Energy is being talked about more and more these days. ZTC Holding therefore focused on this important area. Our company brings you quality technologies for the production of energy from renewable sources, such as solar modules, solar collectors, heat pumps. Thanks to the selection of the highest quality components from Germany, Norway, Taiwan, but also from Chinese production, we guarantee top quality with guaranteed return and long-term vitality of the delivered systems. We offer you the use of the greatest potential (in the sense of the amount of energy that renewable sources can provide us), namely the direct use of solar radiation to produce heat or electricity. It is probably the only renewable source that, if necessary, could cover all current energy needs in the long term. Thermonuclear reactions take place in the Sun. These reactions convert solar hydrogen into helium, releasing large amounts of energy. Energy is transmitted from the Sun to Earth in the form of radiation. The energy input from the Sun is approximately 1300 W/m2 at the distance at which the Earth is located.
