Solar generator performance with load matching to water electrolysis

摘要: A 7 W generator, based on monocrystalline silicon solar cells, was directly wired to an electronic load, simulating the current-voltage characteristic of advanced water electrolyser. System performance monitored from January 15 July 7, 1980. Measurements included current and voltage at load point maximum power output, global irradiance ambient temperature. Solar generator efficiency ranged 7.5 % 11.5%. large spread ±1% in instantaneous observed identical values The dependance average temperature is given by a simple relation precision ±0.2%. Load matching optimized for high Averaged over half year period losses non-ideal amounted only 8.9%. Assuming ideal simulated electrolyser, overall hydrogen production 8.0%.
