The Nigerian Electricity Management Services Agency has raised serious concerns over the growing number of fire incidents linked to improperly installed rooftop solar systems across Nigeria, warning that poor installation practices could endanger lives and property.
In a public notice issued from its headquarters in Abuja, the agency said investigations revealed that many of the incidents stem from substandard materials, poor workmanship, and failure to comply with technical regulations guiding solar photovoltaic installations.
NEMSA noted that while the adoption of renewable energy remains critical to Nigeria’s energy transition, safety must not be compromised. The agency stressed that many installations currently in use fall short of required standards, increasing the risk of electrical faults, overheating, and fire outbreaks.
Citing provisions of the Electricity Act 2023, the agency directed members of the public and industry operators to engage only certified professionals for solar installations. It added that all completed systems must undergo proper inspection, testing, and certification before being put into use.
The agency further warned that rooftop solar systems must be installed on structurally sound surfaces capable of supporting the equipment, noting that weak roofing or poor mounting could lead to damage and safety hazards. It also emphasised the need for proper load assessment to ensure systems are correctly sized for each building.

NEMSA highlighted that mismatched or damaged solar panels, faulty connectors, and poorly rated cables remain major causes of system failure. It warned that incorrect wiring or undersized cables could lead to overheating and significantly increase fire risk.
The agency also stressed the importance of installing protective devices, including circuit breakers, surge protection systems, and proper grounding to guard against electrical surges and lightning strikes. It added that battery storage systems must be kept in well-ventilated and secure locations, away from heat sources, with appropriate cooling mechanisms in place.
In its advisory, NEMSA pointed out that safety measures must extend beyond installation to regular maintenance. It urged system owners to carry out routine checks, clean solar panels, and promptly replace any faulty components to maintain efficiency and reduce hazards.
The agency also cautioned against connecting solar systems to existing power networks without proper certification, warning that such practices could compromise both system performance and public safety.
Reaffirming its regulatory mandate, NEMSA called on installers, developers, and electricity consumers to adhere strictly to safety standards, stating that compliance is essential for protecting lives, ensuring system reliability, and supporting Nigeria’s clean energy goals.
The warning comes amid a surge in demand for alternative power solutions as households and businesses increasingly turn to solar energy to address electricity supply challenges.
