Solar Panel Cleaning Cost Calculator
Estimate the likely cost of cleaning your solar panels and compare it with the possible value of recovering lost production.
Estimate solar panel cleaning costs and potential savings
Use your system details and electricity rate to explore a planning estimate. Actual cleaning needs, production impact, pricing, and safe access requirements vary by property, equipment, weather, and local contractor.
This calculator estimates how much energy and money you may be losing each month due to dust and dirt reducing your solar panel efficiency. Calculations are based on your system size or panel area, your local electricity rate, and your estimated energy loss.
Electricity rates used in this tool are based on data from SDG&Eās Joint Rate Comparison as of February 2025.

šø Solar Panel Dirt Loss Calculator
Estimate how much dirty panels could be costing you each month or year.
ā ļø This tool provides an estimate based on average production assumptions. Actual output may vary depending on panel type, shading, angle, location, and soiling pattern.
Use your estimate to compare options
- Confirm whether your panel manufacturer and installer provide cleaning or maintenance guidance.
- Compare written service scopes, safety practices, insurance, and pricing from qualified local providers.
- Review your system's actual production before assuming that cleaning will produce a specific savings result.
