There is disclosed a photovoltaic solar panel capable of clearing accumulated ice. The panel includes a plurality of photovoltaic cells arranged in a plane with an overlaying glass sheet. The glass sheet has a first side towards the photovoltaic cells and a second side having a flat planar surface. The panel further includes an electrical heating web on the first side of the glass sheet between the sheet and the photovoltaic cells. The electrical heating web is configured to heat the first glass sheet sufficiently to melt the ice where it contacts the flat planar surface to cause the snow and ice to slide off the photovoltaic solar panel when the photovoltaic solar panel is at an angle from the horizontal. The electrical heating web is thermally separated from the photovoltaic cells by a transparent layer of low thermal conductivity.
