How Many Solar Panels Does Your Roof Need?

Did you know that America uses 95,209 solar capacity based on a worldwide survey?

As more and more people are becoming aware of the benefits of clean energy and as the cost of installation goes down, it makes more and more economic and environmental sense to adopt solar as a source of electricity generation.

Solar energy systems have gotten much more compact, easier to install, more efficient, and more affordable than they have ever been in the past.

Are you then interested in finding out all about solar panels and how many solar panels you’ll need for your roof?

Look no further than our guide!

The Amount of Sunlight

You can determine how many roof solar panels you need by figuring out how much sunlight your roof gets. Example: Say your roof gets 4 hours of direct sunlight per day. In a year, that would be 1,460 hours of sunlight. If you have a 1 kilowatt (kW) system, that roof will get you 1,460-kilowatt hours (kWh) of energy per year.

The Size of Your Roof

This is a difficult question to answer without knowing the size of your roof. A general rule of thumb is that you will need about 100 square feet of roofing space for each 1 kilowatt (kW) solar power you want to generate. This means that a 5 kW system will require about 500 square feet of roofing space.

Of course, this number will vary depending on the specific characteristics of your roof, including the type, slope, orientation, and shading.

The Angle of the Roof

To calculate the number of solar panels you need for your roof, you need to take into account the angle of your roof. The amount of sunlight your solar panels get will also depend on the amount of sunlight, which in turn affects the amount of electricity that your panels can generate.

If your roof is at a steeper angle, it will receive more sunlight and you will need fewer panels. If your roof is at a shallower angle, it will receive less sunlight and you will need more solar panels for the roof.

The Amount of Electricity Usage

The amount of solar panels that you need for your roof depends on your electricity usage. For example, if you use 1,000 kWh of electricity per month, you would need approximately 27 solar panels.

However, if you use 3,000 kWh of electricity per month, you would need approximately 81 solar panels. Therefore, it is important to determine your electricity usage to determine how many solar panels you need for your roof.

Also, take note that the costs of installation should be factored in. This is to make sure that you are ready with your budget for the required solar panels for your roof. If you need 27 panels and you can only afford 20 for now, then that would do — however, you need to adjust your electricity usage.

Find Out How Many Solar Panels You’ll Need

If you’re planning on going solar, it is important to calculate how many solar panels you’ll need to power your home. You can use an online solar panel calculator and estimate your solar panel needs. Once you know how many solar panels you need, you can start shopping for solar panel kits and compare prices.
