Manhole- or access cover for e.g. reservoir for water supply, has photovoltaic cell or solar module for conversion of sun light into electrical power, where cell or solar module is mounted on cover surface to be aligned outwardly

摘要

The cover (2) has a connection line (14), and a photovoltaic cell or a solar module (12) for conversion of radiation energy i.e. sun light, into electrical power. The cell or the solar module is mounted on a cover surface to be aligned outwardly. An intermediate space (6) is formed between a cover outer wall (4) and a cover inner wall (5), and the photovoltaic cell or the solar module is arranged in the intermediate space. The cell or the module is arranged below a transparent covering (13), which is made of a break-proof material e.g. safety glass. The covering is partially curved.
