French startup offers ‘manual’ solar tracker for residential PV systems


From pv magazine France

French startup Luciole & Basilic has developed a tracker for residential PV installation that can reportedly offer a 12% higher energy yield.

“The principle is simple,” the company's founder, Nicolas Ditleblanc, told pv magazine France. “We have developed an adjustable fixing system associated with an application, called Zenitrack, which indicates the optimal angle of inclination of the solar panel facing the zenith throughout the year.”

PV system owners can slightly modify the angle of their solar panels every two weeks, so that it always faces the sun. They can move the structure manually by using a telescopic rod.

“We have utilized the function of a power grip, which is a handle used in sailing to precisely adjust the length of a telescopic tube,” said the inventor. “Thanks to a graduation system, the user can modify the inclination of his solar panel, between 15 degrees and 80 degrees, to follow the zenith.”

Ditleblanc claims that the system can increase the electricity yield of solar panels by 12% over the course of a year.

“We compared a 1 kW system on a fixed roof oriented at 30 degrees and a 1 kW Zenitrack system placed on the ground in a garden,” he explained. “During the summer months, the difference is minimal, but during the winter months – when production is low and the household's electricity consumption is at its maximum – our adjustable device allows gains of 30% to 50% compared to a fixed installation.”

The April issue of pv magazine, which hits the streets today, takes a look at how the long-established link between solar and cannabis cultivation can help improve margins as medicinal and recreational use of the drug comes out of the weeds. We take a trip Down Under to examine why communities are rebelling against planned renewable energy zones perceived as being railroaded through without sufficient local consultation, and we consider the “solar crime” wave sweeping the UK and Europe.

The system can be used with any solar panel up to 1.20 meters wide. Production of the first prototypes has already begun.

“Our structure is aimed at small residential self-consumption, with one, two or even three panels and we would like to sell it below €170 ($186) including taxes,” said Ditleblanc. “We are currently looking for distributors across Europe.”
