About Us


Since 1985, Berkshire Photovoltaic Services Inc. (BPVS) has pioneered off grid and on grid PV systems originally in an area stretching from Washington DC to the islands of Maine. We’re known for innovative solutions and hybrid designs which utilize battery storage so sites can go “off grid” when they are “on grid” or power dedicated loads. Now our new turn key design and install projects focus on the region surrounding the Berkshires of Massachusetts. We always service our own installations wherever they are and are often called on to diagnose and repair problem PV systems orphaned by others.


BPVS is fully licensed (MA HIC 131996) and insured for commercial, institutional and residential PV Systems. All of our installations are fully permitted and approved. BPVS has helped pave the way for PV acceptance by installing the first (and often second, third and fourth) solar electric systems in over 90 jurisdictions and several utility territories. 


Many of the systems featured on this site were funded in part by New York State Energy Research and Development Authority (NYSERDA) and Massachusetts Renewable Energy Trust Fund Programs. BPVS has provided design and installation support for Electric Utilities, National Renewable Energy Lab (NREL), Department of Energy (DOE), United States Department of Agriculture (USDA) grant recipients and research programs. Our mission is to provide safe, efficient and durable PV Systems.
