Embodiment Construction

[0064] Although the principles of the present invention are applicable to PV modules based on different semiconductors, the ensuing description applies to a unique type of PV module based on very thin, elongated solar cells that are also bifacial and produce half- Flexible to flexible modular assemblies.

[0065] There are known processes by which elongate solar cells can be manufactured. As used herein, the term "elongated solar cell" refers to a solar cell that is roughly in the form of a parallelepiped and has a high aspect ratio due to its length being significantly greater than its width (typically tens to hundreds of times larger). The thickness of an elongated solar cell is largely immaterial to the invention, but is typically one-quarter to one-hundredth of the cell width. The length and width of the solar cell define the maximum active (or effective) surface area available for power generation (the active "face" or "faces" of the solar cell), while the length and thi...

Abstract

The invention relates to a deployable solar panel system. Concretely, the deployable solar panel system (300) includes a plurality of solar cell panels (200) that are mechanically and electrically coupled to each other prior to shipment to an installation site (400), folded in a stacking arrangement within a packaging container (330) for shipment to the installation site, and then unfolded to deploy the solar cell panels (200) at a desired tilt angle (A1, A2) during installation at the installation site. In one embodiment, the solar cell panels (200) are mechanically coupled to each other using a hinge assembly (301), such as a hinge bracket (304) and hinge pin (306). Each solar cell panel system (200) is electrically coupled to each other using a series string (316). The series string (316) may be electrically coupled to a DC-DC converter (314) and / or a DC-AC inverter (318).

Description

technical field [0001] The present invention relates to the installation of solar panels (or called solar panels), and in particular to a system and method for installing solar panels on low-slope surfaces such as commercial building roofs. Background technique [0002] Currently, there are approximately 11 billion square meters of commercial roof surface available worldwide. Unlocking even a small fraction of this potential will have a major impact on the world's energy needs. [0003] On commercial building roofs, which typically have no or low slope, specialized substructures are used to mount the modules at the desired slope angle, which adds additional weight to the roof. Installing a solar array on an existing residential building generally does not present additional weight issues because typical residential substructures are built to withstand heavy snow and to be able to support framed solar modules and mounting structures. However, when working on commercial buil...
