A Survey of External Feature of Solar Cells in Partially Shading

Abstract:

Existing model of solar cells is not suitable for partial shading condition, which makes output current-voltage (I-V) curve of photovoltaic (PV) array staid-stepping. Furthermore, Power-Voltage (P-V) characteristics may exist more than two local peak value in partially shading which bring interferences to maximum power point tracking (MPPT). Based on modified engineering model of solar cells, an accurate model of array was proposed considering variation of shadows. And the I-V characteristic, P-V characteristic and yield of PV modules were analyzed. At last, the optimum output power with different shadows arrangement was discussed.
