A technically valid, advanced and economically competitive product, designed by COMAL Impianti srl.
The Comal "Sunhunter 18AB" horizontal single-axis system is easily adaptable, thanks to its flexibility, to the configuration of various photovoltaic fields, in order to achieve the goal of maximizing the power that each individual field can generate. The use of trackers of different length and the ability to independently set the angles of each tracker, even at the end of back-tracking, allows you to achieve the aforementioned goal.
The Tracker is characterized by two components: the structural component and the electronic component.
