Gregory the Great School: San Diego Commercial Solar Power

St. Gregory the Great in the Miramar Ranch North community of San Diego opened in 1985 and the parish school opened in 2009, making it a much newer addition to the San Diego County Catholic Diocese. The school and church are located in two separate buildings, so the church will receive a solar power system installed on a carport and the school will receive a roof-mounted solar panel array. Construction is slated to begin in April or May 2017. When installed, the combined solar energy systems will help save Gregory the Great more than $1.4 million over the first 25 years of going solar.


This Catholic Diocese solar power installation by Sullivan Solar Power is part of the solar energy revolution and generating clean, renewable electricity for Gregory the Great School. On average, each year a solar energy system this size will:

  • Generate 95,507 to 127,342 kilowatt hours of clean renewable solar power.
  • Avoid the creation of 157,904 pounds of harmful carbon dioxide released into our air.
  • Provide the system owner with $28,015 in Solar Power Savings.
