Highway to winning PV proposals

You're about to finish the last iteration of the electrical and cable listing of your PV project just in time for the deadline. You've got mail! Your colleague Anna, from the procurement team kindly suggests you to try out a new and incredible inexpensive PV modules. She attached the .pan file. No excuses. You have to re-do most of the job and report back the CAPEX analysis. Long day ahead.


Meet the most detailed basic engineering ever

Engineers spend too much time doing repetitive tasks. We know it because we've been there. We know the feeling of being a mechanical turk.

Imagine a team where Anna's request got done in a bliss. Keep your solar LCOE tight by minimizing engineering and construction plant costs.

With pvDesign, you just upload the equipment file, adapt and customize your input. Get 300+ pages of technical docs, including the cost analysis and energy yield simulation, in minutes. Export a CAD-ready file for polishing the last details. And call it a day.

The bigger, the better

The bigger, the better

Unlike one-size-fits-all apps, pvDesign's algorithms are coded for you to get a highly accurate outcome for 1+MW ground mounted PV plants.



Empower your engineering teams to carry out feasibility analysis and plant designs. Avoid outsourcing these tasks and save money.

Substation engineering

Substation engineering

Tailored for solar PV

Tailored for solar PV

By gathering accurate irradiance data, the LCOE for your ground-mounted PV project is solid.

300+ pages of engineering in two minutes

The design interface guides you through the steps to get your plant proposal documents. Rely on algorithmic calculations or fine-tune their results to get your desired outcome.

Lightning fast layout

Get a new design from scratch in minutes —including required earthworks. Or clone an existing one and compare them in a matter of three clics.

  • pvDesign calculates the volume of earthworks required to install a structure

  • It works along with the topography analysis to achieve better compliance with the terrain.

  • Get accurate energy yielding and cost estimates.

Like Alexandria, but with solar

Use the always up-to-date 7,000+ equipment library built in pvDesign to get a well founded PV layout effortlessly.

  • Mono and bifacial modules

  • Thin films modules (CdTe)

  • Central and string inverters

  • Privately upload your own equipment files

Detailed engineering, powered by algorithms

Once your design is fully optimized, pvDesign delivers a handful of documents of PV detailed engineering. Including single line diagrams (SLD) for the interconnection facility. Both in PDF and editable formats.

  • 3D layout and terrain slopes

  • SLD for medium, low and medium-low voltage.

  • Structure profiles

  • Substation layout and SLD

PV CAPEX at a glance

Use the default cost templates or customise them to get a CAPEX and LCOE analysis of your PV project in seconds. Just input the unit price. The hassle of finding the number of required equipment is on us.

  • Adapt costs categories to fit your clients requests.

  • Input OPEX and effortlessly get CAPEX in your currency.

  • Download your custom CAPEX analysis in an editable spreadsheet.

Long-range energy yield

Get up to 50 years of energy yield of your plant design using your meteorological, horizon and albedo data. Or use our out-of-the-box data sources.

  • PVGIS 5, NASA Power and SSE sources included.

  • Input PV module and PV plant losses and understand how it impact energy yield.

  • Choose your preferred IAM loss model for PV modules.

The first paperwork you'll love

Download a whole pack of engineering documentation for your project. Including BoQ, design drawings, list of cables or electrical diagrams. Ready to cast to your off-taker or EPCist.

  • Design, energy yield and interconnection facility reports.

  • Project sheet, bill of quantities, listing of cables in spreadsheet format.

  • SLDs and 3D facility layout ready to import to PVsyst or your CAD software.

Works with earthworks

The earthworks feature works in combination with the topography analysis to achieve better compliance with the terrain and more accurate cost estimates. Get a handy .csv file with your topography analysis after applying cut and fill earthworks.

  • Earthworks calculation per structure

  • Also, automatically compute required earthworks to flatten the substation area.
