Now more and more people pay attention to the energy saving solution, when they buy the home air conditioner, refrigerator and so on. How to create the more energy saving air conditioner? It has been one of the most important directions of the air conditioning industry. Compared with thermal power, the solar energy is the most valuable new energy. So the question is, “Is solar powered air conditioner energy saving?” The answer is” YES, definitely.”
What is a solar powered air conditioning system?
The solar powered air conditioning system, just as its name implies, the air conditioning system uses the electricity from solar power .The solar panel converts the solar energy into electricity, then stores it in batteries through the solar charge controller.
The solar powered air conditioners are divided into AC powered solar air conditioner and DC powered solar air conditioner.
The AC powered solar air conditioner uses the AC power compressor. You will need an inverter to convert the DC voltage to AC voltage to drive the air conditioner.
The features of AC powered solar air conditioner:
- The cost of ac powered solar air conditioner is lower than dc powered solar air conditioner.
- It needs an inverter to convert the DC voltage to AC voltage, so there is power loss during converting.
The DC powered solar air conditioner uses 48V DC compressor. The 48V dc compressor is dc rotary compressor. So the solar air conditioner is powered by DC power or batteries.
The feature of DC powered solar air conditioner:
- The cost of dc powered solar air conditioner is higher than AC powered solar air conditioner. But it only takes one to two years to recover the purchasing cost of the solar air conditioner. The solar air conditioner can help customers save the electricity as long as they use it.
- It no needs the inverter, so there is no power loss compared with AC powered solar air conditioner.
- The DC powered solar air conditioner widely used in remote mountain villages, islands and other places without electricity or the electricity is not enough.
Which is more energy saving, AC powered solar air conditioner or DC powered solar air conditioner?
The DC powered solar air conditioner is more energy saving. Because it uses the 48V dc air conditioner compressor, the solar air conditioner with 48V dc compressor is powered by the electricity from the solar panels directly, without any power loss.
The AC powered solar air conditioner needs an inverter, there is power loss when convert the DC power to AC power. So the dc powered solar air conditioner is more energy saving.
What does the solar air conditioner consist of?
The AC solar powered air conditioner consists of solar panels, solar charge controller, batteries, inverter, indoor unit and outdoor unit.
The DC solar powered air conditioner consists of solar panels, solar charge controller, batteries, indoor unit and outdoor unit. The DC solar powered air condition no needs an inverter.
What kind of compressor use in the DC powered solar air conditioner?
The DC powered solar air conditioner uses the 48V dc compressor. The 48V dc compressor is dc rotary compressor, it also called bldc compressor, brushless dc compressor, dc inverter compressor. The 48V dc compressor uses an electronically commutated permanent magnet brushless DC motor, so it requires the use of drive, to drive the compressor.
We are the earliest manufacturer focusing on the R&D, production and sales of the dc compressors in China, now we have full series of DC12V, DC24V, DC48V, DC72V, DC312V dc rotary compressor for your selection.

How many panels will I need?
It depends on the output power of the air conditioner and solar power generation system. The solar power generation system consists of solar panels, solar charge controller and batteries. In order to provide the enough power for the air conditioner, it is necessary to choose the reasonable part according to the power of the solar air conditioner.
The following is an example of using 100W output power of 6 hours a day:
First of all, calculate the power consumed every day (Watt-hous). If including the inverter, so the loss of inviter should also be calculated.
Without inverter: the output power is 100W, if it is used for 5 hours a day, the output power is 100W*5 hours =500Wh.
With inveter: The output power is 100W, If the coversion efficiency of the inverter is 90%, the actual required output power should be 100W/90%=111W; If it is used for 5 hours a day, the output power is 111W*5 hours =555Wh.
Calculate the solar panel: according to the effective sunshine time of 6 hours per day, and taking into account the charging efficiency and the loss during the charging process, the output power of the solar panel should be 555Wh/6h/70%=130W. (70% is the actual power used by the solar panel during the charging process).
