The Correct Direction and Angle for Installing Solar Panels in India—The Secret to Maximum Energy Production

Today, on behalf of Chemitech Group, we'll talk about a topic every solar panel installer should know: solar panel direction and tilt angle.

If you purchase a high-quality panel but install it in the wrong direction or angle, power production could be reduced by 20% to 40%. Therefore, it's important to know the best solar panel direction and angle for installation in India.

South – The Most Suitable Direction

In India, the sun travels from east to west, and the south-facing side receive the most sunlight.

Therefore, based on our years of experience, it's best to install solar panels facing south. This direction allows the panels to receive direct sunlight throughout the day, maximizing energy production.

If your roof doesn't face south, panels can also be installed facing east or west.

However, production in these directions may be reduced by approximately 10–15%.
North-facing panels are not recommended as they receive very little direct sunlight, which can reduce production by approximately 25–30%.

The Importance of Tilt Angle

Along with direction, panel tilt is also very important. India is a tropical country where the sun is high throughout the year, so the correct tilt varies from city to city.
Choosing the right angle for your city can make a significant difference in power production.

*Delhi / Jaipur: 28°–30°
*Ahmedabad / Mumbai: 20°–23°
*Chennai / Hyderabad: 12°–15°
*Bangalore: 10°–13°
*Lucknow / Patna: 25°–28°

If your panel is shaded by a tree, wall, or other object, production will be significantly reduced. Therefore, ensure that the panel is free of shadows between 9 a.m. and 4 p.m.—this is the peak power generation time.

Choosing the Right Mounting System

If your roof doesn't face south, don't worry.

You can use an adjustable mount system, which allows you to position the panel at the correct direction and angle.

Another option is a ground-mount system, which is useful for those who don't have a sufficiently large roof or have an inconvenient orientation.

Choosing a Quality Brand

As important as direction and angle are, it's equally important to choose high-quality solar panels.
For example, the Adani Solar Panel are known for their durable quality and high efficiency.
We've seen Adani Solar Panels perform exceptionally well in many successful installations.

Conclusion

If you want your solar panels to generate maximum power, be sure to install them facing south and at the correct tilt angle for your city.
