AIR CONDITIONING POWERED BY THE SUN: MYTH OR TRUTH?

Due to the high temperatures people seek alternatives to cool off, but with the current shortage of water and their respective fines, options such as swimming pools and lengthy baths are off the list. Besides, these are temporary options to freshen up.

To resolve this issue the vast majority of the population chooses to buy air conditioning or fans, and that creates another problem: the electric bill.

As energy prices are rising too much and the heat remains strong people have searched for “air conditioning powered by the Sun.” Below 3 Myths and truths:

The air conditioning can be moved only with photovoltaic solar energy?

Truth: To have an air conditioner moved only to solar energy, it is necessary a lot of solar panels and many batteries (So you can) but this makes the high cost and to a common home the financial return is too long. In situations where you do not have access to network and need to use a diesel generator this solution becomes economically viable. (example fishing boats)

The air conditioning can be moved only with photovoltaic solar panels?

Myth: the air conditioning needs a stable supply of energy. If the day is cloudy or rainy the energy generated by the solar panel may not be sufficient for the air-conditioning work.

The LG has a Solar air-conditioning?

Truth: Though this model is not available in Brazil yet. He has a small solar panel that only produces 70Watts 3.5% of energy that air-conditioning consumes (this model consumes around 2000Watts). The LG has a lot more to show the brand’s commitment to sustainability than solve the issue of energy consumption of air conditioning.

There are some other solutions being developed to reduce the energy costs of air conditioning using solar thermal (solar heating). Such equipment using heat exchange pumps and are practically nonexistent in Brazil until then (save rare exceptions).

Therefore the best way to use solar energy in Dubai to power an air conditioner is the installation of a photovoltaic system connected to the network.

For companies and businesses that operate during the day, it’s a perfect solution: When the day is very warm and sunny you’re producing enough energy with solar panels and this energy is used to power the air conditioner. If you happen to spend a very large cloud and lessen your solar energy production has no problem because, you’re still connected to the network and that your Panel is unable to provide the distributor network provides.

 Even if you use air conditioning at night, when there’s no sun, no problem because you generate excess energy during the day and this energy goes to the distributor network and generates energy credits that are used to shoot down your consumption at night (see How does photovoltaic system). This way you can use and abuse of your air conditioning without worrying so much about the electric bill!
