Today, solar energy conversion technologies, which are among the methods of obtaining renewable, sustainable, and clean energy, show rapid development. One of the most common technologies is Photovoltaic Solar Power Plant (PVPP), which provides electricity by direct conversion of the energy carried by the sunlight (or daylight). These power plants are socially accepted in environmentally-friendly and economical energy production. However, there are some debates about the environmental impacts of these power plants. One of the issues at the focus of these debates is whether dark-colored photovoltaic solar module (panel) arrays in large numbers used to build these power plants alter the natural ground reflectivity (albedo) of the land where they are installed. For this reason, they may also affect the local air temperature cycles of the region where they are located. This environmental problem, referred to as the Photovoltaic Heat Island Effect (PVHIE) in the literature, arises from the optical and thermal properties of photovoltaic modules interacting with their close environment. A three-year field project and study was carried out to observe this effect in a PVPP constructed in the Sekbandemirli rural area in the Tavşanlı district of the Kütahya province in Turkey. The relevant weather data collected by the meteorological stations installed on specific locations inside and outside Sekbandemirli PVPP were analyzed using statistical (ANOVA and Tukey’s HSD), correlational (Pearson and Spearman), graphical (percentage column distribution, daily and monthly line charts, and representative illustrations) and simulation-based (the microclimate simulation software ENVI-met) methods. Accordingly, the heat island formations, which can be expressed as "transient", whose frequency of occurrence changes daily and seasonally, have been found at the Sekbandemirli PVPP field center. The air temperatures recorded at the field center show the differences between “(-3) – 6°C” compared to those recorded at the reference location outside the field. The higher daytime ambient air temperatures up to 6°C difference at the field center significantly indicate the evident (and positive) PVHI formations, although a less effective (up to -3°C) cooling effect (negative PVHIE) prevails mostly at nighttimes. This thesis is the first study on PVHIE in Turkey and the world, in line with the methods used within its content.

These plants are qualified as one of the pioneering applications among clean energy production methods. However, as the modules cover large areas and as they are produced by mostl...
Study Case of Solar Thermal and Photovoltaic Heat Pump System for Different Cities in Turkey
Moia-Pol, Andreu; Pujol-Nadal, Ramon; Martinez-Moll, Victor; Bonyadi, Nima; Baker, Derek (2016-10-14)
The combination of solar thermal, photovoltaic, and heat pump technologies is a welcome advancement in countries with large solar resources such as Turkey. These systems could have similar efficiencies throughout the year for different locations in Turkey if we adjust the solar storage according to the weather conditions. In this paper, solar heating with a heat pump system for buildings have been designed to achieve different values of the fraction of primary energy saved using Flat Plate Collectors (FPC) ...
