Abstract
Environmental parameters have great impact on photovoltaic systems. It is important to understand the effect of environmental factors on photovoltaic systems. Irradiance, ambient temperature, wind speed, humidity, clouds is important environmental parameters which have direct impact on photovoltaic systems. In this work ambient temperature and wind speed are analyzed and their activities with the performance of photovoltaic cell are understood. Wind speed and ambient temperature are related to each other and together they have effects on photovoltaic systems. In this work, it is viewed that when ambient temperature is increased then the power production of the PV cell decreases. About wind speed, when the wind speed is increased then the PV power production increased is observed in this work. In total effect when ambient temperature and wind speed changes at a time what happens to PV power is discussed. Significant result is observed that is, the time wind speed is high and ambient temperature is low the PV cell power is more and on the other hand in the time when there is no wind flow and 2 temperature is high then the power production from PV is low. For crystalline silicon cell the maximum power point decrease linearly with the increase of ambient temperature and maximum power point increasing with increase of wind speed.
Keywords: Photovoltaic system, ambient temperature, wind speed, maximum power point
