What is Solar Power?

Solar power is usable energy generated from the sun. There are many advantages to use the solar power energy; not only save a lot of money, but also saving a lot of energy. In fact, the air conditioning produces 117 million metric tons of carbon dioxide to be released into atmosphere every year. Luckily, the solar powered air conditioner can help you. It is a great way to save the energy cost and also reduce the release of carbon.

What is Solar Powered Air Conditioner?

  • Solar powered air conditioning system means the air conditioner is powered by the electric generated from the sunlight. There are two different solar powered air conditioners, solar PV air conditioner and solar thermal air conditioner.

Solar PV air conditioner

PV means solar photovoltaic panels. The solar PV air conditioner is powered with the solar energy generated by solar panels. It is the most common solar powered air conditioner.

Solar PV air conditioner

Solar Thermal Air Conditioner

Solar thermal air conditioners use solar collectors to heat a liquid, for example, water. The evaporation and condensation of the water in the system produces the cool air for your home.

Solar Thermal Air Conditioner

Why We Need Solar Powered Air Conditioners?

Save money

Although solar powered air conditioners are substantially more expensive than a traditional air conditioning unit. However, the solar AC will save a lot of energy bills over the years and it rapidly offsets the upfront cost.

Easy to maintain

The solar panels on the roof do not require extensive maintenance. As long as it rains a few times during the year, your solar panels will receive all the washing and cleaning they will ever need.

Help the environment

Solar energy is a green energy source and reduces greenhouse gas emissions. It also reduces the demand on electric grid.

What‘s the difference between 100% Off Grid & AC-Powered & Hybrid Powered Solar Air Conditioners?

100% Off Grid DC Solar Air Conditioners

Different from the conventional air conditioners, 100% off grid DC solar air conditioner uses the BLDC compressor, generally it uses 48V dc air conditioner compressor, like JVSA116Z48 or JVSB180Z48. It is powered by direct DC electricity or batteries. The solar photovoltaic panels convert the sunlight into electric, and storage in the batteries. Then the DC solar air conditioner runs through the batteries.

AC Voltage Powered Solar Air Conditioner

The hybrid solar-powered air conditioner is a mixed solar AC/DC air conditioner, which can run on both DC and AC at same time seamlessly. It can be connected to both the solar panels and batteries directly and to the grid at same time. The unit can use the appropriate power source according to the time of day and power load. If low sunlight or in the night, the unit can use the power source from grid.

Hybrid Powered Solar Air Conditioners

The hybrid solar-powered air conditioner is a mixed solar AC/DC air conditioner, which can run on both DC and AC at same time seamlessly. It can be connected to both the solar panels and batteries directly and to the grid at same time. The unit can use the appropriate power source according to the time of day and power load. If low sunlight or in the night, the unit can use the power source from grid.

What are the main components of 100% Off Grid DC solar air conditioner?

Can we run an RV air conditioner with solar power?

  • Yes, it is technically possible to run RV air conditioner with solar power. It is even possible to power the largest cooling capacity RV air conditioner.
  • If your air conditioner is a non-inverter RV air conditioner, an inverter will be needed to power your RV air conditioner if use solar power. The function of the inverter is to transform 12V voltage to 220V or 115V voltage.
  • If your air conditioner is a 12V RV Air Conditioner, then the inverter is no needed. It is drived by 12V batteries directly, and no need to plug into 220V system or 110V system.
