3. Routine Solar Energy System Maintenance Tasks
To keep your solar system in top condition, certain routine tasks should be performed regularly. Some of these can be handled by the system owner, while others require professional service.
a) Cleaning Solar Panels
Solar panels can accumulate dirt, dust, pollen, bird droppings, leaves, and other debris over time, which reduces their ability to capture sunlight effectively. Regular cleaning is crucial, particularly in areas with high pollution or dust levels.
How to clean solar panels:
- Use a soft brush, sponge, or cloth with water to gently wipe down the surface of the panels.
- Avoid using harsh chemicals or abrasive materials that could scratch the glass.
- If cleaning the panels yourself, be cautious when working on the roof or hire a professional for safety reasons.
For optimal results, it’s advisable to clean your panels once or twice a year, depending on your location and climate.
b) Inspecting the Inverter and Wiring
The inverter is one of the most critical components of your solar energy system, converting DC power from the panels into usable AC power. Inverters should be checked for signs of wear, corrosion, or damage.
What to inspect:
- Ensure the inverter’s display or monitoring system shows normal readings.
- Check for any loose connections, wiring issues, or corrosion around the electrical components.
- If you notice unusual sounds or performance drops, contact a professional for a detailed inspection.
c) Checking for Shading Issues
Solar panels need direct sunlight to perform at their best. Over time, trees or new constructions can cast shadows on your panels, reducing their efficiency. Periodically check for any new shading and trim back trees or branches that may obstruct sunlight.
d) Monitoring System Performance
Most solar energy systems come with a monitoring platform that tracks energy production and usage. Regularly reviewing this data helps you identify any sudden drops in performance, which could indicate a problem with your system.
Set up alerts or notifications from your monitoring system to receive immediate updates if something goes wrong.
e) Checking Mounts and Seals
Solar panels are mounted on your roof or the ground using brackets and mounts. Over time, these fixtures can loosen or become damaged due to weather, wear, or animal interference.
Inspect the mounting system for:
- Loose bolts or brackets.
- Roof seals that may have worn down or cracked, potentially causing leaks.
- Rust or other signs of degradation in the mounting hardware.
4. When to Call a Professional for Solar System Service
While many maintenance tasks can be performed by the homeowner, some issues require the expertise of a professional solar technician. Here are scenarios where you should consider professional service:
- Decreased Energy Production: If your system’s output suddenly drops without an obvious reason (such as shading or weather changes), a professional inspection is necessary to diagnose and fix the issue.
- Inverter Malfunctions: Inverter issues can be complex and dangerous. If the inverter shows error codes or stops functioning, contact a certified technician.
- Electrical Problems: If you notice exposed wires, burning smells, or sparks around the electrical components, turn off your system and call an expert immediately.
- Physical Damage: After storms, hail, or other weather events, inspect your panels for cracks or damage. If any panels appear broken or bent, a professional should assess the damage and provide repairs.
5. Preventative Solar Energy System Maintenance
One of the best ways to avoid major repairs and extend the life of your system is by scheduling regular preventative maintenance. Many solar companies offer maintenance packages that include annual or bi-annual inspections, cleaning, and system checks.
Professional preventative maintenance typically includes:
