20kW Solar System Price in Pakistan (2026)
20kW solar system price in Pakistan in 2026, units per day and month, load capacity, number of panels, battery backup, and on-grid vs hybrid.
Current listed prices on GreenOH (26 October 2026)
Installed prices from packages published by verified installers. Final prices are confirmed after a site survey.
Short answer: what does a 20kW solar system cost?
A complete 20kW hybrid solar system with lithium battery storage is listed on GreenOH at Rs 3,090,000, installed, as of October 2026. That is about Rs 154 per watt, and the final price is confirmed after a site survey.
Without batteries, an on-grid 20kW system costs less. GreenOH's planning estimate is about Rs 140 per watt for on-grid, or roughly Rs 2,800,000, but exact prices depend on the panels, inverter and installation.
Prices move with the dollar and import costs, so check the live price box above and compare complete, itemised quotations.
How many units does a 20kW system produce?
With about 20% system losses, a 20kW system produces roughly 88 units a day in Karachi, or about 2,640 units a month. In Lahore expect about 2,400 units a month and in Islamabad about 2,304.
Output is higher in summer and lower in winter. Dust, shade and panel angle all reduce it, so clean panels regularly and ask the installer for a month-by-month estimate.
| City | Peak sun hours | Units per day | Units per month |
|---|---|---|---|
| Karachi | 5.5 | 88 | 2,640 |
| Multan | 5.4 | 86 | 2,592 |
| Faisalabad | 5.1 | 82 | 2,448 |
| Lahore | 5.0 | 80 | 2,400 |
| Islamabad | 4.8 | 77 | 2,304 |
20kW solar system load capacity: what can it run?
A 20kW system suits a home or business using about 2,000–2,600 units a month: a large house, office, clinic, school or small factory with heavy daytime use.
In strong sun, real output is usually around 75–85% of the panel rating, so plan daytime loads below that. Running ACs for long hours, or at night, depends on battery size. Check the input power on each appliance's nameplate and add up what runs at the same time.
- Panels: 40 × 550W (about 22.0 kW of panels)
- Roof space: roughly 120–145 square metres of shade-free roof
- Inverter: 20kW hybrid inverter
- Battery in the listed package: 30.72–40.96 kWh lithium, expandable
- Backup in the listed package: about 6–16 hours, depending on load
On-grid or hybrid for 20kW?
Choose on-grid if load shedding is rare and your main goal is a lower bill at the lowest cost. Choose hybrid if outages disrupt your home or business, or if you use a lot of power in the evening.
Under the 2026 net billing rules, exported units earn about Rs 10–11 while grid units cost about Rs 37–55, so using solar yourself, or storing it in a battery, is usually worth more than exporting it.
