A system includes a plurality of storage brackets installed on a roof deck, each including a base plate, an arm and optionally a head and a receptacle. The arm is optionally rotatable. The receptacle of one of a first pair of storage brackets is configured to receive the head of another of the first pair of storage brackets. The receptacle of one of a second pair of storage brackets is configured to receive the head of another of the second pair of storage brackets. The first and second pairs of storage brackets are spaced apart from one another. The brackets are configured to receive at least one roofing material, which is positioned on the base plate of at least one of the first pair of brackets and at least one of the second pair of brackets.

The present disclosure relates particularly to photovoltaic roofing systems for use in photovoltaically generating electrical energy, specifically, the use of bottom flashings in such systems. Methods for installing such systems and replacing non-photovoltaic roofing elements in such systems are also described.

A roofing shingle includes a head lap and at least one solar cell. The head lap includes at least one handle located between a first end and a second end of the shingle and proximate to a first edge thereof. The at least one handle includes at least one cutout and a gripping portion. The at least one cutout is sized and shaped to receive an external object to facilitate transporting the shingle by a user.

A method of making a photovoltaic module includes the step of obtaining a frontsheet having a glass layer, a light scattering encapsulant layer, and a polymer layer. The light scattering encapsulant layer includes a first region, a plurality of first portions extending from the first region, and at least one area located between the first portions. The first portions of the light scattering encapsulant layer has a first light scattering value and a second portion defined by the area has a second light scattering value different from the first light scattering value. The method includes the steps of obtaining at least one solar cell, an encapsulant, and a backsheet, and laminating the frontsheet, the encapsulant, the at least one solar cell, and the backsheet.

Disclosed is a solar cell string, a string group, a module, and a manufacturing method thereof. The solar cell string is formed by connecting a plurality of first type of solar cells and at least one second type of solar cell, wherein front electrodes of the plurality of first type of solar cells (701) have the same polarity, back electrodes of the plurality of first type of solar cells (701) also have the same polarity, and the polarity of the front electrodes of the first type of multiple solar cells (701) is opposite to the polarity of the back electrodes. Back electrodes on a back side of the second type of solar cell (801) comprise a positive electrode and a negative electrode. The solar cell string utilizes two structures of solar cells to establish a stacked connection of shingles, thereby enabling a current carrying unit to direct current out of the back side of the solar cells, making it easier to incorporate a diode, causing no size increase in the module area, reducing the wafer breakage rate, and accordingly raising the module pass rate and assembling efficiency. Further disclosed is a string group formed by the solar cell string, a module, and a manufacturing method thereof.

A method of manufacture of a photovoltaic solar roof tile assembly can include forming a laminated structure by laminating one or more sheets that include at least one photovoltaic solar cell, and attaching a junction box to the laminated structure to form a photovoltaic solar panel. The junction box can include a first DC connector and a second DC connector. Attaching the junction box to the laminated structure can include sealing the first DC connector to the laminated structure. The method of manufacture can include forming a roof tile with a hole that extends from a front side of the roof tile to a rear side of the roof tile, and locating the junction box in the hole by inserting the first DC connector from a front side of the roof tile and attaching the second DC connector from the rear side.
