Solar trap
This patent describes a solar energy collecting apparatus. It comprises: a light funneling trough including two flat light reflecting surfaces disposed in a face-to-face arrangement having an oblique angle therebetween; a two dimensional Fresnel lens covering the opening of the light funneling trough at the diverging extremity thereof; a photovoltaic panel facing the two dimensional Fresnel lens disposed adjacent to the converging extremity of the light funneling trough; and at least one dual-sided light reflecting planar member disposed radially intermediate the two light reflecting surfaces. The dual-sided light reflecting planar member extending from the converging extremity of the light funneling trough towards the diverging extremity thereof and terminated at a substantial distance away from the plane including the opening of the light funneling trough. Wherein the sunlight entering the light funneling trough through the two-dimensional Fresnel lens is refracted by the two dimensional Fresnel lens and funneled by the light funneling trough towards the converging extremity of the light funneling trough and irradiates the photovoltaic panel.
