Real Time Monitoring of Humidity and Temperature Effects on Pv Cells with Data Logger System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Today the world is focused in harnessing non-conventional sources of energy to cater the energy needs of the world’s growing population. Solar energy is one such renewable energy source with great potential to be the present and future energy source. Solar cells or PV cells are used to harness sun’s energy and change it into electricity. These solar cells work on the principle of photovoltaic, conversion of sunlight into electricity. Solar cells working is affected by various atmospheric factors like temperature, humidity, windspeed etc. This project uses a data logger chip embedded with the mobile phone to monitor the solar voltages continuously, the output of the pv panels can be saved and analyzed to determine optimum working conditions of the solar panel. The temperature factor affects the flow of electric current by the variation in the velocity of electrons flow. Humidity is also another governing factor that effect the working conditions of pv cell. Water vapour and air are at the same temperature in the atmosphere. The more the water vapour held in the air the temperature is affected. The warm air holds more water than cool air, thus affecting the efficiency of pv cells. Solar cells provide maximum efficiency ie optimum output power under certain atmospheric conditions like temperature and humidity and this is the designing aspect of pv cells.
