Solar Panel Tilt Angle in Nepal
So far based on Solar PV Analysis of 22 locations in Nepal, we've discovered that the ideal angle to tilt solar PV panels in Nepal varies between 27° from the horizontal plane facing South in Surkhet and 25° from the horizontal plane facing South in Biratnagar.
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 Nepal, the ideal angle to tilt your solar panels will vary by approx 2 degrees (between 27° from the horizontal plane facing South and 25° from the horizontal plane facing South).
Nepal solar PV Stats as a country
Nepal ranks 89th in the world for cumulative solar PV capacity, with 93 total MW's of solar PV installed. This means that 0.10% of Nepal's total energy as a country comes from solar PV (that's 43rd in the world). Each year Nepal is generating 3 Watts from solar PV per capita (Nepal ranks 86th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Nepal?
Yes, there are incentives for businesses wanting to install solar energy in Nepal. The Government of Nepal has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that install solar systems. Additionally, the government has established a Renewable Energy Fund which provides grants to support research and development activities related to renewable energy technologies.
