The high solar cell temperature, which varies according to the panel''s material and technology, diminishes the panel''s efficiency and causes irreparable damage to the cell materials [7]. Since most energy systems are temperature-dependent performance [8], excess heat must be removed from the PV panels to avoid these adverse consequences.
