Tracking the Sun: The Installed Cost of Photovoltaics in the U.S. from 1998-2007

Description: As installations of grid-connected solar photovoltaic (PV) systems have grown, so too has the desire to track the installed cost of these systems over time, by system characteristics, by system location, and by component. This report helps to fill this need by summarizing trends in the installed cost of grid-connected PV systems in the United States from 1998 through 2007. The report is based on an analysis of installed cost data from nearly 37,000 residential and non-residential PV systems, to… more

Dye Sensitized Tandem Photovoltaic Cells

Description: This work provided a new way to look at photoelectrochemical cells and their performance. Although thought of as low efficiency, a the internal efficiency of a 9% global efficiency dye sensitized solar cell is approximately equal to an 18% efficient silicon cell when each is compared to their useful spectral range. Other work undertaken with this contract also reported the first growth oriented titania and perovskite columns on a transparent conducting oxide. Other work has shown than significa… more

Procedures for Determining the Performance of Stand-Alone Photovoltaic Systems

Description: This document provides the procedures for determining the performance of stand-alone PV systems. The procedures in this document provide a common approach for evaluating whether a given PV system is suitable to perform the function for which it was designed and manufactured to accomplish, and whether it will provide adequate power to run the load. These procedures cover small stand-alone PV systems. They cover complete outdoor system testing. Test results are valid only for the system that is t… more

Technical evaluation of a dual-junction same-band-gap amorphous silicon photovoltaic system at NREL

Description: On December 7, 1992, a 1.8-kW{sub ac} utility-interconnect photovoltaic (PV) system using amorphous silicon modules was brought on-line at the National Renewable Energy Laboratory`s photovoltaic test site. This system was deployed to conduct an in-situ technical evaluation of the PV array (in a high voltage configuration) and system performance and reliability in a utility-interconnect application. The system is unique due to the installation of construction-grade insulation on the back of each… more

Photovoltaic module performance and durability following long-term field exposure

Description: Our investigations of both new and field-aged photovoltaic modules have indicated that, in general, today's commercially available modules area highly reliable product. However, by using new test procedures, subtle failure mechanisms have also been identified that must be addressed in order to achieve 30-year module lifetimes. This paper summarizes diagnostic test procedures, results, and implications of in-depth investigations of the performance and durability characteristics of commercial mod… more

Analyses of Grounded and Ungrounded Photovoltaic Power Systems

Description: Photovoltaic (PV) modules and photovoltaic balance of systems equipment are designed, manufactured, and marketed internationally. Each country or group Of countries has a set of electrical safety codes, either in place or evolving, that guide and regulate the design and installation of PV power systems. A basic difference in these codes is that some require hard (low-resistance) grounding (the United States and Canada) and others opt for an essentially ungrounded system (Europe and Japan). The … more

Design goals and challenges for a photovoltaic-powered electrochromic window covering

Description: An estimated 1.0%-1.5% of the total cooling energy need in U.S. buildings, and 10%-30% of the peak electric utility power demand, is caused by unwanted solar heat-gain through windows. A large fraction of the approximately two billion square meters of building windows in the United States could benefit from the use of some solar gain control strategy. If a cost-effective, retrofit, electrochromic (EC) window covering were available, this energy savings potential could be realized in a relativel… more

Crystalline-silicon photovoltaics: Necessary and sufficient

Description: Photovoltaic (PV) energy systems have always been dominated by crystalline-silicon (c-Si) technology, and recent developments persuasively suggest that c-Si will continue to be the dominant technology well into the next century. The authors explain why c-Si technology is fairing much better than previously expected, and discuss the impact of improvements currently under development. They use a ground-up, engineering-based approach to predict the expected evolution of this type of PV system, and… more
