In other words, within the next decade, grid parity of solar PV systems in China is forecasted to be achieved. This provides policymakers with the information to better plan the best time that cancels the subsidies and allows the market to determine the competitiveness of PV.
Although not all the PV projects are included in our dataset, the electricity generation of the projects in this dataset reaches 351.19 GWh, accounting for 53.1% of the total PV electricity generation in China; the installed capacity of these projects is 26.14 GW p, accounting for 33.8% of the total PV installed capacity in China.
The cost of solar PV electricity generation is affected by many local factors, making it a challenge to understand whether China has reached the threshold at which a grid-connected solar PV system supplies electricity to the end user at the same price as grid-supplied power or the price of desulfurized coal electricity, or even lower.
To reduce this financial gap and manage the decrease of PV costs, the Chinese government published the Notice on matters of PV power generation in 2018, which is referred to as the “531” policy, reducing the subsidies for PV from 0.36 CNY/kWh to 0.32 CNY/kWh.
To measure grid parity for the China case, we searched for the most optimal analysis method. The levelized cost of electricity (LCOE) is the most widely used indicator to measure the feasibility of PV grid parity; it is calculated as the total lifetime costs divided by the total lifetime electricity production [, , ].
According to the report of the International Energy Agency (IEA), by 2040, the electricity generated from PV systems in China will account for 13.2% in the stated policies scenario and 23.4% in the sustainable development scenario. As a result, PV will play a more important role in the future electricity system in China.

As the electricity in China is mainly provided by coal-fired power generation, supply-side grid parity suggests that the cost of PV systems should be competitive with the cost of coal-fired electricity. Here we used the coal-fired power generation electricity price as the benchmark when analyzing the supply-side grid parity. To analyze the grid ...

The efficiency (η PV) of a solar PV system, indicating the ratio of converted solar energy into electrical energy, can be calculated using equation [10]: (4) η P V = P max / P i n c where P max is the maximum power output of the solar panel and P inc is the incoming solar power. Efficiency can be influenced by factors like temperature, solar irradiance, and material …
For DGPV investors seeking to optimise long-term revenues and mitigate risks, and power users aiming to reduce electricity costs, amidst ongoing electricity market reforms, key questions remain: What is a TOU tariff and how has the pricing mechanism evolved?
