The 1.5 ton AC is Pakistan's most common household AC. To run it comfortably with load shedding backup, you need 6–8 solar panels and a 5kW–6kW hybrid inverter. Here is the complete guide — sizing, pricing, and the right configuration for your home.
A 1.5 ton inverter AC draws 1,100–1,400 watts when cooling at full capacity. With modern inverter ACs that modulate their speed, average consumption over 8 hours is closer to 900–1,100W. Combined with a fridge, fans, lights, and water pump, total home load is typically 2–2.5kW.
| Load Item | Running Power | Hours/Day | Daily Units |
|---|---|---|---|
| 1.5 Ton Inverter AC Main Load | 1,100–1,400W | 8–10 hrs | 9–14 kWh |
| Refrigerator | 100–150W avg | 24 hrs | 2.4–3.6 kWh |
| LED Lights (6 rooms) | 90W | 5 hrs | 0.5 kWh |
| Ceiling Fans (4) | 280W | 10 hrs | 2.8 kWh |
| Water Pump (0.5 HP) | 400W | 1 hr | 0.4 kWh |
| Total Daily Load | ~2–2.5kW average | 15–21 kWh/day | |
A 6-panel (3.9kW) system generates approximately 20–24 kWh on a good summer day — enough for all the above, with surplus to charge a 5kWh battery for evening and load shedding use. An 8-panel (5.2kW) system adds comfortable headroom for cloudy days and panel dust losses.
| System Configuration | Panels | Inverter | Battery | Installed Price |
|---|---|---|---|---|
| Basic — 1.5 ton AC + basics, no backup Grid power during load shedding | 6 × 650W = 3.9kW | Solis 6kW Hybrid | None | Rs. 550,000–650,000 |
| Saigal Starter Package Most Popular 1.5 ton AC + full home loads + load shed backup | 6 × 650W = 3.9kW | Solis 6kW Hybrid | Dyness 5kWh | Rs. 796,900 |
| Family Package — 1.5 ton AC + more panels More generation, better cloudy-day performance | 8 × 650W = 5.2kW | Solis 8kW Hybrid | Dyness 5kWh | Rs. 850,000–1,032,925 |
| Premium — 1.5 ton AC + extended night backup 10kWh battery — run AC through the night | 8 × 650W = 5.2kW | Solis 8kW Hybrid | Dyness 10kWh | Rs. 1,000,000–1,200,000 |
Prices include LONGi HiMo X10 panels, IP66 Solis inverter, Dyness LiFePO4 battery, GI mounting, DC/AC cables, DB box, MCBs, changeovers, and full installation in Faisalabad & Punjab.
Pakistan's most trusted panel. N-type TOPCon cell technology. 25-year linear performance warranty. Genuine LONGi — each panel's serial number is verifiable on the LONGi app. Higher efficiency means fewer panels needed vs older cell types.
IP66 dust and waterproof — better than IP65. Handles a 1.5 ton AC + full home load with headroom. Can accept up to 12kW of panels — start with 6, add more panels later. SolisCloud remote monitoring app. 5-year warranty. Official Solis distributor supply.
LiFePO4 chemistry — safest technology, no fire risk. 6,000+ cycle life (16+ years daily). 95% usable capacity. Provides 4–6 hours of backup for a 1 ton load (fans + lights + fridge + partial AC) during load shedding. BMS protection included.
GI C-Channel mounting for roof or ground. DC cable (4mm² copper), AC cable, MC4 connectors, DB box, MCBs, changeover switches, pipe fittings, 3-pit earthing system, all fuses and protection. Complete, code-compliant installation.
A 5kWh battery powering a 1.5 ton AC alone (1,200W) would last approximately 4 hours. But your total night load is not just the AC — you also have fans, lights, and a fridge. In practice, most Saigal Solar customers set their system to run fans, lights, and the fridge from the battery at night, keeping the AC on grid power (or off). This extends battery life to 6–8 hours.
For full AC-on-battery overnight, upgrade to a 10kWh battery — this gives 7–8 hours of AC + basic loads coverage.

⚡ Open the Solar Design Tool — FreeYes. A 6kW hybrid inverter can comfortably power a 1.5 ton AC (max 1,400W) plus all other standard home loads simultaneously, with capacity to spare. Even at 80% efficiency, a 6kW inverter delivers 4.8kW — well above a 1.5 ton AC's maximum draw.
Six panels (3.9kW) is the minimum for a 1.5 ton AC. Eight panels (5.2kW) gives 30% more generation — better performance on cloudy days, more battery charging time, and headroom for adding a second AC later. For most Faisalabad homes, 6 panels on a 6kW inverter is the sweet spot for value.
Both are excellent. Solis 6kW (IP66) is slightly more premium and the most popular choice at Saigal Solar. GoodWe ES 6kW (IP65) is a strong alternative with good local support. Both carry 5-year warranties and are compatible with Dyness and Pylontech batteries. Call us for a current price comparison.
Yes — a 6kW Solis inverter accepts up to 12kW of panels. Start with 6 panels today and add 2–4 more panels in year 2 or when you add a second AC. The inverter, battery, and all wiring stay the same. This is a common upgrade path for our customers.
