Ground mounted frames, can be an excellent alternative for times when roof space is limited, or the client would like the option to "add on" in the future.
We recently completed the installation of a 5.2kWp grid tie solar system in Christchurch on a ground mounted frame.
The client wishes to add on another 5.2kWp grid tie system in the future, so that he has a 10.4kWp size system in total.
Generally our clients choose to fit the panels to their roof, as it is usually cheaper and they don't necessarily have the space on the ground to place the panels.
Our ground mount frames are very strong and are engineered to handle very high wind zones, making them an excellent choice when roof mounting is just not an option.
