Abstract. PV modules are the most reliable component of a photovoltaic (PV) system. This supposed reliability leads the modules to have a warranty of up to 25 years. With the increasing insertion of PV in the energetic matrix, it is necessary to evaluate and guarantee the reliability of this source. This paper presents an evaluation of degradation in PV modules installed 15 years ago on the roof of the Department of Electrical Engineering, Federal University of Ceará, Brazil. This evaluation uses two methods: visual inspection and analysis to measure degradation degree in electrical properties of the modules. Maximum power (P MPP ); Current at the maximum power point (I MPP ); Voltage at the maximum power point (V MPP ); Short circuit current (I SC ) and Open circuit voltage (V OC ) are measured using a power curve tracer and compared with manufacturers data. Visual analysis show that delamination and discoloration are the degradations found in most of the modules. Considering the electrical parameters, a MPP reduction of 30% was found.

“…It is obvious that the PV output power decreases from 20.6 to 15.4 kW when the PV cell temperature increases from 25. temperature increases from 0 to 40 °C. Currently, there is interest to increase the efficiency of PV by reducing the cell temperature using different cooling methods [59][60][61][62][63]. Figure 18.…”

The There are many factors influencing the performance of photovoltaic (PV) systems. Among these factors, temperature and solar radiation are two major parameters that have a large effect on the efficiency of PV systems. The cell temperature of PV panels is related to the ambient temperature while the solar radiation incident on the surface of the PV modules depends on the slope and azimuth of these modules. Furthermore, ground reflectance (albedo) affects the irradiance incident on the PV panel surface, which in turn affects the output of a PV system. Nevertheless, the effects of these factors on the economic performance of the solar PV systems are scarcely reported. This paper presents a complete design of a stand-alone PV/battery system to supply electric power for a mobile base station in Choman, Erbil, Iraq. The effects of different factors on the total electricity produced by PV arrays and its economic performance are simultaneously investigated. HOMER software has been used as a tool for the techno-economic and environmental analysis. As indicated from the simulation results, the PV array capacity and its economic performance are highly affected by the variation of the slope and azimuth. With a base case (albedo of 20% and average annual ambient temperature of 11°C), the best feasible system which is achieved by facing PV due to south with a tilt angle of 40° or 45°, is found to have net present cost (NPC) of 70595 $ and cost of energy (COE) of 0.54 $/kWh. Moreover, the results indicate that increasing the ground reflectance from 10% to 90% results in a 7.2% decrease in the PV array capacity and about 3% decrease in the NPC and COE. On the other hand, increasing the ambient temperature from 0°C to 40°C results in a 19.7% increase in the PV array capacity and an 8.2% increase in the NPC and COE. Furthermore, according to the ambient temperature of Choman, using PV modules with high sensitivity to temperature is found to be an attractive option. Provided simulation performance analysis proves that the studied parameters must be treated well to establish an enabling environment for solar energy development in Iraq.
