A typical home in the United States would require 19-23 solar panels. It is based on the average electricity consumption of 877 kWh. It will cost between $13,000 and $16,000 to install 19-23 solar panels. On the surface, this appears to be a significant investment, but it also has numerous cost-saving benefits over time. There are numerous factors to consider when determining how many solar panels are required to power your home. After accounting for all of this, the math becomes quite simple. We will simplify this assessment by explaining its various components.
Factors to consider when determining how many solar panels are best for your home
Energy consumption
If you want to know how many solar panels required, you should know how much electricity you use annually, monthly, and daily on average. The average energy consumption varies from house to house. It is determined by factors such as the total number of people in the house and the total number of electrical appliances.
You can check your previous year’s bills to see how much electricity you used during each season. After you have the digits, you will know how much solar power you need to meet your needs. An American home uses approximately 10649 kWh of energy per year on average. If you do the math, you’ll see that it comes down to 29kWh per day.
Sunlight
If you live in a city that receives less sunlight, you will require more solar panels than if you live in a city that receives more sunlight. Only then will it assist you in paying your electricity bills. In general, southwestern towns and states receive the most sunlight, while northeastern areas receive the least.
Panels for solar energy
Individual solar panels have the potential to produce a significant amount of energy. It is also affected by factors such as sunlight and the amount of shade provided by the roof. This is the power rating, which is measured in watts.
The calculation
Now that we’ve considered all of the variables, we can calculate the total number of solar panels you’ll require for your home. Here’s an illustration.
Your home receives four hours of sunlight per day, and you recently purchased 325W solar panels. In this case, each solar panel will produce approximately 1.3kWh per day. If your daily energy consumption is 29kWh, you will need approximately 23 solar panels with a 325W output to power your home.
Important advantages
So, those are the fundamentals of calculating the optimal number of solar panels for your home. These items may appear to be expensive, but you can always save money by investing in them.
For example, if you can’t afford to buy a solar panel, you can rent one. In addition, the federal government offers a tax break for new solar installations. Aside from that, many governments offer incentive programs. However, one major issue is that the majority of solar panels are manufactured in China.Β
