Solar tracking solar power generation system and method thereof

The present invention relates to a solar power generation system, and more particularly to a solar tracking type solar power generation system.

Solar power is an emerging renewable energy source. Solar energy is abundant, no transportation is required, and environmental pollution is low. Solar energy has created a new form of life for human beings, enabling society and humanity to enter an era of energy conservation and pollution reduction.

Solar energy refers to the use of solar radiation primarily for practical purposes. However, in addition to geothermal energy and tidal energy, all other renewable energy sources are derived from the sun's energy. Solar technology is widely defined as a passive or active way to capture, convert and distribute sunlight. Active solar technology uses solar panels, pumps, and fans to convert sunlight into useful output. Passive solar technology includes the selection of materials with good thermal properties, design, natural air circulation, and the location of the building in accordance with the sun. Active solar technology, which increases energy supply, is considered a supply-side technology; passive solar technology, which reduces the need for alternative resources, is often considered a demand-side technology.

Solar technology is divided into active (active) and passive (passive). Examples of active sources are solar photovoltaic and photothermal conversion, using electricity or mechanical equipment for solar energy collection, and these devices operate on external energy sources and are therefore called active. Examples of passives include the introduction of sunlight into buildings, etc., in which the use of buildings is designed and the materials used are selected to achieve the purpose of using solar energy.
