    Abstract: A thin film photovoltaic module that is connectable to a terminal includes a first glass sheet defining a sun facing surface and a second glass sheet defining a back facing surface opposite the front side surface. The second glass sheet includes a feed-though opening extending through the second glass sheet. A photovoltaic material is between the first glass sheet and the second glass sheet. An encapsulant material is between the first glass sheet and the second glass sheet that bonds the first glass sheet and the second glass sheet together and seals the photovoltaic material from moisture. A conductor is electrically connected to the photovoltaic material at one end. The conductor passes through the feed-though opening. A reinforcing member is disposed on the sun facing surface of the first glass sheet. The reinforcing member has a footprint hanging over at least a portion of the feed-through opening.
