Thanks for that info! I had no idea. Will be checking out MT solar this weekend. I think my big challenge for tue ground mounts is going to be balancing out depth of the postholes vs location, as the the higher up the slope I go (I want to be on the high side for aesthetics), the closer I get to a huge amount of ledge (near-surface bedrock somewhat unique to New England). Gonna be putting a bunch of test holes into a perfectly good blueberry field come May, when it dries out a bit.
My 44kW vertical and bifacial set in Finland.

Catch, make or grow everything you can.
Rent or Buy a good sized hammer drill and bits,
grout rebar into holes drilled into the rock to develop the anchorage you need.
If the rock is fractured/poor quality near the surface, keep drilling deeper. May need a bit extension.
Oh, that's part of the plan, my friend... All a matter of balancing how much of that I want to do with how far down the slope I go to avoid it. I don't mind pinning to ledge for a few posts, but working in a 2-3' hole gets old pretty quick, as I suspect you know all too well. We managed to get the pad and septic done without hitting ledge once, but we sited the house with that in mind. I don't know if I can get that lucky again for the array. Well driller coming to drill in a few weeks and location we're planning for that will tell me quite a bit if the ground will freeze up enough to get the rig in. As my wife says, "We just don't get real winter anymore."

MT Solar isn't cheap plus you have to source SCH 40 or SCH 80 pipe for posts.

The Rain in February is a bit of a mixed good/bad thing, I mean I am not complaining about the mild temperatures, but with them comes Fog and that is messing with my solar!
Heating load is nearly nothing though, can't complain there either.
I am not sure if I should be putting the snow blower away and getting the rototiller ready or what I should be doing!

I bet it doesn't happen often, but I have to say you were correct (just this once though): Yesterday wasn't that perfect after all...
Even with few small clouds interfering I got 190kWh today.
Yeah, I got only 13kW of panels. Got another 8 but not connected - running 3x8 in series now.
I need more panels.
Considering another 24 on top of my carport this spring.Sure, we get 320 days on average with sunshine down here and longer days regd. light ^^ so its easier that way here.

Redoing calculations makes 61,25MWh which is out of my reach by at least 20%. Which reduces my setup from "working much better than expected" to "Meh".Yeah, I got only 13kW of panels. Got another 8 but not connected - running 3x8 in series now.

Damn that's a lot. I'm not even sure if we have that many days in our calendar up here.
192kWh today. Maybe 5-10kWh missing because of clouds. It is getting better every day now and fast.
Got my first full charge of the season this weekend - first one since November. The sun is over the trees and one array is in full sun again.
So as a newbie, I’ve been following this thread with interest/awe.
Out of interest why do you need 192kWh per day? 4.6 GW ? Is your heating bill that high?
Here in the “tropical” south of England
I only need 14kWh ….

204kWh today. 1,3MWh already this month. It is going to help with electric bill for sure.

Look at post #253 and some following posts. You are not the only one asking about this...
Summer consumption is much less, but total is 40-45MWh/year. This winter has been exceptionally cold and snowy.

Of course we do, but you need to cool yourself from time to time in +30C pool.

44kW of PV
making 204kWh in Feb.
Sunrise/set at 63 north, you have 7hours (8:30 - 4:40)
44kW x 7hrs x Eff = 204kWh,
Your system is running 66% efficient in Feb. with stationary panels - well. at least during a sunny day.
That is because N.America exported our winter this year!
(we are calling this "The year without a winter" - it has been raining and we have nearly zero snow on the ground)

We normally run out of the sauna and roll in some nice fresh snow, but we have NO Snow !!Of course we do, but you need to cool yourself from time to time in +30C pool.
