Talk Abstract

Concentrating Photovoltaic (CPV) systems can offer a host of advantages over conventional flat panel devices, the most notable being: a higher electrical conversion efficiency in the PV cells, better use of space, ease of recycling of constituent materials, and reduced use of toxic products involved in the PV cells’ production process. However, the viability of Building-Integrated Concentrating PV (BICPV) systems is dependent on their ability to offer a comparative economic advantage over flat panel photovoltaic technologies whose market prices are decreasing from day to day and which offer other advantages such as ease of replacement of structural elements. The CPV systems are categorized by type of concentration technology and concentration factor.

A complete BIPV system includes:
The PV modules (which might be thin-film or crystalline, transparent, semi-transparent, or opaque);A charge controller, to regulate the power into and out of the battery storage bank (in stand-alone systems);A power storage system, generally comprised of the utility grid in utility-interactive systems or, a number of batteries in stand-alone systems; Power conversion equipment including an inverter to convert the PV modules’ DC output to AC compatible with the utility grid; Backup power supplies such as diesel generators (optional-typically employed in stand-alone systems); and Appropriate support and mounting hardware, wiring, and safety disconnects.

BIPV are part of the PV industry, but due to their possible usage as building products, they are also seen as part of the green building movement. . In developed economies, the BIPV system is interfaced with the available utility grid; BIPV may also be used in standalone, off-grid systems, and are cost-effective. Commercial, industrial, and residential buildings are the biggest consumers of primary energy and their energy demands continue to increase. The only way to reverse this trend is to combine energy efficient building strategies with integrated renewable energy sources. Tata BP solar has executed the largest BIPV projects in India at Samudra Institute of Maritime Studies.
