Two-layer phase change materials for solar module cooling

Researchers in Iran have tested four different two-layer PCMs across several cooling system configurations and have found that the payback time of the proposed cooling tech is still far from reaching commercial viability. The system, however, was able to improve PV power generation by more than 3% and produce hot water with a temperature of up to 48 Celsius degrees from the solar module's excess heat.A group of scientists in Iran has considered using a two-layer phase change material (PCM) as a passive cooling agent for a cooling system for photovoltaic panels. PCMs are able to absorb, store ...
