is huge scope, utility-possessed sun oriented.

Justin Vandenbroeck, the leader of the Florida Solar Energy Industries Association who likewise claims an Orlando-based sun powered establishment organization, said the sun oriented industry comprises for the most part of autonomously possessed private ventures. “Assuming that this bill passes for what it’s worth, it can possibly send Florida back to 2013, as though the advances of the most recent 10 years didn’t occur,” Vandenbroeck said.

McClure states the bill “isn’t prepared.”

“From the get-go in this bill’s ride, I think it has a genuine opportunity to settle out such that most gatherings are not vexed,” he said. He added that the net metering regulation has not been refreshed in 13 years and presently is an ideal opportunity to talk about it.

“We really want to have the discussion,” he said. “I’m not apprehensive in the event that the end is it’s not an opportunity. I feel housetop solar is advantageous to the climate, and Floridians. I’m worried that it will bring about tremendous expenses here, yet I likewise don’t have any desire to annihilate the roof sun powered industry in Florida.”

Katie Chiles Ottenweller, Southeast chief for Vote Solar, an Atlanta-based support association, is hopeful yet watchful given Florida Power and Light’s clout in the Florida Legislature and its job in drafting the bill.

“Organizations don’t pass regulation. Lawmakers pass regulation,” she said. “I’m confident this is an ice breaker be that as it may, simultaneously, it’s truly difficult to have a discussion when you have a firearm to your head. The bill as it is composed will demolish this industry.”

Where should we send?

Enphase Energy

An American NASDAQ-listed energy technology company headquartered in Fremont, California. Enphase designs and manufactures software-driven home energy solutions that span solar generation, home energy storage and web-based monitoring and control. Enphase has shipped about thirty million solar microinverters, primarily into the residential and commercial markets in North America. Microinverters convert the direct current power from the solar panel (DC) directly into grid-compatible alternating current (AC) for use or export. Enphase was the first company to successfully commercialize the microinverter on a wide scale, and remains the market leader in their production.


Enphase Energy pioneered the concept of a microinverter. The basic idea behind a microinverter is to convert, manage and monitor energy per panel, rather than the entire array of panels. This reduces the size of the inverter that can be placed on the back of the panel, producing an “AC panel”. Such a system can be connected directly to the grid, or to each other to produce larger arrays. This contrasts with the traditional central inverter approach, where many panels are connected together in series on the DC-side and then run en-masse to a single larger inverter.

In the aftermath of the 2001 Telecoms crash, Martin Fornage of Cerent Corporation was looking for new projects. When he saw the low performance of the string inverter for the solar array on his ranch, he partnered with another Cerent engineer, Raghu Belur, and they formed PVI Solutions. The two tapped Paul Nahi to be CEO at the end of 2006, and Fornage, Belur and Nahi formed Enphase Energy, Inc. in early 2007. Thereafter, the first prototype microinverter was developed. With approximately $6 million in private equity by 2008, Enphase released its first product, the M175, to moderate success. Their 2nd generation product, 2009’s M190, was far more successful, with sales of about 400,000 units in 2009 and early 2010. Enphase quickly grew to 13% market share for residential systems by mid-2010, aiming for 20% by year-end.

They shipped their 500,000th inverter in early 2011, and their one millionth in September of the same year. The 3rd generation M215 was released in the summer of 2011, and had sold over a million of all models in 2011, bringing their installed base to 1.55 million inverters and 34.4% market share. A 4th generation, the M250, was released in 2013.

As of 2012, their inverters captured 53.5% market share for residential installations in the US, which represents 72% of the entire world micro-inverter market. This makes them the sixth largest inverter manufacturer, of any kind, worldwide.

In 2012 and 2013, Enphase experienced increasing pricing pressure due to rapidly falling prices in the inverter market. Market leaders faced market share erosion in the face of newer companies, most of them from the far east. However, in 2019, Enphase remains the leading supplier of solar microinverters globally.


All Enphase microinverters are completely self contained power converters. In the case of a rooftop PV inverter, the unit will convert DC from a single solar panel into grid-compliant AC power, following the maximum power point of the panel. Since the “S” series microinverters (e.g. S280) all Enphase microinverters have been both Advanced Grid Function and Bidirectional power capable. This allows a microinverter to produce power in the DC-AC direction, for solar applications, or in the DC-AC and AC-DC directions, for battery use. The microinverter(s) in the Enphase battery products are exactly the same units as installed on the roof, with only software settings changed.

Legacy Products

The M175 was their first product, released in 2008. It was designed to output 175 Watts of AC power, but is capable of up to 5% over that. The M175 was packaged in a relatively large cast aluminum box, similar to the boxes used on cable tv amplifiers seen on telephone poles. Wiring was passed through the case using compression fittings and the inverters connected to each other using a twist-lock connection. A limited number of M210 models, based on the same generation system, were also available for a limited time.

Due to a high level of failures the M175 was recalled and replaced by the M190 in 2009. The M190 offers a slightly higher power rating of 190 Watts (peaking to 199). The system was packaged in a much smaller case, this time filled with epoxy potting material to handle heat dissipation, and built-in cable connections replacing the earlier compression fittings. The system was otherwise similar, using the same connectors and cabling as the M175, and the two designs could be mixed in a string. Like its predecessor the M175 the M190 has also been plagued by a high failure rate.

Around the same time the company also released the D380, which was essentially two M190’s in a single larger case. For small inverters like the M190, the case and its assembly represented a significant portion of the total cost of production, so by placing two in a single box that cost is spread out. The D380 also introduced a new inter-inverter cabling system based on a “drop cable” system. This placed a single connector on a short cable on the inverter, and used a separate cable with either one or three connectors on it. Arrays were constructed by linking together up to three D380s with a single drop cable, and then connecting them to other drop cables using larger twist-fit connectors.

In 2011 the entire lineup was replaced with the 3rd generation M215, combining the features of the M190 and D380 while improving reliability. Like the M190, the M215 was a single inverter, now in a much smaller box. Like the D380, the M215 used a trunk cabling system with short connector cables on the inverters. However, instead of one or three-drop cable, the M215’s Engage system, used a long roll of cables with connectors spliced into it. The installer cuts the Engage cable to the required length, and then caps the open ends that result.

In 2013 the M250 was released, offering a new grounding system (Integrated Ground – IG) that eliminates the otherwise NEC – required external grounding conductor, increased reliability, and increased efficiency (96.5%), along with a rating bump to 250W. Whereas previous models were all named after the maximum power rating, the M250 actually refers to its peak power. Using the same convention the M190 would be called the M199. The M250 is otherwise identical to the earlier M215 (which also was upgraded with IG) and compatible with the same Engage cabling system.

All Enphase models use power line communications to pass monitoring data between the inverters and the Envoy communications gateway. The Envoy stores daily performance data for up to a year, and, when available, allows Enphase’s Enlighten web service to download data approximately every 15 minutes. Customers and installers can review the data on the Enlighten web site.

Current Products

In 2015 the company launched its fifth generation of products. The S230 and S280 microinverters have the highest efficiency for module-level power electronics at 97%, offer advanced grid functionality like reactive power control, and comply with regulatory requirements like Electric Rule 21 in California and Rule 14H in Hawaii. The next-gen Envoy-S offers revenue-grade metering of solar production, consumption monitoring, and integrated Wi-Fi. The company also moved into home energy storage with its Storage System featuring an AC Battery, a modular, 1.2kWh lithium-iron phosphate offering aimed at residential users that is part of a Home Energy Solution. The Home Energy Solution launched in Australia in mid-2016.

2017 began the introduction of the new IQ architecture, which uses a new cabling system. Two conductors, down from four, are integrated and compliant with electrical codes due to the use of GFCI, no need for a neutral and no conductive materials in the enclosure. The initial products were the IQ6 and IQ6+, followed in 2018 by the IQ7. In 2019 the IQ8 series will enable continuous power production during grid outages during daytime without the need for batteries.

Q Cells

Hanwha Q Cells (commonly known as simply Q CELLS) is a major manufacturer of photovoltaic (PV) solar cells. The company is headquartered in Seoul, South Korea, after being founded in 1999 in Talheim, Germany, where the company still has its engineering offices. Q Cells now operates as a subsidiary of Hanwha Solutions, an energy and petrochemical company.

Q Cells has manufacturing facilities in China, Malaysia, South Korea, and the United States. The company was the sixth-largest producer of solar cells in 2019, with shipments totaling 7.3 gigawatts.


In 1999, Anton Milner, Reiner Lemoine, Holger Feist, and Paul Grunow established Q Cells in an area of Thalheim, a part of former East Germany that had seen 50,000 people lose their jobs after German reunification. On 23 July 2001, the company produced its first working polycrystalline solar cell on its new production line in Thalheim. Q Cells would grow to become one of the world’s largest solar cell manufacturers, employing Over 2,000 people and encouraging other companies to open facilities in the surrounding area, which would come to be known as “Solar Valley.”

The company went public on 5 October 5, 2005, listing on the Frankfurt Stock Exchange. High share prices during the initial public offering poured money into the company and made the founders wealthy. Lemoine died in 2006, and shortly thereafter, Fest and Grunow left the company to go back into research. Only Milner remained and served as the company’s CEO.

In 2005, Q-Cells established the CdTe PV manufacturer Calyxo. In November 2007, Q-Cells agreed a deal with Solar Fields, which intellectual property and assets were merged into Calyxo’s newly established subsidiary Calyxo USA. In 2011, Solar Fields took over Calyxo.

In 2008, Q-Cells acquired 17.9% stake in Renewable Energy Corporation. This stake was sold in 2009. At the same year, Q-Cells’ subsidiary Sontor merged with a thin-film company Solarfilm.

In June 2009, the company acquired Solibro, a joint venture it had established in 2006. Solibro manufactured thin-film solar cells based on copper-indium-gallium-diselenide. These modules were marketed until the sale of Solibro to Hanergy in 2012.

Q Cells was hit hard by the Great Recession in late 2008, with share prices slipping from over 80 euros to under 20. In response, the company laid off 500 employees. Milner resigned as CEO in early 2010, and by the end of the year, the company’s finances appeared to stabilize. Just a few months later, in 2011, the global solar cell market crashed, with production overcapacity driving prices extremely low. Q-Cells saw sales slide by around 1 billion euros, ran a loss of 846 million euros and on 3 April 2011, the company filed for bankruptcy.

In August 2012, the Hanwha Group, a large South Korean business conglomerate, agreed to acquire Q Cells, saying that it presented synergy opportunities. In 2010, Hanwha had purchased a 49.99% share in Chinese manufacturer Solarfun which had been renamed Hanwha SolarOne. SolarOne had been producing solar cells for Q Cells under contract.

Due to high costs, production in Germany ceased in 2015, with Hanwha moving the work to its SolarOne facilities in China and newly opened manufacturing facilities in Malaysia and South Korea. In 2019, Q Cells opened another manufacturing facility in the United States.

In recent years, Hanwha has since worked to simplify the structure of units, merging SolarOne into Q Cells in December 2014, merging Q Cells and the company’s Advanced Materials (petrochemicals) group in 2018, Q Cells & Advanced Materials acquired a solar company operated by the Hanwha Chemicals group in 2019, and in 2020 Hanwha Q Cells & Advanced Materials merged with Hanwha Chemical to form the Hanwha Solutions group.


Q Cells develops and produces mono– and polycrystalline silicon photovoltaic cells and solar panels. It produces and installs PV systems for commercial, industrial, and residential applications and provides EPC services for large-scale solar power plants.

The company’s engineering offices are located at the original headquarters in Thalheim, German. In the United States that have a production facility in Dalton, Georgia in the United States.

LG Chem

Often referred to as LG Chemical, is the largest Korean chemical company and is headquartered in Seoul, South Korea. It was the 10th largest chemical company in the world by sales in 2017. It was first established as the Lucky Chemical Industrial Corporation, which manufactured cosmetics. It is now solely a business-to-business company (consumer products division was spun off into LG Household & Health Care).

The company has eight factories in South Korea and a network of 29 business locations in 15 countries. The Financial Times reported on April 2, 2017, that LG Chem would be expanding battery production in China. At the time, China accounted for one-third of the company’s total sales. In April 2019, LG Chem sued rival SK Innovation for allegedly stealing trade secrets for manufacturing electric vehicle batteries.

Business and product areas

LG Chem has three main business areas:

  • Basic materials and chemicals
  • Information technology and electronics materials
  • Energy solutions

Basic materials and chemicals

LG Chem is a supplier of petrochemicals ranging from basic distillates to specialty polymers. For example, it is a large producer of common plastics such as acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile resin (SAN), and polyvinyl chloride (PVC). It also produces raw materials and liquids, including plasticizers, specialty additives, alcohols, polyolefins, acrylic acid, synthetic rubber, styrenics, performance polymers, engineering plastics, elastomers, conductive resins, and other chemicals.

Information technology and electronics materials

LG Chem supplies display and optical films, polarizers, printed circuit materials, and toners. It also supplies LCD polarizers, which are multi-layer sheets of film applied to the top and bottom surfaces of TFT-LCD panels to transmit the light from the backlight unit through the panel, and 3D FPR (film-type patterned retarder) film, which enables three-dimensional viewing.

Energy solutions

LG Chem completed development and began mass production of Korea’s first lithium-ion batteries back in 1999. At the end of 2011, LG Chem was the world’s third-largest maker with an annual production capacity of 1 billion cells. It is also a supplier of automotive battery for electric vehicles, such as the Ford Focus, Chevrolet Volt and Renault ZOE.

LG Chem Michigan is a wholly owned subsidiary of LG Chem based in Holland, Michigan which operates a plant to manufacture advanced battery cells for electric vehicles in Holland, Michigan. The US$303 million Holland plant received 50% of its funding from U.S. Department of Energy matching stimulus funds, and started manufacturing battery systems in 2013. The plant can produce enough cells per year to build between 50,000 and 200,000 battery packs for electric cars and hybrids such as the Chevrolet Volt by General Motors, the Ford Focus Electric, and upcoming plug-in electric vehicles from other carmakers. Its research and development arm, called LG Chem Power, is based in nearby Troy, Michigan. LG Chem Power and LG Chem Michigan were originally one company called Compact Power, Inc.

Both the Chevrolet Volt and the Ford Focus Electric initially used cells manufactured in Korea by parent LG Chem and then later switched to cells produced in LG Chem Michigan’s Holland plant once it opened.

In September 2020, LG Chem unveiled its plan to publicly list its energy division under the name of LG Energy Solution by December.

Tesla subsidiary Tesla Energy develops, builds, sells and installs solar energy generation systems and battery energy storage products (as well as related products and services) to residential, commercial and industrial customers.

The subsidiary was created by the merger of Tesla’s existing battery energy storage products division with SolarCity, a solar energy company that Tesla acquired in 2016.

Tesla Energy’s generation products include solar panels (built by other companies for Tesla), the Tesla Solar Roof (a solar shingle system) and the Tesla Solar Inverter. Other products include the Powerwall (a home energy storage device) and the Powerpack and Megapack, which are large-scale energy storage systems.

In 2020, the company deployed solar energy systems capable of generating 205 megawatts (ranked third in U.S. residential solar installations) and deployed 3 gigawatt-hours of battery energy storage products.

Tesla Energy Software

Tesla has developed a software ecosystem to support its energy hardware products. Autobidder, Powerhub, Opticaster, Microgrid Controller and Virtual Machine Mode are the products that Tesla offers.


SolarEdge Technologies, Inc. is an Israel-headquartered provider of power optimizersolar inverter and monitoring systems for photovoltaic arrays. These products aim to increase energy output through module-level Maximum Power Point Tracking (MPPT). Established in 2006, the company has offices in the United States, Germany, Italy, Japan, and Israel. It is incorporated in Delaware.


SolarEdge was established in 2006 by Guy Sella, first CEO and Chairman, Lior Handelsman, VP of Product Strategy & Business Development, Yoav Galin, VP of R&D, Meir Adest, VP of Core Technologies and Amir Fishelov, Chief Software Architect.

The company is venture capital backed and investors include GE Energy Financial Services, Norwest Venture PartnersLightspeed Venture Partners, ORR Partners, Genesis Partners, Walden International, Vertex Ventures Israel, JP Asia Capital and Opus Capital Ventures.

At the end of 2009, the company started mass production of its products by electronic manufacturing services provider Flextronics International Ltd.

In 2010, the company shipped an estimated 250,000 power optimizers and 12,000 inverters – amounting to a total generation of 50 megawatts and 70% of the power optimizers market.

In March 2015, SolarEdge had an initial public offering of 7,000,000 shares of its common stock at a price to the public of $18.00 per share, raising $126 million. The shares began trading on the NASDAQ Global Select Market under the ticker symbol “SEDG.” Goldman Sachs and Deutsche Bank acted as joint book-running managers for the offering.

Following a battle with cancer, founder Guy Sella died in 2019. Former Global Sales VP Zvi Lando, was appointed acting CEO.

Schneider Electric Partnership

In October 2020, SolarEdge has partnered with Schneider Electric. This alliance is planned to provide a cohesive electricity environment for installers and device owners, while also accelerating solar installation experience across the region.

Introduction of Square D Energy Center

The Square D Energy Center is operated by Schneider Electric’s Wiser technology, along with Solaredge’s Energy Hub Inverter with Prism Technology, for home automation and electronic energy storage.


Traditional PV systems are typically characterized by a centralized inverter or string inverter architecture*. In this topology the inverter performs MPPT for large quantities of solar panels as a whole. Since the solar panels are connected in series to form strings, the same current must flow through all the modules, so the solar inverter continuously adjusts the electric current in the system to find the average optimal working point of all the modules. As a result, potential power may be lost whenever a mismatch exists between modules.

*Panel mismatch is unavoidable in many cases, due to panel manufacturing tolerance, partial shading, uneven soiling, or uneven tilt angle. In addition, power may also be lost due to slow tracking of dynamic weather conditions caused by moving clouds, and on extremely hot or cold days when the system DC voltage may exceed the inverter’s permissible input voltage range*. These factors cause small losses in yearly yields, but they are present. Other drawbacks of traditional PV systems include:

  • System design is constrained by the need to match all strings’ length and orientation
  • Monitoring visibility and fault detection are limited to the inverter (or in some cases, to the string level)
  • High DC voltage is present as long as the sun is up, posing a possible risk of electrocution to installers, maintenance personnel and firefighters*

These drawbacks, however, can be mitigated by newer string inverters with advanced electronics and features such as dual, shade-tolerant and improved MPPT.


In October 2018, SolarEdge announced agreements to acquire a major stake in Kokam, a South Korean provider of Lithium-ion battery cells, batteries and energy storage solutions.

In January 2019 SolarEdge announced the acquisition of a majority stake in SMRE – an italian EV/Powertrain manufacturer. SMRE has since been renamed to SOLAREDGE e-MOBILITY SpA.
