How Solar Installation Cost Works

Equipment Costs

Solar Panels:1,90,000 (5kW × 1000W × ₹38/W)

Inverter:40,000 (grid-tied type at different rates)

Total equipment: ₹2,30,000

Installation & Structure

Mounting Structure: ₹40,000 (rcc type)

Installation: ₹40,000 (metro rates)

Wiring & Accessories: ₹23,000 (10% of equipment cost)

Final Calculation

Subtotal: ₹3,33,000 + GST (12%): ₹39,960 = ₹3,72,960

Cost per watt: ₹3,72,960 ÷ 5000W = ₹66.6/W

Cost Variations

Costs vary by location, roof type, and system configuration. Ground mounting and off-grid systems cost more due to complexity.

Metro installation: ₹8K/kW | Rural: ₹4K/kW | RCC roof: ₹8K/kW | Ground mount: ₹15K/kW
