battery made it through the blackout

We lost power for three days in Columbia County after a snowstorm but our house still had heat, lights and outlets thanks to the solar panels on the roof and the battery Kasselman installed in the basement. We stayed warm and comfortable!

Exceeded all expectations

Kasselman solar exceeded all expectations from start to finish. The design team worked with me on how it would look and how it would operate. There was no high pressure sales what so ever. The price was spot on. Even in winter I can see the savings on the app on my phone (which also won over my skeptical wife) The install was perfect and with a focus on safety. They stopped due to freezing rain. Smart since they’re on a slippery roof. The electricians were polite and respectful and worked with the design of the house rather than a just get it done attitude. Brandon Frey was my project manager and he was top notch. Responsive and polite and friendly. He knew every step of the process and had follow through on everything. I highly recommend working with this group for any solar or electrical project. ⭐️⭐️⭐️⭐️⭐️+

Great experience

Everything about our installation went smoothly and according to plan! Kasselman has been responsive and has followed up to make sure everything is working properly. I'd highly recommend them!

Professional experience

I'm completely satisfied with my system. David Kowalsky got me the best deal of the companies I looked at. Installation was easy and on time. Having a project manager (Jenina Guzman) was very nice because you have a single point of contact for any questions. I would recommend Kasselman.

Very happy with my solar panels!

Kasselman was one of six solar companies I contacted and was the one I chose. Based on my energy consumption they suggested 16 panels. I said why not fill that side of my roof with panels, as many as you can fit? Which turned out to be 22. Which is great, because when I get an electric car I still won't have to pay for electricity. And tax benefits pretty much cut the cost in half. They kept me apprised every step of the way (and my village's building inspector took only a couple of days to turn around the paperwork). There was one glitch but it was minor- they were waiting for something from the building inspector, but when I called him to follow up he said no, just go ahead. I signed my contract mid-July and before the end of August we were up and running (Con Ed takes about a week to approve turning on the system once it's approved by the electrical inspector). Way faster than I expected. So far for Sept-Dec the panels have produced 21% more than Kasselman's estimates. So I'm thrilled. May never have to pay an electric bill again (except for a $19 a month connection fee). Happy to answer questions if anybody wants to email me (as long as I don't get overwhelmed with emails) Oh, one more thing- the inverters they chose were the current generation. I didn't know it at the time but the company that was my second choice would've installed inverters that are one generation older. The ones they used, from Enphase, come with an app so you can see exactly how much you're producing and consuming, in 15 minute intervals. You can even look panel by panel if you want.

Pleasant, fast, well done, effective

Kasselman solar designed and installed my solar power system. They obviously knew what they were doing from start to finish and did a great job of it! They worked so efficiently and were impressively thorough in testing and fine tuning details. The communication was excellent. My system is functioning as promised, this first summer lowering my electric bill to the bare minimum. The people who did the work were all very professional, respectful and pleasant. I feel like I made the best possible decision choosing Kasselman Solar to install the solar power system.
