Small-scale solar systems, defined as arrays of less than 1 MW, accounted for about 37% of total solar photovoltaic (PV) generation in the US last year, according to the US Energy Information Administration (EIA).
This category includes residential installations with an average size of around 5 kW, commercial systems that average closer to 200 kW, and industrial systems. Based on EIA's estimates, revealed on Thursday, the share of residential rooftops in total small-scale PV generation increased to 52% in 2016.
Small-scale PV output as a whole almost doubled from 2014 to 2016, but its share of total PV generation declined as utility-scale PV generation grew at a faster rate.
California accounted for 43% of the country's small-scale PV output in 2016, followed by New Jersey with 9%, Arizona, Massachusetts, New York and Hawaii.
