THE ANALISYS OF THE PHOTOVOLTAIC AND ELECTRIC PARAMETERS OF A COOLING HYBRID SYSTEM. CASE STUDY
Journal Title: Journal of Sustainable Energy - Year 2017, Vol 8, Issue 3
Abstract
The paper presents the interdependence between photovoltaic and electric parameters of a solar thermoelectric cooler. It emphasises the importance of the solar radiation during two experiments made in the same day, in different weather conditions. Also, it is shown that while the photovoltaic power is directly dependent on the photovoltaic current intensity, the electric power varies along with the voltage. All these have great influence upon the battery – the main component responsible for the operation of the cooling hybrid system

ESTIMATION OF TOTAL SOLAR RADIATION INCIDENT ON AN INCLINED SURFACE OF A SOUTH-FACING GREENHOUSE ROOF
Solar radiation is the driving force for the surface energy balance in buildings such as greenhouses. Greenhouses are generally tilted towards the sun in order to maximize the solar irradiance on the surfaces. Precise co...
POWER OUTPUT LOSSES IN SOLAR CELLS WHEN CHARACTERISED BY OPTIMAL RESISTIVE LOAD METHOD
The current and voltage of a solar cell can be measured by optimal load method. However, this method does not automatically adjust the load to ensure maximum power output as solar irradiance varies, hence power outpu...
