What is a solar savings calculator?
A solar savings calculator is a free tool to estimate savings from installing solar panels. It uses information such as your system size, electricity rate, tax credits, and so on to calculate estimated long-term savings and return on investment.
The tool is perfect for understanding the financial side of installing solar before purchasing a system. This gives an idea of how much the solar panels will save each month and the break even time. So when the solar panels will pay themselves off.
The estimates shown are based on the values you enter and are intended for informational purposes only. Actual results would greatly depend on weather patterns, sun intensity, roof orientation, local utility pricing,maintenance costs, and more. As such, this tool is meant for a rough estimate for solar panel savings and roi.
How do I use this tool?
To use the calculator first start by entering in the information about your system. This includes the system cost, system size, annual degradation, electricity rate, annual rate increase, and tax incentives. Once you have entered in all of the information, the calculator will automatically update the project savings below.
After entering your information, the calculator will generate projected results such as net system cost after incentives, cost per watt, estimated payback period, monthly and yearly savings, annual solar production, estimated ROI, and long-term net profit.
