The oven is made of a wooden box with a heater I took from a paint remover.
I used a picaxe micro controller to monitor temperature.
It drives a ralais switch to switch the heater on and off.
I also control the vacuum pump (as the vacuum bag leaks) using the picaxe. The microcontroller switches the pump on and off based on a time interval controlled by analog input. Another method is using a small switch in the vacuum bag. If the vacuum is reduced, the switch is triggered.

Choosing either silicone or EVA both require heating and compressing (using vacuum). So I had to build a vacuum oven.

These can be ordered online, or bought from chinese manufacturers directly (usually in significant quantities). There are a number of Ebay sellers who do not guarantee their wares. Cells can easily yield less than advertized. Cost (aug 2010) is about 1 Euro/Watt. A nbit about cells [[http://www.sunreign.com/info/EbayCells here]].

Encapsulation is what protects the cells against corrosing and kinetic damage. It can be anything, but in this well organized world it is not always easy to get that anything. EVA, Ethyl Vinyl Acetate, most commenly used, is not for sale for real prices, all the other parts you need to make a regular panel are priced such that you end up on a par if you don't count labour cost.
