The electrical efficiency of photovoltaic panels
decreases as the temperature of PV cells increases as a result of
converting most of the absorbed solar energy to heat, which
needs to be dissipated effectively and economically. In this study,
a sheet of 0.25 mm silicon isolator type Sil-Pad 400 supplied by
Henkel Electronics materials company with thermal conductivity
of 0.9 W/m.K was laminated at the back of solar cells instead of
tedlar layer to enhance the thermal conductivity of PV panel
back layers. The constructed silicon isolator PV panel is outdoor
tested at the same time with another standard PV panel having
the same parameters under the same conditions and in the same
position and location. The experimental results showed an
improvement in electric power generation and cells temperature
for the constructed silicon isolator panel. The front surface
temperature of the silicon isolator panel was lower than that of
standard panel by 8 °C to 1.5 °C, where the back surface
temperature of the silicon isolator panel was 6 °C to 1 °C lower
than that of standard panel. The overall average increase in
power generation for silicon isolator panel was about 13% with
respect to the standard panel.
