One of the biggest advantages of solar panels in North London is that they require very little maintenance. But to keep your system running at peak efficiency for 25+ years, there are a few simple checks and services you should consider.
.
🧽 Do Solar Panels Need Cleaning?
In most cases, rain does a good job of keeping your panels clean. However, in North London’s urban areas, dust, pollen, leaves, and bird droppings can reduce performance if left to build up.
- Light cleaning: Every 6–12 months
- Heavy shading / near trees: Every 3–6 months
💡 At Keenan Solar, we include free bird proofing with every install to help prevent mess and damage.
🛠 Professional Maintenance Checks
It’s worth booking a maintenance check every 2–3 years to ensure your system is working correctly. This includes:
- Inspecting panels and roof fixings
- Checking inverter performance
- Verifying cabling and electrical connections
- Reviewing your monitoring app data
🔋 Battery and Inverter Care
- Inverters typically last 10–15 years — keep an eye on efficiency in your app.
- Batteries can last 10–15 years if cycled properly. Regular software updates and smart tariff settings can extend their lifespan.
