The accurate estimation of power production is fundamental to ensuring a solar system is operating correctly. It is also essential to assure the lenders and investors financing the project that the debt will be repaid and expected returns will be achieved, and to assure smooth integration of solar resources on to the grid. In the wind industry, for example, this has been accomplished through regression techniques applied to plots of power production as a function of wind speed. This methodology has not yet been widely used in the solar sector. This paper evaluates whether a linear regression methodology can be used to predict power output in solar, identifies key variables in this regression, and assesses the accuracy of the regression. Amonix CPV systems were used to test and validate the methodology. Copyright © (2011) by the American Solar Energy Society. Source

Lattice-mismatched-strain-driven, defect-free, 3-D islands, dubbed self-assembled quantum dots (SAQDs), currently provide the most advanced platform for quantum-dot-based devices with successful applications to SAQD lasers and considerable potential for infrared detectors. For the latter, one of the limitations is the short optical path length owing to the difficulties in creation of large numbers of quantum dot layers without formation of structural defects arising from accumulated strain. This limitation can be considerably overcome by creation of an appropriate resonant cavity to enhance the optical field in the SAQD regions. In this paper, we demonstrate resonantcavity- enhanced quantum dot infrared photodetectors in the midinfrared (MIR, 3-5 μm) regime. For effective enhancement, the SAQDs are designed to generate a very narrow peak (δλ/λ ̃10%) in the intraband photocurrent response in the MIR range utilizing short period superlattices as the quantum confining layers. Incorporating such SAQD layers at specific enhanced electric field regions within the resonant cavity comprising a two-pair GaAs/air-gap back mirror and a GaAs surface front mirror, we have obtained QDIP detectivity enhancement of ̃8-12 times. © 2010 IEEE.

Conference Record of the IEEE Photovoltaic Specialists Conference

In 2008 and 2009, Amonix installed 300 kW of its seventh-generation systems in Las Vegas, USA. Use of III-V multijunction cells resulted in a ∼30% reduction in the cost of energy of Amonix CPV solar power plants. AC system efficiencies currently reach 25% and energy yield is over 2500 kW-hr/kW. A performance model has been developed that predicts system output based on the spectral response of the III-V multijunction cell corrected for operating conditions. This model is used to inform ongoing system optimization. Systems installed in 2010 are expected to deliver over 10% more power and energy. © 2010 IEEE. Source

Progress in Photovoltaics: Research and Applications

Amonix concentrating photovoltaic (CPV) solar power plants currently demonstrate AC efficiency of over 25% in the field. A model has been developed that predicts system performance based on the spectral response of the III-V multijunction cell corrected for environmental and atmospheric conditions. Historical meteorological data is used to predict future performance at target locations. With the cleaning schedule as the only adjustable variable, energy production has been within 2% of prediction after 9 months of operation. The model is used to improve performance, which is expected to increase by 10% in 2010. These improvements, combined with cost reductions in the MegaModule® design, put the Amonix CPV systems on track to achieve a levelized cost of electricity below US $100/MW-hr by 2012. © 2010 John Wiley & Sons, Ltd.
