Substandard solar installations fuel infernos

The Zimbabwe Energy Regulatory Authority (ZERA) has identified substandard solar panel products and improper installations as the leading causes of fatal electrical accidents in the country, which have resulted in multiple deaths from infernos and electrocutions.

At least 27 fatalities have been recorded this year alone, with over 200 reported electrical accidents. This marks an alarming increase compared to the 45 deaths recorded from electrical incidents last year.

The statistics were disclosed during a ZERA engagement with stakeholders in Bulawayo last week. The event focused on gathering public feedback on the draft of the newly introduced Energy Solar Products and Installation Regulations Act (Espira), designed to bring order and safety to the rapidly growing solar sector.

ZERA senior engineer Man'arai Ndovorwi shared disturbing statistics, revealing that the country loses an average of three to four lives every month due to faulty solar installations and counterfeit solar products.

"We lose about three to four people every month due to bad installations, and we have heard numerous complaints from the market about fake products and poor-quality installations," Ndovorwi said. "Today, we are gathering public views on the Espira draft, specifically concerning solar products, installations, and the individuals responsible for setting up these solar systems."

Ndovorwi emphasized the need for all solar products imported into Zimbabwe to adhere to local standards, which are regulated by the Standards Association of Zimbabwe. He also highlighted the importance of proper training for those involved in solar system installations to ensure both quality and safety.

"For anyone involved in installing solar systems, they should have undergone proper training in designing and installing these systems safely. We need to ensure that safety mechanisms are in place to prevent accidents," Ndovorwi added.

A particular concern raised was the risky combination of solar-powered systems and connections to the national grid, which, if improperly installed, can result in electrocutions. Ndovorwi specifically pointed out that fowl runs—where many households extend their electricity connections for chicken rearing—have been noted as a significant contributor to electrical accidents. Improper installations in these areas are especially dangerous, as people often attempt to handle the setup themselves, neglecting safety precautions.

"People are setting up solar systems at their premises alongside ZESA installations, and if the installation isn't done properly, electrocutions can occur," Ndovorwi warned. "Fowl runs, where electricity is extended, have also been identified as major contributors to electrical accidents. Poor workmanship can lead to dangerous situations, with people being electrocuted inside these structures."

In an effort to curb the rising number of electrical accidents, Thubelihle Ndlovu, an electrical inspector for Bulawayo and the Matabeleland region, announced a new safety regulation that will require all households to install a mandatory circuit breaker.

"We are introducing a new regulation to reduce electrical accidents. A mandatory breaker will now be required for all households to ensure that in the event of any fault, even the smallest one, it will isolate the circuit and prevent a fatal incident," Ndlovu explained.

Current breakers in many homes are reportedly failing to detect faults, with the system not tripping until it's too late. However, the newly mandated breakers will be more sensitive and are expected to improve safety by preventing potentially deadly accidents.

ZERA's ongoing efforts to regulate the solar sector and improve electrical safety are aimed at reducing the frequency of such tragedies and ensuring that both solar installations and traditional electrical systems are safely maintained.
