Q.TRIS - solar power puzzle

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.
