Array Technologies, a leading provider of solar tracker systems, worked with independent engineering and design firm DNV to study an alternative method to active stowing called passive stowing.

If the world covered every suitable roof with solar panels ... horizontal installations – but if optimal tilt angles or solar tracking was used, the panels could be up to 39% more effective.

Array Technologies, a utility-scale PV tracker supplier, said at the RE+ solar industry conference ... study on the effectiveness of its patented passive wind stow technology.

To make their point, the researchers chose to look into the maximum potential of solar panels—covering every roof in the world with them, to see what sort of impact that might have. To do so ...
