Many people believe that the number of solar panels they would need for their household is determined by how much their house is big. But that is not true. The required number of solar panels is not calculated on the basis of the square of the house, but on the basis of current consumption. This is explained through the example:
Imagine two identical houses, which are exactly the same. Then imagine that in the first lives a man of 30 years, alone without a family. In the morning he goes to work, he returns in the afternoon. When he comes home he normally opens the refrigerator to eat something, showers and then turns on the TV. Always went to see her friends. In the house is rarely when cooking and storing food and besides TV. He regularly uses a computer and charger for the phone.
In the second house, there are a man, a woman, and three children. The man in the garage holds a workshop with many electrical machines that he uses daily, a woman keeps children and prepares meals daily, and besides a fridge, they also use a freezer for storing food, children use their laptops and the boiler is always on. From this story, you yourself see that the family consumes far more power than one man, although they all are living in two identical houses.
How many panels do you need?
How many solar panels do you need for a household depends on which devices you use and how often do you use them in the household – the size of the house is not important. On the basis of monthly electricity bills, you can see how much you spend an average on electricity, so the system is tailored to your needs. When you calculate how many solar panels your household will be needed, you can buy either that whole number so you can live free from an electric bill, or you can buy a smaller amount of panels which will help you lower your electric bill. Either way, your household will become more eco-friendly.
