An essential investment that will power your house for many years is a rooftop solar system. Many people think that installing solar panels on steel or aluminum rods will keep your home electrified for many years. In actuality, though, every rooftop solar system is the result of careful engineering. In order to maximize the output of power generation, every single component—from the mounting structure to the inverter, connecting cables, panel brand, and the direction and solar panel angle —is essential.
Make sure your solar panels are orientated perpendicular to the sun during peak hours to maximize electricity production and further reduce costs for saving money . The latitude of the home from north to south determines the direction and angle of the solar panels in nations like the USA, where they are frequently inclined at an angle of 30 to 45 degrees. Though the recommended tilt angle of the solar panel varies on your project and region, true south is the best orientation for solar panels in India.
It’s also critical to detect any regions that are covered by shadows.
The optimal tilt angle for solar panels will be disclosed in this blog, along with its consequences, the reasons why solar panel angle and direction are important in India, how to cope with rooftop shadows, and the variables that influence panel angle.
Which direction and angle are best for solar panels in India?
South-facing windows, doors, and walls receive the most sunshine because India is in the northern hemisphere. For optimal efficiency, solar panels should be orientated southward.
However, not all parts of the nation receive the same amount of sunlight. Although facing south is the standard orientation for solar panels, each site has a different angle.
For instance, in southern states, the ideal solar panel inclination angle is about 10 degrees, whereas in northern states, it is more appropriate to use 20 degrees. However, the latitude and longitudinal location of the site will determine the ideal tilt angle.
Elements That Impact the Angle of a Solar Panel
Your solar panels’ angle directly affects how much electricity they can generate by determining how much sunlight they can capture. The following are the main variables that affect solar panel angle:
1. Location
Due to the higher latitude of India’s northern regions, solar panels are best orientated at a steeper angle to maximize sunlight, particularly in the winter. Southern India, on the other hand, needs a flatter tilt to maximise solar gain all year round due to its lower latitude.
2. Load from Wind
Installing panels at a greater angle can raise the chance of wind load damage in regions that are prone to strong winds. Because of this risk, local weather patterns must be carefully considered, and a sturdy mounting structure is needed to guarantee stability and longevity.
3. Variations by Season
Align your tilt angle with the sun’s equatorial position for year-round maximum efficiency. Any shift in focus could lead to an output that is unbalanced.
4. Problems with Shading
Your solar panels’ efficiency may be decreased by shadows cast by nearby objects like trees, buildings, or other structures. To reduce shading problems, the angle and direction of the solar panel should be carefully considered.
Tilt Angle's Impact on Solar Panel Efficiency
There is a catch: in northern states, a higher tilt angle for the solar panels will boost the overall efficiency and power generation of the rooftop solar system. Because of the increased wind speeds in certain areas, the tilt angle increases the wind pressure on the panels.
Stronger mounting structures are the answer to this issue. The risk of not having a sturdy structure that can endure severe winds and safeguard your investment rises by 20%, even though the overall installation cost may go up by roughly 5%.
During strong winds or cyclones, panels and structures may be damaged, uprooted, or destroyed due to inadequate structural support. 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 underlying solar panels is that photons in sunlight are converted into energy by solar cells. Panels capture more solar energy and transform it into electricity when positioned perpendicular to the sun. Although optimal orientation increases photon absorption, seasonal variations can still affect performance.
Even with the ideal panel angle, certain uncontrollable weather circumstances can lower the amount of electricity generated. For instance, electricity generation may decrease when the sky is cloudy during the monsoon season. Similar to this, clouds can lessen the quantity of sunlight that reaches the panels throughout the winter, particularly in places that are snow-covered.
Addressing Shadow Issues on the Rooftop
Imagine putting your solar panels on your roof at the proper angle and orientation, only to discover that they are shaded by trees or other obstacles. Your vendor should inspect your rooftop before installing solar panels to find any possible shadow spots over a 12-year period so that the system may be designed appropriately.
Keep in mind that each kilowatt requires roughly 100 square feet of space free from shadows. To find the best solution if you have limited rooftop space and shadow difficulties, it’s best to speak with a solar expert.
Choose Right Solar with the Corret Solar Panel Angle
Now that you know how important solar panel direction and angle are, you need to ask your solar vendor what the ideal rooftop solar angle is.
As was previously said, a lot of solar sellers consider installing solar panels on rooftops to be a straightforward masonry task that can be finished by regular workers. But the engineering is far more complex.
Steps:
1. Analysis of Shadows
After you schedule a consultation, one of our solar specialists will inspect your rooftop to find any possible shadow spots and calculate how much space is accessible without any shadows. Using our sophisticated equipment, we also determine if your house faces north or south.
2. Put in place sturdy mounting frameworks
Given how frequently storms occur in India, we created WindPro MountTM, the strongest and safest rooftop solar structure that can resist winds of up to 180 kmph. This ensures that your investment is safe even during the most severe storms by reducing the safety risks brought on by shoddy and inadequately fitted solar systems.
