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....
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.
Photovoltaics have started replacing fossil fuels as major energy generation roadmaps, targeting higher efficiencies and/or lower costs are aggressively pursued to bring PV to cost parity with grid electricity. Third generation PV technologies may overcome the fundamental limitations of photon to electron conversion in single-junction devices and, thus, improve both their efficiency and cost. This book presents notable advances in these technologies, namely organic cells and nanostructures, dye-sensitized cells and multijunction III/V cells. ...
Congratulations! You are reading a book about a technology that has changed the way we think
about energy. Photovoltaics (or PV) is an empowering technology that has shown that it can
generate electricity for the human race for a wide range of applications, scales, climates, and
Over the last decade, PV technology has shown the potential to become a major source of
power generation for the world – with robust and continuous growth even during times of
financial and economic crisis. That growth is expected to continue in the years ahead as
worldwide awareness of the advantages of PV increases. At the end of 2009, the world’s PV
cumulative installed capacity was approaching 23 GW. One year later it was 40 GW. In 2011,
more than 69 GW are installed globally and...
