We call Fixed Solar Panels "Cave-Man", as it's the most inefficient Solar Racking for Energy Generation!
The main reason we're Not interested in supplying Fixed Solar Racking (FT), you can Harvest the same daily energy with DART Racking, using less than Half the Solar Panels & Half the footprint than FT Solar Racking!
DART Radiation Tracking is Superior and Generates up to 60% more Energy over 12 months than any FT Racking, as shown in this video, and the Further South of the Equator a DART unit is installed, like Melbourne, it will Generate Energy from 5AM to 8PM.
Ground mounted Racking is easier & Quicker to install if using Ground Screws, as No Concrete is required, allowing installation straight away, Ground Screws are also better for the environment as can be easily removed if you decide to relocate the array!
