Abstract: The present invention relates to a computer-implemented method of providing technical sizing parameters for an energy supply system supplying electrical energy to an installation connected to a public grid subject to potential service interruptions, said computer-implemented method comprising the steps of: ?entering electricity consumption chronology (S1) of said installation; ?entering photovoltaic production capacity limits and energy storage unit capacity limits (S9); ?estimating a ratio (S11) of self-sufficiency or of self-consumption, or of internal rate of return; ?displaying (S13) a plurality of energy supply system configurations on user interface means; wherein each configuration is associated to a sensitivity parameter, said sensitivity parameter enabling to determine the optimized technical sizing parameters of the energy supply system regarding the reliability of the public grid.

Abstract: A photovoltaic panel is provided, including a plastic support sheet having a cellular core; a laminate of photovoltaic cells fixed to the support sheet; and a plastic and/or composite frame including longitudinal profile sections for laterally protecting the laminate of photovoltaic cells and the support sheet, and corner-shaped portions connecting the longitudinal profile sections together in order therewith to form a closed frame.
