Solar Panel Tilt Angle in South Korea

So far based on Solar PV Analysis of 119 locations in South Korea, we've discovered that the ideal angle to tilt solar PV panels in South Korea varies between 34° from the horizontal plane facing South in Sokcho and 29° from the horizontal plane facing South in Seogwipo.

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 South Korea, the ideal angle to tilt your solar panels will vary by approx 5 degrees (between 34° from the horizontal plane facing South and 29° from the horizontal plane facing South).

South Korea solar PV Stats as a country

South Korea ranks 8th in the world for cumulative solar PV capacity, with 18,161 total MW's of solar PV installed. This means that 3.80% of South Korea's total energy as a country comes from solar PV (that's 21st in the world). Each year South Korea is generating 350 Watts from solar PV per capita (South Korea ranks 9th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in South Korea?

Yes, there are incentives for businesses wanting to install solar energy in South Korea. The Korean government offers a variety of financial incentives and subsidies for businesses that install solar energy systems. These include tax credits, grants, loans, and other forms of support. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make the installation of solar energy systems more attractive to businesses by providing them with a guaranteed return on their investment.
