Residential solar installer Posigen announced it will cease most of its operations through the United States, effective immediately.
The company cited “significant financial difficulties” in a WARN Act termination notice to its employees. The shutdown of operations includes the closure and permanent layoffs at its facilities in Plymouth Meeting and Conshohocken, Pennsylvania.
The solar installation business serves customers in Massachusetts, Connecticut, Rhode Island, New Jersey, Pennsylvania, Louisiana and Mississippi. It also offers battery energy storage installation and energy efficiency services.
Posigen said it is seeking sufficient capital from its lender to continue remaining operations and/or effectuate a sale of its remaining business. The company said if it fails to do so, it will close all operations.
The installer said it grew its operations rapidly, which later led to a liquidity strain. Amid market slowdown, it was forced to use its working capital to advance contracted solar projects to completion, which pressured liquidity. The company then made a missed interest payment on its credit facility in favor of preserving capital to pay its channel partners and pay operating expenses. Its lender then exercised its rights to freeze cash and issue a notice of default on Posigen’s credit facility. This caused a sudden and unexpected interruption in the company’s business operations, said the termination letter.
“The company has now determined that it is unable to secure sufficient capital to continue most of its operations and avoid the need for significant headcount reduction,” said the letter.
Posigen, a Certified B Corporation, employed about 500 people nationwide, with about 100 in Louisiana, as of June 2025.
“My heart goes out to hundreds of my colleagues locally, nationally, and abroad who lost their jobs this past weekend,” said Tony Salpietra, state incentive coordinator, Posigen. “If your company is looking for amazing, principled people who will go above and beyond to fulfill their mission, I urge you to seek out former Posigen employees and get them before they find something else. You won’t be disappointed.”
Residential market decline
Residential solar in the United States is experiencing a broad market decline. Faced by macroeconomic challenges and shifting sands of state and federal policies, an industry once defined by double-digit growth in installations is experiencing falling demand.
Residential solar installations declined 31% in 2024. Over the last year, industry titans like SunPower, Sunnova, and Mosaic Solar have filed for bankruptcy.
Looking ahead the residential solar industry will need to find new ways to lower costs to thrive in a harsher regulatory environment.
One pathway is pursuing lower soft costs, or costs not tied to hardware. The Solar Energy Industries Association (SEIA) said over 65% of the cost to install residential solar is related to soft costs like paying sales teams, securing permits, grid connection costs, and more.
The United States may find a path forward by pursuing market conditions like Australia, where over 40% of homes in some regions have rooftop solar. Soft costs are far lower in the nation, and average residential solar installation cost was $0.89 per W, more than $2.00 per W cheaper than both Canada and the United States.

What”s going on with the new ROof and Installation of my ystem?
One inflation choked off funding for the solar power industry. Two high interest rates from the federal reserve made solar projects unaffordable. Three Trump killed all federal funding for solar projects. That was not one big beautiful bill. Only one that will survive is first solar FSLR. This won’t grow till 2029 when Trump is gone.
They built solar companies, based on the fact that the federal government would provide the incentives to make it cost-effective enough for consumers to install it, the market’s been falling apart because people are realizing that it is not cost-effective, and now that the tax credits are gone the majority of it is going to collapse, unfortunately.
This doesn’t make any sense.Now is the best time to get in solar because of all the data center they’re gonna be using all the data centers that are gonna be spring up all over that will cause brown outs and blackoutso no electricity for the homeowner but all the electricity for the data centers. There needs to be a way for the homeowner to be able to have afafordable electricity run by the Sun and not dependent on the grid.
They install the system on my roof and destroyed my roof when they left they were shingles all over the place the roof faded from the installation that was not done correctly it needs to be so many inches off of your shingle roof my roof is now leaking they repossessed the solar panels because we are involved in a ownership transfer they charge $25,000 for something that is only worth about $5,000 their fees are too high per month and I never will agree with how they calculate your credits they’re stealing from the power companies they’re stealing from us and they’re stealing from the government and they’re rolling in the dough when is there ever going to be accompany that doesn’t cheat their customers lie to their customers overcharge their customers that is the problem with solar also these panels do not last but maybe 5 years and then your solar uptake is diminished almost in half so there’s no replacement there’s no maintenance they never maintain them they don’t clean them they just put them on your roof destroy your roof on your house and rake in the dough there’s no reason why these systems can’t be installed for around $5,000 including battery backup which they never provided not $25,000 we calculate how much kilowatts and their figures are always in their favor I put a meter on mine and I calculated that it was producing about three times what they were giving me for a credit these are criminal organizations cheating people lying to people destroying people’s property and I asked them to fix my roof I told them I don’t care if they just put a coating on it or something they refuse to after all the money we paid them the next time I do this I will install my own system there is nothing complex about these systems the only complicated portion of it is feeding it back to the power grid but the next one I install I’m just going to use the power grid as backup and just run my house off of multiple 300ah batteries most conservative families can run their house off of like a 3000 watt system with battery backup probably about 1500 ah batteries will run everything in the house in about a 10,000 watt inverter will run almost all of your appliances if you install the right type of impliances like German products instead of Chinese products that just waste energy like crazy I have an RV that I installed my own system on it’s only about 1600 Watts with 5000 w inverter and it runs the see runs everything the system only cost about less than $3,000.. I could even plug my house into my RV and run almost everything in the house refrigerator freezer mini split units window units one of the things that you have to do is buy appliances that don’t have power surge circuit boards once you do that the amount of Watts that you use is so much less the technology of these low surge units has been out there for about 25 years they put them on all German appliances the problem with the solar systems is when you turn on your ACS it surges thousands of Watts more than it’s supposed to and that’s what burns all the electricity a simple circuit board change out fixes that problem or either buy the appliances with the appropriate non-surge circuit boards all of our appliances are completely and utterly a scam and if we made things in America like Germany does we can make them extremely efficient because that energy star sticker on there means nothing for example if you have a 120 watt refrigerator this thing will surge up to 800 watts which is absolutely ridiculous and that’s what runs up your electricity it never needs to do these power surges and that’s what burns up your electricity bill and it’s being done deliberately
