The Federal Government, through the Nigerian Electricity Management Services Agency (NEMSA), has warned Nigerians about rising fire incidents linked to poorly installed rooftop solar photovoltaic systems across the country.
NEMSA said the growing adoption of solar energy, driven by persistent power shortages, has unfortunately led to safety risks due to unqualified installers, substandard materials, and non-compliance with technical standards.
According to the agency, many of the reported fire outbreaks are caused by poor workmanship, lack of protective devices, and failure to follow approved electrical installation guidelines.
In a public notice signed by the Chief Electrical Inspector of the Federation, NEMSA stressed that while renewable energy adoption is encouraged, safety must not be compromised.
The agency cited provisions of the Electricity Act 2023, stating that only NEMSA-certified electrical contractors are legally permitted to install rooftop solar systems in Nigeria.
It directed that installers must conduct proper load assessments, ensure roofs are structurally sound, and use approved mounting structures to prevent overheating, fire hazards, or system failure.
NEMSA also warned against using damaged or defective solar panels, including those with cracks, bent frames, or faulty junction boxes, noting that such defects increase the risk of electrical faults and fire outbreaks.
For electrical safety, the agency mandated the installation of protective devices such as circuit breakers, fuses, surge protectors, and proper earthing systems, as well as maintaining adequate ventilation between panels and roofing materials.
It further advised that batteries, especially lithium types, must be installed in well-ventilated, secure locations with proper cooling systems and battery management controls.
The agency also emphasized proper cable routing, warning that power and communication cables should not be run together to avoid interference and fire risks, while all installations must be regularly inspected and maintained.
NEMSA urged Nigerians to strictly comply with these guidelines and engage only certified professionals, warning that non-compliance could lead to system failure, property damage, or loss of life.
