7kW Solar System Price in Pakistan

What a 7kW solar system can run

In strong daytime sun our 7.5kW packages run up to three 1.5 ton inverter ACs at partial load, a fridge, a deep freezer, a 1.5 HP pump, 8 fans and 20 LED bulbs. A washing machine is fine when one AC is off. Thirteen panels make about 28 to 34 units (kWh) on a normal sunny day, or roughly 900 to 1,000 units a month as a yearly average.

The inverter is rated 6kW, so it, not the panels, limits how much runs at once. Keep the total running load under about 5 to 5.5kW. The extra panels mean the system reaches useful power earlier in the morning, holds it later in the afternoon, and copes better with haze and dust.

7kW lithium vs 7kW tubular package

• Lithium (7.5kW Solar System with 7kWh Lithium Battery (Single Phase)): two Pylontech US3000C batteries (7kWh). About 90% is usable. Expect about 5.5 hours at a 1kW night load, or about 3.5 to 4 hours with one AC. No water and long cycle life.
• Tubular (7.5kW Solar System with 4 Tubular Batteries (Single Phase)): four AGS SP-250 batteries (about 8.4kWh). Using about half gives about 3.5 hours at 1kW, or about 2 to 2.5 hours with one AC. It needs water top-ups, space and ventilation.

At this size the lithium version gives noticeably more night backup. Other differences are maintenance, weight and how long the battery lasts. Lithium is rated for thousands of cycles. Tubular often lasts around 2 to 3 years under daily deep cycling in Pakistani heat.

7kW solar system price in Pakistan: what you get

The 7kW solar system price covers 13 panels, the 6kW inverter and the battery set. Live prices for both versions are shown on the package cards.

Both packages are off-grid hybrid systems on a single-phase connection. They use grid power when needed but do not export, so they are not used for net billing. If you have a three-phase connection and want export, look at the 10kW packages (10kW Solar System), which use a Deye on-grid hybrid inverter. The single-phase solar system page (Single Phase Systems) lists every package that suits a single-phase meter.

Is 7kW the right size?

Choose 7kW if your home has two or three ACs, a bill of roughly 700 to 1,000 units a month, and roof space for 13 panels (about 34 square metres plus walking space). It suits most 10 marla homes and many 1 kanal homes that do not run all ACs at once.

To check your own load, use the solar calculator (Solar Calculator) or the solar load calculation guide (Solar Load Calculation: Find the Right System Size).

If you mostly run two ACs and rarely use a third, the 5kW packages may be enough and need less roof space. If you plan to add ACs over the next few years, 7.5kW gives more room.
