The two sides of solar safety and how to get them both right
Solar system technology has established itself as both efficient and reliable, but safety must always remain the highest priority. As systems grow more advanced and connected, it is important that both physical risks, such as electrical faults, and cybersecurity vulnerabilities are pre-empted and managed to ensure safe and efficient operation.

Best practice for physical protection
Let’s start by looking at physical safety. With millions of systems installed worldwide, solar PV is proven to be a safe, reliable technology that does not inherently pose a risk to people or property. Commercial infrastructure fires can be caused by many things, including electrical malfunctions in heating systems, factory machinery or even lightning. While fires stemming from solar PV systems are rare, it is important to thoroughly evaluate the safety of any existing or planned installations, particularly when selecting or upgrading system components.

When a building fire is found to originate from a solar PV system, causes may include installation error or improper maintenance, particularly involving connector wear and tear. These errors may not cause a problem initially, but over time they can potentially lead to electrical faults, which, if not caught, can develop into something more serious. Fortunately, advances in solar system technology now enable effective detection and prevention of overheating at the connector level – a topic we’ll explore in more detail later in this article.
To support safer installations, many technology providers invest in ongoing
training. For example, SolarEdge has trained over two thousand professionals in the UK alone so far this year. However, even when installations are carried out flawlessly, external factors beyond anyone’s control, such as an animal chewing through a cable, can introduce faults. It is at this point that component selection becomes key.
Safety starts at the panel level Before we explore specific safety features, it is useful to first step back and review the individual components of solar PV systems – and how each can be secured.
