Solar Trackers
Wherever the Sun Is.
The solar tracker exploits the energy of the sun, transforming it into electricity. It does this so intelligently that, just like the sunflower, it turns to continually face the sun. This ensures that the sun’s rays are always shining directly upon the solar modules, which in turn guarantees the highest possible power yield. In the face of this, the energy needed to drive the two small motors which position the modules fades into insignificance when compared with the extra energy gained.
It has been shown that the annual yield of a solar tracker can be 35-40% higher than a standard, rooftop-mounted static photovoltaic array.
The effective output of a solar tracker in the solar park am Peterswald | Neuental is around 8.1 kWp. This allows for an annual power generation of around 10,585 KWh. Each solar tracker produces enough electricity to cover the average annual energy needs of three families (around 3,000 KWh/year).
Peterswald contains 286 of these high performance solar trees, constructed over a number of project phases.
Alongside the legally-guaranteed minimum income from feeding power into the public grid, solar power profits the environment and is profitable for the investor.
Performance chart on a typical, sunny summer day.
The graph above beautifully illustrates the extra solar yield of a solar tracker. The light blue curve represents the performance of a static, south-facing photovoltaic array on a sunny day. The dark blue shading represents the performance of a dual-axis tracking system. Whereas the optimally-positioned yet static array only achieves peak performance at midday, the solar tracker operates at maximum efficiency from 9am through 6pm.
