In conventional PVS, energy management is performed either in PV arrays or in individual groups of solar cells, resulting in a significant reduction in energy production. A smart PVS is
A solar array begins with solar cells, also known as photovoltaic cells, which are grouped together in order to create solar panels. When multiple solar panels are grouped together to generate electricity, this makes up a solar array. The main function of these arrays is to collect, invert, store, and distribute solar energy for the purpose of electricity generation. Common examples of

The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short. Solar PV systems
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
However, freestanding solar arrays usually require a lot of space. Also, freestanding solar arrays should not be mounted on the ground in areas that receive a lot of snow. Solar array mounts can also be either fixed or tracking. Fixed solar arrays, which are often roof-mounted or freestanding, are preset for height and angle and do not move

The current–voltage relationship for the single-diode model assumes that one lumped diode mechanism is enough to describe the characteristics of the PV cell. This current–voltage relationship is the basis for the mathematical models developed by Desoto et al., 2006, Jain and Kapoor, 2004.
Simulation studies are made regarding the enhancement of total output power generated from a 9 × 9 sized test solar PV array. The performance of the solar PV array subjected to four different defined shading patterns (non-homogeneous irradiation situations) is studied.
Using a bypass diode configuration, electrical output power produced from the solar PV array is about 15 kW, leading to MPL of 15 kW. Thereby, the efficacy of proposed ‘hybrid interconnection schemes’ and ‘external bypass diode connections technique’ is justified for typical PS over 50% of the array.
The proposed model can be applied for PV arrays of any size and is suitable for application in simulation programs such as EMTDC/PSCAD and MatLab/Simulink. A series of experiments were performed outdoors for different configurations of a PV array to validate the accuracy of the model.
