“…The advantages of using solar energy systems fall into two main categories: ecology and socioeconomic issues. From an ecological aspect, the use of solar energy technologies has various positive impacts that include reduction of greenhouse gas emissions (like CO 2 , NO x ) and of toxic gas emissions (SO 2 , particulates), prevention of soil pollution, reduction of transmission cost, and improvement in the quality of water resources [3][4][5][6][7][8]. The advantages of solar technologies comprise energy independency, employment opportunity creation [4,5], acceleration of electrification of rural communities in isolated areas, and diversification and security (stability) of energy supply [4,5,9].…”

This paper presents modelling electrical performance of a typical PV panel/module (which is Kyocera 200GT) for constant electric loads (which are 2Ω, 4Ω, 6Ω, and 8Ω) under weather condition of a tropical region. The specific case of the city Jigjiga (9.35°N,42.8°E), located in the Eastern region of Ethiopia is considered. Electrical characteristics of the PV module are determined on the basis of detailed numerical algorithm, which was designed based on tested numerical technique from reviewed articles. The overall evaluation of the hourly variation in the electrical performance of the PV module is done by means of graphical technique, which determines the operating point of the PV module on voltage vs. current plane for each load, and the performance of the PV panel is compared for each load. The 4Ω electric load resulted in highest daily energy output of the PV panel on a daily basis for 11 days of the month of January (out of 12 considered days), but in the last day it resulted in a poorer performance with respect to the other two electrical loads (i.e., 6Ω and 8Ω electric loads).

Photovoltaic (PV) systems sometimes called solar cells have found widespread application because they are simple, are compact, and have high power-to-weight ratio [8].…”

Recent studies on photo voltaic system (PVs) have concentrated on minimize the costs and maximize the conversion effectiveness. In order to maximize the effectiveness of PV energy conversion systems, solar panels should be operated at maximum power points (MPP). At MPP, solar arrays generate the electric energy at maximum efficiency and minimum losses. Solar cells have variable current and voltage characteristics and MPP depends on solar irradiations and ambient temperature. So a maximum power tracking control should be made rapidly in different temperature and solar radiation conditions. In this study; solar cell was obtained by using equivalent circuit of solar cell with Matlab / Simulink connected with dc-dc converter to fed brushless dc motor BLDC and water pumping system, this paper drive using adaptive neuro-fuzzy inference system (ANFIS) technique. The proposed (ANFIS) controller is trained off-line to identify the optimum output power of P-V system and desired water flow rate. This paper describes the operation of the system and the development of component models for the array, using ANFIS technique to enhance performance of system and to get the maximum power from P-V under different conditions of the solar insolation and temperature to get maximum flow rate of water to water pumping system WPS. An iteration technique which is mathematicalbased is also presented for comparison and evaluation purposes. The paper indicates accuracy, robustness and effectiveness of the proposed models in water flow rate control, economic feasibility and fault detection.

“…These benefits fall into two main categories: environmental and socio-economic issues. From an environmental point of view, the use of solar energy technologies has several positive implications that include: reduction of the emission of greenhouse gases (mainly CO2, NOx) and of toxic gas emissions (SO2, particulates), recovery of degraded land, reduced requirement for transmission lines within the electricity grid and improvement in the quality of water resources [1][2][3][5][6][7]. The socio-economic benefits of solar technologies include: increased regional and national energy independence, creation of employment opportunities [4,5], and acceleration of electrification of rural communities in isolated areas and diversification and security (stability) of energy supply [2][3][4].…”

In this paper thermodynamic modeling of organic Rankine cycle (ORC) driven by parabolic trough solar collectors is presented. Eight working fluids for the ORC were examined. The effect of turbine inlet temperature on main energetic and exergetic performance parameters were studied. The influences of turbine inlet temperature on turbine size parameter, turbine outlet volume flow rate and expansion ratio were also investigated. Important exergetic parameters including irreversibility ratio and total exergy destruction rate were also included in the analysis and evaluated. The study reveals that increasing the turbine inlet temperature results in increasing the net electric efficiency, net power output, exergy efficiency and expansion ratio while the total exergy destruction rate and turbine size parameter are reduced. From the considered working fluids, o-xylene gives the best energetic and exergetic performance. The results of the study also show that the main source of exergy destruction occurs in the solar collector where 74.9% of the total exergy loss is destructed. Next to collectors, 18.2% of the total destructed exergy occurs in the condenser.
