At the beginning of the definition of new energy in 1980, new energy technology and new energy industry have developed rapidly. As a new renewable energy technology, solar power generation has been industrialized. The most important component - Solar panels, the scale of the industry is also expanding rapidly. The voltage of the panel system has reached 1500V DC. Therefore, its safety and efficiency testing is becoming more and more important. The safety regulations related to solar energy are constantly proposed to amend and define.
