What is the right angle for a solar panel? Is direction important while setting up solar panels?

 What time of year do you most need solar energy?

According to the study, the ideal angle or direction for installation is the home’s latitude from north to south, which determines the direction and angle of the solar panels, which are typically inclined at a 30-45-degree angle. The optimal tilt angle for a solar panel varies by projects and region

; however, in India, the south is the best direction.

It is also important to identify any areas that are concealed by shade.

This blog will address shadow issues on rooftops, examine the implications of the optimal tilt angle for solar panels, explain why solar panel angle and direction are critical in India, and assess the factors that affect

What are the best solar panel directions and angles in India?

India is in the northern hemisphere, so windows, doors, and walls facing south receive the most sunlight. Solar panels should be pointed south for the highest efficiency.

However, not all sections of the country get the exact same quantity of sunlight. Although facing south is usually the best orientation for solar panels, each site has an alternate solar panel angle.

For example, in the south, the best solar panel inclination angle is around 10 degrees, whereas in the north, it is preferable to use 20 degrees. However, the longitudinal location and latitude of the site will define the suitable tilt angle.

Factors That Affect Solar Panel Angle

The angle of your solar panels affects the amount of sunlight

For example, in the south, the optimal solar panel inclination angle is around 10 degrees, whereas in the north, it is more acceptable to use 20 degrees. Yet, the right tilt angle will be determined by the site’s longitudinal location and latitude. 

Factors That Affect Solar Panel Angle

The angle of your solar panels effects how much sunlight they can capture, and impacts the amount of energy generated. Here are the key elements affecting solar panel angle:

1. Geographic location.

Because northern India has a higher latitude, solar panels should be set at a steeper angle to capture the most sunlight, particularly during the winter. Southern India, on the other hand, requires a flatter tilt to maximize solar gain throughout the year due to its lower latitude.

2. Wind load.

Installing panels at a higher angle in high-wind areas may increase the chance of wind-related damage. This risk requires careful consideration of local weather patterns, as well as an effective mounting structure to ensure stability and durability.

3. Seasonal shifts.

To maximize efficiency year-round, line your tilt angle with the sun’s equatorial position. Any change in orientation can lead to an uneven output.t.

4. Shading issues.

Shadows cast by next objects, such as trees, buildings, or other structures, may decrease the effectiveness of your solar panels. To prevent shading issues, the angle and direction of the solar panels must be carefully studied.

The Effect of Angle on Solar Panel Efficiency.

A higher solar panel tilt angle in northern states could boost efficiency and power generation for the entire rooftop solar system, but there is a catch. Wind pressure on the panels increases with tilt angle due to increased winds in particular areas. 

The solution to this problem is using stronger mounting structures. While this may increase the final installation cost by approximately five percent, there is a 20% higher probability that you will not have a solid framework that can withstand strong winds and safeguard your investment.

Inadequate structural support can cause panels and structures to be damaged, uprooted, or destroyed during strong winds or storms. Repairs and replacements may wind up costing more than the electricity bill savings.

Why is the angle of a solar panel important?

The fundamental idea of solar panels is that photons in sunlight are transformed into energy by solar cells. When panels are placed perpendicular to the sun, they capture more solar energy and convert it to electricity.  Although optimal orientation increases photon absorption, seasonal variations may still affect performance.

Uncontrollable weather conditions might lower electricity generation even with the ideal panel angle. For instance, throughout the monsoon season The amount of electricity generated may decrease during cloudy seasons. Similar to this, clouds can lessen the quantity of sunlight that reaches the panels during the winter, particularly in places that are snow-covered.
