We found Sam and his team to be professional and very responsive to questions during the installation process and after our system was activated. Our 18 kV system with 50 Silfab 360 watt 72 cell panels has done a great job and with this additional capacity, Maine Solar Solutions also installed a 45K BTU Fujitsu heat pump with five mini-splits throughout the house. We are toasty warm in winter months and comfortably cool in the summer with very quiet inside units. We initially considered four local companies and chose Sam's company for a variety of reasons. We have been very satisfied with our decision as we continue to enjoy saving on electric costs, home heating oil and liquid propane fuel costs.
