Green Arch Solar is a full service residential and commercial solar system installer that specializes in building efficiency. We handle all facets of the project from planning, coordination, construction to interconnection. We drive down costs by outsourcing design, engineering and analysis to our strategic partners. We also examine and evaluate your home or buildings thermal inefficiencies and offer solutions to fix these problems. This allows us to reduce the size of the PV installation thus reducing the overall project cost. Since most cities do not offer a feed in tariff, repayment for excess energy provided to the utility grid, understanding the required size of your PV system is critical in avoiding “gift” energy provided to the utility company, at no cost to them.
