That guy in NH is assuming an average amount of CO2 per unit of cost. That maybe gives you an idea of how much plant food is produced when building a panel. I want an actual number in KwH. The energy that made the aluminum portion of the panel is likely the biggest energy hog but aluminum smelting is usually done with very cheap nearly carbon free electricity most of the time. The glass portions energy is usually made with very cheap natural gas.
So the unit cost per CO2 only works with maybe like an entire industrial sector, not individual products.

I already figured out how much energy it takes to make glass and aluminum.
It's pretty easy to figure out precisely how much glass they use per panel. The Aluminum is more of a smash and weigh it kind of thing. Just need to know how much they use with out smashing one of my panels.

The exact unit cost is a trade secret in some manufacturing industries. One is tires, only the top 5 or 10 people in the company know exactly what it costs to make the tires.

For the cost of a panel I could buy around 1 mega watt hours of propane or like 6 mega watt hours of bagged high grade anthracite coal.
Problem is I don't have an efficient way to turn coal or propane into electricity.

My main motivations for solar panels are to actually be able to own some of my own power generation and profit.
Like all these people who bought into solar and are looking at like 9 to 20 year pay backs, haha suckers.
I'm looking at like a 2.5 to 4 year pay back. Used panels from AZ, constructing my own racking system, laying conduit, doing every bit of wiring that I'm allowed to do my self.
I would like to keep installing solar until it's no longer profitable.
I'm thinking that means up to a 12kw single phase 240v system.
Beyond that I would have to get my 3 phase 480v transformer hooked back up. Then I would be good for like another 50kw.
