This paper focuses on the comprehensive modeling, simulation and experimental validation for a photovoltaic system formed by monocrystalline solar modules. The performance of the equivalent circuit model for a solar cell is validated by data measured parameters of photovoltaic modules. Also, this paper brings a novel iterative procedure to find the value of diode ideality factor, series and equ...

The objective of this contribution is to present a new numerical approach for a complete design, optimum sizing, cost estimation (capital & $/kWh) and also evaluating the performance of solar photovoltaic/battery/diesel hybrid power systems. The world-wide demand for solar photovoltaic energy systems has grown steadily over the past 15 years. The need for reliable and low cost electric power in...

Maximum power point trackers (MPPTs) play a vital role in photovoltaic (PV) systems because they increase the eff iciency of the solar photovoltaic system by increasing the power output. MPPT algorithms are necessary because PV arrays have a non linear voltage-current characteristic with a unique point w here the power produced is maximum. The output pow er from the solar panel varies w ith sol...

Solar cells and photodetectors are devices that convert an optical input into current. A solar cell is an example of a photovoltaic device, i.e, a device that generates voltage when exposed to light. The photovoltaic effect was discovered by Alexander-Edmond Becquerel in 1839, in a junction formed between an electrode (platinum) and an electrolyte (silver chloride). The first photovoltaic devic...

We conducted an analytic study of concentrated solar photovoltaic and hot water co-generation based on various solar cell technologies and micro channel heat sinks. By co-optimizing the electricity generation and heat transport in the system, one can minimize the cost of the key materials and compare different tradeoffs as a function of concentration ratio or other parameters. Concentrated sola...

Reconfigurable photovoltaic (PV) systems are of great interest with respect to system designers in order to improve the system’s efficiency and operation. This paper proposes an adaptive reconfiguration scheme to reduce the effect of shadows on solar panels. A method to capture the maximum power point of the photovoltaic (PV) array systemwith the help of DC/DC central converter system is presen...
