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)
Installation & Structure
Mounting Structure: ₹40,000 (rcc type)
Installation: ₹40,000 (metro rates)
Final Calculation
Subtotal: ₹3,33,000 + GST (12%): ₹39,960 = ₹3,72,960
Cost Variations
Costs vary by location, roof type, and system configuration. Ground mounting and off-grid systems cost more due to complexity.
Installation Process & Tips
Installation Steps:
- • Site Survey: Roof assessment and shading analysis
- • Design: System layout and component selection
- • Permits: Electricity board approvals
- • Installation: Mounting, wiring, and commissioning
Cost Optimization:
- • Choose appropriate system type for your needs
- • Consider local installation rates
- • Compare quotes from multiple vendors
- • Check for government subsidies and incentives
Your 5kW System Estimate:
The Solar Installation Cost Calculator gives homeowners and businesses in India a detailed, itemized estimate of what a rooftop solar system will cost to install, covering panels, inverter, battery (if applicable), mounting structure, wiring, labour and GST — useful for budgeting before requesting vendor quotes.
Solar Installation Cost Calculator - FAQs
What's included in the total solar installation cost?
The estimate covers solar panels, inverter, battery (for off-grid/hybrid systems), mounting structure, wiring and accessories (10% of equipment cost), installation labour, and 12% GST on solar systems.
Why does roof type affect the cost?
Mounting structure costs vary by roof — RCC roofs are cheapest to mount on (around ₹8,000/kW) while ground-mounted systems need more structural work (around ₹15,000/kW).
Why does my city or location change the price?
Installation labour rates differ by location — metro cities charge more (around ₹8,000/kW) than rural areas (around ₹4,000/kW) due to differences in labour and logistics costs.
Does this estimate include the government subsidy?
No, this calculator shows the gross installation cost before any subsidy. Use the Solar Subsidy Calculator to see your net cost after PM Surya Ghar Yojana and state incentives.
How accurate is the ₹38/watt panel price used here?
Panel and component prices fluctuate with market conditions and technology, and subsidy or GST rules can also change over time. Treat this as a ballpark estimate and get vendor quotes for an exact price.
