first solar array tilting

Our solar arrays were installed this June by Ag Technologies of Rochester, IN. Their SolarCAM(R) system allows us to tilt the arrays four times per year to maximize solar production. As the sun appears lower on the horizon in the fall and winter, we tilt the arrays up (steeper) to be perpendicular with the rays.

We actually like that the system is not automated. That would mean moving parts and motors, parts that will inevitably fail and need to be replaced. If you can put up a pop-up camper, you can tilt these arrays.

Interestingly enough, the tilting schedule is not evenly spaced across the year. We tilt on or around August 24 (37 degrees), October 7 (45 degrees), March 20 (back to 37 degrees), and April 18 (12 degrees). This is a function of the sun’s altitude on the horizon. All of these values can be calculated for any zip code, at any date in the future at this Navy website. Your tax dollars at work!

I’m blessed to have an ecological intern this fall from Ancilla College’s Earn to Learn Scholarship Program. I’m looking forward to working with Trace, providing him with a diverse set of experiences, and getting some extra jobs done that have been on my to-do list. We didn’t waste any time… after we met each other yesterday, we went right out to the fields to get tiltin’…
