Most panels experience a drop in efficiency of 0. 5% for every degree Celsius above 25°C (77°F). Keeping panels cool boosts energy output, which is why ventilation behind panels and quality insulation within the building work hand in hand.

A panel behind glass can still produce electricity, especially near a sun-facing window with direct daylight. The problem is that window glass, coatings, reflections, indoor placement, and weaker angles all reduce how much usable solar energy actually reaches the cells.

For enclosures housing string inverters or DC disconnects with moderate heat loads (under 500W), passive cooling through calculated ventilation openings, heat sinks welded to the enclosure wall, and solar radiation shields can be sufficient.
