This case study was written by Adroit Solar, a solar energy company in California. It profiles a solar thermal installation at the Mission Heights Condominium complex which provides solar thermal water heating to 116 residential units in 3 buildings.
The installed system is an active flat plate, closed loop system. It was installed with incentives from the California State Government through the California Solar Initiative – Thermal rebate program. The heated water in the storage tank pumps into a natural gas system, and has reduced the natural gas usage of the condominium complex by 8,517 therms a year.
