| A Complete Guide for Installing Solar Panel |
In 2025, solar energy is gaining massive popularity among Indian homeowners who aim to reduce electricity bills and adopt an eco-friendly lifestyle. This guide covers everything from solar panel types to installation costs, government subsidies, and long-term savings.
What Are Solar Panels and How Do They Work?
Solar panels use photovoltaic cells to convert sunlight into electricity. These panels are installed on rooftops and generate power during the day. You can either use this electricity directly or store it in batteries. With net metering, any extra power goes back to the electricity grid, and you get credits.
Types of Solar Systems
There are three primary types of solar systems in India:
- On-Grid System: Connected to the electricity grid. No batteries. Perfect for homes in cities.
- Off-Grid System: Works independently using batteries. Ideal for remote areas with no electricity.
- Hybrid System: Combines on-grid and battery storage. Offers maximum flexibility.
Popular Types of Solar Panels
- Monocrystalline Panels: High efficiency and performance. Slightly more expensive.
- Polycrystalline Panels: Affordable and widely used in Indian homes.
- PERC Panels: Advanced version of mono panels. Great performance even in low light.
Approximate Price Range of Solar Systems in 2025
The price of solar panels depends on the system capacity and brand. Here’s a simplified overview:
- 1 kW System: ₹45,000 – ₹65,000 (suitable for fans, lights, TV)
- 3 kW System: ₹1.2L – ₹1.6L (suitable for 2 BHK homes)
- 5 kW System: ₹2L – ₹2.4L (suitable for larger homes)
- 10 kW System: ₹4L – ₹5.5L (suitable for villas or small businesses)
Government Subsidy for Solar Installation
The Indian government, through MNRE, offers attractive subsidies:
- 40% subsidy for systems up to 3 kW
- 20% subsidy for 3–10 kW systems

Net Metering – Save More Every Month
Net metering allows you to send surplus electricity to the power grid. Your electricity bill is adjusted based on the net usage. It significantly reduces your monthly energy expenses and sometimes even gives you a credit.
How Much Can You Save?
Monthly savings depend on your system size and electricity consumption. For example:
- 1 kW System: Save ₹900 – ₹1,200/month
- 3 kW System: Save ₹2,500 – ₹3,000/month
- 5 kW System: Save ₹4,000 – ₹5,000/month
Most homeowners recover the full investment within 4–6 years.
