Quezon City's estimated rooftop solar capacity grew 73% in less than two years, from 33.85 MW to 58.55 MW, according to the Institute for Climate and Sustainable Cities. Rooftop systems account for 55.88 MW and could generate more than 78 GWh per year, roughly 1.35% of the city's 2025 electricity consumption. The jump follows the city's solarization program for public buildings and private sector installations at major malls. A 2025 Green Building Code now requires green building measures for new and renovated structures, which should push more rooftop solar into the pipeline. Still, adoption is below 1% of the city's rooftop potential, estimated at 4,916 MW. That gap shows the remaining work is in financing and access for households, socialized housing, and small businesses, not just policy targets.
