Investigation of the performance of photovoltaics installed close to river
The effect of temperature and relative humidity on photovoltaics close to river in calabar was studied. A KT-908 precision digital hygrometer and thermometer, and a M890C+ digital multimeter were used in the process. Results obtained shows that the effect of relative humidity on current, power and efficiency are the same. The results also show that voltage remains fairly stable between 65% to 75% relative humidity. While efficiency increases with temperature up to the maximum operating temperature of the photovoltaic module before starting to decrease. Peak in efficiency was observed at a relative humidity value of 65% and module temperature of about 470C at noon.
