The paper describes a new kind of solar tracker intended to satisfy the precision requirements of high concentration photovoltaic systems. The tracker is designed according to a Delta type parallel kinematic schematics. The paper describes the kinematic schematics, the sensor chain and the control algorithm. Finally results obtained in functional tests are shown.

Southern Nevada Water Authority

The Southern Nevada Water Authority contracted with Amonix, Inc. in 2008 to procure 220 kWdc of their latest generation multi-junction cell High Concentration Photovoltaic systems (HCPV). This paper discusses the performance of the six HCPV systems that started operating in mid 2009. Data sets included show: a. Daily power performance; b. Power performance compared to the specified performance; c. Effect of field shading upon the daily power performance. What is demonstrated is the system power performance has not degraded during this initial period of operation and continues to meet or exceed the specified performance levels.

This paper presents the design and development of a new flexure-based compliant XY micropositioning stage with large stroke. The parallel-kinematic XY compliant stage is designed based on the Roberts mechanisms. Pseudo-rigid-body model is developed to establish the quantitative models of the whole compliant mechanism. Finite element analysis is carried out to validate the performance of the XY stage. A prototype of the XY stage is developed for experimental investigations. Experimental results show that the stage can deliver a working range larger than 12 mm in each of the two working axes. Moreover, a feedback control using the proportional–integral–derivative control algorithm is implemented to demonstrate the positioning performance of the developed XY stage. The reported ideas can also be extended to the design and control of other micro-/nanopositioning systems.
