If you manage, own or have responsibility for a residential building, set aside some time to consider the wider safety implications of plug-in solar panel installations.
Establish a clear approval process
Residents should be encouraged to ask permission before installing plug-in solar systems. Unauthorised installations may affect building safety, insurance arrangements, lease conditions or management agreements.
Consider fire safety and means of escape
Solar panels and associated equipment should not block:
- Balconies which are shared - connecting apartments or common areas
- Corridors
- Walkways
- Windows
- Designated escape routes
Any installation that affects escape routes or access for firefighters should be carefully assessed.
Review external wall and remediation programmes
Where buildings are undergoing, or awaiting, remediation or cladding works, installation of plug-in solar systems should be carefully considered and may need to be postponed until work is complete.
Ensure electrical installations are suitable
Where outdoor sockets are provided for plug-in solar systems, they should be weatherproof, appropriately rated and installed by a competent person. The guidance recommends a minimum IP65-rated outdoor installation to reduce electrical faults and the risk of water getting in.
Encourage safe installation standards
Responsible persons should ensure residents understand the importance of following manufacturer instructions and using approved mounting systems. Where electrical work is required, for example fitting an outdoor socket, competent installers should be used.
Solar panels should not be installed on any combustible external wall system or timber balconies.
Consider implications for emergency planning
Responsible Persons should be aware that solar panels can continue producing electricity during daylight hours, even when switched off indoors. Building records, emergency plans and site information should be updated where appropriate to identify the presence of plug-in solar installations and support emergency response.
Notify the Distribution Network Operator (DNO)
Following installation, inform your local Distribution Network Operator (DNO) within 28 days, as plug-in solar systems generate electricity that can affect the operation and safety of the local electricity network. In London your DNO is UK Power Networks (UKPN).
