After talking about how you can cook outfield using solar power cooker, I'm going to introduce you another great invention to allow you to go greener. You can use this amazing product together with your solar cooker outdoor! It'll totally change the way you go camping forever. This device is – Solar Powered Refrigerator!
Solar powered mini refrigerator, also call solar powered freezer is another way you can use solar energy to improve your life. Many great products are invented to go green, using free solar energy to replace electricity. Usually people tend to get a solar powered mini refrigerator due to the size. They do not need a huge refrigerator and it's too bulky to bring out. A small, compact fridge will solve this problem, plus it's cheaper.
Solar Refrigerator How It Works
Back to the basic question – how does a solar refrigerator works? I guess lots of people are wondering. Well, the answer is … there's no different! The fundamental is still the same, be it a normal kitchen fridge or a solar powered fridge. Both use the refrigerant, let's say – Freon to cool down the temperature.
Freon is constantly flowing throughout the refrigerator to cool it, and it's in liquid form. Once the temperature inside the fridge rises, the freon will absorb the heat and change to vapor. The vapor moves into a compressor which will compress the vapor and cool it back to liquid state, and this goes on.
What's consuming lots of electricity and power is the compressor. It is working 24 x 7 non stop and it is powered by electricity. The difference between solar powered refrigerator is that the compressor is powered by batteries. These powerful lead batteries will be charged in the day, and continue to function at night.
Advantages of using Solar Refrigerator
So what are the advantages of getting a solar fridge? Not only it is portable, you can fit to anywhere you want. I have once fit my solar fridge inside a RV before going for a long tour. In the day, I just bring it out to charge. At night, I can enjoy the cold beer, listening to music and enjoy life.
Long term saving is the main benefit. Most of my friends who purchased a solar refrigerator was to save money. Let me say this upfront. A good solar fridge doesn't come cheap. However, you can use it for a very long time. It'll work like a normal household fridge and you'll need not pay a single cent on the bills anymore.
Thirdly, which I personally find it is the most important reason, is to save the Earth. I'm writing this blog to show people how they can do their part to save our dying Earth. I believe the people want to do their part, just that many of them do not know how to do it. There are so many solar devices around and I want to create awareness to the world. Start using solar energy, go green today
Disadvantages of using Solar Refrigerator
Despite having many advantages, I'll reflect truly about the disadvantages of solar refrigerator. The biggest headache is the lead batteries. They are heavy, comprises of lead acid which will deteriorate after several years. Once the batteries gone bad, you have to get them replaced, which incurred additional costs.
Other than that, there's no need to maintain the solar fridge. Just leave it in the sun, and it'll serve your for years
Solar Refrigerator DIY Kit
If you want to maximize your solar refrigerator's life, you can integrate Solar Parabolic Cooker's
method to make it more effective. That is, keep the fridge under shade. Do not put it under the blazing sun. This will degrade the batteries and fridge fast. Instead, use mirrors or reflective materials to reflect the sun's ray to the solar panel.
You have to adjust the mirrors once a while to face the sun. This can be troublesome, but if you setup well, your solar fridge can last many years more.
Another method is to rewire the solar panel. Some of my friends setup the solar panels outdoor, while leaving the solar fridge inside the house. They hook it up to a long wire. This is much more convenient. However, you do have to check if the batteries are charging regularly. There may be poor contacts due to bad connections of wires.
