All went very smooth; still happy now years later

I had 20 PV panels (for electricity) and 2 thermal panels (for solar hot water) installed in 2010. I shopped around through a number of suppliers and Solar Energy Services (SES) seemed to be the best all around value. I also appreciated that one company could do everything I needed. The install went very smoothly and they were good about communicating with me. There were a few issues that arose with county inspectors but SES took care of getting everything squared away and getting me registered for all the credits I was eligible for. Since then, my system has worked very well with essentially no maintenance. Three of the microinverters did fail on the PV panel, but SES contacted me (they noticed the problem from their monitoring) and said they were all ready to come replace them; under-warranty no charge. So overall I am very satisfied.

Excellent solar company

When I decided to install solar panels on my home, I interviewed 3 companies. Solar Energy Services was the best. A truly knowledgeable sales rep helped pick the best set up for me. The installers did a great job, and the office staff were so helpful in getting all the necessary government paperwork completed. Two years on, and I'm still very satisfied with my system.

fantastic local company!

We have had a great experience with Solar Energy Services. Any technical issues we have encountered have been handled quickly and they are able to explain things in understandable terms. I looked at a lot of companies when searching for solar panels and Solar Energy Services were the only ones that didn't make me feel pressured to sign on the dotted line right now- they educated me, told me to call with questions, and since they are local are easy to contact and come out to check on the system if needed.

Tried and True: Ask the Experts

From sales to installation, you have a LOT of questions. Do your research and ask. These people know what they're talking about. With more than 30 years of experience, they've seen what works, how it works, and make it their business to know how to design a system that works for you. Sales is accessible and knowledgeable. Design evolved to suit our house with minimum visibility; Installation went steadily, but with some delays. We bought both thermal hot water system, and PV, and are very happy with the quality of materials, workmanship, payback period, tax deductions, and "going green" as much as we can.
