Solar+Power

= Energy From the Sun = Contact **Joe Duval** for advice on project and interview on how to construct a solar panel for $120. He has an interest in educating on a energy "games" as competition.

Mould:
- divinycel foam with fibreglass laminated on both sides - something flat (large, thick piece of MDF) coated with shellac if necessary - easy wax for flat surface (want to reuse mold? use release agent - Poly Vinyl Alcohol) - kitchen sponge and hair dryer for release agent

Vacuum Bag:
- vacuum pump (venturi) - sheets of plastic - polyethylene can be bought at a hardware store (clear) - Dum Dum (super BluTak - comes in a roll)

To Remove Excess Resin:
- peel ply large enough to cover divinycel sheet - sheet of perforated film large enough to cover sheet - bleeder cloth large enough to cover sheet

- (6mm) divinycel of correct dimensions (as least 20mm margin for cutting) - small piece of wire to poke holes in divinycel 5-8 cm apart - resin - 350 grams to make a 512 x 614 finished sheet - brush for resin - 60GSM surfboard fibreglass (2 sheets) - jigsaw with hacksaw blade (set on fast with little forward angle)

Drill the Holes:
- each panel needs 5 holes/cell (precisely placed- maybe with a template) - use larger drill bit (eg 6-9 mm) to deburr drilled holes - mark panel with 102mm squares centered - 3M VHB Double Sided Tape Y9473 (Blackwoods 01302224) - maybe also with Sikaflex 227 (important to seal sides so that not too much conformal gets under the cell)

Tab the Cells:
- tabbing ribbon (Tinned Copper Interconnect Ribbon, ETP Copper Strip Annealed Temper, .005 x .080 + 1 -.003, 60/40 Brookescoat .0004 to .0006 in from E. Jordan Brookes)
