Topographic backtracking and irradiance-optimized tracking promise up to 5% increase in performance gain for developers seeking project financing
Terrasmart, a leading provider of solar racking technologies, electrical balance-of-system products, installation services, and project optimization software, announced an endorsement of their proprietary tracking algorithms from DNV as deployable in solar energy analysis workflows. DNV is the world’s leading testing, certification, and technical advisor to the energy sector. The endorsement applies to two proprietary tracking algorithms: topographic backtracking and irradiance optimized tracking, which combined, can offer up to 5% improvement in performance gain.
The third-party validation improves opportunities across the value chain, from developers to asset managers. For developers looking to secure project financing, it allows them to include energy gain estimates in financial modeling and potentially increase the amount of credit received for backtracking.
Topographic backtracking can increase the value of a 25MW project over a 25-year lifespan by hundreds of thousands of dollars. This benefit is realized especially in undulating terrains, and is a significant increase in the eyes of institutions considering financing the projects. As project finances are being evaluated with even more stringency, both algorithms provide an additional competitive edge in the distributed generation market, where third-party verified solutions have been hard to find yet are becoming increasingly important.
“Terrasmart is always looking for ways to raise the bar in solar technologies, and we’re honored to receive an endorsement from such a highly respected firm as DNV,” says Ed McKiernan, President, Terrasmart. “In addition to the recognition, we’re thrilled that the validation provides new opportunities for developers seeking financing, starting with the distributed generation market.”
The topographic backtracking algorithm can increase production gains by 1-3% by minimizing shading losses. To realize this, it considers terrain variation in all directions across the length of each rack and the position of neighboring trackers in addition to real-world site elevation data, the distance between racks and solar position calculations. This algorithm is particularly beneficial for sites with uneven and challenging terrains, which are increasingly common.
“DNV’s technology review of TerraTrak provided valuable independent analysis of the system’s tracking algorithms. For Nexamp, this report adds meaningful confidence in the technology’s performance assumptions, helping strengthen our own independent assessments,” said Stephen Petrarca, Associate Principal Project Engineer, Nexamp.
