In the domestic/commerical, the simplest solution to this is to add more solar to compensate for the drop in efficiency. The next cheapest approach would be to cool the panels by heating water for domestic/industrial use, although the economics aren't as straightforward (depends on the cost of hearting fuel being displaced).

- danans 2y agoI agree that today it doesn't make cost sense, especially in a retrofit scenario and when the marginal cost of additional solar panels is so low. However, heat removal methods could make sense for much more efficient, but much more temperature-sensitive solar PV materials like perovskites.
