An inverter takes DC power from the battery and supplies AC power … So, if you decide to power an air conditioner or try and break-even on a ASHP, it is going to use up the vast majority of your solar energy. Battery along with a charge controller would make the entire solar panel system energy self-reliant. Even still, a 10kW installation isn’t really that big and is a fairly common installation size. ), Value of current required = 221.04/4= 55.26 A. You simply divide the power AC required by the sum of wattage of total solar panels. Different stars ACs have different ratings that are following; We will consider here 5 star AC, whose Energy Efficiency Ratio (EER) is equal to 3.1. It depends on the air conditioner and how much power it needs. Home » Solar Panels » How Many Solar Panels to Run an Air Conditioner. However, in another word: maybe. Question: Estimate the monthly cost of 1 Ton AC that runs for 3 hours daily, If the bill is charged at $0.05/kWh.
