“…The spectral effects of accumulated dust layers have been previously reported [15,[28][29][30][31][32][33][34][35][36][37][38][39][40]. Specifically, the critical region is in the additional optical absorption in the solar spectrum range of ~300 nm to ~600 nm.…”

The choice of a particular PV technology for best performance is sometimes based upon a single factor or single operating condition. However, many parameters have functionalities that oppose each under actual operating conditions. In this paper, the comparisons of different PV module technologies under moderate environmental conditions (Tropical Climate Zone, Belo Horizonte, Brazil) are explored based upon the two competing parameters of soiling-layer spectral effects and panel operating temperature. Specifically, low-bandgap PV technologies (e.g., Si or Cu(In,Ga)(SSe)2) are reported to have performances less affected by the absorption of incoming sunlight than higher-bandgap absorbers (e.g., a-Si:H or CdTe). However, the opposite is true for operating temperatures, with higher bandgaps having advantages under higher-temperature operating conditions. We present a simple comparative soiling-temperature model with experimental collaborative data to address the following question: What is the controlling parameter of the combination of soiling spectral effects and temperature on lower- and higher-bandgap module technologies? Temperature coefficients are measured for groups of modules for the four technologies having bandgaps ranging from 1.1 to 1.7 eV. Additional optical absorption for the soiling layers in the range of 300 nm to ~600 nm is confirmed by transmission measurements. The data from our soiling monitoring stations indicate that these potential spectral effects are based on consistent differences in soiling ratios and soiling rates. Some differences between the model predications and experimental observations are discussed. This paper reports temperature and soiling regions of “best-of-class” performances for these four commercial PV technologies in this climate region based upon the two competing parameters.

“…5.1.3 Photovoltaic system. Photovoltaic (PV) systems originate from intermittent energy sources, the power generated depends largely on solar radiation (the solar rays that really affect the generation of electricity are ultraviolet and infrared rays, hence the importance of knowing the spectrum of sunlight of the ZNI), and of the temperature of the operation [71].…”

This degree project studies the island mode microgrids or isolated microgrids of the National Interconnected System (SIN, for its acronym in Spanish) as an alternative to supply the energy demand of users located in rural areas designated as Non-Interconnected Zones (ZNI), for its acronym in Spanish) of the department of Cauca in Colombia.The motivation for the project arises from understanding a social problem and wanting to find a solution through renewable energy resources that is reliable, economically viable and efficient for the environment.

“…Losses due to dirt η dirt provide an average 2% of reduction in energy production for the deposit of dust and other materials on the glass of the modules. Thus, a typical value η dirt = 0.98 is used in the present work [27,28]. Note that in case of horizontal modules, the cleaning made by rain is reduced, and in case of emission of pollution close to the plants from special industrial processes [29], losses can be more than 7%.…”

A basic battery management system (BMS) permits the safe charge/discharge of the batteries and the supply of loads. Batteries are protected to avoid fast degradation: the minimum and maximum state-of-charge (SOC) limits are not exceeded and fast charge/discharge cycles are not permitted. A more sophisticated BMS connected to a photovoltaic (PV) generator could also work with the double purpose of protecting storage and reducing peak demand. Peak reduction by storage generally requires the forecast of consumption and PV generation profiles to perform a provisional energy balance. To do it, it is required to have accurate information about production profiles, that is, to have at disposal accurate weather forecasts, which are not easily available. In the present work, an efficient BMS in grid-connected PV plants for residential users is described. Starting from raw 1-day ahead weather forecast and prediction of consumption, the proposed BMS preserves battery charge when it is expected high load and low PV production and performs peak shaving with a negligible reduction in self-sufficiency.
