The development of VectHor technology began in 2019 with the creation of an initial concept featuring east-west vertical bifacial solar panels paired with horizontal reflectors (TRL 2). The first prototypes were designed and rigorously tested at the IMN-CSIC experimental solar facility to ensure thorough validation of their performance.
In 2020, the first experimental proof of concept (TRL 3) was successfully built, followed by multiple iterations of prototypes with varying configurations, which were tested and validated at IMN-CSIC between 2020 and 2022 (TRL 4-5).
A key milestone was achieved in 2023 when a preliminary version (TRL 6) of the VectHor system was deployed on the rooftop of CSIC. This setup resulted in a 33% higher annual energy yield compared to a conventional 30º south-facing bifacial solar system, clearly demonstrating the efficiency and energy production advantages of VectHor technology.
