Aerial imagery layout
Place panels on high-resolution imagery with Nearmap and Metromap support for crisp, current rooftops.
Solar Proof is solar design software for Australian installers. Place panels on high-resolution aerial imagery, run shade simulations and let auto-stringing configure multi-inverter systems for you, producing accurate, buildable PV designs with no CAD software to install.

What is solar design software?
It lets installers lay out panels on a roof, model shading and sun exposure, and configure inverters and strings to estimate production. It turns a site into an accurate, buildable design.
Does it support multi-inverter and multi-MPPT designs?
Yes. Solar Proof supports both, and auto-stringing assigns panels to strings and MPPT inputs automatically while respecting voltage windows.
Do I need CAD software?
No. Solar Proof runs in your browser, you design on aerial imagery and generate SLDs without AutoCAD or any desktop install.
How accurate are the production estimates?
It uses an industry-standard simulation with shading, orientation and tilt factored in, and applies honest loss figures rather than inflated numbers.
