Solar System Size & Price Calculator Pakistan
How many kW of solar you need, what a 5kW or 10kW system costs in Pakistan, your monthly saving with net metering and the payback period.
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.
