Good experience

I contracted with SES through a Virginia co-op which allowed me to get a discount on buying in bulk with other households. The process took about four and a half months to complete (from the time I signed the contract to the time Dominion approved my system). There we some technical difficulties with modifications to the contract, but Stuart worked through them with me and I am pleased with the process. I am no monitoring production to see how the calculations I was presented fair in the real world.

Stunning support! Willing to go the extra mile!

The entire team at Sustainable Energy Systems went to bat for me. I was fighting to get panels on my roof and had several companies bidding for my install. Sustainable not only took my proposed installation seriously, but went the extra mile to make sure i was getting the right system for me, but also came up with solutions - not excuses on how to get the job done.<br /><br />My roof was "slightly" higher than most, and required a little extra effort to perform the instal. Sustainable Energy Systems exceeded my expectations in every way. I will absolutely recommend them to anyone that asks.

Superior Installers!

These folks know their stuff. Careful research before allowing anyone to mess with a roof is highly advised, and this group passed the test with flying colors! Engineering, materials, beyond the call of duty attention to detail and satisfaction is what I can report. The system is installed beautifully with attention to aesthetics and function. Beyond satisfied!

Good Experience in Solar Installation

I used SES through a group buy. They honored the parameters of the group buy without any hesitation, even though my installation had some complexity that could have been considered extra work requiring extra charge. SES showed me the design during the permitting process and addressed the revisions that I requested. I found their services to be such a good value with my initial installation in 2015 that I contracted with them again in 2016 to expand my system.
