Our solar calculator helps you determine how many solar panels you need to power your home based on your energy consumption. The calculator estimates system size, annual energy production, cost savings, and payback period to help you evaluate whether solar makes financial sense for your situation.
Solar system sizing depends on your energy usage, available sunlight (peak sun hours), and what percentage of your usage you want to offset. The calculator uses industry-standard assumptions for panel output but actual results vary based on panel efficiency, orientation, shading, and local climate.
This tool is perfect for homeowners considering solar installation, anyone asking "how many solar panels do I need for my house?", and those evaluating the financial benefits of going solar. For accurate quotes, consult with local solar installers who can assess your specific roof and energy situation.
