    basic introduction

    Solar energy is one of the most environmentally friendly and easily accessible energy sources in the 21st century. Along with global warming, energy shortage and global concern for environmental protection, the research of solar cells and the development of the entire photovoltaic industry have received attention and support from various countries. The entire photovoltaic industry has entered a period of rapid development since the 1990s. In recent years, due to technological advancement and the introduction of policies by governments of various countries (such as Germany promulgating the "Renewable Energy On-grid Electricity Price Law" supporting the "full-network flat" as early as 2000), the speed of solar cells and photovoltaic modules has been further accelerated Rapid development.

    Solar power generation system is a device that directly converts light energy into electrical energy through photoelectric effect or photovoltaic chemical effect. It is composed of solar cell, controller, battery (group) and inverter (if the output power is 220 V or 110 V).

    Among them, the solar panel is the core of the solar power generation system. According to the different materials used, it can be divided into: silicon solar cells (three types of monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells), multiple There are four categories of compound thin film solar cells, polymer multilayer modified electrode type solar cells, and nanocrystalline solar cells. Silicon solar cells are the most widely used because of their early development, relatively mature technology, and high photoelectric conversion rate. The multi-component thin-film solar cell has rapid development momentum in recent years due to less materials, small weight, smooth appearance and convenient installation, and has great development potential.

    It is worth noting that batteries (groups) will also be used in the solar power generation system. Its function is to store the electrical energy released by the solar panels when there is light, and then release it when needed. The batteries (groups) currently used are generally lead-acid batteries. There is no doubt that lithium batteries will slowly replace lead-acid batteries.

    Solar product testing and certification
