The performance of photovoltaic cells greatly depends on the incident angle of the solar radiation. Their power output can be dramatically enhanced using a solar tracker, which forces sunlight to be incident normally (perpendicularly) to the cells at all times. This paper describes the design of cost-effective solar trackers that are passively activated by the thermal expansion of a low-boiling point liquid. Three possible embodiments of solar tracker are presented and their functional study discussed in detail.

Abstract
The performance of photovoltaic cells greatly depends on the incident angle of the solar radiation. Their power output can be dramatically enhanced using a solar tracker, which forces sunlight to be incident normally (perpendicularly) to the cells at all times. This paper describes the design of cost-effective solar trackers that are passively activated by the thermal expansion of a low-boiling point liquid. Three possible embodiments of solar tracker are presented and their functional study discussed in detail.File in questo prodotto:
