Ghar Ke Liye Sahi Solar Capacity Ka Intikhab Kyun Zaroori Hai?
Pakistan mein solar system lagwate waqt aksar log ya to **under-sized** system lagwa lete hain jisse AC chalte hi grid se units girne lagte hain, ya phir **over-sized** system par be-wajah lakhon rupay zaya kar dete hain.
Sahi capacity ka ta-ayyun karne ke liye aapko apne **Summer Peak Load (kW)** aur **Daily Units Burn Rate (kWh)** ko calculate karna zaroori hai.
1. Household Load vs Recommended Solar System Size
| System Size | Inverter Type | Solar Panels Required | Daily Units Generated | Kya Kya Chala Sakta Hai? |
|---|---|---|---|---|
| 3.2 kW | Hybrid / On-grid | 6 x 585W Panels | 12 – 14 Units | 1 Inverter AC (Din mein) + 1 Fridge + Lights/Fans |
| 5.5 kW | Hybrid / On-grid | 10 x 585W Panels | 20 – 24 Units | 2 Inverter ACs + 1HP Water Pump + Full Home |
| 10 kW | 3-Phase On-grid | 18 x 585W Panels | 40 – 48 Units | 3–4 ACs + Deep Freezer + Complete Home + Export Units |
| 15 kW | 3-Phase On-grid | 26 x 585W Panels | 60 – 72 Units | 1 Kanal / Commercial Bungalow with High Net Metering |
2. Solar System Sizing Ka Practical Formula
$$\text{Required Panels (kW)} = \frac{\text{Average Daily Units Consumption}}{\text{Peak Sun Hours (4.5)}} \times 1.25$$
