The basic formula
Required home capacity = Monthly electricity use (kWh) × 12 / 1,500
In Uzbekistan, 1 kWp of panels produces on average 1,500 kWh/year.
Example for a family of four
- Monthly use: 400 kWh
- Annual: 4,800 kWh
- Required: 4,800 / 1,500 ≈ 3.2 kWp (6 × 550W panels)
If you have air conditioning
Each air conditioner needs an extra 1.5–2 kWp. With 2 air conditioners, a total of 6–7 kWp is recommended.
Quick table for your family
| Household size | Use (kWh/month) | Recommended kWp |
|---|---|---|
| 2 people | 200 | 2 kWp |
| 4 people | 400 | 4 kWp |
| 4 + air conditioning | 600 | 6 kWp |
| Large house | 800+ | 8–10 kWp |
