The London Fire Brigade has issued safety advice for Londoners thinking about installing plug-in solar panels.
Unlike traditional solar panels, which are typically wired into the roof of a home, these panels can be placed on a terrace, shed or balcony and are plugged into a wall socket.
The brigade advises anyone considering buying plug-in solar equipment to get it from a trusted manufacturer or retailer. Buying from a reputable seller reduces the risk of picking up a poor-quality or counterfeit product, which could overheat or fail.
Assistant commissioner Pam Oparaocha said: "As with any new to the market electrical appliances, there may be associated fire risks, and as Londoners start installing the new plug-in solar panels, we urge them to look at our safety tips to keep themselves and others safe.
"Ensure your appliance meets the UK safety standards and is installed correctly - being careful not to block any fire escape routes. During an emergency, firefighters need unrestricted access to your property, so make sure you aren't blocking emergency exits, doors, balconies or windows.
"If you notice your device overheating or any other signs of a fault, stop using it immediately and report the issue. Should your appliance catch fire call 999 and inform the operator that solar panels are installed at the property. Doing so will help our crews respond as quickly and safely as possible."
