On average, a 1 kW solar system requires approximately 100 square feet of shadow-free space. The actual space may vary depending on the type and efficiency of the solar panels.

The cost of installing a rooftop solar system in India ranges from ₹50,000 to ₹70,000 per kW, depending on the type of panels, inverter, and other components. Government subsidies can significantly reduce this cost for residential systems.

A 1 kW solar system generates approximately 4–5 units of electricity per day under optimal sunlight conditions, depending on the location and weather.

Solar panels typically last 20–25 years, with most manufacturers offering performance warranties for this duration. Proper maintenance can ensure they perform efficiently throughout their lifespan.

Yes, solar panels can generate electricity during cloudy or rainy days, but the output will be lower compared to sunny days. Advanced panels perform better in diffused sunlight.

Yes, a properly sized solar system can power an entire home. However, the feasibility depends on your energy consumption, available roof space, and budget for installing a system with sufficient capacity.

Battery storage is not mandatory for grid-tied systems, as excess electricity can be sent to the grid. However, batteries are essential for off-grid or hybrid systems to store energy for backup during power cuts.

Solar panels require minimal maintenance. Cleaning them every 2–4 weeks to remove dust and debris is sufficient in most cases. Additionally, scheduling an annual professional check-up can ensure the system is functioning efficiently.
