China installed a record 315 GW (AC) of new solar capacity in 2025, lifting cumulative installed PV capacity to 1. 2 TW and pushing non-fossil power sources past thermal generation for the first time. China's National Energy Administration (NEA) released its 2025 power sector statistics on Jan. 28. . Last year, a viral drone video from China's Guizhou province revealed an entire mountain range blanketed in solar panels stretching to the horizon. 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. It is published annually as a March special issue of the China Energy Policy Newsletter.

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines.

What is grid parity in solar energy?
In the context of solar energy, grid parity refers to the point at which the cost of generating electricity from solar panels is equal to or lower than the cost of electricity from the grid.
How has grid parity impacted the solar industry?
Grid parity has also led to increased competition in the solar industry, driving down prices and encouraging companies to innovate and improve their products. This competition has resulted in more efficient solar panels, improved energy storage solutions, and advancements in solar technology.
Can solar PV be a stand-alone replacement for conventional generation?
With current technology solar PV generation cannot operate as a stand-alone per-megawatt replacement for conventional generation methods. Grid parity will be reached for small grid level generation independently from utilities scale generation.
Is solar PV cost-competitive?
In some locations, PV has reached grid parity, the cost at which it is competitive with coal or gas-fired generation. More generally, it is now evident that, given a carbon price of $50/ton, which would raise the price of coal-fired power by 5c/kWh, solar PV will be cost-competitive in most locations.
