Investing in a solar system for your home is a decision that pays off in multiple ways—increased property value, reduced energy bills, and a smaller carbon footprint. But to reap these benefits for the long term, proper maintenance is crucial. Whether your solar panels are ground-mounted or roof-mounted, understanding how to keep them in optimal condition is key.

Frequency of Cleaning: Less is More

Contrary to popular belief, solar panels don’t require frequent cleaning. A semi-annual cleaning schedule is generally sufficient. Some homeowners opt for an annual inspection by a solar professional to ensure the system is functioning at its peak. This is often a service provided by the installation company, like San Diego County Roofing & Solar, at a minimal cost.

The Right Way to Clean Solar Panels

The primary goal when cleaning solar panels is to remove accumulated dirt, leaves, and other debris. If your panels are tilted, natural elements like rain and wind can aid in keeping them clean. However, in drier climates, manual cleaning may be necessary.

Professional Cleaning: Safety First

For roof-mounted panels, it’s advisable to hire a professional cleaning service. While the cleaning tools are straightforward, the required safety equipment may not be readily available to all homeowners. A professional service will either charge per panel or offer a flat rate for the entire system.

Snow Guards: An Overlooked Necessity

If you reside in an area prone to heavy snowfall, consider installing snow guards. Solar panels are nearly frictionless, making them prone to snow slides that can be hazardous. Snow guards effectively mitigate this risk.

Monitoring System: Your Solar Health Tracker

Modern solar systems often come with monitoring devices or apps that allow you to track energy production. Regularly checking these metrics can alert you to any significant dips in energy output, signaling that it might be time for a cleaning or inspection.

Warranty: Your Safety Net

Quality solar panels usually come with a production warranty, ensuring that the panels’ energy output remains at or above 80% for a specified period, often 25 years. This warranty is your assurance against any significant decrease in panel efficiency or malfunctions.


Maintaining your solar system is not as daunting as it may seem. Simple steps like semi-annual cleaning, occasional professional inspections, and regular monitoring can go a long way in ensuring that your investment continues to pay off.
