Solar Panel Calculator: Find the Perfect Size for Your Home
Determine the ideal solar panel system for your house based on your desired electric bill offset.
How to Use the Solar Panel Calculator
Our solar power calculator helps you estimate the size and cost of a solar panel system for your home. Here's how to use it:
- Enter your average monthly electric bill.
- Specify the percentage of your bill you want to offset with solar energy.
- Input your local electricity rate (you can find this on your utility bill).
- Estimate the average daily sunlight hours in your area.
- Choose the wattage of the solar panels you're considering.
- Click "Calculate Solar System" to see your results.
This solar system cost calculator provides estimates for system size, number of panels, and potential costs. It's a great starting point for understanding your solar needs and potential solar savings.

Frequently Asked Questions
How many solar panels do you need to run a house?
The number of solar panels needed varies depending on your energy consumption, panel efficiency, and available sunlight. An average home might need between 20-30 panels, but our solar panel power calculator can help you estimate based on your specific situation.
What will a 100W solar panel run?
A 100W solar panel can power small appliances or devices, such as laptops, fans, or LED lights. For powering an entire house, you'd need a much larger system, which our solar price calculator can help you determine.
Is 10 kW enough to run a house?
A 10 kW solar system is substantial and can often meet the entire electricity needs of an average-sized home. However, the exact sufficiency depends on your energy consumption and location. Our solar panel cost calculator can help you determine if this size is right for your needs.
Can 4 solar panels power a house?
Four solar panels are typically not enough to power an entire house. They might offset a portion of your energy use or power specific appliances. Use our solar power calculator to determine how many panels you'd need for your whole home.
How many kW is 10 solar panels?
The total kilowatts from 10 solar panels depend on each panel's wattage. If each panel is 300W, 10 panels would produce 3 kW. For 400W panels, it would be 4 kW. Our solar system cost calculator allows you to input specific panel wattages for accurate estimates.
Can I have a 10KW solar system?
Yes, you can have a 10kW solar system if your roof space and local regulations allow it. This size is suitable for many homes with high energy consumption. Use our solar panel installation cost calculator to estimate the cost and feasibility of such a system.
Do solar panels work at night?
Solar panels don't generate electricity at night because they require sunlight. However, systems with battery storage can provide power after dark using energy stored during the day. Our solar production calculator factors in average daily sunlight hours to provide realistic estimates.
