The same engineering we put into client tools, packaged as a product.
PVAstraby REY TechnologiesLaunching soon
From site boundary to bill of quantities, in one drawing.
PVAstra takes a utility-scale site from its boundary to arrays, cables, trenches and bills of quantities. Every tool reads what the previous one wrote, so nothing is drawn twice.
Site setup from the boundary: fence, roads and PV areas
1Array Creation, with a live preview before frames are placed
2Frames fill the PV areas, clear of setbacks, roads and shadows
3Strings grouped into combiner boxes, each group in its own colour
4A cut and fill map from grading
5A single-line diagram drawn from the grouping report

Client projects
Tools built for real teams.
Most project clients stay unnamed, and we're happy to share references. Each tool below is built with the team it's for. Client drawings stay private too, so these pictures are our own illustrations of what each tool does.
Solar · rooftop
AutoCAD · C# .NET
Rooftop solar design suite
Engineers at a commercial and industrial solar developer in India draw the roof once. The plugin then lays out the whole rooftop plant and produces the drawings and quantities for construction.
Site from the map, with shadow analysis to the minute
Module placement around obstructions and walkways
Automatic stringing with clean routes
Cable trays with bends, tees and drops
DC cable routing to the inverters
Project summary, BOM workbook and good-for-construction (GFC) sheets

3An earthing layout with its strips and pits
4A module cleaning system with its BOQ
5GFC sheets for construction
Manufacturing
AutoCAD · ARES Commander · C# .NET
QxCAD
QxCAD is a trademark of MYT4 Systems Pvt. Ltd. REY Technologies designed and developed it for them.
A drawing suite that balloons dimensions, notes and finish symbols, works out each balloon's zone and turns the drawing into an inspection report, from one ribbon tab.
