Commercial and residential solar use the same core technology, but the projects differ in almost every other way.
What changes
- Scale — commercial projects run into hundreds of kW or MW.
- Subsidy — PM Surya Ghar applies to residential only.
- Decision-makers — commercial deals involve procurement teams, not one homeowner.
- Payback focus — commercial buyers weigh depreciation benefits too.
"Residential solar sells on savings. Commercial solar sells on balance sheet impact."
| Residential | Commercial | |
|---|---|---|
| Typical size | 2–10 kW | 50 kW+ |
Larger projects need tighter sizing accuracy — see how Solar 3D Design scales up to 5 MW layouts.
