Series-connected shaded modules to address partial shading conditions in SPV systems
AIP Conference Proceedings, 2016With the progress of technology and reduced cost of PV cells, the PV systems are being installed in many countries, including India. Even though this method of power generation has sufficient potential but its effective utilization is still lacking.

MPPT Algorithm Under Partial Shading Conditions
2012This paper proposes a novel maximum power point tracking (MPPT) algorithm based on analyzing the output characteristics of PV array under uniform irradiance and partial shading conditions (PSC). The algorithm adds partial shadow judging conditions in variable step perturb and observes (P&O) method.

Distributed MPPT control under partial shading condition
2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016The performance of series connected PV panels significantly limited by the current mismatch caused by the partial shading. Distributed maximum power point tracking can increase the overall efficiency. A module level and a string level sub-module integrated maximum power point trackers are presented in this thesis.

Efficiency improvement of partially shaded photovoltaic panels
2013 European Conference on Circuit Theory and Design (ECCTD), 2013Layouts of domestic photovoltaic solar plants can be problematic due to obstacles that shade panels. This limits the total available area and, if not adequately considered, can deeply affect the efficiency of the plant. In this paper, a circuit that recovers generated power efficiency when a small number of cells of a panel are partially or totally ...

Subcell Modeling of Partially Shaded Photovoltaic Modules
IEEE Transactions on Industry Applications, 2019Increased photovoltaic installations in densely built-up areas give rise to non-uniform irradiation causing partial shading. Non-uniform irradiation further leads to non-uniform temperature, leading to a reduction in output and the formation of deteriorating hotspots.

Performance enhancement of partially shaded solar PV array using novel shade dispersion technique
Frontiers in Energy, 2016Solar photo voltaic array (SPVA) generates a smaller amount of power than the standard rating of the panel due to the partial shading effect. Since the modules of the arrays receive different solar irradiations, the P-V characteristics of photovoltaic (PV) arrays contain multiple peaks or local peaks.

Effect of Partial Shading on Photoproduction of Hydrogen by Chlorella
Journal of Bioscience and Bioengineering, 2004The photoproduction of hydrogen by the green alga Chlorella pyrenoidosa was studied in 650-ml bubble columns made of glass with 7 cm diameter. Hydrogen was produced by adding sodium dithionite as an oxygen scavenger directly to an algal suspension. When a part of the wall of the bubble column was shaded with a sheet of plastic film impervious to light,
