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 ...

Albedo measurement for bifacial PV modules
Over the last year Kipp & Zonen has received a lot of questions about albedometers from customers working in the Solar Energy market. These came from engineers and researchers working with bifacial PV modules. Bifacial simply means that the back of the PV module has a glass panel, instead of an opaque metallized backing, and can collect light and generate electricity from both sides. This ...

Microhydro Evolution - Installation of a Low Head Hydro System
Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system. The reading determines whether we use the propane stove or the electric jug to heat water for our tea. Since our microhydro plant upgrade, it’s usually the jug. ...

Genetic Algorithm optimisation of stand-alone Photovoltaic energy systems
This article presents the methodology for calculation of the optimum size of a Photovoltaic (PV) system. Long-term data of PV radiation were used to calculate the average power generated by a PV generator for every hour of a typical day in a month. A load of a typical house in the south of Algeria (desert area) was used as a load demand of the system. For a given load and a mixed multiple ...

Demonstration of a 33% efficient Cassegrainian Solar Module
Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual junction ...

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 ...
