FAQ: What is the process to learn if the Tracker will work at my home or business?

If you are curious about a Solaflect PV Tracker for your home or business, please contact us to schedule a free site evaluation. During a site visit we will answer any questions you have, assess solar conditions, review the condition of your circuit breaker, and check for other aspects such as the presence of ledge that may affect the Tracker’s installation.

The more sunlight that falls on the Tracker, the more productive it will be, and the more value you will receive from it. We use either a Solmetric SunEye or Solar Pathfinder to measure the “solar access” on your property. This is a measure of the percentage of open sky vs. trees/ridgelines/buildings/etc. that block sunlight at any particular location. More solar access means more sun for the Tracker. Read more

FAQ: How does the Tracker produce more energy? Part 3, shed snow automatically.

In Vermont and New Hampshire, snow is a regular part of life for a significant portion of the year. A solar panel with snow on it will not produce much, if any, energy.

If you have a fixed-mount solar array, you either need to be able to safely access your panels to brush them clean, or leave snow on them until it melts off by itself. Depending on the weather, this might take weeks to happen. Read more

FAQ: How does the Tracker produce more energy? Part 2, face directly at the sun.

Facing directly at the sun means receiving the maximum of the light’s energy. Sunlight falls on a fixed-mount solar array from an indirect angle at all times of the year except two moments. (The precise moments will depend on the tilt and orientation of the array. The ideal fixed-mount array will be perpendicular to the sun only at solar noon on the two equinoxes.) A seasonally adjusted array that has a different tilt for the summer and winter halves of the year will be perpendicular to the sun at only four moments.

Because of this indirect angle to the sun, some of the potential light is lost. Some passes by altogether, and some reflects off as glare. Read more

FAQ: How does the Tracker produce more energy? Part 1, longer days.

During the summer half of the year—from the day after the spring equinox to the day before the autumn equinox—the sun is rising out of the northeast and setting in the northwest (in the northern hemisphere). The “ideal” fixed-mount solar array is oriented due south, since that is the way that it will produce as much energy as it can. However, any time the sun is in the northern half of the sky, which occurs in the morning and afternoon for half of the year, the sun will then be behind the fixed array. Read more
