Background

This directory provides potential buyers with independent data on the thermal performance of solar domestic hot water systems that are designed for residential use. The thermal performance is an important factor in the purchase decision since the water heating capacity can vary between systems. However, actual thermal energy output will vary depending on hot water usage, geographical location, and several system installation and operating parameters. Energy output is not the only criteria for selecting a solar domestic hot water system. The cost, expected service life (and warranty), quality of installation, availability of parts and quality of service are also important factors.

All systems listed in this directory have completed certification to CSA Standard F379 "Solar Domestic Hot Water Systems". The ratings in this directory have been determined using the standard day specified in that Standard for the 300 litres/day hot water load. For system models that were not tested, detailed computer models were developed and the standard day test was simulated using TRNSYS software.
