What you say is true, but do you not think there's a way to make it so that the risk is taken out of it so you can expand the number of people who are capable of doing the install? I mean, I personally think there is, but I respect you don't feel the same. I just end up with a $10,000 bill, for the labor, to do what seems to me like a very straightforward problem to solve.

I'm 100% certain you can do it yourself.

We get Chinese solar panels here. $175 and produces 550 watt.

We then get Chinese MPTT inverters, always 2 if you run your fridge on it lol. $350 ish for one. The 5kW model. It's all one and the same.

You need a minimum of 3 panels.

So for less than $1000 you have 1.5 kWh with no storage.

Connecting the panels requires some care to ensure you stay within the parameters all GPTs know. Two pictures is all it takes. The spec label of your panel and that of your inverter.

I can't stress enough how easy it is.

The output of your inverter is 1 phase power. You can route that anywhere in your house safely since houses have.. circuits. So once the circuited is moved to the inverters grid, its seperated.. at the circuit breaker.

The scariest part was driving a screw through my roof.

It's not straightforward. If you do it wrong you kill people. Your house burns down, you burn your neighborhood down, you electrocute utility workers doing maintenance, you contribute to grid instability which is already a tight balancing act.

Can you make plug and play possible? Sure but you're just shifting the verification to a different layer and then you have to make it illegal to posses or sell any thing but the safe engineered products and you have to spend a bunch on enforcement to make sure only the safe stuff gets put in practice (not to mention replacing all the existing hardware and making it illegal to maintain)...

Modern consumer products and safety rules insulate people so much from the dangerous parts of existence that people get bothered when everything isn't like that and then want to go pet the big stripey orange and black kitty... not realizing that guardrails and safety nets aren't everywhere in existence.

And putting up those guardrails is EXPENSIVE. You want those instead of professional installation costs? Sure but the solar system you bought just got 10x as expensive as a result saving you nothing.

A house costs what... $250-500k to build these days? $10k for a major update to the build is nothing. Requiring expertise to verify dangerous things are done correctly is appropriate.
