Love it or hate it, solar is here to stay. Let’s examine what solar energy actually is and how it might help you. Here is a brief synopsis of it. PV, short for photovoltaic, is a type of solar energy that, like photosynthesis, gathers energy from the sun. Naturally, DC power is extracted from solar energy, but AC power is what we often utilize in our homes.
Due to its high voltage, AC power is potentially very lethal, and because of this, the majority of AC-powered product manufacturers use it inefficiently. This is the main cause of solar application issues in homes. The majority of consumer goods require a lot of electricity when switched from DC to AC. Even the conversion process itself loses energy. As a result, DC devices were created to benefit from the lower voltage and higher efficiency possibilities.
For instance, you can be energy conscious by unplugging and turning off everything that is not necessary in order to save electricity. What remains that you are unable to switch off? Yes, your freezer and/or refrigerator! Unfortunately, because they operate on AC (as opposed to a solar refrigerator, which operates on DC), they consume a significant amount of energy and must be kept running in order to keep your food fresh. Here are a few more significant benefits of owning a solar freezer.
1.You Develop Blackout Resistance
Everyone has their air conditioners running at full capacity because it is a hot summer day with considerable humidity. Rolling blackouts can occur frequently in certain weather conditions, such as a rain storm with damaged power lines. Most of the time, you’ll be able to survive without power for anywhere between a few hours and a week, but what about the hundreds of dollars worth of food in your fridge and freezer? You won’t experience this issue once more if you have a solar freezer. As long as the sun is shining, they run on their own. You draw energy from the sun’s UV rays even when it is obscured by clouds. Your refrigerator is powered by a battery bank that is charged by the sun. Solar freezers are made to operate flawlessly day or night, all year long, independent of the electrical grid.
2. Greater Efficiency in Energy
Why not simply use a solar panel to make your present energy-efficient refrigerator function similarly? It’s because solar refrigerators were made to run as efficiently as possible. Instead of converting the power back to AC power, solar refrigerators are wired and powered by DC power. In other words, all you typically need to run a solar fridge is two 140-watt panels and two 100Ah batteries and a charge controller, unless you are powering an AC hybrid freezer meaning you would need an inverter and two 140-watt panels for your solar system. An AC fridge can require up to three to six times the panel capacity of a typical refrigerator of equal size to supply the initial burst of electricity needed to start the compressor. In summary, a solar refrigerator will only need two 140-watt panels and two 100Ah batteries, compared to up to six batteries, additional solar panels and an inverter for an AC refrigerator.
3. Higer Level of Safety
Most people agree that one of the safest ways to produce electricity is through solar. In line with this, solar refrigerators often run on 12v/24v voltages rather than higher, potentially harmful voltages. One of the main benefits of this is the possibility to connect a solar refrigerator to a PV system that already exists or to a system that you are establishing with it without the risk associated with working with voltages higher than 24 volts; in contrast, a 12-volt refrigerator is very safe. Other options for the solar refrigerator include burning fossil fuels, which will pollute the air and release greenhouse gas emissions, or using higher voltages like 110v or 120v, which are lethal to humans. There is no need to be concerned about things blowing up, hazardous leaks, or lethal electric shocks that go along with conventional alternatives to solar refrigerators.
4. Plug and Play
Installation is as easy as connecting the solar refrigerator to your batteries if you already have a solar system. Otherwise, if you are just setting up your solar system, you only need to make sure that your panels and charge controller are connected after connecting a solar refrigerator to your batteries. Your solar refrigerator will then run on its own, so you won’t have to bother about turning it on and off, changing the fuel, or maintaining it. Want to put a solar fridge in your cabin and go on vacation for a week, month, or year? No issue. In the event that there is no sunlight for several days, the two batteries make sure that energy is conserved so that the solar fridge continues to operate and your food is kept fresh.
5. Operation for Free
Your new solar appliance won’t set you back any money. The energy produced by a single panel powering a solar refrigerator is much greater than the energy used by the refrigerator. The compressor in the fridge must first start-up, which uses the majority of the power. Once it is operational, the operating power drain is incredibly minimal. The solar refrigerator does require an upfront investment, but there are no additional fees or required fuel purchases. Depending on your system, you might not need any additional panels or batteries if you already have a solar setup. If you are new to solar energy and you are satisfied with the results, you can upgrade your system after making the initial investment and move even more aspects of your life off the grid. For example, if you have some solar panels on your RV, your DC refrigerator can even function as an RV refrigerator. Your solar refrigerator will last for years if you take good care of it. Spend the money you save on utilities on something you like to do.
6. Solar Fridges/freezers are Eco-Friendly
Burning coal is undoubtedly the most popular and least expensive way to produce energy. We also need to wean ourselves from nuclear, which has a strong priority in society. Our used fuel rods would be properly disposed of if it was safe to do so. Any means of reducing the amount of energy we draw from the grid would lessen our dependence on burning coal and other fossil fuels as well as our need for nuclear power. Using solar energy affects our environment both directly and indirectly. A solar fridge, like many other solar products, will use less energy than alternatives, many of which have negative environmental implications, whether it is used on or off the grid.
