ReStudio · Design and engineering

Engineering-grade design, without the CAD licence

Model the roof, solve the string layout, run the shade study and export a stamped drawing set — in a browser, from the same record the crew will build from.

Why teams switch

The drawing set stops being the bottleneck

Layouts that respect real constraints

Setbacks, walkways, fire paths and string limits are rules, not reminders — the solver will not hand you an illegal array.

Shade study on real geometry

Hourly irradiance against obstructions and neighbouring structures, with per-string loss you can defend to a lender.

Drawings that match the build

Single-line diagrams, layout plans and mounting schedules regenerate the moment the design changes.

Part of the stack

ReStudio hands the crew the same file it priced

The solved layout becomes a bill of materials in ReCart, a task list in RePartner and the as-built baseline ReLink measures against — one geometry, no re-drawing.

Capabilities

Everything the engineering desk asked for

String and inverter sizing

Voltage windows checked against site temperature extremes before you commit to a configuration.

Structural load checks

Dead load, wind uplift and ballast worked against the roof type, flagged before the survey.

Versioned component library

Live datasheets for panels, inverters, optimisers and mounting — versioned, so a two-year-old design still opens.

Revision comparison

See exactly which panels moved between revision four and revision nine, and what it did to yield.

Your drawing templates

Your title block, your stamp, your sheet order, applied to every export automatically.

Import from survey

DXF, KML and drone photogrammetry arrive as editable geometry, not a background image.

“We stopped rebuilding the same quote in three tools. The estimator finishes a proposal before the site engineer has left the roof.”

“The lender stopped asking for a call. Every assumption behind the yield is a link now, so the file answers the question before it is asked.”

Questions

Questions teams ask first

For layout, sizing and drawing sets, no. Most teams keep one seat for bespoke structural details and import the result back into ReStudio as geometry.

Yes. Setbacks, walkway widths, row spacing, string limits and mounting standards are configured once per organisation and applied to every solve.

It runs hourly irradiance against the traced obstruction geometry and terrain. Where a customer supplies a measured survey, we show the delta rather than overwrite it.

A coordinated set: layout plan, single-line diagram, mounting schedule, string map and a bill of materials that matches the drawing exactly.
