seedlings grown for 10 years.
gallons of gasoline consumed
bottles of BBQ propane burned.
Solar Power System
The solar array is located at High Tech High Chula Vista and is owned by San Diego Gas & Electric (SDG&E). It is a part of the sustainable design of the school itself which will be used as a three-dimensional textbook. The school’s rooftop solar panels are owned by SDG&E and provide renewable power to the community.
The solar system, installed by Helio Energy Solutions, is a milestone for SDG&E because it puts the utility at over one megawatt of solar installed on highly energy efficient buildings throughout 12 solar projects in San Diego County. It is also the third largest solar system in Chula Vista.
With 640 solar modules from Mitsubishi, the solar power system will produce 172,114 kilowatt hours (kWh) of renewable electricity per year.
