Highlights of Blog – The tilt should be equal to your latitude, plus 15 degrees in winter, or minus 15 degrees in summer for Best Direction for Solar Panels to Face in India. If the Solar panel mounting has a tilt that can be adjusted seasonally the solar panel will receive 10% (in winter) to 40% (in summer) more energy than fixed panels.
When anyone is thinking about installing solar panels, one of the most valid question to ask is how exactly can we decide towards which direction our panel is supposed to be placed. The answer to this question varies from country to country. The straight answer to this is the question for India is in South Direction.
Why Should Solar Panels in India be South-Facing?
Our country India lies in the southern hemisphere so when the sun travels, it takes an elliptical trajectory going from east to west having an inclination towards the south, hence to get the maximum quantity of solar energy we have to place our panel accordingly. As you can see, be it summer or winter, the inclination is towards the south.
After the direction, the other important parameter is the tilt angle.
What should be angle of solar panels in India?
The tilt angle is determined according to the latitude of your position. For example if you are living in Cochin-Kerala, the tilt angle for your solar panel will be approx. 10-12 degree. On the other hand if you want to incorporate a panel in Delhi, your tilt angle will be almost 28- 30 degree.
Before incorporating a panel, we need to ensure that there is no tall obstacle coming in between the sun rays and the panel as the shadow of the obstacle will fall on the panel and will disintegrate its efficiency So the next time you think of installing a solar panel, take out your personal gizmo and check your orientation with respect to the direction and enjoy the benefits of free energy – The Solar Energy.
To get the maximum efficiency from solar panels, you need to point them in the direction that captures the most sun. But there are a number of variables in figuring out the best direction. This page is designed to help you find the best placement for your solar panels in your situation in India.
This advice applies to any type of panel that gets energy from the sun via photovoltaic panels. We assume that the panel is fixed, or has a tilt that can be adjusted seasonally. (Panels that track the movement of the sun throughout the day can receive 10% (in winter) to 40% (in summer) more energy than fixed panels.
Solar panels should always face true south as India is located in the northern hemisphere. True north is not the same as magnetic north. If you are using a compass to orient your panels, you need to correct for the difference, which varies from place to place. Search the web for “magnetic declination” to find the correction for your location.
The next question is, at what angle from horizontal should the panels be tilted? Books and articles on solar energy often give the advice that the tilt should be equal to your latitude, plus 15 degrees in winter, or minus 15 degrees in summer. It turns out that you can do better than this – about 4% better.
ANP Solar in the near future will be bringing a fully automated solar panel system which will sync with the movement of the sun and hence will ensure maximum grabbing of solar packets by your panels. Can’t wait for this to come, right?
