Frequently Asked Questions

Solar panels absorb sunlight with photovoltaic cells, generating direct current (DC) energy. An inverter converts the DC energy into usable alternating current (AC) energy, which then flows through your home's electrical panel to power your appliances.

Solar panels need sunlight to generate power. On cloudy days, they will produce less electricity. At night, they produce no power. In an On-Grid system, you automatically draw power from the electricity grid at night. The excess power you exported to the grid during the day acts as a credit against this night usage.

Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. For example, if your solar panels produce more electricity than your home uses during the day, the excess is sent back to the grid, and your utility meter effectively runs backward.

Typically, you need about 100 square feet of shadow-free rooftop space for every 1 kW of solar capacity. A standard 3 kW system for a home would require roughly 300 square feet.

No. When installed properly by professionals like Solvanta Solar, solar panels actually protect the portion of the roof they cover from weather and sun damage. We use specialized mounting structures that do not compromise the integrity or waterproofing of your roof.

The physical installation of the panels and inverter on your property typically takes 1 to 3 days depending on the system size. However, the complete process, including DISCOM approvals and net meter installation, can take 3 to 6 weeks.

Solar panels require very little maintenance since there are no moving parts. The main requirement is keeping them clean from dust and bird droppings. Washing them with water every 15-20 days is usually sufficient. We also offer Annual Maintenance Contracts (AMC) for complete peace of mind.

You are eligible if you have a residential property (not commercial), an active electricity connection in your name, and you choose an empaneled vendor like Solvanta Solar for the installation.

Currently, the subsidy is ₹30,000 per kW up to 2 kW capacity, and ₹18,000 for the additional 1 kW. The maximum subsidy is capped at ₹78,000 for systems of 3 kW or larger.

For residential systems, the ROI period is typically 3 to 5 years, especially when factoring in the government subsidy. Since the panels have a lifespan of 25 years, you effectively get 20+ years of free electricity after recovering the initial cost. Commercial ROI is often even faster (2-4 years) due to accelerated depreciation tax benefits.
