    solar product spotlight: tracking systems
 Tracking Systems
An advanced mounting system for photovoltaic panels, solar trackers maximize the sun’s energy by tracking its progress across the sky. Versatile enough to provide highly efficient solutions for both large and small projects, solar trackers can generate more electricity in the same area as their fixed-tilt counterparts. Below, we explore some of the solar tracking systems available on the market today.
