Abstract :
Accurate monitoring and measurement of
solar photovoltaic panel parameters are important for
solar power plant analysis to evaluate the performance
and predict the future energy generation. There are
always challenges of getting such data due to huge
amount of money to be spent on state of the art
equipment or the purchase of reliable satellite weather
data. This study aimed at the development of a cost-
effective parameter-measuring and logging system for
solar photovoltaic system. A PIC Microcontroller,
Liquid Crystal Display, 10W Solar Panel, Real-time
Clock, and analog processing circuit are the essential
parts of the developed solar data logger. The system
measures various parameters, including voltage, current,
light intensity, together with date and time. Current
sensor and voltage sensor were integrated on data logger
board to measure parameter that affected efficiency of
PV system. The accuracy of the developed system was
determined by comparing the measured parameters with
that of conventional standard measuring instruments
which shows good agreement. One of the benefits of the
data logger is the ability to automatically collect and
store data over a long period of time. The data can be
plotted into V-I graph and P-V graph for analysis. The
developed data logger can be used as portable recorder
to compare the solar power in different area at specific
time and seasons.
