文摘

Analysis of experimental data of 2 different PV-PCMs considering actual electricity prices on the EPEX spot market. Considering higher EPEX prices in the morning provide better results than accounting the sum of daily generated electricity. At the tests, higher morning EPEX electricty prices are not sufficient for profitability of yield increase by standard PCM. PCM with high thermal conductivity is more appropriate for PV than conventional PCM.
