Standard ground mounts use concrete base, ground screw,pile footing to fix solar mounting structures,and then hold solar panels up at a fixed angle. Some standard ground mounted solar panel systems can be manually adjusted a few times a year to account for seasonal shifts of the sun.
Pole mounts support multiple solar panels on a single pole, and elevate panels higher off the ground than a standard ground mount. Pole mounts often adopted in solar pump,home solar systems and other open ground solar projects.
Merits of ground mounting solar
First, ground mounted solar panel systems are very easy to place, because they can be located on open land. They don’t require drilling into your roof, and the bracings used in standard ground mount systems are lightweight and easy to remove. (If you opt for a pole mount, they will usually be installed more securely.)
Second, a ground mount solar panel system can be more productive per panel than a rooftop solar array. Because they’re not dependent on your roof, ground mounted solar panels are set at the perfect angle to optimize energy production. This means you can generate more electricity than a comparably-sized rooftop system, and save more money in the long run.
Finally, ground mounted solar panels are very easy to access for cleaning and maintenance. If you live in an area that receives a lot of snow in the winter, being able to easily sweep the snow off of your solar panels is a major convenience.
Most installers offer a ground mount option, and the cost of standard ground mounted solar is comparable with a rooftop solar energy system installation.
