| Property | Retail shop, Neyyattinkara |
|---|---|
| Connection | Commercial (LT) |
| Loads | Lighting, fans, refrigeration, billing counter, AC |
| System | ≈ 5 kW on-grid |
| Bill reduction | ≈ 75–85% of energy charges |
| Investment | ≈ ₹2.8–3.2 lakh, no PM Surya Ghar subsidy |
| Payback | ≈ 3.5–4.5 years |
The problem
A shop that opens at 9 am and closes after 8 pm pays commercial rates on lights, refrigeration and cooling. Almost all of the consumption happens while the sun is up.
What we designed
- A modest on-grid system sized to the shop's daytime load, so nearly every unit generated is used on site.
- Roof access arranged with the building owner and a written consent.
- A structure suited to the existing roof sheet and local wind.
The result
The energy charges on the monthly bill fell by roughly three quarters or more, while fixed charges remain. Because this is a commercial connection the central household subsidy does not apply, so payback comes from tariff savings and, where applicable, depreciation.
Takeaway for shop owners
Daytime-heavy businesses are often the best fit for solar. Read our small shop guide and try the calculator with your bill.
Figures are indicative of this type of project; actual results depend on tariff category, roof and consumption pattern.
