    Output power loss of photovoltaic panel due to dust and temperature
    (International Journal of Renewable Energy Research, 2017) Tripathi, A.K.; Mangalpady, M.; Murthy, C.S.N.
    Due to increase in power consumption and greenhouse problem all over the world, an alternative source is necessary for generating clean and environmental friendly electric power. In this regard, solar energy could be a good choice of power generation, since the cost of solar panels decreasing rapidly in the past few years. Moreover, solar energy has also become more efficient as compared to other source of energy systems. The performance of solar photovoltaic (PV) panel depends on the incoming light to panel surface and it is governed by environmental parameters, mainly dust and temperature. Dust shading creates a barrier in the path of incoming sun light, which reduces the amount of sunlight falling on photovoltaic panel surface, and hence power output and performance of panel reduces significantly. The increase in temperature above maximum power point temperature results in power output loss of panel. This paper presents the phenomena of performance degradation of PV panel due to dust shading and temperature.

    Output power enhancement of solar PV panel using solar tracking system
    (Bentham Science Publishers B.V. P.O. Box 294 Bussum 1400 AG, 2019) Tripathi, A.K.; Mangalpady, M.; Murthy, C.S.N.
    Solar Photovoltaic (PV) energy conversion has gained much attention nowadays. The output power of PV panel depends on the condition under which the panel is working, such as solar radiation, ambient temperature, dust, wind speed and humidity. The amount of falling sunlight on the panel surface (i.e., solar radiation) directly affects its output power. In order to maximize the amount of falling sunlight on the panel surface, a solar tracking PV panel system is introduced. This paper describes the design, development and fabrication of the solar PV panel tracking system. The designed solar tracking system is able to track the position of the sun throughout the day, which allows more sunlight falling on the panel surface. The experimental results show that there was an enhancement of up to a 64.72% in the output power of the PV panel with reference to the fixed orientation PV panel. Further, this study also demonstrates that the full load torque of the tracking system would be much higher than the obtained torque, which is required to track the position of the sun. This propounds, that the proposed tracking system can also be used for a higher capacity PV power generation system. © 2019 Bentham Science Publishers.
