Amid Power Crisis, Samal’s LGU Turns to the Sun, as Mindanao slowly Goes Solar

 

In the final days of his term, Mayor Al David Uy stood with us beside a shaded column of the Island Garden City of Samal City Hall’s new parking bay, a structure that, under any setting, might appear ordinary. But here, its rooftop holds more than 1,000 solar panels.




“We’re known as an eco-tourism destination,” he said. “Yet it’s embarrassing to admit that we still rely on a diesel power plant.”


Samal’s situation is one familiar to many Philippine islands; blessed with natural beauty and abundant sunshine yet troubled by an outdated energy infrastructure. Until a decade ago, Samal drew its electricity from a submarine cable connected to the Davao mainland. That was before a ship’s anchor severed the line, plunging the island into years of rotating blackouts, unkept promises, and delayed progress.


Now, with a diesel plant supplying less than ideal power supply into an island aspiring for sustainability, the city government has decided to take its energy future into its own hands.


Power from the Roof


Earlier this year, the city inaugurated the 50-million-peso Samal Renewable Energy Project, transforming the roof of its new 190-car municipal parking building into a solar farm. The project, financed by a Landbank loan and implemented by Greenergy Development Corporation, came not as a grand ribbon-cutting event, but as a necessity that is long overdue.


Power from the roof

The system was built with over a thousand solar modules rated at 450 watts each, now powers the entire city hall, covering its daily 250-kilowatt demand and generating up to 450 kilowatts on a clear day. In just the first three weeks after its transition in May, the city had already saved more than 200,000 pesos in electricity costs. “That number grows every month,” Mayor Uy said.


City Engineer Matthew Arig believes the return on investment will take just seven to ten years. The grid-tied system, supported by a 500 KVA inverter, allows Samal to feed excess energy into the public market and other government buildings or even sell it back to the traditional grid power company.


A Slow Heading to Renewable Energy But A Growing Movement


Samal’s experiment with solar is not the first on the island. The Department of Education’s data center made the shift back in 2021, after its servers suffered repeated shutdowns during brownouts. “The rotating brownouts and the birds nesting on lines used to trip the system,” said Kevin Milo, the Schools Division’s IT officer. “Now, we run on a hybrid system. We are even looking to expand.”

Their 5.5-kilowatt hybrid system, part off-grid, part tied to the utility, now ensures uninterrupted power to critical education infrastructure. It’s a small win, but a sign of bigger things to come in Mindanao.


A Region Dealing with Power Supply


Even as Luzon and the Visayas slowly move forward with energy development, Mindanao still lags behind in generation capacity. Power supply is unsteady. Diesel, expensive and dirty, remains the fallback for many islands and isolated towns.


But advocacy groups like Mindanao Goes Solar are shifting that narrative. Backed initially by the European Climate Foundation, the group, the advocacy arm of Cagayan de Oro-based Professional Organizers Unlimited Inc., has become a leading advocate in the renewable energy industry. Their annual Solar Expo, partnerships with local government units, and efforts to connect solar firms with underserved communities have laid the groundwork for a solar ecosystem in the region.

“Solar is abundant in the Philippines. And now it’s the cheapest source of energy, not just here, but in most parts of the world,” said Philline Donggay, the group’s project head. “It’s the most logical solution to kickstart Mindanao’s energy transition.”


Their early mapping studies identified bottlenecks: disjointed policies, lack of provider trust, and scarce access to financing. Despite the difficulty in opening the minds of many to the advantages of renewable energy, the payoff is clear, energy independence, cleaner air, and long-term savings.


“The theory of change,” Donggay explained, “that Mindanao Goes Solar becomes the primary communicator and knowledge-sharing innovator for solar-related information in Mindanao.”


A Model for Other Islands


For places like Siquijor and Palawan, both heavily dependent on costly and polluting energy imports, Samal’s rooftop transformation offers a working model. Even Samal’s beachfront resorts including Pearl Farm and Discovery Samal are taking notice, amd are now considering solar integration not only for sustainability, but also for operational reliability.


And there are broader implications. Net metering policies, where excess power can be sold back to the grid, make grid-tied solar systems particularly viable for government buildings and commercial establishments alike. They also require less upfront equipment compared to off-grid solutions, making them more accessible in a region where funding for solar energy is often tight.


A Solar Future, Still Forming


As the sun sets, Samal’s solar panels take in the last light of the day. It's an image mirroring the hope of many in Mindanao: that the island’s brightest days may still lie ahead.


From government offices to classrooms, from advocacy desks to the rooftops of parking buildings, a transformation is underway. One that’s not just about power, but about empowerment. Mindanao isn’t there yet. But it’s getting closer. Panel by panel. Roof by roof. Island by island.
