Photovoltaic Water Pumping — A 1986 Updateght years of practical experience. It is concluded that technical problems have been largely overcome, although because photovoltaic pumps are not yet in widespread use, there is a need for improved routine system selection and provision of maintenance back-up. Photovoltaic pump costs are currently

The Calibration of Primary Terrestrial Flat-Plate Reference Devices — A Proposed International Standis concluded that an outdoor method in clear, sunny weather, using the diffuse as well as the direct radiation, is most likely to gain general acceptance as an international standard. Such a procedure is proposed for further study.
