Rotem Ventures Incubator
Eternegy has developed a unique, green and cost-effective state-of-the-art dual-axis solar-tracking technology which improves reliability and dramatically reduces costs. We call it “Surfing the Sun”.
Our cable-control technology is the result of a marriage of between kite-surfing, architecture and engineering. The result is a light-weight, low material cost and highly robust solar tracker.
Our sophisticated dual-axis engineering, mechanics and astronomical algorithms make sure that valuable PV modules are kept directly facing the sun all year round.
Our revolutionary design is more robust and lighter than competing products whilst requiring 50% less steel and concrete than traditional tracker designs. It is a utility-scale PV IRR maximizer.
Eternegy Ltd., located in Israel, has been part of the Maayan Ventures Incubator since 2010. A pilot system is in the final stages of installation and will be producing electricity commercially in 2011. Eternegy Ltd. is in the process of a second fund-raising round.
Eternegy has patents pending across the globe including the USA, EU, China, Brazil and India.
Eternegy ETracker Introduction:
The Eternegy ETracker is a dual-axis tracker for the utility-scale PV industry. The ETracker uses an innovative approach to ensure that costs are minimized and robustness is maximized. It provides leading dual-axis functionality at a price that is considerably lower than traditional dual-axis trackers. The Eternegy ETracker has been carefully designed to keep installation complexity to a minimum and has been tested for sub-component reliability and robustness.
The Eternegy ETracker is a very large tracker with a panel platform of 100m². It uses steel cables to simultaneously support the tracker structure and to orient the PV panels towards the sun. The tracker design is a marriage between kite-surfing and tensegrity-architecture. The cables, which are kept under constant tension by winches, allow for multiple PV platform attachment points which increases robustness and wind-resistance compared to traditional tracker designs. The use of cables also means that that the entire tracker structure is much much lighter requiring 50% less steel and 50% less cement than traditional designs. Lower costs and better performance mean that ETracker PV project IRR is maximized.
Introduction to Eternegy:
Built upon our experience working at the front line of large-scale solar field development we have come to understand the challenges involved.
Utility scale PV fields can be projects of enormous size. Designing, developing and building them is a complex task that requires constant balancing of project cost and field performance. Eternegy has made a commitment to increase utility-scale solar field performance whilst lowering costs.
There are many variables that can affect PV field performance such as location, the type of PV panel, weather patterns, component reliability and whether or not the panels are mounted on solar trackers. One of the most effective ways of improving performance is through the use of solar trackers. Dual-axis solar trackers can increase electricity production by as much as 40% over fixed PV panels by ensuring year round alignment with the sun.
