1. What is the lifespan of a solar panel system?

A quality solar panel system typically lasts 25 to 30 years, with minimal maintenance. While panel efficiency may slightly reduce over time, they still generate significant electricity even after two decades, making solar a long-term, cost-effective investment for your home or business.

2. How much money can I save with solar panels?

You can save up to 80–90% on your monthly electricity bill, depending on your location, usage, and system size. Over 25 years, savings can run into lakhs, making solar one of the smartest financial decisions for homeowners and commercial property owners.

3. Is solar energy reliable during cloudy or rainy days?

Yes, solar panels still produce power during cloudy weather—though at reduced efficiency (about 10–25%). For consistent power, hybrid systems with battery backup or grid connection ensure uninterrupted energy supply even during poor sunlight or monsoon seasons.

4. What government subsidies are available for solar panels in India?

Under schemes like PM Surya Ghar Muft Bijli Yojana, residential users can receive 30%–40% subsidy on rooftop solar systems. Additional state-level subsidies and net metering policies make solar installation more affordable and financially rewarding for Indian households.

5. Can solar panels run an entire house or business?

Yes, a well-sized solar system can run an entire home or business. With proper load calculations, solar can power everything—lights, fans, appliances, and machines—especially when combined with batteries or net metering for round-the-clock usage.

6. Do solar panels work during a power cut?

On-grid systems shut down during power cuts for safety, but hybrid or off-grid systems with battery backup continue working. If power backup is essential, it’s best to install a hybrid solar setup for uninterrupted electricity even during outages.

7. How often do solar panels need cleaning or maintenance?

Solar panels should be cleaned every 2–4 months to remove dust, bird droppings, or leaves. Basic maintenance once or twice a year helps check wiring, inverter health, and panel alignment—ensuring your system runs efficiently for decades.

8. Can I earn money by installing solar panels?

Yes! With net metering, you can sell extra electricity back to the grid and earn credits or payments. Over time, this reduces your bill or gives you a return, making solar not just a saving tool but an income source too.

9. Are solar panels safe for rooftops and buildings?

Absolutely. Solar panels are lightweight and non-invasive, designed for rooftops without damaging structures. Proper installation by certified professionals ensures safety from electrical faults, water leaks, or load stress—while enhancing your roof’s value and utility.

10. What is the difference between on-grid, off-grid, and hybrid solar systems?

• On-grid: Connected to electricity grid; no batteries.

• Off-grid: Works independently with batteries.

• Hybrid: Combines both; uses grid + battery backup.
  Your choice depends on location, power needs, and reliability of the local electricity supply.
