Accurate Solar Panel Direction And Angle In India – Complete Details
Hello all! Today we want to inform you about an important topic. We get this question frequently. IIt's: What is the correct solar panel direction and angle in India to install solar panels?
In These days, the number of solar panel installations is rapidly increasing across India.
High electricity bills are taking a toll on people's pockets. People are worried about rising electricity bills. In such a situation, solar panels have proven to be a boon for them. There are many businesses where electricity bills are equal to or close to their production.
In such a situation, running a business becomes very difficult. Solar panels have provided a good opportunity for such businesses to grow. Now, most people want to get electricity from solar panels.
But this is only possible if solar panels are installed correctly. Have you ever considered: "How much can electricity production decrease if panels are not installed in the correct direction or angle?"
Yes! You read this correctly.
This is also an important factor. For adequate power generation, proper solar panel direction and angle are crucial. Failure to do so can reduce power production by 20% to 40%.
As the best solar panel distributor in Noida, we want to tell you about the best direction and angle for installing solar panels in India.
What is the correct direction for installing solar panels in India?
We all know that sunlight is essential for solar panels to generate electricity. But do you know which direction in India receives the most sunlight?
Let's explain.
In India, the sun moves from east to west. Therefore, the south direction is considered the preferred direction for optimal power generation from solar panels.
Installing panels in this direction ensures the panels receive maximum sunlight, resulting in increased power generation.
Many times, the roof of our house doesn't face south, but there's nothing to worry about. You can consider these tips:
- You can also install it facing east or west. These directions will not produce as much electricity, but they won't be less either. These directions will produce 10-15% less electricity.
- North-facing installation is not ideal at all, as it receives very little direct sunlight. This can reduce production by approximately 25%-30%.
What is the ideal tilt angle for solar panels?
Tilt angle is just as important as solar panel orientation for maximizing electricity production. This means that panel orientation is based on your city's latitude. India is located in a tropical region, where the sun's position remains relatively high throughout the year.
Here are our team's ideal tilt angles for some major Indian cities based on latitude.
Ideal Tilt Angle
- Delhi / Jaipur = 28°–30°
- Ahmedabad / Mumbai = 20°–23°
- Chennai / Hyderabad = 12°–15°
- Bengaluru = 10°–13°
- Lucknow / Patna = 25°–28°
Tip: Always use solar panel direction and angle based on your city's latitude. This will maximize electricity production year-round.
Avoiding shade is important.
We all know that solar panels generate electricity from sunlight. Therefore, positioning the panels correctly is crucial.
It's important to note that if a tree, wall, or tank casts a shadow on the panel at any time, it will affect the power output of the entire system.
Necessary precautions to avoid shadows
- The panel should receive uninterrupted sunlight throughout the day.
- Shadows interfere with your power output, so if necessary, install the panel frame at a higher location to avoid shadows.
What if your roof isn't facing south?
This is a real question many people face.
In India, most houses have east-west or north-south roofs. So, what should you do if your roof isn't facing south?
So, you shouldn't worry about this. Solar panel manufacturers in India have already considered this and have provided some tips for this.
1. Adjustable Mounts:
Solar panel companies offer adjustable mounts to address this issue. These allow panels to be mounted at the correct angle and tilt. These frames are made of metal and can be permanently installed.2. Ground-Mount Systems:
If rooftop space is limited or the orientation is not suitable, you can also use the ground for correct solar panel direction and angle.
As one of the best solar panel suppliers in Noida, we recommend that you have your roof analyzed first. This will help the company install your panels in the correct direction.
What's the difference between the correct direction and angle?
We all know that to generate maximum power, panels must be in the correct direction and tilt. But the question is, if we install panels in the wrong direction, will we
not get any electricity?
The answer to your question is that we will get electricity. But the correct direction and tilt produces maximum power.
The wrong direction can lead to lower power. Here are some comparisons to help you understand the correct direction and angle.
- Direction: Estimated Power Generation Loss (%)
- South (South) 100% -
- East (East) Approximately 85-90% 10-15%
- West (West) Approximately 85-90% 10-15%
- North (North) Approximately 70-75% 25-30%
Let's take a simple example
Suppose you invest ₹2 lakh in a solar panel and install it in the wrong direction. You could lose approximately ₹50,000 to ₹60,000 per year.
Choosing the right solar panel is equally important.
It's not necessary that installing a solar panel in the right direction and at the right angle will ensure adequate electricity production throughout the year.
Often,
we end up installing the wrong brand or substandard panels in pursuit of cheapness. This results in insufficient electricity and ruins our investment. Therefore, we should only
purchase solar panels from a trusted brand.
The advantage of purchasing a panel from a reputable company is that they provide a guarantee and maintenance. In India, Adani Solar Panel
manufactured by Adani Group in India offer excellent performance and are of excellent quality. With just one investment, you can expect years of hassle-free electricity production.
Therefore, you should purchase the right brand of solar panel from a solar panel distributor.
Tips for Choosing the Correct Solar Panel Direction and angle in India
Here are some of our suggestions.By following these tips, you can choose the best solar panel direction and angle for Indian conditions.
- Always choose south direction as the first for installing solar panels.
- Keep the inclination consistent with your city's latitude.
- It is very important to ensure that the panels are not shaded, especially when the sun is shining. The hours between 9 am and 4 pm are considered the most suitable for solar energy.
- The mounting structure of the solar panel should always be strong and rust-resistant.
- Always have the solar panel plate installed by a reputable solar panel distributor.
Our Final Words.
From the information above, you should know that the south direction is considered the most suitable solar panel orientation for installation in India. A 30° inclination is ideal.
So, if you're installing solar panels for your business or even for domestic use, you should first consider the south direction.
If the south direction isn't possible, you can also use adjustable mounts or ground installation. If this isn't possible, you can have your roof analyzed by a solar panel distributor or company.
Chemitech Group is also a solar panel distributor, having installed over 5,000 solar panels in India. We also analyze our customers' roofs and then apply the right solar panel direction and angle for installation. This ensures our customers have adequate electricity throughout the year.
Remember—the combination of the right direction, the right inclination, and the right brand provides maximum benefits from solar energy.
