Rooftop Solar (On-Grid)
The most common configuration, where power is generated on your roof, consumed on site first and exported as the balance.

About the Ground-Mounted Solar
- Modules sit at the optimum tilt rather than the roof's angle, which lifts annual yield per panel above an equivalent rooftop plant.
- Cleaning, inspection and string replacement happen at ground level, so operations and maintenance cost less over the plant's life.
- Civil work, foundations, fencing and cable trenching make the capital cost per kWp higher than rooftop, and the payback comes from yield and lifespan.
- Land use has to be agreed early. It is the one input that cannot be revised after the layout is fixed.
Specifications
- System size100 kWp to 20 MWp
- Land required4 to 5 acres per MWp
- StructureFixed tilt or seasonally adjustable
- FoundationScrew pile or RCC pedestal
- Typical yield1,400 to 1,700 kWh per kWp per year
