Solar System Cost Calculator

Solar System Cost Calculator

Welcome to the Solar System Cost Calculator! This tool is designed to help you estimate the total cost and payback period of installing a solar power system at your home or business. By entering a few key details about your planned installation, you can get a clear picture of the financial investment required and the potential savings over time.


To use the calculator, you will need to provide the following information:

  1. Number of Solar Panels: Enter the solar panels you plan to install. This is a key factor in determining your solar power system’s overall capacity and cost.
  2. Cost per Panel ($): Input the cost of a single solar panel. This cost can vary based on your chosen panels’ type, brand, and efficiency.
  3. Installation Cost ($): Provide the total solar panel installation cost. This includes labor, permits, and any additional hardware needed.
  4. Expected Savings per Year ($): Estimate the money you expect to save on your electricity bills each year from installing the solar power system.


After entering the required inputs, the calculator will provide you with the following results:

  1. Total Cost: This is the sum of the cost of the solar panels and the installation cost. It represents the total financial investment needed to install your solar power system.
  2. Payback Period: This indicates how many years it will take for the savings on your electricity bills to cover the total cost of the solar power system. A shorter payback period means a quicker return on your investment.

How It Works

The Solar System Cost Calculator works by multiplying the number of solar panels by the cost per panel to get the total cost of the panels. It then adds the installation cost to this amount to get the system’s total cost. The payback period is calculated by dividing the total cost by the expected annual savings.

For example, if you plan to install 10 solar panels for $300 per panel, with an installation cost of $2,000, and you expect to save $1,000 per year on your electricity bills, the calculator will determine the following:

  • Total Cost: (10 panels * $300) + $2,000 = $5,000
  • Payback Period: $5,000 / $1,000 per year = 5 years


The Solar System Cost Calculator is a valuable tool for anyone considering installing a solar power system. It provides a clear estimate of the total cost and payback period, helping you make informed decisions about your investment in renewable energy. Use this calculator to plan your solar installation and take a step towards sustainable and cost-effective energy solutions.
