Dual Axis Tracker Project in Kamloops

Updated: July 23, 2017

The largest dual axis solar tracker is being installed in the Kamloops region right now. This tracker will follow the Sun throughout the day and change tilt to maximize power production. A dual axis tracker can produce 40% more electricity per year than a static or fixed array. This is what are we building. It is made in Ontario by Sentinel Solar and goes by the name Sentry.




This tracker will hold 45 Silfab 280 Watt bifacial modules. These modules are made in Canada. Bifacial modules are semi-transparent and capture solar energy on the flip side too by taking advantage of the albedo effect. The nameplate rating is 12.6 kW. The array uses high-efficiency micro-inverters made by Enphase.

The project is being installed on Westsyde Road in Black Pines. It is big! Here's the truck that delivered the equipment on Monday.


The foundation work is also massive and composed of concrete and lots of rebar. Engineering of the foundation was required. This photo will give you an idea of how this tracker will be fastened onto the ground.


We estimate that this tracker will make over 25,000 kWh/year of power. To get all of that juice to the house of our client, serious wire is needed.


Assembly of the tower and supports will start soon, and a video of the process can be seen here.


The foundation work has now been poured.



Amie Schellenberg and her husband Ryan of Lodgepole Electrical finished mounting today the 45 Silfab bifacial modules and micro-inverters onto our big dual axis tracker project in Black Pines BC. A crane will lift this onto the base as one piece.



The modules and inverters are now wired and the tracker is ready for the big crane lift.



Sweet Spot Solar CEO Michael and electrician Amie Schellenberg were on-site today.





Here's what the tracker looks like when mounted. A few more adjustments are needed and some fine tuning of the communications system and this baby will begin making power.







This tracker is a powerhouse! For example, by 11:15AM on July 23 it had already produced more than 30 kWh for the day which is enough to power an average house for an entire day.
