TrackerSled Controls and Inverter

Pilot Specific Provisions

A tour of the units that control the trackers' movement and the inverter that connects the TrackerSled pilot to the grid.  

TrackerSled Cabling

Pilot Specific Provisions

The DC cabling extends from the DC optimizers to a transition box, where it connects to the underground wiring feeding the Inverter, located 250 feet away.  This cabling is specific to the pilot and does not reflect a TrackerSled installation at scale

DC Optimizers

Rationale for DC Optimizers

DC optimizers provide granular feedback on each PV Module's production, allowing us to evaluate the benefits of installing a reflective film on the top half of the pontoon skis.

Superstructure Completed

Photovoltaic Modules Installed

After ballasting the pontoon skis with water,  we erected the posts, pivot arms,  and purlins of a commercial single-axis tracker.  We then installed 28 bifacial photovoltaic modules with an aggregate nameplate capacity of 11.2kW,

Mobile Platform In Place

Granor Farm, Three Oaks, Michigan

After months of planning and prefabrication, assembly of the full-scale TrackerSled prototype began at Granor Farm in Three Oaks, Michigan.  Granor Farm is a 400-acre certified organic farm that produces vegetables, flowers, herbs, and grains.  The energy produced by the TrackerSled will power Granor Farm's grain dryer.


Prefabrication and transportation

Delivering the TrackerSled

Relocatable pick points on the box trusses were used to lift the pontoon skis off flatbeds during delivery.  Later, these pick points were relocated so a row-crop tractor can tow the TrackerSled to a different location.
