A Simple Guide to Looking After Your Solar Panels

Ensure Your Solar Panels Are Running at Their Best All Year Round

Solar panels are a fantastic way to save money on energy bills and do your bit for the environment. But like any other home investment, they require a little bit of care and attention to ensure they keep performing at their best.

1. Keep Your Solar Panels Clean

Over time, dirt, dust, and debris can build up on your solar panels, preventing them from capturing as much sunlight and reducing their efficiency. Keeping them clean is a simple but essential task.

• Tip: Use a soft cloth or sponge with lukewarm water to gently clean the panels. Avoid harsh chemicals or abrasive materials that could damage the surface. For stubborn dirt, a mix of water and mild soap should do the trick. If you’re unsure about cleaning them yourself, it’s always worth calling in a professional.

2. Check for Debris or Obstructions

Sometimes, leaves, branches, or even bird droppings can block sunlight from reaching your solar panels. It’s a good idea to check for any obstructions, particularly after bad weather or storms.

• Tip: Inspect your panels regularly, especially in autumn when leaves tend to fall. If you spot any debris, gently remove it, making sure not to scratch or damage the surface.

3. Keep an Eye on Performance

Monitoring your solar panels’ performance is one of the easiest ways to spot issues early. Many systems come with monitoring apps or tools that let you track how much energy is being produced.

• Tip: Check the performance of your system from time to time. If you notice a drop in energy generation, it could indicate dirt build-up, shading, or a potential technical fault. Addressing any issues quickly helps avoid bigger problems down the line.

4. Look for Signs of Damage

While solar panels are built to last, they can still suffer from wear and tear, particularly after severe weather. Cracks, chips, or issues with wiring can all affect their efficiency.

• Tip: Inspect your panels at least once a year for visible signs of damage. If you find any cracks or damage, get in touch with a professional to assess the situation and carry out any necessary repairs.

5. Check the Tilt and Position

For solar panels to perform at their best, they need to be positioned at the right angle to catch as much sunlight as possible. Over time, settling or shifting of the roof might affect the angle of the panels.

• Tip: If you notice a drop in performance, it may be worth checking whether the tilt or orientation of your panels is still ideal. A professional can help adjust the position if needed.

6. Maintain Surrounding Vegetation

Plants, trees, and shrubs growing near your solar panels can cause shading, which reduces the amount of sunlight they receive. Overgrown plants can also drop debris onto the panels.

• Tip: Trim any plants or trees around your solar panels to prevent shading. Keeping the area clear of vegetation will ensure your system works as efficiently as possible.

7. Book a Professional Inspection

While regular checks can be done by yourself, it’s always a good idea to have a professional inspect your solar panels every few years. A qualified technician will be able to spot issues that might not be obvious, such as wiring problems or faults with the inverter.

• Tip: Schedule a professional inspection every 1-2 years. A thorough inspection will ensure that everything is working as it should, and any potential issues can be resolved early.

8. Look After the Inverter

The inverter plays a vital role in your solar panel system, converting the electricity your panels generate into usable power for your home. If the inverter isn’t working properly, your system won’t produce energy as efficiently.

• Tip: Check the indicator lights on your inverter regularly. If you see a red or flashing light, it could indicate a fault. Contact a professional if you think there might be an issue with the inverter.

9. Protect from Extreme Weather

Although solar panels are built to withstand various weather conditions, extreme events like heavy snow, hail, or strong winds can sometimes cause damage.

• Tip: In areas with severe weather, it’s a good idea to remove snow from the panels when possible. During strong winds, check that the panels are securely fastened to avoid damage.

10. Keep Track of Warranties and Documentation

Solar panels usually come with warranties, often lasting 20-25 years. It’s important to keep track of the warranty and maintenance records in case any issues arise during this time.

Tip: Review your system’s warranty and make sure you keep all documentation related to maintenance or repairs. If anything goes wrong, you’ll want to have the necessary information to make a warranty claim.
