How this is calculated

System size = monthly units ÷ (peak sun hours × 30 × 0.8). The 0.8 derate accounts for inverter efficiency, heat, dust and wiring losses typical in Pakistan.

Savings = units you consume directly × your full per-unit cost + units exported × the DISCO's export credit rate. Direct use is worth more than export, so daytime consumption (ACs, pumps, washing) improves the return.

Payback = installed cost ÷ annual savings. Panels are warranted for 25 years; inverters typically need replacement once in that period, which the lifetime figure approximates with a 10% haircut.

Frequently asked questions

How much does a 5 kW solar system cost in Pakistan?
In 2026, roughly Rs 550,000–800,000 installed depending on panel tier, inverter brand and structure. Get three quotes from listed installers.
What is net metering?
A bi-directional meter that records what you import and export. Under NEPRA's 2026 Prosumer Regulations exports are credited at the national average energy purchase price (net billing) rather than one-for-one. Applications go through your DISCO, then NEPRA concurrence.
Do I need batteries?
Not for net metering. Batteries add cost and are only worthwhile if load-shedding or backup is the goal.
Which direction should panels face?
South-facing at roughly your latitude (25–33°) in Pakistan gives the best annual yield.
