BV conducts independent review on RatedPower’s pvDesign software

Black & Veatch Management Consulting (BV) performed a conceptual level benchmark analysis of pvDesign and Pvsyst on four separate design and technology cases and found that the difference in computations of energy injected into the grid ranged from 0.07 to 1.08%.

The company issued its independent review of RatedPower’s pvDesign software focused on two main areas:

  1. A conceptual level benchmark analysis of pvDesign  and PVsyston four  separate design/technology cases.
  2. A high-level review of pvDesign’s energy production estimation algorithms.

With regards to the benchmark analysis, BV compared pvDesignand Pvsyst simulation results for four different cases modelling power plants that had DC capacities of approximately 100MWdc.

These cases include fixed-tilt and single-axis tracker configurations and monofacial and bifacial modules deployed in Germany, Texas in the US and Spain. The differences between the energy injected into the grid computed by pvDesignand Pvsyst ranged from 0.07 to 1.08%.  pvDesign’s estimates were consistently higher.

Independent review on pvDesign validated previous internal modelling

On the other hand, BV reviewed two of the major algorithms implemented in pvDesign – the computations of solar position angle and the irradiance received on the back face of a bifacial module – for technical accuracy.

These algorithms were also compared to the ones used in Pvsyst. BV believes that both algorithms follow the same general approach in pvDesign and Pvsyst and conform with standard industry practice.

Mario Benneckers, product manager at RatedPower, commented: “We had internally compared our energy model against PVsyst and we knew we were close. BV has helped us validate our previous work and provided further credibility to our energy estimates.”

RatedPower believes that this independent review on pvDesign proves its commitment to providing a trustworthy energy model that its customers can rely on, and that the results proved the model to be accurate and comply with the industry standards. pvDesign will continue working towards a fully global bankability model and expect to become the one-stop suite for solar development.
