Solar Air Conditioners

What is solar Air Conditioner?

This solar air conditioner works like conventional air conditioner. The two major differences is existing AC use only electricity grid and existing AC takes high wattage to run and solar AC is such designed that it takes very low wattage. “Solar air conditioner” has three options – 1st Solar power, 2nd Battery bank, & 3rdElectricity grid. Solar AC the MGM Technology (Compressor) works like an accelerator in a car. When compressor needs more power, it gives it more power. When it needs less power, it gives less power. With this technology, the compressor is always on, but draws less power or more power depending on the temperature of the incoming air and the level set in the thermostat. The speed and power of the compressor is adjusted appropriately. This technology is currently available only in split air conditione

What is benefit of Solar Air Conditioner?

This air conditioner will run continuously but will draw only that much power that is required to keep the temperature stable at the level desired. So it kind of automatically adjusts its capacity based on the requirement of the room it is cooling. Thus drawing much less power and consuming lesser units of electricity.

Features of Solar air conditioner:

Solar AC is a very effective solution for those locations where climate is hot & humid and grid based electricity is scare and unable due to frequent power cuts solar AC is designed to address these evident problems. Solar AC runs on different alternative energy sources i.e. when it is working on solar PV it saves and reduces Grid electricity demand, it is also very power efficient system and saves the electricity expenses of the customer. Solar ac is very environment friendly and it reduces grid power consumption t0 100% because the grid power is generated by Fossil fuel, whereas solar system reduces the grid power demand and the result in less carbon emission into the atmosphere.

  1. Can work without electricity
  2. Work on both, solar power and electricity grid.
  3. Solar air conditioner is Low maintenance.
  4. Zero electricity bill and saving 100%

Are Solar air conditioner slow in cooling?

Several people have concerns that Solar air conditioners do not cool well or cool slowly. However let us take this image as reference to understand how inverter AC works:

Regular traditional ACs are fixed speed ACs, where as solar ACs are variable speed ACs. Regular ACs have compressors that go “On” and “Off”. Whereas Solar ACs have DC compressors that are “On” all the time. As regular ACs are sized for peak summer heat load, they are over-sized all the other times (in fact most of the time people oversize even for peak summer season). The drawback of the same is that the AC “Over cools” most of the time. So if you set AC at temperature of 25, it will cool it down to 23 or 22. Now one would question: then what is the use of thermostat? Well the thermostat (in a regular AC) switches off the compressor when the outside temperature has reached 25. But a lot has happened before that. In an AC, refrigerant moves from liquid to gas (by taking heat from the room) and then back from gas to liquid as the compressor compresses it. But if the refrigerant is more and heat in the room is less (which happens in over sized AC), it does not get enough heat from the room to convert from liquid to gas and it keeps moving as liquid. Now when the thermostat detects temperature and switches off the compressor, the refrigerant still remains in liquid state and thus has capacity to take heat from room to convert to gas. And so it takes more heat from the room and cools the room below the set temperature.

In comparison, the Solar (MGM compressor tech) AC changes the flow rate of refrigerant based on the heat of the room. When heat is less, the flow rate is less, when heat is more, the flow rate is more. And it does not switch off the compressor ever. It just makes sure that if temperature setting is 25, it is maintained at that level.

‘E’ Model

This solar air conditioner is designed for urban/metro city where electricity cut is very less & where there is no space or roof for solar power plant and still need to save electricity bill. This Solar air conditioner is designed is such manner that you can save upto 80% electricity bill. This solar air conditioner is cost effective as no solar product are required to run this air conditioner. This solar air conditioner can be run directly to 220V AC and can save utpo 80% electricity Bill

‘S’ Model

“The rural areas and the Remote areas where there is heavy electricity cut off  or no electricity” for such are Solarway has designed a ‘S’Model Solar air condirioner. This Solar air conditioner can run directly on DC current or Directly through solar PV Module. This solar air conditioner can run directly through solar product in Day time and on battery in night time. This is a hybrid Solar air conditioner which can run on Solar product, Inverter battery and 200V AC.
