Optimal control of photovoltaic arrays
Mathematics and Computers in Simulation, 2013A high value of the energy conversion efficiency is not the only feature a photovoltaic power processing system must have. An optimal control of the photovoltaic generator must be also designed in order to maximize the electrical power it produces, even in presence of a time varying irradiation level or when a part of the photovoltaic source is shaded.

A Photovoltaic Array Simulator
International Journal of Solar Energy, 1982Abstract A system simulating the output voltage-current characteristics of a photovoltaic array is described. The simulator may be used to test the performance of PV arrays and associated power conditioning equipment necessary for the autonomous or interconnected operation of photovoltaic energy sources. The simulator's main features include simplicity

Simulation of large photovoltaic arrays
Solar Energy, 2018Abstract Large photovoltaic arrays are becoming common as the world moves to replace fossil-fuelled electricity generators. As the array size and project cost increase, it becomes increasingly important to know accurately what the array’s performance will be before it is built.

Over the past five years, the cost of solar panels has dropped drastically and, in concert, the number of installed modules has risen exponentially. However, solar electricity is still more than twice as expensive as electricity from a natural gas plant. Fortunately, wire array solar cells have emerged as a promising technology for further lowering the

Photovoltaic array loss mechanisms
Solar Cells, 1986Loss mechanisms which come into play when solar cell modules are mounted in arrays are identified. Losses can occur either from a reduction in the array electrical performance or with nonoptimal extraction of power from the array. Electrical performance degradation is caused by electrical mismatch, transmission losses from cell surface soiling and ...
