Islamabad averages 5.0 sun hours per day. Winter fog and altitude pull the daily figure down vs the plains. Use the designer below to size a system for your home or business. Pre-filled with Islamabad sun hours; pick your DISCO (IESCO) when prompted.
Check your last DISCO bill — look for “Units consumed”.
≈ 500 units/month · ~17 units/day
We use local sun-hours data to estimate your generation.
Lahore gets ~5.5 sun-hours/day → expect ~132 units/month per kW installed.
Pick the goal that matches your situation.
Most homes pick 4–6 hours to cover evening peak. Choose 0h for grid-tied operation without battery.
Standard panels today are 580–610W. Leave at 585W unless your installer specifies otherwise.
Islamabad sits in ICT and is served by IESCO. With 5 peak sun hours per day, a typical 10 kW rooftop system here generates around 1200 kWh per month after standard inverter, wiring, and dust losses are accounted for. That's enough to wipe out the daytime electricity use of a mid-sized Islamabad home.
Since February 2026, all new solar connections in Pakistan — including IESCO — fall under NEPRA's net billing framework instead of the old net metering regime. That means exported units now earn Rs 8–11 per unit instead of the old Rs 25.32. The economics still work, but the right system in Islamabad is one sized to your daytime consumption, not your total monthly units. Run AC, appliances, and water pumps during solar hours and you save the full retail tariff on every kWh you self-consume.
How many solar panels do I need for a 10 kW system in Islamabad?
A 10 kW system uses about 17 panels at 585 W each. With Islamabad's 5 sun hours per day, that system generates roughly 1200 kWh per month.
What is the cost of a 5 kW solar system in Islamabad in 2026?
A 5 kW on-grid system in Islamabad costs approximately Rs 450,000 to 550,000 in May 2026 — including 9× 585 W panels, a 5 kW on-grid inverter, mounting structure, wiring, and installation. A hybrid 5 kW system with a 5 kWh LiFePO4 battery runs Rs 800,000 to 950,000.
What's the payback period for solar in Islamabad?
Under the new 2026 net billing rules and IESCO tariffs, typical payback in Islamabad is 4–6 years for an on-grid system sized to daytime consumption, and 6–8 years for a hybrid system. After payback, the system produces near-free electricity for another 15–20 years.
Is Islamabad good for solar?
Islamabad averages 5.0 sun hours per day. Winter fog and altitude pull the daily figure down vs the plains. That makes Islamabad solid solar territory — most rooftop installations there pay back within 6 years at current tariffs.
Which DISCO handles net metering in Islamabad?
Islamabad is served by IESCO. Net metering applications are submitted to IESCO's commercial office along with NTN, CNIC, sanctioned-load proof, and your AEDB-listed installer's design package.
