Sustainable Energy Systems LLC

In mid-March 2015, Sustainable Energy Systems (SES) installed our solar pv system and our experience was positive. The salesman provided good education and answered all our subsequent questions while never being pushy. SES negotiated a bulk purchase agreement with a non profit and that resulted in a sizable discount. The cost per watt was very competitive. The installation team was very professional and friendly. Despite the steepness of our roof and the tight array design, they finished in three days. The follow up regarding connection to the grid and paper work for the rebate was also very timely. By early-April we were up and generating. During the following months, we have been generating more than we use so our utility bills have been only for distribution and taxes, under $6/month. Other questions we have had regarding the monitoring software have been answered promptly. An all around great experience.

This project was the second time we have installed solar on our home and ten vendors were invited to submit proposals. Some vendors shied away because of a metal roof (panels actually on our barn); some lost out because they viewed the needed trenching to the house as a homeowners responsibility either in terms of contracting or hitting possible existing underground electric and water lines or re-seeding when done. Some eliminated on type of panel we preferred and others simply because of cost too high.
We got down to two bidders and Sustainable stayed with us the whole time, patiently answering our seemingly endless stream of questions and not once saying a negative word about other companies (a practice other bidders should have followed!)
From designing, refining, installation to follow up after wards, a very smooth and positive experience for us. Everyone was easy to work with; gladly answered our questions; kept us informed as to install schedule; and promptly responded to follow up issues to reach swift resolution.
We highly recommend Sustainable Energy Systems and plan to return to them if we find expansion of our current system is needed, which they incorporated into their design without hesitation.

My husband and I could not be happier with the entire process with this company. Starting with the knowledgable sales manager, who answered all of our many questions and addressed all of our concerns. To their entire installation and technical team. We love this company! We have had our panels for about 5 months and there have been zero issues and our electric bills have been non existent! I would say that start to finish the process was smooth and positive and I would recommend Sustainable Energy Systems to anyone ! We sat and obtained quotes from bigger companies but in the end we made the best decision!
