Great people with great communication

From beginning to end i was always kept in the loop as to when to expect what. The salesman was great and straight forward giving me the best lease terms and rate right off the bat (beating another SunPower dealer in the area). The installers were excellent and took great care while working on my house that I just built. They took the extra time and were able to hide all the wiring through the attic area and coming out a soffit in the opposite corner of the house making everything nearly invisible. Really great work that you can tell they put pride in. The system was up and running less than 2 weeks after install and everything seems to be working great! The app is very nice and lets you monitor your system in real time and shows how much enery you have made vs. used. I look forward to having a consistently lower utility bill each month for the next 20 years! (Saving an average of at least $100/month). I have recommended this company to friends and neighbors already.

Earthlight Technologies Review

We hired Earthlight to design and install a SunPower solar system for our house this year (2023). The process is complicated and we found Earthlight very good to work with. Necessary coordination with reviews, permits and inspectors went smoothly. Our energy company, Eversource, was terrific throughout the process. It took about 6-1/2 months from start to completion and we are excited about the install. Earthlight is well organized, helpful, professional and a good company with a good product. I would guess we had contact with about 15 employees from the company from start to finish, they were all very nice and expert. We would not hesitate to recommend them for solar installations. Customers would benefit from Earthlight providing even more upfront explanations concerning the solar panels and equipment since it is a highly engineered technology that can be confusing.

Should have done this sooner

The process overall took almost a year. However it was very much worth the wait. I'd rather pay them money than give it to Eversource. I can't really speak to overall value as of yet. I have not even received my first bill. However the process though long was pretty smooth. The company was generally responsive with a few lags but nothing that caused any concern. The work done on my home was professional and very clean. I just wish we could get a few more panels on the roof.

Why look elsewhere?!

Earthlight, I can’t give enough praise and admiration of being on the receiving end as a customer. This company sent out a representative, her name is Cara She was a breath of fresh air, down to earth and brutally honest with a pinch of sugar. I felt the knowledge and explanation was simple enough to understand and any questions I had I was soon we’ll educated in the field. Pricing was very good comparatively to others I’ve gotten quotes from. The install was very good! The workers are diligent, thoughtful and well versed in their fields! They even take the time to look over the project and house and clean up after themselves!! Trinity left everything a mess, hacked up and nails in my lawn and driveway left me with a flat they denied was by their work… claiming it was due to recent roof work… I was a trinity customer prior, I scouted every other big name company and in the end they were all Chinese. LG is out of the game which is Korean. SunPower is a Mexico/US made brand and produced with smaller electrical components from Malaysia and Philippines. This allows for less headaches for components and delay for parts. Being a more US developed and produced components you have comfort knowing parts are available. The testing and quality and next thing is the warranty! This brand is backed and started in the 70s and early on they supplied solar to the government. Being a long standing company also gives reassurance on the product! I’m over a year now installed and no issues! I’m definitely going to be ordering more panels as we expand our hour projects and going solar has saved us significantly compared to Eversource greedy spikes and rates that’ll never change.

Roof repair

I had a leak in my roof, I called earthlight to have two of my panels removed to get my roof fixed. They came out within three days to remove them. When my roof was all repaired I called them again and they were out within a few days to put them back on. Best customer service ever. I would really recommend them!! I love my soar panels, as I haven't had any issues with them at all so far.
