ABSTRACT: A development of an acquisition of the characteristic of a solar panel by
automatic load variation system is put into play and coupled to an
instrumentation chain for taking account of temperature. A programmed digital
microprocessor control enables this automation. Design and implementation of a
device for automation of variations of the resistive load are powered by solar panel. It is provided by a PIC 16F877A running a
computer program that we have developed on the basis of an algorithm according
to the operation that we have set. By varying automatically the resistive load,
we were able to automatically acquire the characteristic I-V and temperature of
the solar panel. With automatic combinations of the 10 resistors, we have obtained 1024 measures of the characteristic
curve of the solar cell which has a good accuracy. The change in load and
temperature measurement allows us to have the characteristic curves parameterized
by temperature.
