  • Technical Note: Loss-of-load probability of stand-alone solar photovoltaic system

    In this technical note, a general method has been given to determine the loss-of-load probability (LOLP) of a stand-alone photovoltaic system as a function of normalised PV array output and energy availability at battery. The energy availability at the battery has been determined by using the solar radiation utilisability concept. To determine the LOLP, the PV array output is required, which is a ...

  • Photovoltaic string disconnect switches

    PV system arrays generate DC current. The solar modules are wired in series, and the system voltage is the sum of the maximum output voltage of all of the modules in a string. 600 Vdc maximum was chosen as an optimal system voltage to reduce installation costs by reducing conductor size and to stay below the 600V threshold in NEC Article 490. Prior to the growth in the number of installed PV ...

  • Performances of photovoltaic water pumping systems: a case study

    This paper presents a mathematical motor-pump model for photovoltaic (PV) applications which allow us to contribute in the studies of PV pumping sizing. The modelled motor-pump characteristic is flow rate-power (Q, P). The model is established for centrifugal pump (CP) coupled to DC motor. The non-linear relation between flow rate and solar power has been obtained experimentally in a first step ...

  • Photovoltaics Energy Technologies

    Technology Overview    Photovoltaic (or PV) cells are devices that use semiconductor materials—similar to those used in computer chips—to convert sunlight directly into electricity. The electric current can either be used immediately, or it may be stored, as in a battery, for later use. A typical PV or solar cell might be a square that measures about 4 ...
