With air conditioning, you have to spend a lot on electricity bills. So, it makes sense to switch to solar since it saves a lot of money, especially during long days. Even though you might not have seen one, solar-powered air conditioners are very common.
Solar Air Conditioning
There are two types of air conditioning systems:
Whole-home Solar Power & Air Conditioning Systems:
These units are pretty much visible since they are installed within the property. They cool specific areas. Whole-home solar set-ups can easily replace utility electricity, usually utilised to run portable AC appliances or HVAC systems.
Independent Solar Thermal Air Conditioning Units:
They don’t need another system and can easily use refrigeration and solar heat collectors to reduce the temperature.
The Working
Solar-powered air conditioners have three types of operation:
Solar Thermal Air Conditioners:
These capture energy from the sun and transfer it wherever it’s needed. Usually, the energy is used to evaporate a refrigerant fluid. These air conditioners work best when assisted by an electric-powered fan to distribute cool air in an area efficiently.
Direct Current (DC):
It can operate on the current that is coming from the solar panels without the need for an inverter.
Alternating Current (AC):
In this case, a solar inverter is needed to convert DC to AC so that this air conditioner can operate.
Although they are not used much for residential use, solar thermal air conditioners are available in varying capacities and forms.
AC and DC Air Conditioners
Most individual cooling appliances and air conditioners operate on AC. However, an inverter generates direct current (DC) solar power, which needs to be converted to AC. These energy systems can be a battery backup for off-the-grid users and store electricity as DC power.
With no need for conversion, this stored energy can be used for maximum efficiency in times of need. A DC air conditioner is ideal when you need peak power and efficiency. On the other hand, AC air conditioners make it easier to generate electricity to keep specific areas cool.
The Number Of Solar Panels Needed
The number of solar panels needed depends on a few factors:
- Amount of annual sunlight received by your home.
- Overall energy consumption.
- Efficiency and energy output of one solar panel.
The least you need is a rooftop solar panel system that generates enough energy to match the power consumption of your air conditioner.
The Advantages
- Using solar is good for everyone since it is renewable and has a low carbon footprint.
- Solar energy systems will save you money which otherwise would’ve been spent on electricity bills.
- You can keep running your system worry-free even if utility rates are high or there is a blackout.
- You can be exempted from specific tax incentives and even reduce upfront costs if you own a solar air conditioner. However, you have to check your state’s rules for this.
Conclusion
In short, if you want to reduce carbon emissions, save on bills, and live a generally worry-free life concerning air conditioners, you should invest in a solar air conditioning system. It is the best way to cool your home and not feel guilty or worried about anything.
