The Federal Government has warned Nigerians about a rising number of fire incidents linked to improperly installed rooftop solar photovoltaic systems across the country, urging stricter safety compliance as more households and businesses switch to solar power.
The warning was issued by the Nigerian Electricity Management Services Agency (NEMSA), which said it had observed a troubling increase in fire outbreaks traced to faulty solar installations, substandard materials, and unqualified installers.
According to the agency, while the adoption of solar energy is a positive step in Nigeria’s energy transition, safety standards are being widely ignored in many installations.
NEMSA explained that several of the incidents recorded were caused by poor workmanship, lack of protective devices, and failure to follow basic technical guidelines.
In its public notice, the agency stressed that only certified electrical contractors should be engaged for solar installations, warning that unqualified technicians pose serious risks to lives and property.
It also outlined key safety requirements, including proper load assessment before installation, use of structurally sound roofs, and correct mounting of solar panels to avoid collapse or overheating.
The agency further warned against using damaged or defective solar panels, noting that cracks, loose wiring, and internal faults can lead to electrical failure or fire outbreaks.
To reduce risks, NEMSA directed that adequate spacing must be maintained between roofing materials and solar panels to allow proper ventilation, especially during high temperatures.
It also mandated the installation of safety devices such as circuit breakers, fuses, surge protection systems, and proper earthing to prevent electrical surges and lightning-related damage.
For battery systems, the agency advised that they must be installed in well-ventilated areas away from heat sources, while lithium batteries must be fitted with proper management systems to regulate performance and temperature.
NEMSA also stressed the importance of proper cable management, warning against running power and communication cables in the same conduit due to the risk of interference and fire hazards.
The agency added that solar systems must be regularly inspected and maintained, including cleaning of panels, checking of wiring, and timely replacement of faulty components.
It urged Nigerians to take the guidelines seriously, stating that strict adherence is essential not only for system efficiency but also for safety and regulatory compliance.
