Installation speed is a key consideration when selecting a tracker partner. Design efficiencies can add up to time and money saved during the construction phase. This constructability report summarizes a field study completed by Eclipse-M that showcases TerraTrak's efficient design and engineering.
Some key factors leading to a 15% install savings include:
- TerraTrak offers a high degree of adjustability (tolerances) for elevation and N / S alignment,
which helps to reduce quality problems and re-work and speeds foundation installation
- Up to 36” vertical elevation adjustment of the ground screws and A-frames
- Pre-assembly of the motor to the gearbox (slew gear)
- Bushing housing assembly (BHA) parts are kitted (zip tied) for convenience
- Torque tubes can be longer than bay type trackers, extending further than the space between
two piles. Therefore, fewer tubes are required.
- One or two workers can perform most installation operations
- TerraTrak 1P is designed so common construction hand tools can be used for all
assembly steps
