Abstract: A solar panel construction for use in a weatherized interlocking solar panel array system, and a solar panel installation kit for installing frameless solar panels onto a battened roof or support structure, are disclosed. The solar panel array system comprises at least two rows and two columns of solar panel constructions (i.e., solar panel constructions arranged in a side-by-side fashion) interconnected together and installed on a roof or support structure, wherein the rows of solar panel constructions sealingly overlap one another (by means of a flexible rubber or elastomeric strip fitted into the upper tracks of the constructions) and the columns of solar panel constructions interconnect with one another (by means of opposing forward and rearward extending side track fins, which fins are spaced apart and parallelly nest/fit together to form an elongated water trap between adjacent panels). The solar panel installation kit comprises two specialized tracks and two brackets.
