<p>The group has a set of photovoltaic panels electrically connected together in series and/or in parallel manner. Conversion units are electrically connected to one of the photovoltaic panels to convert direct electric current from the photovoltaic panels into alternating electric current for delivering the alternating electric current to an electric network of a user, where each one of the conversion units includes an inverter. Faces of each photovoltaic panel comprise layers made of transparent plastic material that is obtained by cooling a mixture comprising a polymer material.</p> |
