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.

A solar cell module having high reliability by increasing heat release of a bypass diode is provided. A solar cell panel including a photoelectric conversion unit, a holding member disposed at a periphery of the solar cell panel to hold the solar cell panel, a heat release plate spaced from the solar cell panel and disposed on the holding member, and a bypass diode attached to the heat release plate so as to be spaced from the solar cell panel and electrically connected to the photoelectric conversion unit are included. An attachment surface of the bypass diode to the heat release plate is disposed to face the holding member.

A photovoltaic junction box is disclosed. The photovoltaic junction box comprises a base having a receiving chamber, a cover mounted on the base closing the receiving chamber, and a plurality of ventilation passageways. The plurality of ventilation passageways are disposed between a peripheral edge of the cover and a peripheral edge of the receiving chamber, and communicate between the receiving chamber and an area external of the photovoltaic junction box.

A photovoltaic junction box is provided, including: a box body; a plurality of conduction terminals received in the box body; and at least one surface-mounted diode mounted on the plurality of conduction terminals. Each surface-mounted diode includes a flat body, at least one anode pin extending outwardly from an edge of the flat body, and a cathode pad located on a bottom of the flat body. The cathode pad of at least one surface-mounted diode mounted on a surface of the conduction terminal has a heat conduction angle more than 180 degrees and less than 360 degrees. Since the heat conduction angle is more than 180 degrees, the heat produced by the diode may be rapidly transferred to the conduction terminal in time to avoid deterioration or damage to the diode, improving the heat dissipation rate, and improving the current carrying capacity of the photovoltaic junction box.

An apparatus of a junction box component housed in a junction box and designed to be coupled to a power generator. The junction box component may include one or more bypass mechanisms configured to bypass one or more substrings of the power generator in a case of malfunction or mismatch between the substring and the remainder of the power generators. The one or more bypass mechanisms may generate heat which may be transferred out of the junction box. The junction box component may be designed to conduct the heat towards the base of the junction box and/or the cover of the junction box. A heat dissipation mechanism may be mounted on the base and/or the cover. A bypass mechanism may bypass the entire power generator.
