The angle between the rooftop ground and solar module, referred to as the angle for the solar panel, depends on your area’s latitude and graphical location. It is said that the solar panel will generate the maximum energy when the angle is near the value of the latitude. The installer should install the system at the best angle for solar panels.

Here is a small table mentioning the latitudes of different Indian states. It will give you an estimate for the best angle for solar panels:

States	Latitudes
Jammu and Kashmir, Uttarakhand, Himachal Pradesh, Punjab	30 – 36 degrees
Uttar Pradesh, Delhi, Bihar, Haryana, Rajasthan	24 – 30 degrees
Madhya Pradesh, Gujarat, West Bengal, Jharkhand, Chhattisgarh, Maharashtra, Odisha	18 – 24 degrees
Tamil Nadu, Andhra Pradesh, Karnataka, Kerala, Telangana	12 – 18 degrees

Along with the angle for solar panels, there are some other factors that you should keep in mind during the installation process so that you get the maximum energy output from the panels.
