What is a Solar Collector and How Does It Work? A solar collector takes heat energy from the sun and turns it into usable thermal power. It works on the principle of the greenhouse effect. The collector has a see-through cover that lets in the sun''s heat. This heat warms up a plate inside. The warmth then moves to water or air, which we can ...
Using solar thermal collectors in a normal home can generate significant energy savings compared to a home that does not use them. By harnessing the sun''s energy to heat water, solar thermal collectors would significantly reduce the need for traditional water heating systems, which typically rely on electricity or fossil fuels.
