How the DIY Solar Layout Engine Works
Planning a self-installed solar project? Most calculators are just marketing traps designed to collect your data. Our Free Solar Roof Calculator is built specifically for the DIY community, providing the technical precision you need to design your own system without the corporate gatekeeping.
Pro-Grade Accuracy for Independent Builders
Stop guessing your panel count. Our engine bridges the gap between your energy goals and real-world physical limits. By mapping your roof dimensions and local irradiance, we help you determine the true maximum capacity of your space. We handle the technical heavy lifting—automatically accounting for fire code setbacks and safety zones—so your DIY planning is solid from day one.
Verified Hardware Databases
For a DIYer, hardware choice is everything. Use our verified database of real-world specs from brands like Jinko, Longi, and Victron to see exactly how specific equipment fits your roof geometry. You get a technical layout report that reflects the actual hardware you plan to buy.
Exportable Blueprints (SVG Format)
A standout feature for the independent builder is our Scalable Vector (SVG) Export. Instead of a low-quality screenshot, you get a clean, professional vector blueprint of your roof layout. It’s ready for your documentation, sharing on forums for feedback, or precise measurements during the physical install.
Unbiased Data, No Sales BS
Global Sun Hub is a 100% independent project. We don't sell leads to installers, and we don't push specific brands. Whether you’re building a tiny off-grid cabin or a full residential array, you get an honest, data-driven picture of your solar potential and estimated ROI—built by developers who believe in energy independence.
