The application relates to a hybrid solar element (100) for collecting solar radiation. The hybrid solar element comprises a transparent front cover (102), a photovoltaic structure (204), a heat exchanger (208), and a back cover (116). The front cover is configured to permit the solar radiation to penetrate inside the hybrid solar element. The photovoltaic structure comprises photovoltaic cells (106) configured to convert the solar radiation into electricity. The heat exchanger is configured to circulate a heat transfer fluid within the heat exchanger and to transfer heat from the photovoltaic structure to the heat transfer fluid. The hybrid solar element further comprises a thermoplastic spacer (218) between the front and back covers (102, 116), which thermoplastic spacer is configured to attach the front and back covers to each other and to insulate the photovoltaic structure hermetically to protect the photovoltaic structure.
