Tracking greatly improves the performance of your PV system. Trackers let the PV panels follow the course of the sun, so that the panel surface is always in an optimum angle to the sun rays. This guarantees highest efficiency ETATRACK 400 ETATRACK 1000 ETATRACK 1500 1-axis, active solar tracker total module surface max. 4 m2 approx. 500 Wp maintenance-free, high reliability and life expectancy no failure prone light sensor low power consumption approx. 1.25 kWh per year no unnecessary tracking movements designed to withstand wind speeds up to 120 km/h cost-efficient tracking system 2 years manufacturer's warranty against defects in material and workmanship 1-axis, active solar tracker total module surface max. 10m2 approx. 1.6 kWp maintenance-free, high reliability and life expectancy no failure prone light sensor low power consumption approx. 1.25 kWh per year no unnecessary tracking movements designed to withstand wind speeds up to 150 km/h cost-efficient tracking system 2 years manufacturer's warranty against defects in material and workmanship 1-axis, active solar tracker total module surface max. 15m2 approx. 2.4 kWp maintenance-free, high reliability and life expectancy no failure prone light sensor low power consumption approx. 1.25 kWh per year no unnecessary tracking movements designed to withstand wind speeds up to 150 km/h cost-efficient tracking system 2 years manufacturer's warranty against defects in material and workmanship
