Outdoor PV Module Degradation of Current-Voltage Parameters: Preprint

Description: Photovoltaic (PV) module degradation rate analysis quantifies the loss of PV power output over time and is useful for estimating the impact of degradation on the cost of energy. An understanding of the degradation of all current-voltage (I-V) parameters helps to determine the cause of the degradation and also gives useful information for the design of the system. This study reports on data collected from 12 distinct mono- and poly-crystalline modules deployed at the National Renewable Energy La… more

Southeast Regional Clean Energy Policy Analysis (Revised)

Description: More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports. Many of the region's aging coal power facilities are planned for retirement within the next 20 years. However, estimates indicate that a 20% increase in capacity is needed over that time to meet the rapidly growing demand. The most common incentives for energy efficiency in the Southeast are loans and rebates; howeve… more

Final Report for PV Incubator Subcontract No. NEU-0-99010-09: March 29, 2010 - March 28, 2011

Description: MicroLink has developed a process technology that will enable the manufacture of high-efficiency, low-cost, multijunction solar cells for use in concentrating photovoltaic (CPV) applications. The multijunction cells were fabricated using a novel low-temperature wafer bonding process. A triple-junction InGaP/GaAs/Ge tandem solar cell with efficiency of 30% at 1 sun AM1.5 illumination was fabricated by wafer bonding a dual-junction InGaP/GaAs cell to a single-junction Ge cell. Temperature cycling… more

Photovoltaic Degradation Risk: Preprint

Description: The ability to accurately predict power delivery over the course of time is of vital importance to the growth of the photovoltaic (PV) industry. Important cost drivers include the efficiency with which sunlight is converted into power, how this relationship changes over time, and the uncertainty in this prediction. An accurate quantification of power decline over time, also known as degradation rate, is essential to all stakeholders - utility companies, integrators, investors, and researchers a… more

Measurement and Modeling of Solar and PV Output Variability: Preprint

Description: This paper seeks to understand what temporal and spatial scales of variability in global horizontal radiation are important to a PV plants and what measurements are needed to be able to characterize them. As solar radiation measuring instruments are point receivers it is important to understand how those measurements translate to energy received over a larger spatial extent. Also of importance is the temporal natural of variability over large spatial areas. In this research we use high temporal… more
