Module Comparison diagram
| Competitors’ | Sensor Controls’ | |
| Materials | bismuth Antimony Tellurium | |
| Wastes in process | large amount (up to 60 %) | very few (up to 10 %) |
| Material’s shape in process | Ingot or disk shape |
Needle, mono-crystallized 2mm in diameter, 120 mm length  |
| Total estimation | *Large amount of wastes for 3 times cutting in process. *Short life for *Sandwitch frame structure. *Slow temperature rise/fall. *Low(No) reliability *Coefficient of Performance did *not increase more than 20 years. |
* Only 1 time cutting in process, very few wastes. * Long life for * center frame structure * Fast temperature rise/fall. * High reliability * Coefficient of Performance increased 25%. |
| Future vision | No reliability makes the market smaller. Too much wastes are not state of the art. |
