🇹🇭 Thailand was once a solar energy pioneer of Southeast Asia, but in recent years, capacity growth has remained fairly flat.
🔍 Now, the rooftop solar market is back in focus as the government pushes a ‘Quick Big Win’ package to accelerate deployment, especially of residential systems...

4️⃣ Our estimates of distributed solar in Pakistan can be viewed at the national, regional, or sectoral level — or mapped by hexagonal cells in detailed visualisations.
3️⃣ We then used building and land-cover data to link solar patterns to building size and agricultural land.
These relationships let us extrapolate the amount of solar found in our image samples to a total capacity for across Pakistan — from city rooftops to rural fields

2️⃣ Using a mix of machine learning and manual checks, we identified and labelled every rooftop and ground-mounted installation visible in our set of sample images — which amounted to more than 27,000 solar sites.
1️⃣ We divided Pakistan into thousands of small hexagonal cells, then selected around 1,000 representative locations.
Each one was covered by highly-detailed satellite images that can capture features as small as 30 centimetres across, covering both urban and rural areas.

But tracking small-scale solar across an entire country isn’t easy.
