As more homeowners are turning to renewable energy alternatives, solar panels have become a popular choice for generating clean electricity. However, like any other home improvement project, solar panels require regular maintenance to ensure they operate effectively and last for many years to come. In this guide, we will explore the importance of solar panel maintenance, including how to clean your solar panels, as well as common issues and solutions to help keep your solar panels in top shape.
The Importance of Solar Panel Maintenance
Although solar panels are designed to be durable and withstand the elements, they still require regular maintenance for several reasons.
- Maximising Energy Production – Dust, dirt, or debris can accumulate on solar panels, blocking sunlight and therefore their energy efficiency. Regular cleaning helps to maintain higher levels of energy production and greater savings on electricity costs.
- Extends Lifespan – Proper maintenance can extend the lifespan of your solar panels by preventing damage and wear and tear, in turn maximising your return on investment.
- Prevents Issues & Damage – Regular inspections can help identify potential problems before they occur, thereby preventing damage. By not conducting regular checks of your solar panels, issues such as debris buildup, hotspots, shading, or damaged panels can occur, which can hinder overall performance.
- Ensures Safety – Keeping your solar panels in good condition reduces the risk of electrical issues or fire hazards.
Inspect Your Solar Panel
When maintaining your solar panels, it is essential to conduct regular inspections to prevent potential issues. Here are a few key things to look for:
- Visual Inspection – Check for cracks, chips, or discolouration on the panels. Also, inspect the surrounding areas for any signs of shading from nearby trees or buildings.
- Check Your Inverter – Ensure the inverter is functioning correctly. Most inverters have a display that shows performance data. If you notice a drop in output, it may indicate a problem.
- Wiring – Inspect the wiring for any signs of wear or damage. Loose connections can lead to inefficiencies or safety hazards occurring.
- Professional Inspections – For an added level of security and peace of mind, consider scheduling a professional to inspect your solar panels every few years. They can identify issues that may not be noticeable without their knowledge and expertise.
How To Clean Solar Panels
Cleaning your solar panels is one of the most straightforward yet vital maintenance steps. Here are some tips to get you started:
- Safety – Always turn off your solar panels before cleaning. If your solar panels are on a roof, consider hiring a professional for your safety.
- Tools – Using the right tools for the job, such as a soft brush or microfibre cloth, a hose, and a gentle spray, will effectively clean your solar panels without causing them any damage. Avoid using harsh chemicals or abrasive materials, as they can damage your solar panels.
- Technique – A helpful tip when cleaning your solar panels is to start from the top and work your way down, preventing dirty water from running onto clean areas. For areas with stubborn dirt, use a bucket of warm, soapy water.
When to Clean
Aim to clean your solar panels at least twice a year. However, if you live in an area prone to dust or near trees, more regular cleaning may be necessary.
Clean your solar panels on a cool, overcast day to prevent streaking from the heat of direct sunlight.
Common Issues & Solutions: Solar Panels
Solar panels can face some common issues that homeowners nationwide encounter, affecting their performance and energy efficiency. If you are facing an issue with your solar panels, you might not be alone. Read on to find out if your solar panels are facing a common problem, and how you can fix this:
- Dirt and Debris Buildup – The key solution to this is to conduct regular checks and cleaning (refer to the earlier section ‘How to clean solar panels’).
- Physical Damage – Carry out regular inspections for cracks, chips, or other damage that could be hindering the performance of your solar panels. For damaged panels, enquire about professional repair or replacement.
- Shading Issues – Trim back any trees or vegetation that may be casting shadows on your panels. This can significantly improve their efficiency.
- Roof Leaks – If you notice water stains or leaks in your home, it could be a consequence of the improper installation of the solar panel mounting system. Consult a professional to inspect the installation to ensure that it’s watertight.
- Inverter Failure – If your inverter is malfunctioning, it may be a sign that it needs replacing. Always consult a professional to carry out this task.
