Investing in solar panels is one of the smartest ways to reduce your energy bills and carbon footprint. However, like any other home system, solar PV installations require care and attention to stay efficient over time. Proper maintenance ensures your panels generate the maximum amount of electricity, prevents faults from developing, and helps you get the best return on your investment.
How to Keep Your Solar PV in Top Condition
Regular Cleaning for Maximum Efficiency
Dirt, dust, bird droppings, and pollution can build up on the surface of your solar panels, blocking sunlight and reducing output. Ideally, panels should be cleaned once or twice a year, depending on your environment. For homes near the coast in Brighton and Hove, salt and sea spray can also create a thin film that slightly dulls performance.
Use a soft sponge or brush with clean water, avoiding abrasive materials and detergents that could damage the glass. If your panels are on a pitched roof, always hire a professional cleaner for safety and to avoid invalidating your warranty.
Monitoring System Performance
Most modern solar PV systems include a monitoring app or inverter display showing real-time and historical performance. It’s a good idea to review this data monthly. If you notice a sudden drop in energy production or irregular readings, this may indicate a fault such as wiring issues, shading, or inverter problems. Early detection can save you both energy and money.
Inspecting for Damage and Shading
Inspect your panels visually from the ground at least twice a year. Look for cracks, corrosion, or loose fittings. Brighton’s coastal winds can occasionally loosen mounting brackets, so keeping an eye on fixings is important. Also check for shading caused by overgrown trees, chimneys, or new nearby structures. Even partial shade can significantly reduce your system’s efficiency, so trimming or repositioning obstructions can make a noticeable difference.
Maintaining the Inverter and Electrical Components
The inverter is the heart of your solar PV system, converting DC power from the panels into usable AC electricity. It’s often the component most prone to wear over time. Listen for unusual noises or check for warning lights. The average inverter lasts between 10–15 years, and having it checked regularly by a qualified electrician helps extend its lifespan and ensures safe operation.
Checking Connections and Cables
Although most solar systems are designed to be weatherproof, cables and connections can deteriorate or become loose over time. Routine professional maintenance will include checking electrical terminations, testing insulation resistance, and ensuring all wiring remains safe and efficient.
Scheduling Annual Professional Inspections
While homeowners can handle basic maintenance like visual checks and cleaning, a qualified solar electrician should inspect your system at least once every 12–24 months. They’ll test voltage output, examine the condition of the inverter, and verify that the system is compliant with current electrical safety standards. Preventative maintenance not only improves performance but also ensures your warranty and insurance remain valid.
