The design and testing of a system for monitoring the availability of solar radiation for interculture

  • S. M. Newman


Details of the design and testing of a system, capable of monitoring the spatial and temporal variation in the availability of photosynthetically active radiation for interculture, are outlined. The system consisted of an array of filtered selenium photovoltaic cells in specially built cosine corrected mounts. A data logger was used to record the output from these cells at preselected intervals in a form easily accessed by computer. The system was tested in a discontinous canopy of pear (var: Conference) and found to be satisfactory.
