Solar Installation Business Profitability in India (2026)
The solar installation business in India is booming — PM Surya Ghar alone targets 1 crore households. An active installer doing 8–15 residential projects per month can earn ₹3–₹8 lakhs monthly profit. Here's how to structure your business for maximum margin.
Typical Cost Structure for Solar Installers
- Solar Panels: ₹20–₹28/W (DCR Waaree/Adani) — largest cost component
- Inverter: ₹6–₹10/W (Solis, SolarEdge, Growatt)
- Mounting Structure: ₹4–₹6/W
- Wiring + BOS: ₹3–₹5/W
- Installation Labour: ₹2–₹4/W
- Net Meter Charges: ₹2,000–₹5,000 per project
- Total Cost: ₹35–₹42/W for quality residential systems
Pricing Strategy for Maximum Margin
Most residential installers price at ₹48–₹58/W, giving a gross margin of 25–40%. Factors that justify higher pricing: brand reputation, faster DISCOM approvals, quality panel brands, and post-installation AMC.
Subsidy Processing: How Installers Get Paid
For PM Surya Ghar projects, installers typically collect 60–70% upfront from the customer, complete installation, and the customer receives the ₹78,000 subsidy directly in their bank — which they then pay to the installer. Always structure your contracts to account for the 30–45 day subsidy disbursement timeline.
