  • This chapter reviews some of the basic magnitudes of solar radiation and some of the basics of PSpice. A brief description of a photovoltaic system is followed by definitions of spectral irradiance, irradiance and solar radiation. Basic commands and syntax of the sentences most commonly used in this book are shortly summarized and used to write PSpice files for the AM1 SG and AM0 sun spectra, which are used to plot the values of the spectral irradiance as a function of the wavelength and compare them with a black body radiation.

  • The goal of the first edition of this textbook was to present a comprehensive engineering basis for photovoltaic (PV) system design, so the engineer would understand the what, the why and the how associated with electrical, mechanical, economic and aesthetic aspects of PV system design. The first edition was intended to educate the engineer in the design of PV systems so that when engineering judgment was needed, the engineer would be able to make intelligent decisions based upon a clear understanding of the parameters involved.

  • Solar electric plants shall be understood to be photovoltaic energy converters that are able to self-sufficiently satisfy a mean energy demand over a significant period of time, be it an appliance that is permanently hooked up or just for sporadic power supply of appliances. Such plants have in common that their input and output quantities fluctuate widely. They can therefore only be dimensioned on the basis of a mean value and are not able to satisfy this demand without the possibility to store energy. ...

  • Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...
