Detailed Price Breakdown of Rooftop Solar System
Here is how the total cost is divided:
1. Solar Panels (40–50%)
Solar panels are the main component. High-efficiency monocrystalline panels cost more but generate more power.
2. Solar Inverter (15–20%)
The inverter converts DC electricity into usable AC power. String inverters are cheaper, while hybrid inverters cost more.
3. Mounting Structure (10%)
This supports panels on the roof and must be strong and rust-resistant.
4. Wiring & Electrical Components (5–8%)
Includes DC cables, AC cables, junction boxes, and safety devices.
5. Installation & Labor (8–12%)
Professional installation ensures safety, performance, and warranty protection.
