We speak


Your solar array starts producing power as soon as the solar production meter is installed by your utility, which takes 2-10 business days. You will notice the biggest difference in your bill during the first full billing period in which you have solar.
Bottom line, yes. Solar panels do not need sunshine as much as they need direct unobstructed access to the sun’s UV rays. Your solar panels will still generate power during rainy, cloudy or snowy days, just not as much as they would on a clear sunny day.

Excellent workmanship; great interaction with customer.

Natosi Solar provided clear and helpful advice about design of our ground mount solar array and electric service upgrade. Helped us steer clear of additional investments unlikely to be of real benefit to us. Workmanship was excellent and communication with us was great. Array is working as promoted.

Great people to work with

I can't recommend Natosi Solar enough. The price was reasonable compared to the competition and I liked the idea of supporting a smaller local company over one of the big national companies. They were responsive and easy to deal with from start to finish. The system designers came up with a great plan and clearly explained all the details. They happily sent me a few different quotes to account for potential future extra capacity. The owner came on the initial consult and it was clear that he cared about doing things right - a rarity recently. He could have cut some corners and ran ugly conduit all over my roof, but instead he found a way to run the wiring between a couple of attic spaces. It looks great. The installation crew were on time, friendly, professional and finished early. The system looks great and I've had no problems with operation so far. I will be recommending Natosi to anyone that is interested in solar.

Unmatched Solar Professionals

Natosi Solar was great to work with from start to finish. My project was a bit on the complex side - I have a smaller roof at a few different pitches, wanted to include a timber frame solar canopy to cover my new back porch, and needed enough panels to cover my modest electric bill. Andrew, Rachael and the team made the entire process so easy from pulling all necessary permits to designing the system in full, including the owner, Andrew, coming and hand-planing and erecting all of the beams for the canopy. Their team worked alongside my other contractor (who was building my porch) with ease when building the canopy and the entire solar panel installation portion only took 2 days (something I expected to take much longer with the complexity of where I wanted the panels and how many there were.) Their operations manager, Rachael, has been wonderful to work with and has made the entire process very easy to understand, from what panels will work best for my needs, to helping me understand the solar loan, and how the solar credits work with my electric company. At the end of the day I was left with a beautiful solar system and the exact solar canopy I was hoping for to cover my new back porch (they also made it waterproof too so we are able to use it during less than ideal weather). Natosi Solar is a wonderful local Vermont company who I can not recommend enough.

Andrew was very professional and approachable with explaining different solar systems and answering questions. They did their homework and found that my property lines were different than what I was told. Instead of shutting down the project because my land couldn’t hold an array they found alternatives that are actually better. The team was friendly and skillful the dat of installation. I wholeheartedly endorse this company including their administrative professional Rachel. She’s the voice of calm, clarity, and she knows the business from the inside out.
