| Transition from dependency on the main source of electricity generation (fossil fuel) to the most promising renewable energy source (solar energy) in Malaysia is driven mainly by environmental and economic factors. However, to ensure the success of this process, solar PV technology in the country has to be reliable and efficient enough. There are many alterable and unalterable factors that can govern a PV module's efficiency. Dust, humidity and air velocity are some of the location-dependent environmental factors that fall under the unalterable factors group. Each of these three factors can degrade the efficiency of a PV panel by causing, e.g., incoming solar radiation attenuation, changes in electrical characteristics, physical damages, temperature rise, etc. One factor can also affect the other factor, hence indirectly impact the panel performance. In more severe cases, undesired total module failure has been recorded upon extreme exposure. On the other hand, wind speed can enhance PV panel performance by promoting heat transfer. This work reviews, elaborates and summarizes the effects of dust, humidity and air velocity on solar PV cell efficiency. |
