The Physics of Running Inverter ACs on Solar in Pakistan
In Pakistani summers, air conditioning represents over 60% of total household electricity consumption. Modern DC inverter air conditioners employ variable-speed rotary compressors that reduce power consumption from 1,600W at startup down to 550W–750W once the room stabilizes at 26°C.

5–6 Marla homes running fans, lights, fridge, & 1 inverter AC. ~350–420 units/mo.
10 Marla homes running 2 Inverter ACs + household load. ~600–750 units/mo.
1 Kanal residences with 3–4 ACs & net-metering. ~1,250–1,500 units/mo.
Commercial plazas, schools, clinics, & large joint families. ~2,000–3,000+ units/mo.
Frequently Asked Questions (Solar Sizing & NEPRA Tariffs)
How many 580W solar panels to run one 1.5-ton inverter AC during the day?
A 1.5-ton inverter AC draws around 750W to 900W running continuously at 26°C. Factoring in startup surge and summer heat derating, a minimum of 3x 580W panels (1.74 kWp) is required per AC for daytime operation.
Can I run an inverter AC on solar without batteries?
Yes! With an on-grid or grid-tied hybrid inverter, you can run your inverter AC directly from solar panels during daylight hours, importing power from the grid only when clouds pass.
What battery is needed to run a 1.5-ton AC all night?
To run one 1.5-ton AC for 8 hours overnight (consuming approx. 6.5 to 7.5 kWh), you need a 48V 150Ah or 200Ah Lithium LiFePO4 battery bank (7.68 kWh to 10.24 kWh nominal capacity).
