ABOUT SPECTRUM
SPECTRUM is a proprietary model and web platform developed by the Institute for Climate and Sustainable Cities (ICSC). It allows users to visualize rooftop solar installations and estimate potential solar capacity across the Philippines.
The platform’s name reflects its use of multi-spectrum satellite imagery—including infrared and visible light bands—to detect solar installations. By analyzing high-resolution images (30 cm to 50 cm), SPECTRUM automatically identifies solar panel systems and calculates their capacity, enabling smarter, data-driven energy planning and policy development.
SPECTRUM SERVICES AND SOLUTIONS

AI Powered Detection
AI Powered Detection
Proprietary machine learning models identify solar panels in satellite images.
Capacity Estimation
Capacity Estimation
Estimates capacity using a standard ratio: 1 megawatt per hectare (10,000 sq m) of detected solar panel area.
Localized Insights
Localized Insights
Aggregates results at the municipal, city, utility, and provincial levels to support energy analysis and planning.
PROTECTING USER PRIVACY
While SPECTRUM maps and estimates the capacity of detected solar PV installations, it does not share raw vector polygon data or exact site coordinates, as these could serve as proxies for addresses. Instead, only aggregated capacity estimates are shared and made available for download at the barangay, municipality or city, and distribution utility levels.
