2. Data Base of Temperature at Madinah Site
Madinah site (Latitude ¼ 24.46N and Longitude ¼ 39.62E) is
classified as semi-arid area and has a great potential of solar radiation
[14], with a daily annual average yield ranges from
4.5 KWh/m2
/day until 8.5 KWh/m2
/day, received on tilt PV surface.
The data have been recorded in our laboratory at Physics Department
since 2008 until June 2015. From the observed data, we note
that the ambient temperature at Madinah site is between 40 C
and 50 C during the summer months as indicated in the Fig. 1.
Sometimes, the ambient temperature is over 50 C as shown in
Fig. 2(aec) corresponding to the year 2011, 2013 and 2014
respectively. So, this will increase the solar cells temperature and
affect the performance of PV panels. For this, we propose the
hybrid system solar cell/thermoelectric module which is a solution
to improve the performance of solar cells in hot locations like
Madinah site.
