FAQ

Solar energy is energy derived by converting sunlight into usable energy for homes and offices. It is versatile, consistent, renewable, and free.

Solar energy systems can be costly upfront, starting from Rs. 2,00,000. However, energy itself is free, and Tamil Nadu's feed-in tariff scheme allows earning from excess energy generated.

A shade-free rooftop area and a sunny climate are essential. South India, with abundant sunny days, offers optimal conditions for solar power generation.

Photovoltaic modules expose silicon layers to sunlight, creating an electrical field that generates voltage. The energy can be stored or sent to the grid.

Yes, solar panels designed with positive tolerances can generate energy in low-light conditions, though not as much as on sunny days.

A unit equals one kilowatt-hour (kWh). For example, a 2.0 kWh-rated air-conditioner uses 2.0 units per hour under continuous load.

Photovoltaic cells use crystalline silicon layers, doped with boron and phosphorus. Sunlight creates voltage between positive and negative silicon layers, producing current flow.

The payback period varies. It depends on energy needs and economic factors like inflation and electricity costs. Tools like calculators can provide estimates.

A grid-tied system includes PV modules, a combiner box, a solar inverter, cables, and an isolator. Larger systems may include enhanced earthing and lightning protection.

Solar plants are reliable with built-in redundancies and overcapacity. These features enhance durability and ensure consistent energy generation.

Solar plants are designed to minimize components and maximize efficiency. Daystar inverters offer up to 98% efficiency, reducing system losses.

Solar power reduces fossil fuel use, cutting harmful emissions like carbon dioxide. This improves air quality and reduces health risks.

For every 1000 watts of solar capacity, approximately 75 sq. ft. of space is needed, plus 25 sq. ft. for accessibility.

Yes, grid-tie plants support single or three-phase configurations for heavy loads. Systems can scale up to 1000KW using stacking.

Yes, institutions like schools, malls, and offices can benefit from solar, reducing energy costs and boosting profitability.

There is no limit as long as space is available. Overcapacity can also be installed to cater to future demand.

Solar installations reduce dependency on fossil fuels, cutting carbon dioxide emissions and supporting sustainable energy consumption.

Electricity costs accumulate over a lifetime. Solar energy offers savings, eco-friendliness, and protection against future cost inflation.
