Solar panels are an excellent way to power your home, and they are becoming increasingly popular in the United Kingdom. However, when it comes to powering a fridge with solar panels, it can be challenging to know what size solar panel to install. In this article, we will discuss the factors to consider when choosing a solar panel for your fridge and what size would be best for your needs.
The first thing to consider when choosing a solar panel for your fridge is the wattage of your fridge. The wattage tells you how much power your fridge requires to function. The average fridge in the UK requires between 100 and 200 watts of power. However, this can vary depending on the size and age of your fridge.
Once you have determined the wattage of your fridge, you can use this information to calculate the size of the solar panel you need. To do this, you will need to take into account the amount of sunlight your solar panels will receive and the efficiency of the solar panel.
The amount of sunlight your solar panels receive will depend on the location of your home. The UK receives an average of 4 hours of sunlight per day, but this can vary depending on where you live. In general, the more sunlight your solar panels receive, the more energy they will produce.
The efficiency of the solar panel is also important to consider. The efficiency of a solar panel refers to how much energy it can convert from sunlight into electricity. The higher the efficiency, the more energy the solar panel will produce.
To calculate the size of the solar panel you need, you will need to use the following formula:
Size of solar panel = (wattage of fridge x hours of sunlight per day x 1.25) / (efficiency of solar panel x hours of peak sunlight per day)
Let’s say your fridge requires 150 watts of power, and you live in an area that receives an average of 4 hours of sunlight per day. If you have a solar panel with an efficiency of 15%, the calculation would look like this:
Size of solar panel = (150 x 4 x 1.25) / (0.15 x 4)
Size of solar panel = 1250 watts
In this example, you would need a solar panel with a capacity of 1250 watts to power your fridge.
It’s important to note that this calculation is just an estimate. The size of the solar panel you need will depend on several factors, including the efficiency of the solar panel, the amount of sunlight your solar panels receive, and the wattage of your fridge. It’s always a good idea to consult with a solar panel installer to determine the best size for your specific needs.
In conclusion, when it comes to choosing a solar panel for your fridge, the wattage of your fridge, the amount of sunlight your solar panels receive, and the efficiency of the solar panel are all important factors to consider. By using the formula above, you can estimate the size of the solar panel you need to power your fridge. However, it’s always best to consult with a professional to ensure that you choose the right size solar panel for your needs.
