Solar product testing and certification
basic introduction
Solar products
Solar energy is one of the most environmentally friendly and easily
accessible energy sources in the 21st century. With global warming,
energy shortages and global concern for environmental protection,
the research on 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 progress and the introduction of policies by
various governments (for example, Germany promulgated the
"Renewable Energy Feed-in Tariff Law" as early as 2000 to support
the "whole-grid equalization"), the development of solar cells and
photovoltaic modules has been further accelerated. Rapid
development.
A solar power generation system is a device that directly converts
light energy into electrical energy through the photoelectric
effect or photovoltaic chemical effect. It consists of solar cells,
controller, battery (bank) and inverter (if the output power supply
is AC 220 V or 110 V).
Among them, solar panels are the core of solar power generation
systems. According to the different materials used, they can be
divided into: silicon solar cells (three types: monocrystalline
silicon solar cells, polycrystalline silicon thin film solar cells
and amorphous silicon thin film solar cells), multi- There are four
categories: compound thin film solar cells, polymer multi-layer
modified electrode solar cells, and nanocrystalline solar cells.
Silicon solar cells are the most widely used due to their early
development, relatively mature technology and high photoelectric
conversion rate. Multi-component thin-film solar cells have
developed rapidly in recent years due to their low material use,
small weight, smooth appearance, and easy installation, and have
great development potential.
It is worth noting that the solar power generation system will also
use batteries (packs), whose function is to store the electrical
energy released by the solar panels when there is light, and then
release it when needed. The batteries (packs) currently used are
generally lead-acid batteries, and there is no doubt that lithium
batteries will slowly replace lead-acid batteries.
