FAQs

1. What is the typical rooftop solar system cost in India for residential installations?

The cost of residential rooftop solar systems depends on capacity, panel type, and equipment quality. On average, a 3–5 kW system ranges between ₹1.5 lakh to ₹3 lakh. Subsidies and incentives can significantly reduce upfront expenses, improving the return on investment and payback period.

2. How do I apply for a rooftop solar subsidy in India?

Applications for rooftop solar subsidy in India are submitted through state nodal agencies or MNRE-approved channels. The process involves site assessment, documentation, system design approval, and post-installation inspection. Neutron Solar assists clients in completing all formalities to ensure seamless access to government incentives and lower system costs.

3. What is net metering rooftop solar in India, and how does it work?

Net metering rooftop solar in India allows excess electricity generated to be exported to the grid. A bi-directional meter records both consumption and supply. Users receive credits for surplus energy, offsetting future bills. This system improves financial returns and encourages efficient utilization of rooftop solar energy in India.

4. How long does a rooftop solar installation in India take?

The duration varies with system size and complexity. Residential installations typically take 7–15 days, while commercial or industrial projects may require 3–6 weeks. Factors include site assessment, approvals, equipment delivery, and installation. Proper planning ensures timely commissioning and integration with net metering rooftop solar in India.

5. Can rooftop solar energy in India provide electricity during grid outages?

Grid-connected systems without batteries will not supply power during outages. Hybrid or off-grid systems with battery storage store excess electricity for backup. These systems provide continuous electricity, ensuring an uninterrupted supply for homes, businesses, or industrial facilities even during grid downtime.

6. What maintenance is required for rooftop solar panels?

Regular cleaning of panels, inspection of inverters, monitoring battery health, and checking electrical connections are essential. Dust, debris, or minor faults can reduce efficiency. Using monitoring systems and long-term service agreements ensures consistent performance and maximizes energy production for residential, commercial, and industrial rooftop solar installations.

7. How long do rooftop solar panels last?

High-quality solar panels typically have a lifespan of 25–30 years. Inverters may need replacement after 10–15 years. Proper installation, regular maintenance, and monitoring ensure long-term performance. Durability is enhanced by selecting reliable equipment and adhering to installation standards for rooftop solar energy in India.

8. Are commercial rooftop solar systems eligible for tax benefits?

Yes, commercial and industrial systems can avail accelerated depreciation and GST benefits. These tax incentives reduce overall project costs, improve financial returns, and shorten payback periods. Government subsidies and net metering for rooftop solar in India further enhance the economic viability of commercial rooftop solar power projects in India.

9. How is the energy output of a rooftop solar system monitored?

Monitoring systems track real-time energy generation, consumption, and battery status. Alerts notify users of performance deviations or faults. Remote access via web or mobile platforms allows homeowners and businesses to monitor efficiency, optimize usage, and maintain compliance with net metering rooftop solar India regulations.

10. What factors determine the size of a rooftop solar power plant in India?

System size depends on energy consumption, rooftop area, orientation, shading, and available budget. Residential, commercial, and industrial buildings have varying requirements. Proper site assessment and design by professionals like Neutron Solar ensure the system meets electricity needs efficiently while maximizing financial and environmental benefits.
