Description

Control and Monitoring Device of Solar tracking Power generation complex}

The present invention relates to a solar tracking generator control and monitoring device with improved land use rate and power generation efficiency.

Solar power generation is a power generation method that uses sunlight and converts solar energy into electric energy. It is based on the photoelectric effect, and in the photoelectric effect, light has energy and can be converted into electrical energy when photons hit a specific substance. Therefore, solar power generation uses a battery module that responds to sunlight, that is, a sunlight cell. Therefore, it is different from solar power generation, which uses heat energy as it is or heats water stored in solar heat to run a turbine with it.

As of the end of 2015, the highest efficiency is about 50-52%. Compared to other power generation methods, the high-efficiency method is expensive to manufacture. Commercial cells or modules are about 15-22%, and low-cost mass-produced products are lower than that. Directly used home and residential use can be neglected, but if it is produced and transmitted far from the city center, there may be an additional 5-10% reduction in efficiency in storage or transmission. However, since solar energy itself is completely free, it is a good power generation method if only the land price or area problem is solved.

In addition, high efficiency can be achieved by stacking several cells like a tandem structure. However, due to the high manufacturing cost, high-efficiency panels have many special purposes where efficiency is more important than price. It is made of special materials that are not common materials like silicon.

On the other hand, in general, solar power generation systems (PV) are actively researched and developed in advanced countries as a measure against global environmental problems and diversification of future energy sources thanks to the non-pollution and infinity of solar energy. It is in the spotlight as a future industry around the world. In particular, as fossil fuels have been reduced through the Convention on Climate Change, the market demand has inevitably increased and continues to grow exponentially in line with the initial industrial growth curve.

In particular, Korea needs to develop alternative energy because of lack of resources. In particular, it is necessary to develop eco-friendly energy to prevent environmental pollution, and solar power generation with high land use rate and power generation efficiency is required.
