| Description | Value |
| Solar collector area, | 25 m2 | Power conversion efficiency, | 30% | Optical efficiency, | 85% | Angular speed of the primary motor, | 120 rpm | Angular speed of the secondary motor, | 120 rpm | Gear ratio of the primary driving mechanism, | 4400 | Gear ratio of the secondary driving mechanism, | 4400 | | AE-STS | PD-STS | HD-STS | Power rating of the primary motor, | 99 W | 99 W | 99 W | Power rating of the secondary motor, | 66 W | 99 W | 99 W |
|

For AE-STS, the azimuth motor has lower power rating due to the movement not against the gravitational pull. |
