American solar installer companies do seem to charge way more than European or British ones. I got 3.9kW installed almost ten years ago for just £5500, including all the paperwork for feed-in-tariffs. It has long since paid for itself just in subsidy, let alone actual consumption.

We had 18x510w panels (9.2kw), 2xZappi chargers, PW3 & Eddi (to heat hotwater) installed ~5 weeks ago. Total cost was £17k (inc. scaffolding, cert, etc), in the SE England, with a small recommended contractor. The UK solar market is full of rogues as well, charging massive sums, many for pretty questionable systems. We had 5 quotes to get there, 3 of which were crazy in one way or another.

We hit our first MW/h of power today. In England. In April. Total electricity bill for the last 6 weeks is about £30, and that includes our driving (previously £150 to £200 p/m) and most of our hot water. If you have the property for it and available investment, the ongoing savings are instant and obvious! My instant regret was not having done it sooner. Driving around on your own sunshine does feel magical as well!

In general, contractor overhead in America is obscene, compared to Europe. We have a lot of regularly capture working to keep it that way, too.

  • DIY is viable if you're a bit nutters (like me).

    I just paid ~$35k (pre-now-expired-tax-break) to install a grid-tied 25kw ground mount system. I DIY'd everything except the connection between the array and the grid, which I paid an electrician to do, and the trenching which I paid my buddy with a mini-excavator to do.

    It was a bit of a PITA, but mostly because I didn't finally make up my mind to do it until October and had to have it constructed by Dec 31st to take advantage of the expiring tax credit. If I'd given myself 6 months, it would have still been a big project, but way less stressful.

    My neighbor's paid the same price to a contractor for a 11kw system.

    Even at 46°N, and with relatively cheap electricity, my system should pay for itself in 6-8 years.

    • Do you have a blog or a writeup about this?

      What would have been the cost if it was not DIY'd? Is this doable only in a rural/semi-urban settings?

    • In EU it would be some $3k for inverter, $5k for panels, another $5k for cables, connectors and mounting and that's it if you DIY everything. Prices with VAT included.

    • Being an honorary or actual redneck in an exurban American setting will be the sweet spot for this. Your neighbor's rusting Bobcat is not useless after all. You have the space for ground mounting. I toyed with a rooftop solar DIY project with an electrician handling the AC side, but in my urban context PG&E wanted a six-figure fee for a subterranean transformer upgrade. In 2024 the state regulator established rules that PG&E can't charge for that kind of service upgrade so maybe I should start considering it again.

  • I am counting on physical, semi technical contract work to pay once SWE opportunities shrink to the point where it’s not worth it anymore.

    Now is the time to get handy if not already. Robotics /physical automation will lag info by a good stretch.

  • We looked at trying to get some mini-split heat pumps for my mom's place & were getting quotes $30k figures for two modest units (it's a tiny well insulated house). I don't know what the frak is wrong with this nation; this is so fantastically worrying.

    • Home HVAC is the most obvious current regulatory caused scam in the US. Virginia just added an 'easier' license that 'only' requires two years of experience to receive (and 160 hours of formal training, but that's not the bad part obviously).

      Something like a minisplit though can literally be DIYed in under a day. With experience, a DIYer can do it in a couple hours. They're literally designed to be easily installed as a complete system. Even in Japan you can get one installed for under a grand (including the unit). In China it's obviously even cheaper.

      Obviously HVAC companies don't want it to be easier to get a license, they make boatloads on entire home systems and maintenace. Being able to just replace a broken unit for $600 would kill their entire business model.

      Electrical is a similar scam, though for some reason if you get enough quotes you can usually find one that isn't charging the equivalent of $1k/hr in labor like getting a mini-split from an HVAC company tends to be.

    • HVAC is wildly variable, even more so than other trades in my experience. Get several quotes, there will be five digit differences between the top and bottom.

One of the reasons for this is that in many parts of the US, solar has sadly been market segmented as a luxury product, just like other high efficiency products like heat pumps or EVs.

This is enabled by both the prevailing cultural attitudes about efficiency and renewables as indulgences for the better off, and industries that are happy to keep captive high margin markets of those customers, i.e. the continued lack of a US produced low-cost EV.

The American cult of individualism is also at play, wherein collective solutions are shunned vs private ones, which is why renewables and storage are so popular among off grid libertarian types.
