20kW solar system price
A 20kW system has four main costs: the panels, the inverter, the structure and the installation (cables, breakers, earthing and labour). A hybrid system adds batteries, which is usually the biggest extra cost.
Panels: 32 × Astronergy 625W N-Type Bifacial Panel at Rs 27,188 each comes to Rs 870,016 at today’s price.
The inverter, structure and installation depend on your roof and the brands you choose, so we quote them after a free survey. See current inverter prices and battery prices.

Frequently asked questions
How many units does a 20kW solar system produce?
In Lahore, a 20kW system produces about 79.6 units a day on average, or around 2,420 units a month. Output is highest in May (about 3,199 units) and lowest in December (about 1,600 units). Shading, dust and panel direction change these numbers.
How many solar panels are needed for a 20kW system?
With 625W panels you need 32 panels, giving 20.00 kW. With smaller panels you need more of them.
What is the load capacity of a 20kW solar system?
On a sunny day a 20kW system can typically run: four to five inverter acs; 1–2 kanal homes with heavy summer loads; schools, offices and showrooms. Peak output is lower than 20kW in practice because of heat and losses, and after sunset you need the grid or batteries.
What is the 20kW solar system price in Pakistan?
The price depends on the panel brand, the inverter (on-grid or hybrid), batteries and the structure. At today's price the 32 panels alone cost about Rs 870,016. A complete on-grid system costs less than a hybrid one because it has no batteries. We give an itemised quote after a free site survey.
How much roof space does a 20kW system need?
Roughly 1,200 square feet of shade-free roof, including walking space between rows. An elevated structure lets you keep using the roof underneath.
Is a 20kW system on-grid or with battery?
Both are possible. On-grid (with net metering) gives the lowest price and fastest payback; hybrid adds batteries for load shedding. Which one suits you depends on your bills and how much backup you need.
