Be sure that you touch on each soldering point. If you miss soldering point, array will not function. Also be sure to leave about 6 inches of slack for connecting blocking diode at end of array.

Place small amount of heat-resistant adhesive on back of each solar cell. Lay masonite pegboard over cells so that it completely covers them. Flip entire configuration over so that solar cell array is now resting on masonite pegboard and plywood is free to work with.

Place solar cell array in direct sunlight and connect positive and negative leads to voltmeter to test array. voltmeter should measure about 9 volts if array is functioning properly. Build frame around perimeter of plywood using 3 or 4- by 3 or 4-inch wood molding.
