ABSTRACT
Growing interest in renewable energy worldwide have contribut
ed to the development and
the proliferation of solar systems. Many applications are built on solar energy because
of the great availability and sustainability of solar radiation. A particular interest is
geared toward photovoltaic water pum
ping system (PWPS) which happens to be very reliable
for the supply of drinking water to off
-
grid areas. However, the sizing of photovoltaic water
pumping system has been a great challenge involving intensive mathematical calculations
and also long colle
ction of data on solar radiation and weather parameters such as
temperature, humidity and others. Notwithstanding, an accurate sizing of the PWPS is very
important in the sense that an oversizing can result in heavy financial burden while an under
-
sizing
may not satisfy the targeted population in terms of water need. In view of this, many
research works have investigated a reliable and accurate method of measurement. The
current paper covers the development of an application tool, using Visual Delphi
, based on
a mathematical model of sizing photovoltaic water pumping. A database made of
different solar panel with their various characteristics as well as data collected from the
Retscreen software on weather in West Africa were adopted by
the software to ease the
dimensioning task. The software was built and tested against existing data to prove its
reliability.
