Solar Power World, the industry’s leading source for technology, development and installation news, presents the 2015 Top 500 Solar Contractors list. The list ranks applicants according to their influence in the industry in 2014.
The list details the location of a company, how many people it employs, its primary market (utility, commercial, residential or off-grid), as well as its primary service (EPC, developer, rooftop contractor, construction firm, electrical subcontractor, non-profit installer or solar hot water installer). Ranks are determined by the number of megawatts a company was involved with installing in 2014. If two companies reported the same 2014 numbers, they were sorted by total megawatts installed.
Solar Power World thanks our 2015 Top Contractors Advisory Panel and SolarReviews for their help in verifying installation claims.
