I am a big fan of Krinner. We use them in a hurricane prone area in the
Northeast. Our projects are much smaller though. You can buy an
adapter for a Bobcat or backhoe to drill them down. The key to that is
keeping them vertical. Chris

We just completed a system on fairly steep ground (probably 25 degree
+-) using ProSolar Groundtrac but with Krinner ground-screws.
ProSolar referred us to an engineering firm to validate. The
engineers said if we had used the standard concrete footing method we
would have had to double the depth to 60", but that ground-screws
would work fine. The engineering report was very affordable. Contact
me if you want a referral.
