A photovoltaic assembly includes a photovoltaic panel, two curtains and two rollers. The photovoltaic panel is for converting light into electricity and comprising two opposite surfaces. Two curtains are for absorbing solar heat to roast the photovoltaic panel when the two curtains are disposed to cover the two opposite surfaces of the photovoltaic panel. Each of the two curtains includes a stack of a reflective layer, a high thermal capacity layer and a transparent layer. The high thermal capacity layer is sandwiched between the reflective layer and the transparent layer. The reflective layer is closer to the photovoltaic panel than the high thermal capacity layer and the transparent layer are when the two curtains cover the two opposite surfaces of the photovoltaic panel. Each roller includes a rotatable shaft for rolling each of the two curtains.
