Solar Rooftop system is one of the best ways to utilize solar energy for home use. It today needs to use nonconventional or sustainable sources of clean energy.
A solar photovoltaic (PV) system mounted on a rooftop of a building is a mini-power requirement or feed into the grid. Although anyone can install a solar rooftop system, the size of the installation varies significantly depending on the availability of space, amount of electricity consumed by the property and the ability or willingness of the owner to invest the capital required.
Solar rooftop, which is often called a rooftop Photo-Voltaic power station or PV system, is a photo-voltaic system that has its electric generating solar rooftop panels mounted on the rooftop of residential or commercial buildings or structures. Solar rooftop systems on residential buildings typically feature a capacity of about 5-20 KW, and in cases of those solar rooftop panels mounted on commercial buildings, often reach 100KW or more.
Types of Solar Rooftops : There are three kinds of solar rooftop systems that can be considered:
On-grid Solar Rooftop System: This on-grid solar rooftop system is integrated with the main grid supply. This most straightforward kind of solar rooftop only integrates with grid power and has no other back-up power sources. This is known as an on-grid solar rooftop system because this solar rooftop system is always in sync with the grid. This on-grid solar rooftop is recommended for those organizations which have a guaranteed supply of on-grid power. Because if you suffer from frequent power interruption as such, a plant won’t work if the grid doesn’t work. This solar rooftop system allows power to be used from the grid supply only when the solar rooftop system is unable to supply the required power. Thus eventually, the solar rooftop saves the expenses of non-stop grid power. And this solar rooftop system can earn revenues as any excess electricity generated gets accumulated in the grid for future purposes.
Off-grid Solar Rooftop System: This kind of solar rooftop system is not integrated with any grid power; instead, this solar rooftop system only integrates with batteries or diesel generators. The electricity generates from the solar rooftop panels charges the battery, which can be used to power various applications later. This kind of solar rooftop system is recommended in such locations that are not connected to the grid at all. This type of solar rooftop is perfect for small loads.
Hybrid Solar Rooftop System: This kind of solar rooftop system can be integrated with both grid power, batteries, and diesel generators. The main advantage is if the battery gets charged by the electricity that generates from the solar rooftop system, the excess power accumulates in the grid as revenues. Hybrid solar rooftop systems are recommended for those energy consumers who have grid power but with frequent interruptions and who need critical loads to be powered continuously. Most industrial and commercial consumers in India fall under this hybrid solar rooftop system.
Net Metering: Net metering, which is also known as the billing system, credits the owner of the solar rooftop system’s owner for feeding the excess energy to the grid. For example, if a house has a solar rooftop system or a PV system that has the ability to generate more electricity than the home uses during daylight hours. If the house is net-metered, then the electricity meter would run backward to provide the house owner with the credits.
