Quick AC Bill Answer
A 1.5 ton inverter AC used for 8 hours daily can consume about 312 units per month. At Rs 55 per unit, that is roughly Rs 17,160 before taxes, FCA, QTA, fixed charges, and arrears. A non-inverter 1.5 ton AC used the same way can consume about 432 units/month, or roughly Rs 23,760.

The solar impact number means this AC usage alone may require roughly 2.6kW of solar generation capacity under Bijli Hisab's Pakistan-average monthly generation assumption.

The simple formula is: watts x quantity x hours per day x days per month divided by 1000. For example, one 1.5 ton inverter AC using 1300 watts for 8 hours a day over 30 days is about 312 units per month.
1.5 Ton AC Bill Per Month in Pakistan
A 1.5 ton AC is one of the most common household loads in Pakistan. At Rs 55 per unit, an inverter 1.5 ton AC used for 8 hours daily can add roughly Rs 17,160 per month before taxes and adjustments. A non-inverter 1.5 ton AC can add more because its average running load is usually higher.

Inverter AC vs Non-Inverter AC Bill
Inverter ACs usually have a lower average running load when the room is cooled and the compressor slows down. Non-inverter ACs usually cycle at a higher fixed load, so the monthly units can be higher for the same hours. The difference becomes more visible in long summer usage, especially at 8 to 10 hours per day.
