OFF-GRID SOLAR SOLUTION
In an off-grid solar system the electricity generated from the panels is transmitted from the Solar Inverter to the appliances at your home and also towards the battery . The energy stored in the battery is used during night. This runs independently from/off the power grid and hence does not require any permission from the electricity board. The cost of an off-grid solar system has an even wider range because there are a variety of sizes, applications, and components that impact the price. An alternative to off-grid solar systems is a hybrid system, which remains tied to the grid but includes a solar battery bank to store excess energy.
