A system includes a roof deck having a slope of 0.25 inch to 3 inches per foot and a roofing membrane is composed of a first material, and at least one photovoltaic module installed on the roof deck. The photovoltaic module includes at least one solar cell, an encapsulant, a frontsheet, and a backsheet. The backsheet includes a head flap located at a first end of the backsheet, and a bottom flap located at a second end of the backsheet. The backsheet is composed of the first material. At least a first portion of the head flap is attached to the roofing membrane, and at least a second portion of the bottom flap is attached to the roofing membrane.

A method of forming an asphalt mixture includes mixing a polyol with a bio-source material to form a bio-asphalt. The method can further include mixing the bio-asphalt with a bitumen source different from the bio-asphalt to form an asphalt mixture. The bio-source material can include an oil, such as a vegetable oil, an animal fat, or any combination thereof. The bitumen source can include a petroleum-based asphalt. The method can further include adding a modifier, such as a fatty acid, a polycarboxylic acid, a polyacrylic acid, a polyacrylate comprising a copolymer, or any combination thereof. Moreover, a roofing grade asphalt mixture includes a bio-asphalt. The bio-asphalt includes an alkyd, wherein the alkyd is a reaction product of a polyol and a bio-source material. The roofing grade asphalt mixture further includes a bitumen source material and particles.
