Regular maintenance is essential to protect your investment and the environment – so don’t skip those cleanings and inspections.

Cleaning Your Solar Panels Effectively

Keep your solar panels clean to maintain their efficiency and prolong their lifespan.

Manual cleaning becomes necessary in dry regions or areas with high levels of air pollution.

Power Washing in Dry Areas

Clean your solar panels using power washers twice per year in arid regions to remove accumulated dust and dirt without causing damage to the panel surface.

Hiring a professional for this service usually costs between $100 and $350.

Avoiding Soap and Hard Water During Cleaning

Avoid using soap or hard water when cleaning your solar panels as they can leave residue on the surface, reducing efficiency over time.

Opt for soft water mixed with a gentle glass cleaner designed specifically for use on photovoltaic surfaces.

  • Garden hose: Use a garden hose with concentrated glass cleaner to gently rinse away grime from the panel surfaces.
  • Pole brushes: Scrub gently using soft-bristle pole brushes designed specifically for use on solar panel surfaces.
  • Squeegees: Use a squeegee to remove excess water and prevent streaking.

Invest in specialized tools like soft-bristle pole brushes or squeegees for thorough cleaning without damaging delicate components within each unit.

By following these tips, you’ll ensure that your solar panels remain clean and efficient, maximizing the energy production of your system while minimizing maintenance costs over time.

DIY Methods for Cleaning Solar Panels

As a hands-on homeowner, you can keep your solar panels clean and efficient with these DIY methods.

Using a Garden Hose with Concentrated Glass Cleaner

Spray concentrated glass cleaner onto the panels and rinse with a garden hose on low pressure.

Scrubbing Gently with Soft-Bristle Pole Brushes or Squeegees

Gently scrub with soft-bristle pole brushes or squeegees to remove stubborn dirt spots or bird droppings.

  • Pole Brush: Attach a soft-bristle brush head onto an extendable pole designed for cleaning windows or gutters.
  • Squeegee: Use rubber-bladed squeegees specifically designed for window cleaning purposes.

Specialized solar panel cleaning kits are also available on the market containing biodegradable soap and soft brushes designed specifically for removing grime without causing damage.

Monitoring Inverter Functionality

Keep your solar panel system running smoothly by regularly checking your inverters, which convert DC electricity into AC electricity for use in your home.

Green Flashing Lights Indicate Good Performance

Green flashing lights mean your inverter is working efficiently, so check them periodically to ensure everything is running smoothly.

Red Lights Signal Potential Issues

Red lights on your inverter could indicate problems requiring immediate attention from qualified technicians or installers.

  • Maintain a regular inspection schedule: Schedule periodic inspections by experts to check your inverters.
  • Keep a log of inverter performance: Document any changes or issues you notice with your inverters.
  • Stay informed about product updates and recalls: Keep up-to-date on the latest news regarding your specific inverter model.

By monitoring your inverters and addressing potential issues promptly, you’ll ensure that clean power continues to flow seamlessly into your home for years to come.
