I can help with the cost itemization. I pulled the invoices and receipts from my archive.
Gwen’s hookup was $982 – see attachment Invoice 1749
Greenhouse invoice of $1400 was for the electric hookup (conduit, wire, trench) and root cellar insulation (foam).
Root cellar:
Labor @ $35/hr – 5hrs $175
Material (froth pack, respirator, goggles, Tyvek suit – receipts included with the invoice 1751 pdf ) - $790
Total: $965
Greenhouse electric hookup:
Labor @$35/hr – 9hrs $315 (I’m definitely cheaper than excavator)
Material (conduit+little bit of wire, because we re-used the one which was there) $120
Total $435
Gwen, I asked for the receipts, because we paid our condo fees into the account that paid for a lot of things. Our budget was pretty simple so it shouldn’t be too difficult to check that against the account statements.

The question about safety and adequacy would be best answered by professional electrician, I think the disagreement lies somewhere else.
Yes, the cable could be used to supply the power to the Earthship from your house.
The book keeping – I don’t blame you for anything, I didn’t see enough info yet to draw any conclusions.
We all spent countless hours working for the community and few are paid, most are not.
As to people convincing you to keep the existing solar setup, I found this.

That's what I thought. We can talk to Brad this morning. I'll try to be there as soon as I can so the debate is short. Yesterday was a hard day for everyone, I think,

Hi Gwen,
The little junction box with the thick wire is temporary. We need some outlets to run the workshop. That wire will end up either in its own grid tied breaker box or goes straight to the inverter. Depends on outcome of tomorrow's debate.
When we lived in the Tiny house, we used solar for lights and water (cold and hot), radio and some small appliances (clock, chargers...). On sunny days it was enough. My guess is, that you might not use so much electricity as we did, since it was four of us and Tara and kids are not exactly people, who would think about saving power.
My take on the whole thing is to start with what you have and make necessary steps to have it ready for upgrade. Then we wait if it works....

Subject: Your electric idea
Hi Tomas,
I spoke with Tom after I got back tonight, and he seemed to think that you were planning to hook the 50 amp cable up to the little skinny wire? Something about how they were both sitting in that junction box together. I think he agrees with your plan to add a breaker as the cable comes into the house and split it up from there. That's what I told him you were doing, anyway.
I thought that the purpose of the spit was so the grid could continue to charge the batteries when there was not enough solar power? Assuming that it did so when the fridge and washer weren't demanding energy. But both Oliver and Tom seemed to think that this wasn't possible and that the arrangement you had before wasn't likely to be replicated,
Anyway, I'll be there in the morning tomorrow. I can run over to the Home Depot in Littleton and pick up the breakers we need, assuming that we plan to go with your idea. Brad is also available to talk to us in the morning.
Thanks for all your work. This electric stuff is hard, but it's because we're trying to do things that mostly haven't been done before. Always harder than doing it the same old way.
Cheers, Gwen
