A method for inspecting a solar panel of a solar power station is performed in a controller for an unmanned aerial vehicle, UAV, and includes the steps of: receiving an inspection request for a subset of the solar panels navigating, in a first stage, using radio signals, the UAV to an initial location in a vicinity of a particular solar panel of the subset of solar panels; positioning, in a second stage, the UAV using at least one near field sensor of the UAV; and capturing, using the infrared camera, an image of the particular solar panel.

Inspecting a solar panel using an unmanned aerial vehicle

A photovoltaic system for generating an output voltage that is uninfluenced by varying irradiation, includes a photovoltaic source having an input terminal and an output terminal. The photovoltaic system includes a voltage adding arrangement having a first input terminal and an output terminal. The voltage adding arrangement is connected in series with the photovoltaic source, and includes a first route having a voltage source and a second route as a voltage source bypass. The first and second routes extend between the first input terminal and the output terminal of the voltage adding arrangement. The first and second routes being alternately activateable.

Photovoltaic system

An energy supply system adapted for supplying energy to equipment on a high voltage platform. The system includes a fuel cell and an effectuating capacitor. The system also includes an intermediate storage and supply unit. This unit stores energy from the fuel cell and supplies energy to the effectuating capacitor via an electric transforming unit. A high voltage platform including the energy supply system. An electrical network including the platform. A method for supplying energy to equipment on a high voltage platform.

An element () for making an electric contact to another contact member () for enabling an electric current to flow between said element () and said contact member comprises a body having at least a contact surface thereof coated with a contact layer () to be applied against said contact member. This contact layer comprises a continuous film comprising a laminated multielement material having strong bonds, such as covalent or metallic bonds, within each atomic layer and weaker bonds, through larger bonding distance or for example as van der Waals bonds or hydrogen bonds, between at least some adjacent atomic layers thereof.

Contact element and a contact arrangement

An electrical contact element for electrically connecting an electric device and providing current transmission in an electric device wherein the electrical contact element comprises a metallic body, and wherein at least one contact surface, present on the body, is completely or partially coated with a friction-reducing layer. The friction-reducing layer comprises a metal salt.
