Solar System Sizing & Price Components
The total cost of a solar rooftop system in India depends on several factors including the type of solar panels (Polycrystalline vs Mono-PERC vs Bifacial), the quality of the solar inverter, and the complexity of the mounting structure.
Understanding the Subsidy (PM Surya Ghar)
The Government of India provides a fixed subsidy based on the solar system capacity for residential homes:
- 1kW: ₹30,000 subsidy
- 2kW: ₹60,000 subsidy
- 3kW or more: ₹78,000 (Maximum cap)
How to Choose the Right Capacity?
A general rule of thumb for selecting solar capacity in India is checking your monthly electricity consumption (Units/kWh):
- 0-150 Units: 1kW System
- 150-300 Units: 2kW System
- 300-500 Units: 3kW-4kW System
- 500+ Units: 5kW or more
