The flow of electricity results from the characteristics of the semiconductors and is powered entirely by light striking the cell. Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. As the details evolve, two cornerstones have emerged. On this page you'll find resources to learn what solar energy is; how you, your business, or your community can go solar; and find resources for every step of the way. Solar. . Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. You can join them to illuminate the future of energy.

In 2018, solar power accounted for roughly 3 percent of China's electricity generation and 9 percent of China's power capacity. China is the largest market in the world for both photovoltaics (PV) and solar thermal energy. Its PV capacity crossed 1,000 gigawatt (one terawatt, 1 TW) in May 2025. [1]. . The Chinese solar industry is at a pivotal point. Rapid solar capacity expansion overwhelms the grid, PV manufacturers compete for market shares, and then large target markets slap import tariffs on Chinese PV products, taking off their competitive edge. China's National Energy Administration (NEA) released its 2025 power sector statistics on Jan. Here's a comparison of the main types: China's leadership in solar power is attributed to several key factors: Government Policy and Support: The Chinese government has implemented aggressive policies. . As of 2024, China was responsible for 64 percent of the world's utility-scale solar and wind construction, with 339 gigawatt hours of renewable energy infrastructure in the works, even though it only has around 17 percent of the planet's population. To put that in perspective, at that point the. .
