Installation of solar systems for Ten Air Conditioners is becoming a more favorable choice as both are preferred for sunny weather. But it needs a decent solar system to run the massive load of 10 air conditioners. The power rating of a standard Air conditioner is around 1800W or 1.8kW. To run an air conditioner for 24 hours, it also needs a storage system at a large scale. To determine the suitable solar system for usage, calculate How many kW solar systems are required to run 10 two-ton air conditioners for 24 hours.
Here is the Calculation
Required wattage: Power rating of air conditioner * No. of Air conditioner = 1800W * 10 = 18000W or 18 kW
Total Power Required per day: Required wattage * Working hours of appliances = 18kW*24 Hours= 432kWh or 432 unit of electricity.
Now, we have a daily power requirement. Typically, a 1kW solar system can produce 5-6 units daily during sunshine. To meet the demand for 432 units, over 72kW solar system is tolerable. But if we include energy loss, we need a 75kW solar system for the same unit production.
Q- How many solar panels and batteries would I need to run 10 two-ton AC for 24 hours daily?
A- By this blog post you can get a close estimation value of how many kW solar systems are required to run 10 two-ton Air conditioners for 24 hours daily. The no. of solar panels and batteries need depends upon the size and efficiency of solar panels and batteries respectively.
For example- a 75kW solar system has around 150 solar panels of 440 - 530 watts. And to get the nos. of battery, it needs a small calculation - subtract the units utilized during sunshine from the daily energy requirement.
daily energy requirement: 432kWh
Average Sunshine duration: 6 Hours, which means a quarter of the day or 24h/6h= 4 (period of sunshine per day).
units utilize during sunshine: daily energy requirement/ period of sunshine per day= 432kWh\4= 108 Units
size of battery required = units utilized during sunshine - daily energy requirement
=432-108= 324 kWh battery is sufficient for backup for around 18 hours and 65 nos. of 5kW lithium battery (Due to the ability of fast charging) is required.
Q- How much area is needed for 75 kW solar system installation?
A- The Area of installation requirement varies to types of the solar system and solar panels, For estimation SHARK Bi-Facial Solar Panel, 440 - 530 Watt required 24 sq.FT area per panel.
Q- Why lithium battery?
A- Lithium battery has a comparatively high advantage over any other batteries in the market like
- High efficiency and storage capacity
- fast charging
- Long lifespan and fine durability.
