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%
