<p><P>PROBLEM TO BE SOLVED: To provide a solar battery unit and a method of fitting the unit to a roof, capable of discharging rainwater entering through a gap between the adjacent solar battery units or between the adjacent solar battery unit and a roof tile without reaching the bed surface of the roof when the unit is set on an inclined roof. <P>SOLUTION: This solar battery unit includes: a solar battery module; a module frame surrounding the peripheral edge of the solar battery module to support and the solar battery unit and fit the same to the inclined roof; and a drainage ditch provided along the module frame outside the module frame. When two or more solar battery units are arranged, the drainage ditch catches rainwater entering through the gap between the module frames and discharges the rainwater to the eaves side of the inclined roof. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
