The solar thermal system works simply by pumping cold water into the pipes within your solar thermal panels, which are fitted on your roof. The sun then heats up the cold water within the pipes. The now hot water is pumped into your hot water cylinder where it is stored until needed.
Any unused electricity from production simultaneously goes back into the electrical grid. At night or on cloudy days â when your solar power system is not producing more than whatâs needed âelectricity is drawn from the grid as it normally would. In most cases, solar panels produce more than enough energy. In order to maximize your investment and produce as much solar energy as possible, the panels need direct access to the sunâs rays for most of the day. Any shading on a solar power system will reduce its energy output considerably. Air temperatures normally do not affect solar energy systems nor do locations where there tends to be higher snow accumulations.
