Team Digit | Published on 09 Mar 2021 Renkube Private Limited, one of the Startups associated with the Nexus Startup hub has come up with an innovative solution that allows for optical tracking of solar panels, without having to use servos and motors to keep the panels aligned to the Sun. Instead of flat solar panels, Renkube creates panels with its patented technology, that use a series of grooves to guide the photons to the solar cells, resulting in a 20 percent rise in electricity generation, while at the same time having no moving parts. We spoke to Renkube to better understand their innovation.
