A bankable alternative to PVsyst

You can mitigate risks from PV projects with an accurate and trustable energy yield. Having an embedded design and engineering software within your EY tool helps you observe how changes in the PV layout affects production, CAPEX, OPEX or LCOE.

We turned to market-leading engineering firm Black & Veatch to compare pvDesign’s energy yield module to PVsyst output in four real-life cases. Deltas range between +0.24% and +1.08%. Related detailed yielding documentation is available in both tools.

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.

Compare multiple designs

Streamline your decision-making process by using our comparison tool. This will help you compare different designs of a project side to side using your preferred parameters and even compare them in charts.

Get the power factor methodology

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.

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.

Run your design's shading scene in PVsyst

Export to PVsyst

Get a much faster and accurate energy yield estimates within PVsyst from your pvDesign projects by exporting the shading scene in .pvc format.

  • Quickly generate an accurate 3D shading scene in PVsyst. The scene considers the shape of the perimeter, the terrain features, and the presence of adverse slopes from your project in pvDesign.

  • Get accurate energy simulation results. Including the 3D features of the terrain and positioning of the structures.

  • Evaluate the effects of topography restrictions. Detecting areas which require changes to the design, such as north-facing slopes which could require increasing the pitch.

Watch testimonial

We use RatedPower to compare performance of our equipment. Our customers usually ask us «Should I use string or central inverter for this PV plant?» It's pretty tough to say something about it without taking into account a lot of parameters that your engineering team have to analyze case-by-case. RatedPower helps us speeding up this.
