English Abstract
The production of the Photovoltaic (PV) system can vary proportionally to sunlight intensity striking the surface of the PV array.
The sunlight intensity changes hour by hour, throughout the year, and shading from other buildings, trees, dust or clouds, will result, which is the main factor that may cause mismatch losses in PV systems.
That means shading of one cell in an array will decrease that cells’ photocurrent which will, consequently, reduce all the cells’ current, and will result in reversal of the cells’ voltage.
This thesis studies the effect of shade on a 288kW PV system installed in Royal Scientific Society (RSS).
The study considers different patterns of dynamic shade; low, medium and heavy shade, different types of inverters; central, string and microverter, and different series and parallel connections of the PV modules.
A comparison regarding the cost is also made, in order to choose the optimal connection for the whole system.
A field test was made for a NU-SOE3E Sharp Modules, to measure how the current and the voltage changes as the module was exposed to different patterns of shade, it was shown that if only one cell is under shade, the voltage drops by third.
The study proved that for a large scale PV system under different types of shades, the output power of string inverters is higher than the output power of microinverters and central inverters.
For a small scale PV system, the output power from microinverter is higher than from string inverters, but the comparison showed that PV systems with microinverters are more costly.
