What is Solar Pre-Design?

Solar Pre-Design, also known as Solar Preliminary Design, is the first phase in planning a solar project. It involves creating initial drawings and designs using software like SketchUp and BricsCAD. This process gathers data from sources such as Google Maps and site measurements provided by the client to develop a detailed 3D model.

This model helps visualize the solar installation, offering insights into shading, energy production, and financial returns. It is essential for EPC companies to present accurate proposals to their clients.

FAQ

Frequently asked questions

What is solar 3D pre-design?
It is the preliminary design stage: 3D layouts, shading analysis, and energy estimates used for proposals and early planning before detailed engineering.
What software do you use?
We commonly use SketchUp, BricsCAD/AutoCAD workflows, and energy tools such as PVsyst depending on project needs.
Is pre-design enough for permits?
No. Pre-design supports sales and planning. Permit packages and detailed engineering are separate services when you need authority submissions.
What inputs do you need?
Site location, roof or land measurements, target capacity if known, and any photos or drawings you already have.
How long does pre-design take?
Most pre-design packages are delivered in a few business days depending on site complexity and data quality.
