Do Solar Panels Need Maintenance?
Solar panels are known for being low-maintenance, but does that mean they don’t need any care at all? If you’re wondering, “Do solar panels need maintenance?” the answer is yes, but very little. Unlike other energy systems, solar panels have no moving parts, meaning there’s minimal wear and tear. However, some routine maintenance can help maximise efficiency and extend their lifespan.
In this guide, we’ll explain what solar panel maintenance involves and how to keep your system running smoothly.
How Often Do Solar Panels Need Maintenance?
In most cases, solar panels only need occasional cleaning and inspections. Dirt, dust, and debris can accumulate over time, reducing efficiency. If your panels are in a location with heavy pollution, bird droppings, or lots of trees, you may need more frequent cleaning.
A general rule of thumb is to inspect your panels every 12 months and clean them as needed.
What Maintenance Do Solar Panels Require?
1. Cleaning the Panels
Dirt and debris can block sunlight, reducing energy output. Cleaning your panels can improve efficiency by up to 5-10%.
2. Checking for Damage
Although solar panels are built to withstand harsh weather, they can still develop cracks or other minor issues. Regularly inspect for:
- Cracks or chips in the glass (which may affect performance).
- Loose or damaged wiring (which could cause system inefficiencies).
- Bird nests or pest infestations under the panels.
If you notice damage, contact us for repairs.
3. Monitoring Energy Production
Most modern solar systems come with monitoring software that tracks energy output. If you notice a sudden drop in efficiency, it may indicate a problem such as:
- Shading from new tree growth or nearby structures.
- A faulty inverter (which converts solar energy into usable electricity).
- Dirt build up affecting sunlight absorption.
Regularly checking your monitoring system ensures your panels are working at peak efficiency.
Do Solar Batteries Need Maintenance?
If your solar system includes battery storage, some additional maintenance is required. Here’s what to check:
- Keep batteries clean and dry to prevent corrosion.
- Check battery connections for loose or worn-out wires.
- Monitor battery performance to ensure they’re storing and discharging energy correctly.
Most modern lithium-ion batteries require minimal maintenance compared to older lead-acid models.
How Long Do Solar Panels Last?
Solar panels typically last 25-30 years with proper care. While their efficiency gradually decreases over time, a well-maintained system can still produce energy for decades.
Manufacturers usually offer performance warranties of 20-25 years, ensuring panels continue generating at least 80-90% of their original capacity over time.
Do You Need Professional Solar Maintenance?
For most solar panel owners, DIY maintenance like cleaning and visual inspections is enough. However, professional servicing may be needed if:
- Your panels are hard to access safely.
- You notice significant drops in energy production.
- Electrical components, like the inverter, show signs of failure.
A professional solar technician can conduct a thorough system check, including electrical testing and performance optimisation.
