On-Grid (Grid-Tied): The most common and cost-effective system. It connects to the utility grid. Excess power generated is sent to the grid (earning you credits via Net Metering). However, it does not work during a power cut for safety reasons.
Off-Grid: Completely independent of the utility grid. It uses batteries to store energy for use at night or during power cuts. It is more expensive due to battery costs.
Hybrid: The best of both worlds. It connects to the grid and has battery backup. It works during power cuts and allows for net metering.
A: This is a central government scheme aimed at providing free electricity to households. Under this scheme, subsidies are provided directly to the customer's bank account for installing rooftop solar. It significantly reduces the upfront cost of installation.
A: Net Metering is a billing mechanism. When your panels produce more electricity than you are using, the surplus is exported to the grid. The electricity board gives you "credits" for this export. At night, when you pull power from the grid, these credits are adjusted against your bill. You only pay for the net difference.
A: A general rule of thumb is that you need approximately 200-250 square feet of shadow-free area for 3 kW of solar capacity.
A: Yes, but efficiency drops. Panels work on light intensity, not heat.
A: Yes, standard warranties typically include:
