Solar Motor Sun Tracer ST12SLT 1-axis with backstructure for 12 panels without ground screws, 0114 / ST12SLT

Opis

1 axis or single axis Solar Tracker with accuracy better than 0,5 deg and backstructure for 12 pieces of solar panels dimensions 0,82 m x 1,604 m and weight of 25 kg max each. So together for 20m2 solar panel surface. Suitable for PV panels. Usage at homes: on-grid at roof on houses, trafic signalisations, street light, cottages, small and large powerplants where solar panels are connected in serial and output is connected directly to inverter or an external charging device. Wind resistance is minimal 180km/h. In a Year basis with single axis motor you can get 25% more income of energy compared to a fixed system. Ground screws are not part of this solar tracker package. You can buy them separatelly.

Solar tracker anti-shadowing software function included.

Real energy measurement of two equal solar panels (fixed and motorized)

Three equal solar panels were exposed to the real sun and conversed electrical power was measured. Test conditions:       Solar panels (all):       2160W (producer spec. at AM 1.5) Date:                       July 2009 Time:                       4:00 to 20:00 (sun time) Geo. Latitude:           46° N Weather conditions:   sunny, but not totally clear Results:        Average energy of fixed:               9028.8Wh Average energy of motorized:        14623.2Wh Note: sum of motor energy consumption through all day is 35.5Wh or 0.24% of all collected energy.

Efficiency of motorized panel: 161,6%
