AST installed my Photovoltaic Solar system 5 years ago. I have been very pleased. The crew was supervised by Scott Johnson himself, and they worked in the frigid cold to get the system in on time as promised. In the 5 years, I have only had one sensor go bad and they had it fixed within a week. My original return on investment was estimated at 7 years and it turned out to be 3 1/2 years. My energy costs are half of what they used to be and I sell the SREC credits each for an additional income source. I cannot say enough good things about this company. On time, on budget. Everything they told me was true and I would recommend them in an instant.

From the day of our first meeting with Scott Johnson, when we were doing the initial feasibility workup for a roof mount solar project on our farm, until the time of commissioning and connection to the grid, the entire crew at Advanced Solar handled the project professionally and sensibly. Proposals, bidding, permitting, grant writing, installation details, unforeseen change orders, and commissioning are areas of project development and completion done exceptionally well.

Solar panels are live and kicked out 36kWh on a winter day yesterday. I am guessing production will be even higher in the summer. On track to cover 100% of electric. Looking forward to nearly nonexistent electric bills and a green-conscious in the near future! Thanks Advanced Solar and MD SUN!
