Do solar panels cause fires?
Solar panel fires are very rare, and when they do occur they are almost always caused by poor installation or faulty components rather than the panels themselves. Using an MCS-certified installer, quality parts and correct isolators and protection keeps the risk very low, comparable to any other well-installed electrical system.
Why the risk is low
- MCS installers follow strict wiring and protection standards.
- Quality connectors and isolators reduce the main failure points.
- DC isolators and proper earthing are part of a compliant install.
- Regular monitoring helps spot a fault early.
Keeping it safe
Choose an MCS installer, insist on quality components with good warranties, and have the system inspected if you notice anything unusual such as a sudden output drop or a burning smell. Batteries should use safe modern chemistries (LFP is the home standard) and be installed by a competent fitter.
Frequently asked questions
