What Appliances Can a 5kW System Run?
- 2 × 1.5-ton inverter ACs running simultaneously (daytime)
- Full household: fans, lights, refrigerator, TV, washing machine
- Small office: computers, printers, AC, lighting
- Surplus generation exported via net metering for evening bill offset
5kW System Payback Calculator
| Bill Before Solar | Monthly Saving | System Cost | Payback Period |
|---|---|---|---|
| Rs 15,000/month | Rs 15,000 (full offset) | Rs 380,000–440,000 | 25–30 months |
| Rs 25,000/month | Rs 22,000–25,000 | Rs 380,000–440,000 | 16–20 months |
| Rs 40,000/month | Rs 25,000–28,000 | Rs 380,000–440,000 | 14–18 months |
The higher your current electricity bill, the faster a 5kW system pays back. At Rs 40,000+/month, payback is under 18 months. At Rs 15,000/month, it takes 25–30 months but you still save Rs 18M+ over the system’s 25-year life.
