More expensive than a rooftop solar system Great way to bypass any roof issues, existing or potential (limited space, structurally weak roof, etc.) Pros and cons of ground-mounted solar panels Pros Here’s what to consider if you’re thinking about going solar with a ground-mounted solar panel installation. What are the pros and cons of ground-mounted solar panels?

On the flipside, pole mounts with tracking systems have a higher cost per watt, and most people find it cheaper to instead install a standard ground-mount array with more solar panels. Another advantage of pole mounts is that they can easily incorporate a single-axis or dual-axis tracking system these enable the panels to follow the sun over the course of the day and thus produce more energy.
Pole-mount systems offer greater clearance from the ground, which is useful in avoiding foliage or other ground obstructions, and can even be used to provide space and shelter for animals to graze underneath. A large pole is set into the ground, upon which you connect your rails and mount your solar panels. To build a pole-mount solar system, you dig one big hole into the ground, instead of several smaller holes as with a standard ground-mount. The standard ground-mount system is the easiest and most cost-effective solution for a ground install, and also the most common.

Standard ground mount systems typically hold the solar array in a fixed position, although options for manual adjustment are gaining popularity. The exact method of anchoring will depend on your ground conditions: using concrete piers is most common, but driven piers, helical piles, and concrete ballasts are options, as well. Standard or traditional ground mounts use ground anchors to hold up a racking table that supports the solar panels on rails. You can use either a standard ground mount, which fixes the panels in one place, or a pole mount, which puts them higher off the ground. What are the different types of ground-mount solar installations? Ground-mounted solar panels are also known as backyard solar panels, free-standing solar panels, and ground-mount PV systems. Meanwhile, larger-scale ground-mounted systems, like ones used in solar farms, tend to use larger, 72-cell solar panels. Residential ground-mount solar installations are generally built using 60-cell solar panels - the same solar panel size typically used in residential rooftop solar installations. The panels feed power to a solar inverter, which is located either on the mounting system behind the panels or in the house.
The panels can be placed anywhere from a few inches to a few feet off the ground, depending on how the racking system is set up. Ground-mounted solar panels can be installed any place on your property that has sufficient open space and good sun exposure. What is a ground-mounted solar panel system?Ī ground-mounted solar power system is just what it sounds like - a system of solar panels that are mounted on the ground on your property, rather than on the roof of your house.
