Solar Panel Fires Surge in Nigeria as FG Enforces New Safety Rules

The Federal Government, through the Nigerian Electricity Management Services Agency (NEMSA), has raised serious concerns over the increasing number of fire outbreaks linked to poorly installed rooftop solar systems across the country, warning that the trend poses a growing threat to lives, property, and Nigeria’s clean energy transition.

In recent years, millions of Nigerians have turned to solar energy in Nigeria as a reliable alternative to the erratic national grid. With persistent blackouts, rising fuel costs, and unstable electricity supply, households and businesses are rapidly adopting rooftop solar photovoltaic (PV) systems. However, authorities say the surge in installations—many carried out by unqualified technicians—has led to a spike in solar panel fire incidents and electrical hazards.

In a strongly worded public notice signed by the Chief Electrical Inspector of the Federation, NEMSA said it had observed “with serious safety concern” the growing number of fire outbreaks allegedly linked to improperly installed rooftop solar PV systems nationwide. The agency stressed that while the adoption of renewable energy in Nigeria remains critical to national development and climate goals, safety standards must not be compromised.

According to NEMSA, investigations into recent incidents revealed that most of the fires were caused by poor workmanship, use of substandard or counterfeit materials, absence of essential protective devices, and widespread non-compliance with technical regulations. These lapses, the agency warned, significantly increase the risk of overheating, electrical faults, and eventual fire outbreaks in residential and commercial buildings.

Backed by provisions of the Electricity Act 2023, NEMSA has now issued comprehensive guidelines aimed at regulating solar installation safety in Nigeria. The agency made it mandatory for all solar PV installations to be handled strictly by certified professionals. It warned that the growing number of informal and untrained installers in the market is a major contributor to unsafe practices and system failures.

Under the new directive, only NEMSA-certified electrical contractors are permitted to install rooftop solar systems, and such contractors must present valid competency certificates during installation. The agency emphasised that proper planning must precede installation, including detailed load assessments to ensure systems are appropriately sized and capable of handling energy demand safely. It also stressed that rooftops must be structurally sound to support solar panels, noting that weak or poorly constructed roofs could lead to structural damage or even collapse.

NEMSA further highlighted technical defects commonly associated with faulty solar systems, including cracked panels, bent frames, loose junction boxes, and internal hot spots. These issues, it said, can trigger electrical arcing and overheating, which are leading causes of solar-related fire outbreaks. To prevent such risks, installers are required to maintain a minimum clearance between solar panels and roofing materials to allow adequate ventilation and cooling, especially during high temperatures.

On electrical protection, the agency mandated the installation of critical safety components such as DC and AC isolators for emergency shutdown, circuit breakers and fuses to prevent overload, and surge protection devices to guard against lightning strikes. Proper earthing of the entire system, with resistance not exceeding recommended safety limits, was also identified as essential in reducing the risk of electrical faults and fires.

Special attention was given to battery storage systems, particularly lithium-ion batteries, which are increasingly used in modern solar setups. NEMSA warned that improper battery installation has been a major factor in fire incidents globally. It directed that batteries must be installed in well-ventilated and secure locations away from living spaces and heat sources. For lithium batteries, the use of a battery management system (BMS) and adequate temperature control measures, such as cooling or air-conditioning systems, was made compulsory.

The agency also addressed system design issues, noting that in cases where solar capacity cannot power an entire building, installers must implement proper load separation at the distribution board. Additionally, all solar cables must be neatly arranged in conduits or trunking, while communication and power cables must be routed separately to avoid interference, overheating, and increased fire risks.

Beyond installation, NEMSA emphasised the importance of routine maintenance in ensuring long-term safety and performance. It advised system owners to regularly clean solar panels to prevent dust accumulation, inspect cables and connectors for wear or damage, and promptly replace faulty components. Neglecting maintenance, the agency warned, can gradually compromise system integrity and increase the likelihood of fire outbreaks.

The government’s warning comes amid growing concerns that Nigeria’s fast-expanding solar market lacks sufficient regulation and oversight. Energy experts believe that without strict enforcement of standards and increased public awareness, the rise in solar panel fire incidents in Nigeria could undermine confidence in renewable energy adoption.

NEMSA concluded by urging installers and members of the public to strictly comply with the new guidelines, stressing that adherence is crucial for safety, system efficiency, and regulatory compliance as Nigeria continues its transition toward cleaner energy sources.
