The Indian government’s latest scheme — PM Surya Ghar Muft Bijli Yojana — is quickly gaining popularity across the country. Announced to provide clean and affordable electricity to common households, this initiative promises 300 units of free electricity every month to over 1 crore families. But here’s the catch: to receive this benefit, your house must have a solar system installed on the rooftop.
Now, if you’re wondering what size of solar panel system you need to enjoy the full benefit of this scheme, you’re in the right place. This article explains everything in simple language, including panel size, subsidy amount, and how to apply.
How Much Solar Power Is Needed for 300 Units?
To generate 300 units of electricity each month, the size of the solar system depends on factors like sunlight availability, your electricity usage, and space on your rooftop. On average, in India, 1kW solar system can generate 120 to 150 units of electricity monthly, provided your area gets good sunlight.
So based on this:
- 2 kW Solar System: Can produce around 240–300 units/month. This is suitable for small households with limited electricity usage.
- 3 kW Solar System: Can generate about 360–450 units/month, making it a safer and more reliable choice for those who want to ensure they always hit the 300-unit target.
A 3 kW system also gives you the opportunity to sell excess electricity back to the grid, turning your rooftop into a mini power station!
What is the Subsidy Offered by the Government?
One of the biggest benefits of this scheme is the attractive subsidy offered to homeowners. The central government is offering up to ₹78,000 for systems up to 3kW capacity. Below is a table with the detailed subsidy structure:
| System Capacity | Subsidy Amount |
| Up to 1 kW | ₹30,000 |
| Up to 2 kW | ₹60,000 (₹30k × 2) |
| Up to 3 kW | ₹78,000 (₹60k + ₹18k) |
Here’s what you may pay after subsidy:
- 2 kW system: Costs around ₹1–1.2 lakh. After ₹60,000 subsidy, you pay only ₹40,000–60,000.
- 3 kW system: Total cost is about ₹1.45–1.90 lakh. After ₹78,000 subsidy, your share is ₹67,000–1.12 lakh.
The subsidy is directly credited to your bank account within 30–45 days after installation and approval.
Who is Eligible and What Do You Need?
To take benefit of this scheme, you must fulfill some basic requirements:
- Must be an Indian citizen.
- Should have ownership of the house with proper rooftop space.
- Should have a valid electricity connection.
- Must not have availed any previous solar subsidy.
These points make it clear that the scheme is focused on helping genuine homeowners who want to reduce their power bills and move toward clean energy.
