PV Production – Part 2

I have been looking at the production of three different PV systems – tracker, roof, and pole mounts. A roof mount is the least expensive option because the infrastructure for the mount is already in place. Pole-mounts are usually the next least-expensive option, since the mounting equipment is fairly simple to manufacture and install. The trackers are the most expensive, due to the complexity of the tracking system. However, these units produce significantly more power then either of the other two types of systems.

tracker1The graph shows the production of these types of systems since June 2014, normalized to account for differences in array size. As you can see, the trackers have produced around 44% more than a roof system, and 26% more than a pole mount. Winter production of the tracker is where these units out-perform the others.

If you would like more information about trackers, or any other type of renewable energy system, please contact us. We look forward to helping you!
