First Claim
1. A method of manufacturing a frame-less epoxy-resin encapsulated solar power panel along a solar power panel production line in a solar panel factory system, said method comprising the steps of:
- (a) supplying a stack of phenolic resin support sheets to a conveyor transport system of a solar power panel production line, wherein each said phenolic resin support sheet is made of non-conductive and reinforced phenolic resin material, and has a top surface and a bottom surface;
(b) applying an optically transparent layer of adhesive coating material to the top surface of one said phenolic resin support sheet;
(c) placing an array of photo-voltaic (PV) solar cell modules connected to an electrically-conductive bus bar assembly on said optically transparent layer of adhesive coating applied to the top surface of said phenolic resin support sheet,wherein said optically transparent layer of adhesive coating material has a thickness equal to said array of PV solar cell modules so that the top surfaces of said PV photo cell modules and surrounding adhesive coating material reside in the same plane so as to form a planar surface;
(d) applying an optically transparent epoxy-resin encapsulating layer over said planar surface formed by said array of (PV) solar cell modules, said electrically-conductive bus bar assembly and said optically transparent layer of adhesive coating material;
(e) partially curing optically transparent epoxy-resin encapsulating layer applied over said array of PV solar cell modules, said electrically-conductive bus bar assembly and said optically transparent layer of adhesive coating material;
(f) placing an optically transparent plastic sheet of polycarbonate material on said partially-cured optically transparent epoxy-resin encapsulating layer so that said optically transparent plastic sheet of polycarbonate material securely bonds to said partially-cured optically transparent epoxy-resin encapsulating layer;
(g) applying an optically transparent epoxy-resin top coating over said optically transparent plastic sheet of polycarbonate material, for providing self-cleaning action when wet during rain showers;
(h) curing optically transparent epoxy-resin top coating applied over said optically transparent plastic sheet of polycarbonate material;
wherein a high-strength edge portion is formed all around the perimeter of said frame-less epoxy-resin encapsulated solar power panel construction, between said optically transparent epoxy-resin top coating and said phenolic resin support sheet; and
wherein said high-strength edge portion of said frame-less epoxy-resin encapsulated solar power panel construction is free of said array of PV solar cell modules and said electrically-conductive bus bar assembly so that mounting holes can be drilled through said high-strength edge portion without the risk of damaging said array of PV solar cell modules and said electrically-conductive bus bar assembly, and without the risk of compromising the strength and integrity of said frame-less epoxy-resin solar panel construction;
(i) mounting an electrical connector to the bottom surface of said phenolic resin support sheet;
(j) testing said frame-less epoxy-resin encapsulated solar power panel construction under an artificial-sun light source, and determining that said frame-less epoxy-resin encapsulated solar power panel construction meets a set of minimum electrical and mechanical performance specifications; and
(k) packaging each said frame-less epoxy-resin encapsulated solar power panel construction produced from said solar power panel production line of said solar panel factory system.

Abstract
A solar panel factory system and process for manufacturing a frame-less epoxy-resin encapsulated solar power panel by encapsulating solar cell modules on a phenolic resin sheet beneath a polycarbonate panel using an optically-transparent epoxy-resin material. During solar panel manufacture, an optically transparent epoxy-resin coating is applied over an array of photo-voltaic (PV) solar cell modules mounted on the sheet of phenolic resin, and supported in a layer of adhesive coating is applied as a liquid with a viscosity and a thickness such that the thickness of the layer of adhesive coating is substantially equal to the thickness of the PV solar cell modules, and cured to a sufficient hardness. The epoxy-resin coating applied over the array of PV solar cell modules, and the cured layer of adhesive coating, reinforce the strength of the sheet of phenolic resin, particularly around the perimeter of the frame-less epoxy-resin encapsulated solar power panel.
