In development
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 today
- 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
Coming soon
SunCetra Design is still being finished. When it's ready to sell, it'll work the same easy way as Energy Monitor: a free 7-day trial with the full app unlocked, then a one-off license key by email of its own — no subscription, no account required.
There's nothing to buy here yet — check back, or see Energy Monitor if you'd like to try what's available today.
