Study of bypass diodes configuration on PV modules

Evaluation of the impact of partial shading and its transmittance on the performance of crystalline silicon photovoltaic modules

“…Power losses are in most cases reduced by adding a bypass diode or blocking diode to the PV module (Silvestre et al, 2009). These results are comparable to those found by Topic et al (2017) and show that on an illuminated surface of 83.3% of the total area of the module, the output power decreases by 7.1W; which represents 5.7% of the power of the module that is not under the shadow.…”

Output-Power Enhancement for Hot Spotted Polycrystalline Photovoltaic Solar Cells

“…The use of bypass diodes across PV strings is standard practice that is required in crystalline silicon PV panels [19]. Their purpose is to prevent hot spot damage that can occur in series-connected PV cells [20][21][22]. Bypass diodes turn "on" to provide an alternative current path and attempt to prevent extreme reverse voltage bias on PV strings.…”

Effects of bypass diode configurations to the maximum power of photovoltaic module

“…In 2009, S. Silvestre et al [6] have studied the P-V characteristics of photovoltaic modules that have different bypass diode configuration including two non-overlapping bypass diodes and two overlapping bypass diodes using simulation approach.…”
