Wind, Cooling factor of PV system compared with tilted angle and longevity enhancement of Modules life
I come along many systems and said 100 x times already a cooling path inside PV Park should be determined
The breeze onsite can lower temperatures up to 10 degrees which is equivalent of 0,7 towards 1 % loss in degradation – an enormous potential
Although progress is being made on increasing solar PV efficiency and maximizing power produced, challenges
remain in decreasing PV panel operating temperatures. This study experimentally demonstrates the achievable
enhancements in solar PV efficiency if PV arrays are designed to take advantage of convective cooling. A 30–45%
increase in convective heat transfer coefficient was observed when the incoming flow direction shifts 180° to face
the rear surface of the PV panels. This increase corresponds to a 5–9 °C decrease in PV module temperature.
While changing the inclination angle of solar panels to optimize for convective cooling may be impractical or
undesirable, this parametric study highlights the signifcant impact wakes, turbulence and sub-panel velocity
have on panel operating conditions, through altering the convective heat transfer
