With growing environmental concerns, the use of solar energy is increasing rapidly. India continues to make tremendous progress in increasing its solar power generation capacity. This renewable energy source is widely being adopted in commercial, residential and industrial sectors. Solar energy can be harnessed through rooftop solar installations. Installing solar panels can be beneficial as it helps generate electricity at an affordable cost.
How do solar panels work?
A solar panel is a board comprising an assembly of solar cells (photovoltaic cells). The system includes an inverter, AC/DC switches and electrical conduit. When sun rays fall on the panel, solar energy is converted into electrical energy.
Can you install solar panels in your apartment?
If you own an apartment, you can go for solar panel installation on the rooftop. Those who reside in a rental property can also utilise the benefits of solar energy by opting for a portable solar panel system. It can be easily installed on a balcony or any outdoor space.
Is any permission required to install solar panels at home?
In case the terrace of your building is a shared asset among all the flat owners, you may have to seek permission from the housing society before installing the solar panel system.
You will require approval from your electricity provider and the local municipal authority to install a solar on-grid system. If you install solar panels at a 10-foot height, permission from the municipality is required.
Things to consider before solar panel installation
Suitable roof conditions
Solar panels come with a lifespan of around 25 to 30 years. However, the solar panels’ performance also depends on the condition of the roof. If the roof is old or damaged, they may not serve their full-service life. Make sure to repair the roof before installing the system.
Consider the availability of space
There should be ample space available for the rooftop solar panel. Typically, apartments have limited roof space. So, you can opt for smaller solar panels or utilise shared rooftop facilities. Select an area that receives maximum sunlight. In India, the ideal direction to set up solar panels is the south direction, as sunlight is available most of the time.
Assess the energy requirements
Every building has its specific energy requirement. Estimate the energy needs of your building before installing a solar panel. A solar panel comprises 36 to 72 PV cells. Each cell generates about 0.5 V.
Installation cost
Solar panel installation costs may range from Rs 40,000 to Rs 6,00,000. It can cost higher for larger installations. Mid-range solar panels are suited for residential purposes. Installing rooftop solar panels may involve some upfront expenses. However, it will save electricity bills in the long run.
FAQs
Do solar panels work on a rainy day?
Solar panels function even when the sunlight is partially blocked due to the presence of clouds. However, their energy production capacity will reduce.
Does moonlight help solar panels?
Solar PV panels can provide electricity at night from the stored energy. However, they cannot draw power in the moonlight.
Do solar panels need cleaning?
It is essential to ensure that dirt does not build up on solar panels. Regular cleaning of solar panels ensures optimum performance.
Do solar panels need maintenance?
Solar panels do not require maintenance. However, make sure to clean them regularly and do not allow any obstacles that might block sunlight.
