Solar Thermal Energy

The heat of the sun is dead. The solar heating system can cost up to $ 7,000 to install and probably will not save you so much. That is why many people are discussing whether to use a solar hot water heating system. Traditional heating systems are electric, gas, oil and other fuel-powered systems. The solar heating system uses energy from the sun, that is, "solar energy", converts energy into warm water, warms the households, and supplies household hot water.

Solar thermal energy - solar thermal energy is a technique to obtain thermal energy (thermal energy) using solar energy. The solar collector is defined as a low temperature, medium temperature, or high temperature collector by the US Energy Information Agency. Cryogenic collector is a flat plate that is commonly used to heat pool. The medium temperature collector is also typically a flat plate, but it is used to produce residential and commercial hot water. High temperature collectors use sunlight from mirrors or lenses and are commonly used for power generation. STE is different from solar power which converts solar energy directly to electricity. In October 2009, only 600 megawatts of solar thermal power was operating all over the world. There are two major technologies for solar thermal utilization.

Solar energy can be divided into two categories: the sun and the sun. Solar thermal energy depends on the heating of the carrier fluid (usually water). The heated liquid can be used directly, such as by heating with hot water, or it can be used to promote other processes such as power generation. Solar cells or photovoltaic systems generate energy by capturing electrons excited by photons in sunlight. Electricity generated by solar power generation system can be used for many end uses. Photovoltaic (PV) cells utilize the electromagnetic nature of sunlight to generate electricity. The light striking the PV array emits electrons captured and oriented by the silicon structure of the PV cell. This flowing electron flow is electric and can be used to power any conventional appliance or motor. If all available roof spaces are used, rooftop solar power can supply half of the world's total energy demand.
