Abstract: A photovoltaic assembly for converting solar radiation to electrical energy is described. The photovoltaic assembly includes a photovoltaic module and an electronic component housing. The photovoltaic module has a frame, a laminate, a plurality of solar cells and a backsheet. The electronic component housing has an upper section to couple to the backsheet, a middle section and a lower section for enclosing electronic components. The electronic components can include a microinverter or electronics for a junction box. The middle section can have a heat sink in thermal communication with the electronic component and an opening. The opening can be a plurality of openings having a plurality of air fins distributed therein, or can be a diagonal or curved structure. The opening can permit fluid communication between the heat sink and an ambient environment. The upper section and/or the aforementioned air fins can also be coupled to the backsheet via a heat conductive adhesive.

Abstract: A photovoltaic module can include an outer surface with an outwardly bulged convex shape. The outer surface can be curved about its longitudinal axis and/or transverse axis. Optionally, the outer surface can be bulged in a generally spherical shape. The convex shape of the outer surface of the PV module can provide the outer surface with additional stiffness, and/or cause water to flow away from the center of the panel toward its edges, thereby reducing soiling caused by accumulated water, debris, and dust and/or other benefits.
