CALCULATED ON YOUR DEVICEHow the calculation works
Annual generation = panel capacity × peak sun hours × 365 × performance ratio. Monthly direct use is the lower of average solar generation and the consumption you assign to solar hours. Savings = direct use × your energy rate. No value is assigned to surplus.
Resicon confirmed its indicative installed prices on 30 September 2026: PKR 148,000/kWp up to 5 kWp; 132,000 up to 10; 122,000 up to 20; 112,000 up to 50; and 100,000 above 50. The supplied commercial adjustment is 12% lower. A written quote overrides these estimates. Batteries are excluded; confirm equipment and scope with the team.
Simple payback divides initial cost by annual energy savings. It excludes finance, degradation, maintenance, replacements and future tariff changes. It is not an investment return calculation. Monthly and seasonal production will vary.
Check your distributor’s rate and NEPRA bill guidance. For a site-specific generation assessment, review shading, orientation and equipment with an installer; tools such as PVWatts model more of these variables. This calculator does not use the PVWatts model.
Bring the whole picture.
Several months of bills, roof photographs and a list of essential appliances help the survey team design for your actual demand.
Talk to the survey teamkW and kWh measure different things
kW describes power; kWh measures energy over time. Panel capacity does not guarantee the same output in every hour.
Need power after sunset?
Battery storage needs a separate assessment of backup hours, usable capacity and essential circuits.
