In India, solar panel prices have become more affordable in recent years due to advancements in technology and government incentives promoting clean energy. On average, the price of solar panels in India ranges from ₹25 to ₹45 per watt, depending on the type of panel, its efficiency, and the manufacturer.
For residential solar installations, a typical 1 kW system can cost between ₹25,000 to ₹45,000, excluding installation costs. The overall price for a 3 kW to 5 kW system, which is commonly used for homes, could range from ₹75,000 to ₹2,25,000. These prices may vary depending on the type of solar panels—monocrystalline panels are generally more expensive but offer higher efficiency compared to polycrystalline panels.
India also offers various government subsidies and incentives under schemes like PM-KUSUM and the Rooftop Solar Programme, which can further reduce the cost of installing solar panels.

Subsidy for Solar Panels in India:
The Indian government provides substantial subsidies to encourage the adoption of solar energy through schemes like the Rooftop Solar Programme and PM-KUSUM. These subsidies are aimed at reducing the financial burden on residential, agricultural, and commercial users.
- Rooftop Solar Subsidy:
- The government offers subsidies of up to 40% for residential solar installations up to 3 kW capacity.
- For systems between 3 kW and 10 kW, the subsidy is 20%.
- For larger installations (above 10 kW), there is no subsidy.
- PM-KUSUM Scheme: This scheme focuses on promoting solar energy in agriculture. Farmers can receive up to 60% subsidy for installing solar pumps and panels to power their irrigation systems.
- There are three main types of solar panels commonly used in residential and commercial applications. Each type has its own advantages in terms of efficiency, cost, and suitability for different environments.
- 1. Monocrystalline Solar Panels:
- Efficiency: High efficiency (15-22%) due to the use of high-purity silicon.
- Appearance: Black in color with rounded edges.
- Advantages: These panels are known for their excellent performance in low-light conditions and require less space to generate the same amount of energy compared to other types.
- Cost: Typically the most expensive, but their higher efficiency makes them ideal for areas with limited space.
- 2. Polycrystalline Solar Panels:
- Efficiency: Moderate efficiency (13-16%), lower than monocrystalline.
- Appearance: Blue in color with a speckled texture.
- Advantages: These panels are more affordable due to the simpler manufacturing process and are widely available.
- Cost: Cheaper than monocrystalline panels but less efficient, requiring more space to produce the same amount of energy.
- 3. Thin-Film Solar Panels:
- Efficiency: Lower efficiency (10-12%) compared to crystalline-based panels.
- Appearance: Sleek and flexible, often black or dark blue.
- Advantages: Lightweight, flexible, and easy to install on various surfaces, including curved or irregular ones. They perform better in hot temperatures and partial shading.
- Cost: Generally cheaper, but due to their lower efficiency, more panels are needed to generate the same power.
- Comparison Summary:
- Monocrystalline Panels: Best for efficiency and space-saving but expensive.
- Polycrystalline Panels: More affordable but require more space and are less efficient.
- Thin-Film Panels: Ideal for non-traditional installations, but less efficient and require more surface area.
