Abstract

Photovoltaic panels may be aggregated in various ways and may be aggregated with the use of a backplane where the backplane comprises electrical connectors positioned to electrically connect the PV panels. The PV panels may have various sizes and shapes and may overlap one or more other PV panels or PV panels being aggregated.

First claim

What is claimed is:

1. A modular photovoltaic system comprising:
a plurality of discrete photovoltaic panels, each of the panels comprising a plurality of photovoltaic cells, each of the panels of the plurality having a light-passing top surface, and each of the panels of the plurality having an outwardly facing panel perimeter;
a discrete solid laminate backplane comprising a plurality of discrete mechanical connectors and a plurality of discrete electrical connectors, the laminate backplane also comprising a plurality of discrete electrical connection points on a first side of the laminate backplane, the laminate backplane further comprising two or more layers adhesively connected to one another to form the solid laminate,
wherein each panel of the plurality of panels is electrically and mechanically connected to an electrical connector of the plurality of electrical connectors,
wherein the panels of the plurality of panels are configured to be secured to the backplane via at least one mechanical connector from the plurality of mechanical connectors, the plurality of mechanical connectors securing the panels of the plurality of panels with a spacing between a bottom planar surface of the panels of the plurality of panels and a top planar surface of the backplane, the mechanical connector being one or more of a snap-fit type connector, or a friction-only type connector, or a male-female connector, or a hook and loop connector, and

wherein the spacing varies in height between the bottom surface of the panels of the plurality of panels and the top surface of the backplane.

2. The system of claim 1 wherein the electrical connection points are accessible through one or more vias in the backplane.

3. The system of claim 1 wherein each panel comprises a sealing flap, wherein the panels are positioned along the backplane and overlap each other along at least one panel side, and wherein the panel sealing flap is positioned at each overlap of panels.

4. The system of claim 1 wherein the plurality of electrical connectors comprise ribbons, the ribbons embedded in the laminate backplane beneath one or more of the electrical connection points.

5. The system of claim 1 wherein the backplane has a planar front surface, the planar front surface comprising at least three mechanical connectors from the plurality of mechanical connectors and wherein a first panel is mechanically connected to at least one of these three mechanical connectors and a second panel is mechanically connected to at least one of these three mechanical connectors.

6. A modular photovoltaic system comprising:
a plurality of discrete photovoltaic panels, each of the panels comprising a plurality of photovoltaic cells, each of the panels of the plurality having a light-passing top surface, and each of the panels of the plurality having an outwardly facing panel perimeter;
a discrete solid laminate backplane comprising a plurality of discrete mechanical connectors and a plurality of discrete electrical connectors, the laminate backplane also comprising a plurality of discrete electrical connection points on a first side of the laminate backplane, the laminate backplane further comprising two or more layers adhesively connected to one another to form the solid laminate,
wherein each panel of the plurality of panels is electrically and mechanically connected to an electrical connector of the plurality of electrical connectors,
wherein the panels of the plurality of panels are configured to be secured to the backplane via at least one mechanical connector from the plurality of mechanical connectors, the plurality of mechanical connectors securing the panels of the plurality of panels with a spacing between a bottom planar surface of the panels of the plurality of panels and a top planar surface of the backplane, the mechanical connector being one or more of a snap-fit type connector, or a friction-only type connector, or a male-female connector, or a hook and loop connector,

wherein mechanical connectors from the plurality of mechanical connectors are positioned in the backplane, the mechanical connectors from the plurality of mechanical connectors each mechanically connecting the backplane to a panel of the plurality of panels, and
wherein the spacing between the bottom surface of the panels of the plurality of panels and the top surface of the backplane has a triangular cross-section.

7. The system of claim 6 wherein the electrical connection points are accessible through one or more vias in the backplane.

8. The system of claim 6 wherein each panel comprises a sealing flap, wherein the panels are positioned along the backplane and overlap each other along at least one panel side, and wherein the panel sealing flap is positioned at each overlap of panels.

9. The system of claim 6 wherein the plurality of electrical connectors comprise ribbons, the ribbons embedded in the laminate backplane beneath one or more of the electrical connection points.
