We propose a novel methodology to select candidate locations for solar power plants that take into account solar variability and geographical smoothing effects. This methodology includes the development of maps created by a clustering technique that determines regions of coherent solar quality attributes as defined by a feature which considers both solar clearness and solar variability. An effi...

The future construction of utility-scale solar power plants in Australia will present challenges to integrate these plants into the existing electricity industry. This paper considers the likely solar forecasting requirements to facilitate the integration of photovoltaic and concentrating solar thermal plants into the Australian National Electricity Market (NEM). Many market participants may be...

Economic evaluation of 12 MW grid-connected wind farms and PV power plants in two regions in Northern Cyprus for electricity generation was investigated. The wind speed, sunshine duration, and solar global radiation characteristics were analyzed using monthly data collected over 17 years (2000-2016) for Girne and nine years (2008-2016) for Lefkoşa, which were measured at various heights. The re...

in the sector of electricity production, the existence of investment resources limitation and environmental factors are the main factors that influence this process. the reduction of costs and the destructive impacts of environmental have been always mentioned by specialists. consequently, the drasticality of the environmental protection and the electric-energy production lead to focus on solar...

Traditional instrumentation based on discrete and wired solutions, presents many difficulties to measure or to compute plant physiological responses due to the large geographical areas that may be involved. This paper describes an implementation of a wireless sensor network for agriculture low data-rate applications. This network includes several solar powered wireless acquisition stations used...

Quantifying spatial and temporal variations in optimal tilt angle of a solar collector relative to a horizontal position assists in maximizing its performance for energy collection depending on changes in time and space. In this study, optimal tilt angles were quantified for solar collectors based on the monthly global and diffuse solar radiation on a horizontal surface across Turkey. The datas...

How tropical trees flower synchronously near the equator in the absence of significant day length variation or other meteorological cues has long been a puzzle. The rubber tree (Hevea brasiliensis) is used as a model to investigate this phenomenon. The annual cycle of solar radiation intensity is shown to correspond closely with the flowering of the rubber tree planted near the equator and in t...

Needle dimensions, needle surface area, needle dry weight per area (LWA) and needle density (ND, needle weight per volume) were measured in terminal current-year shoots in a natural canopy of variably sized Picea abies (L.) Karst. trees growing along a light gradient. Needle shape was described as a rhomboid. Needle width (D(2)) increased with increasing diffuse site factor, a(d) (relative amou...

We analyze the efficient subsidy for durable good technologies. We theoretically demonstrate that a policymaker faces a tension between intertemporally price discriminating by designing a subsidy that increases over time and taking advantage of future technological progress by designing a subsidy that decreases over time. Using new empirical estimates of household preferences for residential so...
