Thermal Solar Panels

Solar Panels, also known as "collectors", can be fitted to a building's roof. They use
the sun's heat to warm water, or another fluid, which passes through the panel. The
fluid is then fed to a heat store (e.g. a hot water tank) and helps provide hot water directly or can provide a source of hot water for the central heating system in the dwelling. Solar panels work throughout daylight hours, even if the sky is overcast and there is no direct sunshine. Solar panels can also be used to meet some space heating demand. Ideally the panels should be located on an unshaded, south facing roof at a tilt angle of 30°- 45° to the horizontal. Space will be needed to accommodate an appropriately sized twin coil cylinder for the system and a thermal mixing (anti-scald) valve should also be installed.
