It’s the 21st century. The world is in the grasp of climate change. Everyone is talking about sustainable, clean power sources. Everyone? Not quite! The people of small, idyllic Q.TOWN are not just talking, they’re taking action. They want to switch to solar power right now. Help them and be a pioneer of the energy turnaround!

This Game is a solar system puzzle. The target is to install as much solar systems on flat roofs of buildings as possible and generate green energy.

Move the solar systems over the roof by dragging it with your finger. Rotate them by dragging the blue triangle around the system and double-tap it or tap on the checkmark button to place it on the roof. Make sure it fits the grid and doesn't overlap another system.

If the system doesn't fit change to another one by tapping the double-arrow button. To reach the highscores, it's important that all systems have the same exposure to the sun.
