Solar energy system performance evaluation seasonal report for Elcam San Diego, San Diego, California
The solar energy system, Elcam San Diego, was designed to supply domestic hot water heating for a single family residence located in Encinitas, California. The contents of this document have been divided into System Description, Performance Assessment, Operating Energy, Energy Savings, Maintenance and Summary and Conclusions. The system is a Sunspot two tank cascade type, where solar energy is supplied to either a 66 gallon preheat tank (solar storage) or a 40 gallon domestic hot water tank. Water is pumped directly from one of the two tanks, through the 65 square feet collector array and back into the same tank. Freeze protection is provided by automatically circulating hot water from the hot water tank through the collectors and exposed plumbing when freezing conditions exist. Auxiliary energy is supplied by natural gas. The Elcam San Diego solar energy system has three modes of operation.
