“…For example, Ibrahim [55] experimentally demonstrated that solar modules installed in the Egyptian desert that have been exposed to dust for a period of one year showed an energy reduction of about 35%. Kimber et al [61] investigated the effects of deposition on energy production for large grid-connected systems in the US and developed a modeling framework for predicting soiling losses. These authors found that for North American deserts, PV system efficiency declines by an average of 0.3% per day during periods without rain [61].…”

These authors found that for North American deserts, PV system efficiency declines by an average of 0.3% per day during periods without rain [61]. The National Renewable Energy Laboratory analyzed 24 PV systems throughout the US and calculated a typical derate factor (percentage decrease in power output) due to dust deposition of 0.95% [74].…”

Greenhouse gas emissions Land use and land cover change Photovoltaic Renewable energy a b s t r a c t Renewable energy is a promising alternative to fossil fuel-based energy, but its development can require a complex set of environmental tradeoffs. A recent increase in solar energy systems, especially large, centralized installations, underscores the urgency of understanding their environmental interactions. Synthesizing literature across numerous disciplines, we review direct and indirect environmental impacts -both beneficial and adverse -of utility-scale solar energy (USSE) development, including impacts on biodiversity, land-use and land-cover change, soils, water resources, and human health. Additionally, we review feedbacks between USSE infrastructure and land-atmosphere interactions and the potential for USSE systems to mitigate climate change. Several characteristics and development strategies of USSE systems have low environmental impacts relative to other energy systems, including other renewables. We show opportunities to increase USSE environmental co-benefits, the permitting and regulatory constraints and opportunities of USSE, and highlight future research directions to better understand the nexus between USSE and the environment. Increasing the environmental compatibility of USSE systems will maximize the efficacy of this key renewable energy source in mitigating climatic and global environmental change.

“…However, it should be noted that these factors must be addressed in determining the overall system energy production [15,16]. Development of a system energy rating procedure compatible with this power rating method is important future work, but is outside the scope of this paper.…”

This paper reviews the PVUSA power rating method [1][2][3][4][5][6] and presents two additional methods that seek to improve this method in terms of model precision and increased seasonal applicability.It presents the results of an evaluation of each method based upon regression analysis of over 12 MW of operating photovoltaic (PV) systems located in a wide variety of climates. These systems include a variety of PV technologies, mounting configurations, and array sizes to ensure the conclusions are applicable to a wide range of PV designs and technologies. The work presented in this paper will be submitted to ASTM for use in the development of a standard test method for certifying the power rating of PV projects. BACKGROUND AND PURPOSE

“…Additionally, we could not depend on there being a reduction of power from the panels as a method of determining when it should be cleaned since a whole cloudy day would also result in a reduction in absorption of solar rays. [1] The accumulation of dirt on solar panels ("soiling") can have a significant impact on the performance of PV systems in regions where rainfall is limited for a dry season of several months. This effect is magnified where rainfall is absent in the peak-solar summer months, such as in California and the Southwest region of the United States.…”
