Solar energy supplied about 2.3% of total US power in 2020, according to the US Energy Information Administration (EIA). While solar energy accounts for just a minor percentage of US power, that number is expected to grow.
You can help solar energy grow by installing solar panels on your own home.
Solar panel installation is fairly easy, but before you buy solar panels for your home, it’s important to know how many solar panels you’ll need to run your household.
In this article, we will look at some factors that will determine the number of solar panels you need for your home.
1. Energy Consumption in Your Household
The amount of solar panels you need depends on the amount of power your household uses.
You can determine the amount of power you consume by looking at the electric bill you receive from your power company. The solar panel size you need is measured in watts, so a good first step would be to estimate how many watts your household uses per hour.
You can then use that information along with the factors below to determine solar panels needed for your home’s solar installation.
The higher the amount of power you use, the more solar panels you’ll need to install.
2. Where You Live
This is the second most important solar panel sizing factor. Specifically, solar panels need more direct sunlight to be able to produce power.
If you live in a location with overcast skies or little sunshine throughout the year, your solar energy system will not be effective. Therefore, you won’t meet your household needs for power consumption.
To get an accurate picture of solar energy opportunities in your area, you need to look at solar irradiance data. This is a measurement of solar power availability for each location on Earth.
Solar irradiance varies with latitude and climate conditions, such as high altitude or distance from the equator.
Naturally, solar energy panels will be most effective when placed somewhere that gets a lot of sunlight throughout the year. If you live in an area with little sun exposure, you might need many solar panels to produce enough solar energy.
The better understand the effects of weather conditions on solar energy production, consider working with a local solar company.
3. Your Budget
Solar panels cost money. It’s important to know how much solar power you’ll need to determine your solar panel size and the overall price of installation. If you don’t have a large budget, smaller solar energy systems with fewer solar panels might be best.
However, if your budget is bigger than average and many solar panels would meet your household needs, go ahead with a larger system.
4. Solar Panel Performance
The solar panels you choose will also determine the number of solar panels necessary to power your home. The solar panel’s wattage rating is a measurement of how much energy it can produce in direct sunlight at 77 degrees Fahrenheit (F).
If solar panels have a larger wattage rating, they can produce more power in the same amount of time. This means you’ll need fewer solar panels to meet your household’s needs for electricity.
For example, assume solar panel A has a 150-watt (W) performance, and solar panel B has 300 W. Then, you might only need two solar panels from solar panel A instead of three solar panels from solar panel B to generate enough electricity for your home
Solar Panel Installation Simplified
Solar panel installation is a great investment for your home and the planet. However, it’s important to be prepared for solar panel installation by calculating exactly how many solar panels for home you need.
To determine solar panels needed for your solar energy system, take the factors above into consideration. Then, you’ll have an idea of how many solar panels are necessary to power your household.
