Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions
Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

Optimal operating point tracking in a stand-alone PV system using particle swarm optimisation
In this paper, particle swarm optimisation (PSO) technique is employed to determine the optimal operating point of a photovoltaic module used in a stand-alone PV system. The PSO algorithm identifies the maximum power point by determining the array voltage at maximum point (VMPP). This value is utilised as a reference value to a voltage controller to adjust the duty cycle of a boost converter such ...

Global maximum power point tracking for partially shaded PV arrays using particle swarm optimisation
This paper introduces a global maximum power point tracking (GMPPT) method for a group of photovoltaic modules connected in series and operating under different levels of solar irradiation using particle swarm optimisation technique. Partially shaded PV modules produce several local maxima power points, which makes the tracking of the global maximum power a difficult task. Most of traditional ...

Efficiency improvement of a photovoltaic system by acting on the characteristics of MPPT control
A 360 W photovoltaic (PV) module power with a maximum power point tracking (MPPT) algorithm is analysed and presented. In this study, the control algorithm is improved and then applied to the PV system. The results obtained show the ability of this algorithm to control high powers when weather conditions are changing. Under the same conditions, this improved technique offers, in steady state ...

MGM makes transformers for solar applications
Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century. Increasing ...

Applicability of Equivalent Diode Models to Modeling Various Thin-Film Photovoltaic (PV) Modules in a Wide Range of Temperature and Irrandiance Conditions
Abstract In the paper results of fitting of current-voltage (I-V) curves acquired in a wide range of irradiances and temperatures with use of equivalent either single (SEM) or double (DEM) diode model as applied to several commercial thin-film photovoltaic (PV) modules are presented. It is shown that like in case of crystalline silicon PV modules also for CIGS (CuInGaSe2) as well as CdTe ...

Test Sites And Testing of 3-Sun Mirror Modules
ABSTRACT The demand for solar photovoltaic cells and modules has far outstripped PV cell supply and module prices are rising. To solve this problem. JX Crystals is developing a 3-sun mirror module that uses 1/3 the cell area to triple module production at a lower cost. Our concentrator module design uses existing planar cells. We simply cut standard SunPower A300 cells into thirds. In addition, ...
