Power device used in e.g. railing, has collector surfaces arranged parallel and opposite each other to collect solar energy from all sides of power device

摘要

The device includes solar panels supported in vertical position by a suitable frame. Each solar panel has a first collector surface for collecting direct radiation of solar energy, and a second collector surface arranged parallel and opposite to the first collector surface for collecting solar energy. The collector surfaces are arranged to collect solar energy from all sides of the device.
