Quezon City rooftop solar capacity jumps 73% in under two years, but adoption remains below 1%

Quezon City's estimated solar capacity rose from 33.85 MW to 58.55 MW between 2023 and 2026, a 73% jump, according to the Institute for Climate and Sustainable Cities. More than 95% of that capacity comes from rooftop systems, which could generate over 78 GWh per year, or about 1.35% of the city's 2025 electricity consumption. The growth is tied to the city's expanded solarization program, private sector installations, and its 2025 Green Building Code. Despite the jump, rooftop solar adoption is still below 1% of buildings. The city's maximum rooftop solar potential is estimated at 4,916 MW, so the current 58.55 MW leaves a large gap. The main challenge is expanding access to households, socialized housing, and small businesses, not just malls and public buildings.

Good to see actual numbers from a detection platform instead of just project announcements. The 73% jump is real growth, but the 1.35% of city consumption part shows how early this still is.

58.55 MW estimated total with 4,916 MW potential. That gap is enormous. I would like to know how much of that potential is actually viable after accounting for roof condition, ownership, and distribution grid limits.

The Green Building Code requirement is the interesting lever here. Mandating solar or efficiency on new and renovated buildings changes the baseline. But adoption below 1% suggests the code has not reached existing households yet.

Worth noting that malls like SM and Ayala are carrying a big share. That is good for capacity but does not help low-income households. The article says access is the issue, and that is the part that needs policy follow-through.

The 78 GWh annual output number matters more than the MW figure. That is actual energy replacing grid power. If they want households in, financing and permitting will decide it, not just the building code.
