A solar photovoltaic (PV) rooftop system is, in essence, a miniature power plant that is located on your roof. In its most basic form, the Grid-interactive Rooftop Solar Photovoltaic (PV) System may be broken down into three primary parts. The solar photovoltaic modules, the mounting framework for the modules, and the inverter or power conditioning devices make up this system.
The solar photovoltaic modules that together make up an array need a mounting framework in order to be held at the correct angle and produce the maximum amount of power possible. Solar panels are responsible for converting solar energy in the form of light into direct current (DC) power (Direct Current).
The inverter and power conditioning device converts the DC electrical energy to AC (Alternating Current) electricity and then connects to the power grid through the AC distribution board. Through the metering panel that is linked to it, the output of the AC power may be monitored. The system’s 415 V AC output may be synced with the grid, and the system’s electricity can either be used locally or exported to the grid, depending on the amount of solar power generated and the amount of electricity consumed locally.
In India, the price of a solar panel with 1 kilowatt of capacity can range from around 45,000 to 50,000 rupees. However, the cost of this item might vary greatly from one location to another, as well as depending on the merchant serving a given region.
A solar power plant with a capacity of 1 kWp may produce between 4.5 and 5.5 units in a day when the weather is clear and bright.
In average, there must be ten square metres of shadow-free space for a one kilowatt rooftop system. However, the actual space needed could be different depending on the performance of the solar modules, where they are placed, and other factors.
If you have a solar system that is connected to the power grid at your home, then it will not function when the power goes out. However, if you have an off-grid solar system or a hybrid solar system, then it will function even if the power goes out, and you will be able to continue using your home’s appliances.
Rooftop solar is among the most secure investments since it provides excellent paybacks and has a payback time that ranges from three to five years.
