Vertical Solar Tracking is Superior for Half of the Planet
Solar trackers substantially increase energy output of solar farms.
Over the past decade, horizontal single-axis trackers have become the de facto standard for new solar farms built at latitudes relatively close to the equator. However, their performance declines at latitudes further from the equator due to the sun’s lower trajectory across the sky.
By contrast, vertical tracking – where solar panels rotate around a vertically oriented pole – capture more energy for regions beyond ±30° latitude. At such locations, vertical tracking delivers much higher energy production across more hours of the day than fixed-mount panels, and even more energy and across more months of the year than horizontal trackers.
VajaTrack Finally Solves the Achilles’ Heel of Vertical Trackers
Until now, vertical (and dual-axis) solar trackers have been expensive and vulnerable to failure under strong winds. VajaTrack changes this with our unique Wind-Responsive Technology.
By using our patented passive feathering mechanics and minimal torque design, VajaTrack reduces wind loads by more than 80%, delivering a highly durable and cost-effective solution.
At last, the half of the planet that includes all of Europe and large parts of North America and Asia can unlock the significant benefits of vertical solar tracking in a cost-efficient solution.
Much Higher Energy Production
The increase in energy output for solar farms built with VajaTrack compared to fixed-mount south-facing panels is massive – ranging from +25% to +35% across locations in Europe.
Higher Value per kWh
Compared to fixed-mounted arrays, almost all of the extra energy produced by a system with VajaTrack occurs during mornings and late afternoons/evenings – when the grid really needs the extra energy and when electricity prices are often considerably higher.
Hence, a solar farm with VajaTrack not only generates many more kWh – it also earns a significantly higher price per kWh than conventional solutions. A solar farm with VajaTrack increases its revenue by 30-40% over fixed-mounted panels.
Compared to horizontal trackers, a solar farm with VajaTrack produces much of its extra energy specifically during the cold winter months with lower standing sun – again when grid need and prices are higher.
Thoroughly Tested in Nordic Climate
VajaTrack has been rigorously tested in the harsh Nordic climate of Sweden. It performs reliably in freezing temperatures and naturally sheds any snow on the panels.
Most importantly, it is engineered and validated to withstand hurricane-force winds.
