A system for supplying energy is provided. The system comprises a shelter for users of an outdoor recreational area. The shelter has a roof portion and photovoltaic cells disposed on the roof portion, the photovoltaic cells being arranged to convert solar energy into electrical energy. The system also comprises an energy distribution system arranged to receive converted electrical energy from the photovoltaic cells, and to receive grid electrical energy from a power distribution network. The energy distribution system is arranged to provide converted electrical energy to an electrically powered component of the system at times when there is sufficient converted electrical energy to power the component, and to provide grid electrical energy to the component at times when there is insufficient converted electrical energy to power the component.
