Wow, William. Thank you for all the details. One size clearly doesn't fit
all! I like the page with all the different wire management options you've
used. Somebody tell me why we still don't have this taken care of WITH the
racking... Shesh.
Blessings,

Ground mount racking choice is determined on a case-by-case basis. If the
ground is flat and area plentiful, we use ballasted on gravel (Dyno-Raxx). If
you need to seasonally adjust, we like the DPW MPM. If the ground is sloped
other than gradually south, top of pole mounts may be
Great. Many thanks, Jerry!

We use holes with concrete for a small array its less expensive

Thanks for your reply, Jerry. How do you attach them to the ground? Concrete?
Driven?

Hi,
We are looking to install some 4KW ground mounted arrays. What racking are you
using? Best ground connection? Wire management? The shows have so many
choices, and I keep doing the same ol thing...

I'd 2nd Hilton's comments. Energy efficiency can reduce heating loads
to almost nothing. The German standard "passive solar" design uses
almost R100 insulation, triple pane Lo E windows, doors with multiple
seals, and are so tight they require an air to air heat exchanger to
insure fresh air.
I've done a couple of load profile studies for heat pumps and solar and
unless the load is primarily air conditioning it's a bad match. Ground
sourced heat pumps in general only pencil out if there is a big air
conditioning load.
The only time I'd recommend a heat pump with an off grid system
