  • Patent number: 12199206
    Abstract: Apparatus, systems, and methods for designing photovoltaic panels are described herein. The photovoltaic panels are composed substrings of photovoltaic cells. The substrings of photovoltaic cells may be oriented in a horizontal fashion with respect to a layout of the photovoltaic panels. In the event of snow coverage, partial shading, mutual shading, and so forth, orienting the substrings of the photovoltaic cells in this manner enables those substrings which are disposed higher up in the photovoltaic panel to resume operation even while those substrings which are disposed lower down in the photovoltaic panel remain covered, shaded or otherwise blocked or impeded from functioning. Accordingly, the overall productivity of a photovoltaic panel designed as described herein is increased. Related apparatus, systems, and methods are also described.
