El Cajon Solar Power: Thunderbird Products

Thunderbird Products, a leading sheet metal manufacturer based in El Cajon, hired Sullivan Solar Power in 2016 to install a large solar power system at the company facilities. The 74.43 kilowatt-AC system will generate a 25-year savings of more than $1.4 million for the company and produce more than 135,000 kilowatt hours each year. The system was Sullivan Solar Power's largest in the El Cajon area and brought our total installed solar power in the area to an impressive 1.5 megawatts.


This Private Commercial solar power installation by Sullivan Solar Power is part of the solar energy revolution and generating clean, renewable electricity for Thunderbird Products. On average, each year a solar energy system this size will:

  • Generate 111,651 to 148,868 kilowatt hours of clean renewable solar power.
  • Avoid the creation of 184,596 pounds of harmful carbon dioxide released into our air.
  • Provide the system owner with $32,751 in Solar Power Savings.
