An off grid solar system provides electricity after a power outage or during the night hours since it includes battery storage and a backup. Solar panels, inverter, battery, and system balancing are among the four essential components. This solar system is more prevalent since it includes a backup power source and operates independently of the grid.
Solar panels, inverters, batteries, and system balancing are the four basic components of an off-grid solar system. In the presence of sunshine, solar panels create DC current that is stored in batteries. A charge controller is required to run DC (12V) applications such as fans and lights. You’ll need an inverter to convert DC voltage to AC voltage if you wish to use AC appliances (220V). All inverters nowadays function automatically, which means that the solar system’s electricity charges batteries and powers appliances immediately. In the event of a power outage, batteries also power appliances directly.
The following are the primary distinctions between an on-grid solar system and an off-grid solar system:
Off-grid solar systems are available in a variety of capacities for a variety of purposes, including small homes, 2-3 story homes, shops, offices, schools, warehouses, and more. Off-grid solar systems have a minimum range of 500W, an average range of 1kW, and a maximum range of 3kW, 5kW, 7.5kW, and 10kW. Simply put, a 1kW off grid Solar System using Single Battery (12V) costs around Rs. 80,000, whereas a 1kW Off Grid Solar System with Double Battery (24V) costs around Rs. 1,00,000. Any solar system’s price is determined by factors such as technology, brand, service, and warranty.
The amount of electricity you can run on an off-grid solar-powered system is determined by the power of the inverter and its efficiency. Most inverters have an efficiency of 80 percent, so if you buy a 3 kw inverter system, you can run up to 2,400 watts of maximum voltage at any given moment. A 3kW Solar System can successfully operate a 1.5 tonne inverter air conditioner and a 0.5 HP submersible pump.
In the long run, going off the grid makes financial sense.
Within 3-5 years, you may recover your solar panel investment. However, the investment in the battery systems which will be utilized to gather energy from the sun will need longer to pay off; battery system payback times typically run ten years.
