The rapid rise of rooftop solar installations across the Philippines is prompting stronger calls from engineers and power industry leaders for stricter regulation and enforcement of safety standards, amid growing concerns over improperly installed systems that could threaten public safety and grid stability.
The Institute of Integrated Electrical Engineers of the Philippines, Inc. (IIEE) said the country’s transition toward renewable energy must be accompanied by responsible implementation, proper engineering practices, and strict compliance with existing electrical and safety regulations.
While expressing full support for the expansion of rooftop solar photovoltaic (PV) systems, the organization warned against the increasing presence of unregistered and non-compliant installations that bypass professional supervision, permitting processes, inspections, and coordination with distribution utilities.
“As rooftop solar adoption accelerates nationwide, renewable energy development must always be pursued alongside strict adherence to electrical safety standards, sound engineering practices, and existing laws intended to protect life, property, public safety, and grid reliability,” the IIEE said in a statement.
The group stressed that rooftop solar systems should only be designed, installed, tested, commissioned, and maintained by qualified and licensed electrical practitioners in accordance with Republic Act No. 7920, the Philippine Electrical Code, and applicable rules issued by the Department of Energy and the Energy Regulatory Commission.
IIEE cautioned that improperly installed solar systems may expose consumers and communities to risks such as electrical fires, electrocution, unsafe back-feeding conditions, equipment malfunction, and power quality disturbances that could affect the broader electricity network.
The engineering organization also underscored the importance of using certified and standards-compliant equipment, including solar panels, inverters, batteries, protective devices, and wiring systems.
“The use of uncertified or substandard equipment undermines consumer protection, public safety, and the integrity of the electrical industry,” the institute said.
The call for stronger regulation comes as more households and businesses turn to solar technology in an effort to reduce electricity costs and improve energy efficiency.
Manila Electric Company (Meralco), for its part, said it has also been actively adopting solar technologies within its own operations as part of its sustainability agenda.
“Meralco has installed and continues to install solar panels in our own facilities for the same reason many households and businesses are now exploring solar technology, as it helps us use electricity more efficiently and responsibly,” said Ronnie L. Aperocho, Executive Vice President and Chief Operating Officer of Meralco.
Since 2020, the power distributor has implemented its Resource Conservation and Efficiency Program, which includes the installation of solar panels in its headquarters, business centers, and sector offices to help reduce operational energy use.
Aperocho said Meralco believes companies promoting energy-efficient technologies should also lead by example through their own sustainability initiatives.
“We believe that if a technology can help save resources and improve efficiency, we should also practice it ourselves,” he said.
Meralco also cited the role of its solar subsidiary, MSpectrum, in helping households and enterprises shift to cleaner and more sustainable energy solutions.
The company said it will continue advocating for the responsible adoption of solar energy and other environmentally friendly technologies while supporting long-term sustainability goals.
The statements from both IIEE and Meralco reflect growing momentum within the energy sector to strengthen oversight on renewable energy technologies as rooftop solar adoption expands nationwide.
Industry stakeholders noted that while solar power remains a critical component of the country’s clean energy transition, ensuring installations are professionally designed, properly inspected, and compliant with safety standards will be crucial in protecting consumers and preserving the reliability of the country’s power system.
