In 2020, researchers tested a self-moistening hydrogel mat under solar panels; it cooled them by at least 10C and boosted output by up to 19%

New research introduces a cooling gel for solar panels. This gel absorbs moisture at night and releases it as vapor during the day. The cooling effect significantly boosts electricity output and panel longevity. This innovation promises to reduce solar electricity production costs. The technology offers a low-maintenance solution for hotter climates.
