Embodiments provide solar panels and methods of assembly thereof, permitting operation of a photovoltaic material with reduced degradation. As one example, a solar panel comprises one or more solar cells that include perovskite, the one or more solar cells encapsulated by a film and housed in a glass exterior that is hermetically sealed to maintain a vacuum in an interior of the solar panel of 10.sup.−7 Pascal or less throughout a lifetime of the solar panel. In this way, degradation of the solar panel due to water ingress can be avoided, thereby increasing an operational lifetime of perovskite-based solar panels and reducing manufacturing costs as compared to silicon-based counterparts.

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

A fail proof electrical connector apparatus offers a unique structure for solar photovoltaic (PV) system installations. The apparatus includes a compact connector enclosure that can be installed at flexible locations of a solar module. The tabs of the connector enclosure connect to various solar cells of the module. The insertion pins of the tabs are mounted inside plugs of a pin connector, which connects to a cable. The cable comprises a one-plug end and a multiple-plug end with a wire connecting both. Of the two or more plugs of the multiple-plug end, only one active plug is electrically connected to the wire. The cable is connected to the module with the active plug being inserted to a center plug of the pin connector, and the one-plug end connected to an outer plug of the pin connector of an adjacent module, thus, achieving fail proof, reliable installations while saving labor hours.
