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.
Solar power inverters are a part of solar electrical systems that help convert the sun's energy into usable power. The solar panels on homes and businesses are made up of small groups of semiconductors that react to sunlight by freeing electrons.he reason solar inverters are necessary is because DC and AC power work differently. In DC power systems, an electrical current only flows in one direction. In AC power systems, the current moves in both directions.
