A Chilean research team has developed a residential-scale system to produce green hydrogen using discarded photovoltaic modules, combining them with a proton exchange membrane electrolyzer to reduce system complexity. The system achieves an annual energy yield equal to 88% of power electronics-based optimization, with daily hydrogen production exceeding basic household demand. With a levelized cost of hydrogen of approximately $5.8/kg, representing an 18% reduction compared to more complex systems, this low-cost solution could help address the growing volume of photovoltaic waste and the high cost of green hydrogen.
