Solar Heating

Contrary to popular belief the amount of solar radiation received by the UK is enough for solar water heating to be a viable supplement to existing domestic water heating. Perhaps surprisingly the UK receives 65% of the amount of solar radiation that is received by the south of Spain. The radiation in the UK is made up of direct radiation on sunny days, which accounts for around 40%, and diffused radiation on cloudy days, accounting for 60% of the total.

Summer will provide the largest amount of radiation over the year but a useful contribution will be provided by other seasons.

As an indication, a well sized typical installation will provide the following proportion of the household domestic hot water requirement.

Season % of requirement fulfilled by solar
Summer 80 – 90%
Spring & Autumn 40 – 50%
Winter 20 – 30%

This translates to roughly half of the typical annual domestic hot water requirement.
