SunCetra Design
A desktop tool for sketching a solar panel layout straight onto a photo of your own roof — draw the roof outline, mark obstacles like chimneys and vents, then generate a panel layout and see exactly how many will fit.
What it does
- Draw your roof and obstacle outlines directly on a photo
- Calibrate scale so panel counts and spacing are accurate
- Generate a layout automatically, per roof section or all at once, with per-section orientation
- Move, remove, and rotate individual panels (90° or freehand)
- Zoom, pan, and snap-to-grid for precise placement
- A panel model database for UK/Europe and USA, so sizes match real hardware
