The average Malaysian household spends a substantial chunk of the power bill on air conditioning. The AC takes 11.9% of the bill, adding up to a hefty bill for the whole year. In this context, solar air conditioners promise substantial savings on the power bill. Unlike expensive solar equipment of the past, today’s solar air conditioner Malaysia installation is affordable and easy to install.
Conventional Air Conditioning units are powered by Alternating Current (AC), while off-grid power units are powered by solar energy. How can solar energy power air conditioning? The conventional way is to use a solar panel to harvest solar energy and store it in batteries. The power is drawn from the batteries and converted into AC power to power appliances, including air conditioning. The batteries and inverter make traditional DC solar powered air conditioners expensive.
But a modern solar air conditioner does not need inverters and batteries. A DC air conditioning unit can use power directly from the solar panels without an inverter or rectifier. This type of Air conditioner has an electronic frequency control, which varies the cycling of the AC for higher efficiency. This AC’s operation is flexible, which makes it more cost-effective than conventional AC.
The DC solar air conditioner is made to work with high efficiency modern solar panels. It requires lesser wattage than a conventional solar panel because there are no energy conversion losses. These losses occur when energy is stored, drawn, and converted by the inverter. A typical Li-ion battery has an efficiency of 90%, which means that it will utilize only 90% of the solar energy generated. Further heat losses can bring down the system’s efficiency to about 75%, depending on the configuration.
Is a solar air conditioner Malaysia installation worth it? The simple answer is yes. Solar air conditioners are now cheaper than before. You do not need to spend too much money on solar panels. This air conditioner also cut costs by eliminating the costs of an inverter and battery. This is crucial because these two components and their accessories take up almost half a solar energy system’s price.
Solar air conditioners may be a bit more expensive than conventional AC power air conditioners. But the savings on the power bill recoup these costs in a short time. The savings accrued after recouping the costs can be considered as profit.
The first step would be to know the wattage of the air conditioner you need. A typical three-bedroom house requires a 650-Watt air conditioner, while a four to six-bedroom house will require a 1600-Watt air conditioner.
The next thing would be to look at the usage of the air conditioner. How many hours is it in use per day? Consumption is calculated as kilowatt Hours. For example, if the 600W unit uses 6000 Watts in an hour, that is 6 kWh. If the air conditioner runs for 10 hours, the daily consumption should be 6kWhx10, -60 kWh. Multiply this number by the cost of electricity. If the price is RM 0.218/kWh, savings per day come to 60kWh X RM 0.218/kWh, which is RM 13.08.
You have to know the number of sun hours your area receives to help you get an idea of the solar panel wattage you need. These are the hours when there is sunshine enough to generate energy in the photovoltaic cells. To calculate solar panel wattage for an area with eight sun hours and a daily consumption of 60kWh, it will need 60,000/8, which is 7,500 Watts in solar panel wattage.
To calculate the rough estimate of solar panel costs, multiply the solar panel wattage by the present solar panel cost per watt. If the cost is RM 3 per watt, the cost will be RM 22,500.
Modern solar air conditioners are very easy to install because they are made for plug and play installation. The AC kit will fit easily into the existing energy system, whether AC or DC. A DC-power air conditioner is even easier to install because there are no inverters and batteries to configure.
It is easy to add a solar air conditioner into an existing solar energy system. The existing solar panels must generate enough power for appliances in the house plus the air conditioner. It may be necessary to add a solar panel to meet the added need for power.
A solar air conditioner Malaysia installation can help reduce household energy bills drastically while providing superior comfort levels in a home. Installing a solar air conditioner is also a service to environmental conservation because solar power is clean and sustainable.
