Abstract
Stationary flat plate and tube collectors that do not require solar tracking system have been used more every day for various applications. An alternative to these conventional collectors is the use of the V-trough and parabolics collectors. They concentrate the received radiation in its focus. If it is combined to solar tracking systems, provides greater solar radiation absorption than flat plates collectors. In this study algorithms are implemented in order to enable the timed command of the solar or radiation sensors tracking systems viability. The tracking system was simulated and implemented following the methodology used by Duffie (1991) and Beckman (2006). In other simulation, light sensors were used for a tracking system. The obtained results from the two models were compared. The results obtained from the LDR sensors blur the collector due to the interference from other light sources. The adjustment with solar geometry equations depends heavily on a clock coupled to the integrated circuit. Besides the sunlight, tests with the set LDR sensors in the focus will be performed.
