Solar System
Total DC wattage of your solar panels.
Total energy your appliances use per day.
Peak sun hours at your location. Pakistan avg: 5–7 hrs.
Accounts for losses (inverter, wiring, dust). Typical: 0.75–0.82.
Battery System
Ampere-hour rating on your battery bank.
Days of backup without solar recharge.
Hours per night you run appliances from battery.
Whether grid is available as fallback source.

* Daily Generation = Solar kW × Sun Hours × Performance Ratio. Battery usable energy = Voltage × Ah ÷ 1000 × DoD. Coverage split: solar portion capped at daily load, remaining gap filled by battery then grid. Cost estimates: panels @ Rs 55/W, battery @ Rs 70,000/kWh usable, inverter + misc @ Rs 55,000/kW. Values are indicative only.
