Frequently Asked Questions
PM Surya Ghar Muft Bijli Yojana offers central government subsidy for residential rooftop solar: ₹30,000/kW for the first 1 kW, ₹18,000/kW for 1-2 kW, and ₹9,000/kW for capacity beyond 2 kW up to a maximum of ₹78,000 for 3 kW and ₹1,08,000 for up to 10 kW systems. Apply via the PM Surya Ghar portal at pmsuryagarh.gov.in.
A 10 kW on-grid solar system in India typically costs ₹4.5–6.5 lakh before subsidy (2025-26 prices), depending on panel brand, inverter quality, and mounting structure. After PM Surya Ghar subsidy of up to ₹1,08,000, the net cost is approximately ₹3.4–5.4 lakh. A 10 kW system generates approximately 13,000–15,000 kWh annually.
The payback period for rooftop solar in India is typically 3–6 years, depending on system size, electricity tariff, and available sunlight hours. At ₹8/unit tariff with 5 peak sun hours, a 10 kW system saves approximately ₹1–1.2 lakh per year, giving a payback of 4–5 years. Over 25 years, the savings can be 5–8 times the system cost.
A complete rooftop solar installation includes: solar panels, string inverter or microinverters, mounting structure, DC cables and conduits, AC cables, ACDB (AC Distribution Box), DCDB (DC Distribution Box), earthing and lightning protection, bi-directional/net metering, monitoring system, and civil work and labour charges.
On-grid solar is connected to the electricity grid — it feeds excess power back to the grid and earns net metering credits. Off-grid solar uses batteries for storage and works independently of the grid — ideal for areas with no grid supply. Hybrid solar has both grid connection and battery storage, providing backup during outages while also benefiting from net metering.
