# How Many Solar Panels To Power A House?

04/20/2022

Before you need to buy solar panels, there are many things you need to know, for example, the quantity of solar panels, power, and quality of solar panels. When you need to use them to power your home electrical appliance, then you need to know how many solar panels you need to buy. here, in this post, I would like to give you some instructions. please continue to read...

Solar energy is limitless on our planet. We can never run out of them even if we use them all the time. Our solar system is particularly important as it nourishes and sustains all kinds of living beings on earth. Humans have since used the sun to give directions, keep track of time, and provide humanity with energy for many years.

More and more homes use the sun as their energy. According to ancient research, Egyptians were the first civilization to use solar energy to power their homes. It is still unclear how ancient people could store the sun’s energy and power their homes at night.

For some time, nonrenewable energy sources have contributed to carbon emissions and have been depleting very rapidly. Many homes and organizations are now encouraged to use renewable energy sources to run their day-to-day activities.

The number one source of renewable energy that has been thought to be helpful is the sun, and many homes are using solar energy to run their daily lives, and there is one excellent reason why they use solar power.

## How to Calculate The number of Solar panels Needed to Power A House?

To get the same power required to power a home, you will need to consider several things like the amount of energy the house will consume, the number of people in that house, the house’s direction, and the house’s size to be calculated. The state you reside in will also play a factor in knowing the number of solar panels to install.

Houses in cities where more sunlight is received will need a smaller number of solar panels, and houses in cities that review less sunlight will need more solar panels. Let us have an example of South Carolina or Alaska that receives less sunlight and will need to install many solar panels compared to California, a Sunny state.

You should know the amount of sunlight your area receives to calculate the number of solar panels that need to run your house 100 percent. Recent studies have shown that 10,164 kWh of energy is used in a single household in America per year.

Let us divide that by 12 months to get the monthly consumption. That gives you 847 kWh per month. Let us now divide 847 by 30 days and see how much is spent per day. You will get 28 kWh daily consumption.

Now let us divide that by the sunlight peak hours received in each city. Let’s give an example of California, which receives 9 hours of sunlight per day. Let us now divide the daily consumption by the number of hours in one day. That gives you 3kWh. All solar panels come in watts, so we need to multiply 3kWh by 1000 to get the watts.

That gives you 3000 watts. If we assume that we are using the 72 cells 350-watt solar panel, we will need to divide 3000 watts by 350, which gives us 8.5, which is roughly 9. That will mean that you need nine solar panels to power your house in a day that your area receives perfect sunny conditions.

## How Solar Energy Works

Trying to understand how solar panels work is quite impressive. So how do solar panels work? Solar power inverters are the answer. The 600w solar panel captures sunlight and converts it into Direct Current (DC).

You cannot use that direct current in your house, so the inverter is needed to convert direct current and Alternating Current (AC), which is used to run appliances in your house. You should, however, look for brands and types of inverters before buying one for your installation.

## How Much Energy is Produced by a Solar Panel?

Before we even start on how much electricity a panel produces, we must know which types are available. Two types of solar panels are available in the market today. Polycrystalline and monocrystalline.

They both work and operate differently. The monocrystalline solar panels are the best when it comes to efficiency. They operate well in shady conditions, work well in high heat, and consume sufficient space.

But you still need to know, they are costly, but you will have many years of free solar energy once you get one. They are darker in color and are made of silicon cell slices. They have a long lifespan compared to other solar panels.

In addition, polycrystalline solar panels are cheap, and they do not have a long lifespan compared to monocrystalline panels. They use multiple melting cells and are lighter in color. They do not work well under high temperatures and are low inefficiency.

## Conclusion

From what we mentioned above, the quantities of solar panels are decided by many factors, just like weather, location and the quality of solar panels. In my opinion, you had better ask your installer about how many solar panels do you need to power your whole house.
