Solar energy is a rapidly growing form of energy, and the solar energy market has also made considerable progress in the past decade. According to data, the global solar energy market has a compound annual growth rate of 47.4% based on the annual average solar system installed capacity.

In some major countries in the world, especially China, Germany, Italy, Spain, the United States, France, and South Korea, the federal government, state governments, and local government agencies have used tax rebates, tax credits, and other incentives to purchase solar products. End users, distributors, system integrators, and manufacturers provide subsidies and economic incentives to promote the use of solar energy in grid-connected and off-grid applications and reduce dependence on other energy sources.

But generally speaking, due to the political and economic instability in many oil and gas producing regions around the world, governments of many countries are taking active measures to reduce their dependence on foreign energy. Solar energy provides a very attractive power generation program and does not form a serious dependence on foreign energy.

At present, the solar power generation system has formed an industrialized application. It has the characteristics of modularization of battery components, convenient installation and maintenance, and flexible use. It is the most widely used technology for solar power generation.
