1. How much does it cost to install solar panels?
Estimated Costs by System Size (Before Subsidy) (2026)
| System Size | Typical Use Case | Estimated Cost Range |
|---|---|---|
| 3 kW | 2–3 BHK homes (standard appliances) | ₹2,25,000 – ₹2,40,000 |
| 5 kW | Large homes (includes AC, geysers) | ₹3,75,000 – ₹3,95,000 |
| 10 kW | Large villas or small offices | ₹7,50,000 – ₹7,90,000 |
2. Are there any government incentives for solar ?
Central Government Subsidy (PM-Surya Ghar). The subsidy amount is based on the capacity of the solar plant you install:
3. How much can I save by switching to solar?
Estimated Monthly & Annual Savings
| System Size | Monthly Generation | Avg. Monthly Savings | Avg. Annual Savings |
|---|---|---|---|
| 3 kW | 450 – 600 units | ₹2,000 – ₹2,800 | ₹24,000 – ₹33,600 |
| 5 kW | 750 – 1050 units | ₹7,000 – ₹7,500 | ₹84,000 – ₹90,000 |
| 10 kW | 1500 – 2100 units | ₹13,000 – ₹21,000 | ₹1,56,000 – ₹2,52,000 |
4. Do solar Panels work on cloudy days?
Solar panels typically produce between 10% and 50% of their rated capacity on overcast days, depending on the density of the cloud cover:
Partly Cloudy: Systems often maintain 50% to 80% of their peak output.
Heavy Overcast/Rain: Generation typically drops to 25% to 50% of its normal capacity.
5. Will Solar panels work during a power outage?
- Grid-Tied Systems
Standard grid-tied solar systems automatically shut down during a power outage as a safety feature. This protects utility workers repairing power lines. As a result, your home will not receive solar power during the outage. - Hybrid Systems
Hybrid solar systems can continue supplying power during outages. The system automatically switches to battery backup and uses available solar energy to run selected essential appliances such as lights, fans, and refrigerators. - Off-Grid Systems
Off-grid solar systems operate independently from the utility grid. They continue to provide power during outages using solar panels and battery storage, based on system.
