Kitna solar chahiye?
Jo cheezein din mein chalani hain unki tadaad likho. Andaza Pakistan ke 4.5 sun-hours par hai.
Samajhne ke liye
- Hybrid — din mein solar, raat ko battery ya grid. Load-shedding walon ke liye.
- On-grid (net metering) — battery nahi, extra bijli WAPDA ko bechte ho, bill kam. Load-shedding mein band.
- Battery — lithium 5kWh ≈ raat ko 2 fan + lights + 1 AC 3–4 ghante.
- 1 ton inverter AC ≈ 2 panels se chalta hai, 1.5 ton ≈ 3 panels (din mein).
