The list ranks applicants according to their influence in the solar market in 2013.
The list details the location of a company, how many people it employs, its primary market (utility, residential or commercial), as well as its primary service (EPC, developer, rooftop installation, construction, thermal systems, non-profit, off-grid projects or electrical).
Ranks are determined by the number of megawatts a company installed in 2013. In some cases, companies reported megawatts for which they were a sub-contractor. If two companies reported the same 2013 numbers, they were sorted by total megawatts installed.
The 2014 Top 400 Solar Contractors list features companies working in four markets – utility, commercial, residential and off-grid – and in varying capacities. From residential rooftop installers to construction firms building multi-megawatt projects, the Top 400 Solar Contractors list recognizes the heart of the solar industry.
