Below is the average daily output per kW of Solar PV installed for each season, along with the ideal solar panel tilt angles calculated for various locations in China. Click on any location for more detailed information.

Explore the solar photovoltaic (PV) potential across 168 locations in China, from Jiamusi to Sanya. We have utilized empirical solar and meteorological data obtained from NASA's POWER API to determine solar PV potential and identify the optimal panel tilt angles for these locations.

Feel free to contact us if you wish for us to include a general Solar PV Analysis for a certain city or location not already listed here for China. We will be more than happy to manually add it for you.

Solar Panel Tilt Angle in China

So far based on Solar PV Analysis of 168 locations in China, we've discovered that the ideal angle to tilt solar PV panels in China varies between 42° from the horizontal plane facing South in Jiamusi and 16° from the horizontal plane facing South in Sanya.

These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).

Depending on where you are based in China, the ideal angle to tilt your solar panels will vary by approx 26 degrees (between 42° from the horizontal plane facing South and 16° from the horizontal plane facing South).

China solar PV Stats as a country

China ranks 1st in the world for cumulative solar PV capacity, with 306,973 total MW's of solar PV installed. This means that 6.20% of China's total energy as a country comes from solar PV (that's 13th in the world). Each year China is generating 217 Watts from solar PV per capita (China ranks 24th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in China?

Yes, there are several incentives for businesses wanting to install solar energy in China. These include subsidies from the Chinese government, preferential tax policies, and access to low-interest loans. Additionally, businesses may be eligible for renewable energy certificates (RECs) which can be sold on the open market for additional income.
