One or two layers of a semi-conductive substance, typically silicon, make up a photovoltaic cell. An electric field is created across the layers of the cell by light, and this leads to the flow of electricity. The amount of electricity flowing in a given direction increases with light intensity.

Zillow found that the average gain in a home’s appraised value due to solar panels was 4.1%. The strength of the local solar market in your area and your location determine these values.

During a blackout, solar panels won’t be able to supply electricity to your house or place of business. There are two caveats to this rule, though: either your system has energy storage built in, or you choose an off-grid system instead of grid-tied solar to avoid the advantages.

When contemplating the installation of solar systems in their houses, many often consider the upkeep that comes with it. However, the truth is that solar systems require little upkeep. You won’t need to worry about repairs for many years as long as your system is installed and maintained correctly.

Examining your power bill is the first thing you should do before beginning the solar panel installation procedure. You may estimate your monthly use in kWh by glancing at your electricity bill.

Typically, two kinds of permission are needed for an on-grid solar system.

• Authorization from your power supplier:

There are various licences you must obtain before exporting electricity into the grid since under a grid-tied system, you will always be connected to your current electricity supplier and able to import and export electricity as needed.

• Net Metering Application: When you install a solar on-grid system, the one-way meter you now have will be swapped out for a two-way or bi-directional meter. A net metering application typically costs between Rs. 500 and Rs. 2000.
• Net Metering Agreement: In addition to your net metering application, you must submit a net metering agreement. This basically notifies your electricity provider that you are installing solar power and that you plan to export any excess energy it produces to the utility grid and pull any excess electricity you need from the same grid when it is not in use.

• Your municipality’s permission: The following are the cases:

Installation of solar panels on a direct roof: You do not require municipal permission to install solar panels on top of an asbestos or metal roof that you currently own.

Solar panels installed on a terrace (RCC): Depending on the height of the installation, you will need authorization to install solar panels on your terrace.

For No Height: You won’t require authorization if your solar panels are mounted at a modest height—usually less than six feet.

Elevated solar panels: In the event that you install solar panels at a height of ten feet, you may need to notify your municipality or obtain authorization in certain situations. (Verify with your local government)

Solar panels installed on a metal roof atop your terrace: If your terrace already has a metal roof that was built with permission, you are able to add solar panels to the roof. However, you might need approval from your town if you want to build a new metal shed and put solar panels on top of it so you can use the space underneath it. (This authorization varies depending on the location.)

1. How can I tell if solar panels are a good fit for my house?

Per kW, solar panels need an area of 100 square feet. For a 2 to 3 kW solar panel installation, a typical Indian home with a monthly electricity cost of Rs. 2000 will need 200 to 300 square feet. This space needs to be shadow-free all day, every day of the year.
