Since 2007 SolFocus has installed close to 2 MW of concentrated photovoltaic (CPV) power plants at multiple sites around the world. These installations have proved essential for assessing the value and variability of energy generation and performance ratio, as well as how accurately SolFocus is able to model and predict the product performance of its sites. This paper shares the data and results of...
The objective is to address both technical and financial aspects of a residential solar system. The impact of these two factors on financial paybacks of a resident is presented. This paper is divided to two sections. First, the impact of the technical factors such as geographical location of the solar system, proper panel installation, panel material, and system efficiency on the output electric power...
We optimize the sizing of the ratio inverter nominal power/PV array peak power for 4 technologies of PV modules under various meteorological conditions and in optimal conditions because the inverter always integrates a MPPT in the case of a grid connected PV system. The influence of various parameters is studied as the PV module technology, the PV module inclination and at last the location of the...
The aim of this article is to describe how closely PV grid-connected inverters operate at the actual maximum power point. To carry this study out six 50 Hz single-phase inverters were selected from European market, around of 5 kW. Each one of them was put into an outdoor grid-connected system installed in Legane??s (Madrid), Spain. Different electrical signals with respect to irradiance, PV module...
The paper describes the performance of the grid-connected 1-kW PV system installed on a grammar school in Poland after eight years of operation. It was designed and installed in year 2000 and from year 2001 it is fully monitored according to guidelines of standard IEC 61724. System was build from 20 a-Si modules (Millennia MST 50 MV by BP Solar) and Sunny Boy inverter. Monitoring system consists of...
