“…[ 9 ] Another publication, which shows the complexity of shading, focuses on the yield of various PV modules with partial shading in an urban environment. [ 10 ] Furthermore, in a different publication, a simple model for the impacts of shading on the global irradiance on a rooftop was developed by the statistical analysis of around 48 000 rooftops in Uppsala, Sweden. [ 11 ] With the use of the previously mentioned shading tolerability, a comprehensive study of more than 3000 scenarios with the use of the Monte Carlo method and Latin hypercube sampling was conducted.…”

Partially shaded photovoltaic systems operate with nonuniform conditions within the photovoltaic array, which lead to power losses. Module‐level power electronics can potentially improve the performance of such photovoltaic systems. However, the potential performance increase compared to standard string inverter systems is site specific. To investigate this, power optimizer and string inverter efficiency measurements are conducted in the ZHAW indoor laboratory. With these results, simulations are performed for a module‐level power electronics system with power optimizers at every module and a standard string inverter rooftop photovoltaic system. As a performance comparison, the P370 power optimizer and 3500H inverter are used for the module‐level power electronics system and partial shading by a chimney is considered. For the standard string inverter system, the string inverter SUN2000‐3.68KTL‐L1, without the use of module‐level power electronics, is chosen. The results of the annual simulations show a gain of the module‐level power electronics system between –0.9% and 1.4% (14 modules) or –0.2% and 0.8% (13 modules), depending on the position of the chimney. Furthermore, the shading adaption efficiency, a method of quantifying the annual performance for shading situations by applying weightings to a few indoor measured performance values of power electronic components, is described.

“…A shortcoming of integrated PV, including BAPV, BIPV, and VIPV systems is that modules in urban settings can frequently or continuously all day long be subjected to shading caused by structures, such as buildings, poles, antennas, dormers, trees, birds, and even passing objects (dynamic shading). 7 , 8 , 13 , 14 , 15 Shading results in substantial power loss by string mismatch, which can reduce energy yield by 20–25%. 11 , 16 , 17 Shading causes a reverse-biased solar cell that changes power, known as a “hotspot”.…”

“…In particular, when the surface layer of PV cells is covered by shadow, the efficiency of output power drops significantly [7,8]. As such, the P-U characteristic curve of PV power generation is converted into a multi-peak curve from the single-peak curve, under shading conditions [9,10]. Tracking the global maximum power point (GMPP) of the shaded PV process ensures the output power, and also guarantees the PV modules to operate properly [11][12][13].…”

A PV maximum power tracking strategy for shaded conditions, based on an improved slime mold algorithm, is proposed in this research. To verify the superiority of the proposed algorithm, four bionomics algorithms—particle swarm optimization (PSO), tuna swarm optimization (TSO), squirrel search algorithm (SSA), and black widow spider algorithm (BWO)—were compared. The output parameter of the five control algorithms was summarized and analyzed. The adaptability of the algorithms was proven by setting different shading conditions. The simulation results demonstrated that the proposed algorithm possessed short response time, good tracking effect and fewer fluctuations. Eventually, the different algorithms were verified in the HIL+RCP physical platform. The experimental outcomes showed that the improved slime mold algorithm possessed the best tracking effect, with fewer power fluctuations.
