Looking after your solar panels

We've given you an operation and maintenance (O&M) manual that's filled with lots of useful information. This guide tells you what you can and can't do when it comes to your solar panel system. Please read this information carefully as it could invalidate your warranty and your system could stop working.

Do

Keep an eye on the solar panels. If the inverters are flashing green, that means they're working. If they're not flashing green, you'll need to arrange a repair.
To keep your solar panels working efficiently, make sure they are clear of leaves and dirt. Use a long-handled wiper to clean the panels while you're on the ground. This keeps you, and those around you, safe.
Call in the experts for any advanced maintenance, like changing an inverter.
In case of a fire, make sure anyone staying in your home is aware of where the "kill switch" is. This cuts off power to the panels so the fire services can do their job.

Don't

Let trees and shrubs cast shadows over your solar panels – trim any nearby plants.
Use abrasive soaps or cleaning cloths on the panels at any point. These could scratch the glass.
