40.8 Tracking and Concentration Systems
In 1982, I measured on the roof of Altamarena that the energy
production was increased by 20–25% when the modules were
automatically directed to the sun, following the sun’s inclination, and
I started to construct the first tracking systems with four sensors
around a square pole. It was running well initially, but mechanical
problems stopped the application (Fig. 40.16).
One other question was how to concentrate direct radiation onto

working with Fresnel lenses or mirror systems. In praxis many
problems stopped these applications. ...
