Opsun releases free tool to realistically estimate “extra” yield from bifacial solar panels

Bifacial sun rack company opsun today unveiled a free online tool that provides realistic estimates of the yield of bifacial solar panels on flat roofs — opsunizer.

“Bifacial solar panels have been around for a while, but solar developers and investors are struggling to understand their added value. The Opsunizer is a simple estimation tool that quickly compares monofacial and bifacial systems. This should help developers understand if and when it pays to use two-sided solar panels on a flat roof,” said Tyler Stewart of Noir3 Energy, a Texas commercial consulting firm.

To accurately assess the value of bi-sided solar panels on a flat commercial roof, a property developer must solve a threefold equation: an estimate of the additional profit produced by bi-sided solar panels versus the tilt angle, quantity and layout of the panels versus financial returns of each option at the cost of each different project (in $/W).

Comparing different tilt angles and layout scenarios with their own power generation and costs was possible in the past with cost-effective software such as PVSyst, but it was a long and tedious process at best. The Opsunizer provides a fast and fully integrated solution to all of the above challenges. Using years of testing and monitoring of commercial bifacial solar projects, Opsun has developed a tool that unlocks the knowledge needed to understand the added value of bifacial solar panels when installed on Opsun’s bifacial-optimized solar panel rack, the SunRail. SR3.

Working with research centers such as Sandia National Labs and reviewing peer-reviewed papers and documentation from bifacial solar panel manufacturers, Opsun has developed software that can generate viable estimates for annual bifacial gains. The Opsunizer thus makes it possible to create and compare different tilt angle and design scenarios for the same roof within minutes. The software automatically generates layouts, bifacial solar panels, additional energy yield estimates and financial return estimates compared to a monofacial equivalent design.

“Finally, bifacial is being made accessible to the people. It’s the tool solar project makers need to design the best and best performing solar system,” said Sébastien Rivard, Director of Sales at Opsun. “Combined with Opsun’s best-in-class racking, the Opsunizer will democratize access to bifacial solar and further contribute to a modern green energy grid.”
