Can a low car battery affect the air conditioning?
Faulty Car Electrical System. A weak car battery can cause your auto air conditioner to function poorly or not at all. Car batteries need to have enough voltage to trigger the AC compressor, and while it may be strong enough to run the rest of your car, it may still be too weak to run your car's air conditioning.
Depending on the tonnage of the AC and heat load in a room, an AC would consume about 1 to 2 units of electricity in an hour. A 1 kW Solar PV Panel would produce about 5-7 units in a day, which can get consumed in 4-5 hours of continuous running of an air conditioner.
- Instead of putting in another 6 KW of solar power on your roof to power a traditional energy guzzling air conditioner, take a look at a completely different kind of air conditioner to go with your solar installation: The Coolerado can cool 3,000 square feet with just 600 watts of power; or just (depending on watts) 3
- To make up a 2kW Solar System you need 8 solar panels, assuming that you use 250W panels. Each panel will be about 1.6m x 1m, so you'll need at least 13m2 of roof space. And here's a picture of a 2kW solar system on a roof (made up of 12 x 165W solar panels).
- To make up a 10kW Solar System you need 40 solar panels, assuming that you use 250W panels. Each panel will be about 1.6m x 1m, so you'll need at least 64m2 of roof space.
But rough estimates for how many watts an air conditioners uses are; Central Air Conditioner – 3500 Watts. Central A/C Fan Only – Compressor Off – 750 Watts. Largest Window Units – 1440 Watts.
- The average reverse cycle air conditioner costs around $0.25 – $0.35 per hour to run for cooling purposes, depending on the size of the room. A medium sized room of 36sqm would cost $0.36 – $0.70 per hour to run. In large areas (50sqm), it will cost between $0.70 and $0.95 per hour.
- (Dividing by 1,000 changes watt-hours to kilowatt-hours.) For example, in this case the mathematical formula looks like this: 550 x 24 ÷ 1,000 x $0.12. The cost to run a 5-amp, 5,000-Btu air conditioner over a 24-hour period is about $1.60.
- An average central ac will use 3000 to 5000 watts of power every hour for around 9 hours a day during the hotter months. Click calculate to find the energy consumption of a central air conditioner using 3500 Watts for 3 hours a day @ $0.10 per kWh.
