Solar power air conditioners utilize the power stored in the sun by using photovoltaic cells (PV panels) to convert sunlight into AC electricity. These units run on small batteries that must be periodically charged with a small amount of electricity. It can take from eight to sixteen hours to charge the batteries to full capacity. Once fully charged, these batteries will power up the solar panel and the AC motor within the unit. Solution and service by Deye - famous China Solar Air Conditioner Manufacturer.
