“…From various studies, the dust accumulated on the PV module surface is found to decrease the transmittance of incident light and ultimately decrease the solar energy received by the solar cells in PV modules. In a study conducted in Baghdad Saidan et al (2015), the experimental results show that dust considerably reduces the maximum current from 6.9 to 16.4% depending on the time period of PV panels' exposure in dust-affected environment, i.e. from one day to one month.…”

Renewable energy sources are fast emerging as more reliable supplement of conventional energy sources. Among the various renewable sources, solar energy is most sought after in today's world. Solar PV modules when installed in outdoor environments suffer from various factors which are generally unaccounted in laboratory testing. Energy generation from solar collectors is primarily dependent on the amount of incident radiation on their surfaces. Soiling on modules is known to reduce the transmittance of incident rays to solar cell and cause significant output power degradation. Soiling is closely associated with the various factors such as module tilt angle, site-specific climate, outdoor exposure period, humidity, wind speed, dust characteristics and material properties. This experimental work is aimed to study the transmittance losses encountered by solar PV modules and the corresponding power degradation. The experimental results show an alarming reduction in transmittance as high as 69.06% over the dry study period experiencing no rain. The power of dusty solar module decreases by 29.76% compared to the module cleaned on daily basis. Dust deposition density on the PV module accounted to 9.6711 g/m 2 over the study period.

“…Another study conducted on 204 sites in California found that efficiency degradations during normal weather with no rainfall were 0.2% daily and 1.5-6.2% annually [83]. Moreover, an investigation of three dusty PV modules located in Baghdad, Iraq found that the average monthly, weekly, and daily percentage of performance degradation was 18.74, 11.8 and 6.24 respectively [84]. A five-month analysis in the Canary Islands, Morocco found a −20% reduction in PV efficiency due to soiling on the PV array from building construction [85].…”

“…Libya has the highest dust deposits from the Sahara Desert [82,83]. The performance of the PV module is negatively affected by environmental factors, especially soiling (which causes a 2-50% power loss), due to the scattering effects of the sun on its irradiance [83,84] and blocked sunlight. The PV cells were shaded by the two types of soiling, namely, soft shading due to air pollution, and hard shading due to dust blocks and bird droppings (typically 10 um) [83].…”

This paper elaborates a comprehensive overview of a photovoltaic (PV) system model, and compares the attributes of various conventional and improved incremental conductance algorithms, perturbation and observation techniques, and other maximum power point tracking (MPPT) algorithms in normal and partial shading conditions. Performance evaluation techniques are discussed on the basis of the dynamic parameters of the PV system. Following a discussion of the MPPT algorithms in each category, a table is drawn to summarize their key specifications. In the performance evaluation section, the appropriate PV module technologies, atmospheric effects on PV panels, design complexity, and number of sensors and internal parameters of the PV system are outlined. In the last phase, a comparative table presents performance-evaluating parameters of MPPT design criterion. This paper is organized in such a way that future researchers and engineers can select an appropriate MPPT scheme without complication.

“…Solar cells that cannot survive in extreme environmental conditions will have an impact on increased maintenance costs that will increase the electricity price. There are several environmental factors that affect the performance of solar cells such as dust [6], humidity [7] and temperature [8]. However, the temperature is the most important factor because in terrestrial application, solar cells are generally exposed to temperature ranging from 15 °C to 50 °C.…”

In many experiments, it has been reported that the performance of solar cells decreases with increasing temperature. This effect arises due to an increase in the intrinsic carrier concentration of material that directly affects the reverse saturation currents (J 0 ). As a result, the open circuit voltage which is inversely proportional to J 0 will decrease quite rapidly with increasing temperature. The intrinsic carrier concentration is determined by the bandgap energy of a material and its temperature. The Varshni relationship is a relation for the variation of the bandgap energy with temperature in semiconductors that has been used extensively in the model of a solar cell performance. But the problem is the Varshni relation just calculates the contribution of the vibrational part at the temperature, which is much greater than the Debye temperature. These works proposed a model of temperature dependence of solar cell performance that involves phonon energy correction and electron-phonon coupling interaction. This correction is applied because the electron-phonon coupling interaction is an intrinsic interaction of semiconductors. The existence of interaction cannot be avoided either experimentally or theoretically. The proposed model is compared with experimental data, which have fairly high accuracy.
