System Sizing

Apricus solar collectors are a supplemental energy source. Solar thermal cannot totally replace traditional energy sources (gas or electricity) as it is not always sunny! A solar thermal system will therefore have a backup boost from electricity or gas to ensure you always have hot water.

A correctly sized solar system can save between 50% and 80% off your annual hot water energy bills, depending on your location and water usage patterns.

By reducing the amount of gas or electricity (or other fossil fuel source) that is used, you are also directly reducing CO² emissions, which is a major factor in helping to combat global warming. Click here for more information on CO² and global warming.

The diagram below provides a general idea of how many collectors are required based on the number of people in the household. A cold climate is somewhere that gets regular snow in the winter, warm winter would rarely go below freezing. In you are in a hot climate (near the equator) then a collector can provide even more hot water.
