... The efficiency PV module system depends on air temperature and thus solar panel temperature is usually between 15°C to 35 °C. When at the lower temperatures, the power of the PV module system increase, while at the higher temperature it will lose efficiency per degree over 25°C , . ...
The objective of this research is to identify the temperature effect on the solar photovoltaic (PV) power generation and explore the ways to minimize the temperature effect. The photovoltaic (PV) cells suffer efficiency drop as their operating temperature increases especially under high insolation levels and cooling is beneficial.
Solar panels are power tested at 25 0 C, so the temperature coefficient percentage illustrates the change in efficiency as it goes up or down by a degree. For example if the temperature coefficient of a particular type of panel is -0.5%, then for every 1 0 C rise, the panels maximum power will reduce by 0.5%.
After observing the above system it has been identified that, when the PV modules temperature decreases the overall efficiency of the PV panel output power increases. From the gathered data, a suitable photovoltaic thermal system (automated active cooling) is designed with Arduino UNO board for solar panels.
Although extreme conditions will affect solar panel performance efficiency, solar panels are rated to operate in a very wide temperature range. Designed to reflect real-world conditions, most solar panels have an operating temperature range wide enough to cover every single day of your system’s multi-decade lifetime.
This paper presents a review of the forecasting methods to predict solar irradiance and ambient temperature, considering the sensitivity to the forecasting horizon. The methodology includes estimating an interval for ambient temperature and solar irradiance by using the Mean Absolute Error as the percentage of variation in these parameters.
