Mounting Hardware
Mounting Hardware
Most mounting systems now have evolved to using simple non-corrosive extruded
aluminum rails with all stainless steel hardware. They go together fast, securely, and
unobtrusively. A great variety of flush, tilt-up, low-profile, high-profile, ground, roof, wall, RV,
and pole-top mounts are available that can be configured to meet almost any need on
almost any surface.
We carry an impressive stock of the most used Uni-Rac, Pro-Solar, and Direct Power &
Water products, with other options and product lines readily available. If you don't see what
you need, or need help figuring out what you need, please give us a call or drop an email.
To Track, or Not To Track?
If you can make your PV modules face directly at the sun and follow it across the sky, both
logic, and real-world experience say you'll harvest more energy. In summer, particularly in
latitudes closer to the equator, when the sun is making a big high arc overhead, you can
gain 30% to 35% more energy. Often, this is the only way to boost solar pump output, and it
happens at the time of year when more water is usually most appreciated.
However, we are not generally fans of tracking mounts beyond the occasional water pump.
With moving parts, there will inevitably be maintenance, particularly with the
electrically-driven models. Experience has shown that you can practically depend on
having to repair something every year. The heat-driven models are more dependable, but
they can get blown off course by winds over 10 mph, and the wake up-roll over-face east
move happens very slowly in cold weather. Finally, all tracking mounts have a cost
problem. In the past ten years, PV modules have halved in cost, tracking mounts have not.
They just don't make good economic sense anymore. You want more power and no
maintenance? Just buy an extra module or two, put them on fixed mounts, and you'll never
need to mess with them again.
