Mathematical Analysis of Solar Photovoltaic Array Configurations with Partial Shaded Modules [PDF]

Trends in Renewable Energy, 2020
Solar-based photovoltaic (SPV) cells produce power from sunlight through the photovoltaic effect. The yield voltage of a single PV cell is small, so the voltage is extended by interfacing PV cells in series arrangement known as PV module or panel. Solar PV array comprises of series and parallel connections of modules in the grid structure with a few ...

Mismatch Loss Reduction in Photovoltaic Arrays as a Result of Sorting Photovoltaic Modules by Max-Power Parameters [PDF]

ISRN Renewable Energy, 2013
Variations in photovoltaic (PV) module current-voltage curves result in a power loss in PV arrays often referred to as mismatch loss (MML). As a means of reducing MML, newly fabricated PV modules are sorted to meet a set tolerance for variation in overall maximum power output with respect to a given module’s rated power.

Resistive loading of photovoltaic modules and arrays for long‐term exposure testing [PDF]

Progress in Photovoltaics: Research and Applications, 2006
AbstractThis paper investigates the feasibility of using fixed resistors instead of active maximum power tracking as electrical loads for long‐term exposure testing of photovoltaic modules and arrays. The method of investigation was to compare resistive versus active loading on two modules for which historic current‐voltage data over time were ...
