10 × 6.2 W Uni-Solar L-Strip amorphous silicon solar cells 62 W (ideal) for $49 shipped. Vmmp - 1.6 V, Immp - 3.9 A. eff.: 6-7%; 10"x14"
1 × 2' x 7' x .001" FEP front sheet $40 shipped from McMaster-Carr
1 × about 2 square meters of .5mm thick STR Photocap EVA (ethylene vinyl acetate) encapsulant usually, each cell gets sandwiched in two layers of this; half as much was needed because the cell backing is stainless steel. Tedlar (PVF) backsheet was also not needed for the same reason.
1 × about 2 square meters of TPE backsheet Tedlar - Polyethylene - EVA
20 × bendy wires (fine multi-stranded copper, insulated) to solder the cells together and solder them to the power controller (these I can get free)
