Solar Panel Tilt Angle in Indonesia
So far based on Solar PV Analysis of 87 locations in Indonesia, we've discovered that the ideal angle to tilt solar PV panels in Indonesia varies between 5° from the horizontal plane facing South in Banda Aceh and 10° from the horizontal plane facing North in Kupang.
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 Indonesia, the ideal angle to tilt your solar panels will vary by approx 15 degrees (between 5° from the horizontal plane facing South and 10° from the horizontal plane facing North).
Indonesia solar PV Stats as a country
Indonesia ranks 71st in the world for cumulative solar PV capacity, with 211 total MW's of solar PV installed. Each year Indonesia is generating 1 Watts from solar PV per capita (Indonesia ranks 88th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Indonesia?
Yes, there are several incentives for businesses wanting to install solar energy in Indonesia. The Indonesian government has implemented a number of policies and programs to encourage the adoption of renewable energy sources such as solar power. These include tax exemptions, subsidies, feed-in tariffs, and other financial incentives. Additionally, the government has established a Renewable Energy Fund which provides grants for research and development projects related to renewable energy technologies.
