Yes. A 400w watt panel is 250$. When you account for labor and cost of all. The parts for a moving panel that can withstand high wind speeds…Placing more fixed

> A 400w watt panel is 250$. Wait, panels are that cheap? Could you point me to a good place to buy them?

I don't know what, where, or how many you want, but these are by the pallet (~30ea) and about $6500. You can get much cheaper with used ones. You get conservatively ~3hr of effective peak power per day (so a 400W panel will give you 1200Wh). You also need a DC converter for these to charge a battery or go to AC. Of course you'll want to mount them at the correct angle with a good view of the sun.

  You generally have to buy them by the pallet-load, FOB ("free on board") at the source, which means you arrange shipping. Home Depot marks up 4x for local purchase. But used panels, at 80% rated output, are even cheaper, as low as $150. A few of those will fail, so you keep spares. They are often repairable in a few minutes if you are not afraid of a soldering iron, e.g. replace a diode or MOSFET. Any roofer will put in mounting brackets, and almost any electrician is happy to put in the panel.

    Decent vendors such as sunelec.con will easily quote you a price for a one pallet load LTL freight shipment of a pallet of, say, 22 panels. Not like you have to arrange your own freight and often they get a better price because of they great monthly spend with the major us48 state LTL freight carriers. Be sure to specify if you need liftgate service at the destination or not, because that will affect cost, otherwise by default a pallet by LTL freight will need a loading dock to receive.

  $3 per watt, installed on your roof is typical these days: https://www.remodelingcosts.org/solar-panel-costs-increase-seia-march-2022-report/ https://www.remodelingcosts.org/solar-panel-costs-increase-s... That includes labor, mounting hardware, inverters and grid tie in. It also assumes high efficiency panels. Watch out before buying older technology (lower efficiency) panels. Some have significant efficiency losses per degree Celsius increase in temperature.

    I paid $1.47 per watt for 3200 watts last summer but that's in Mexico.

    I bought 42 Sunpower X21-335 panels used for about $4700 shipped to my door a few years ago and couldn't be happier. As far as I could tell they weren't actually ever unboxed.

      For the numerically challenged, that is $4700/42 = $112 each. $112/335W = $0.33 per watt. Installed, well under $1.

        Yeah, the whole system has been fantastic. I'm so glad I did it. DIYing it was also fun.

    > $3 per watt, installed on your roof is typical these days Which is why I was so fascinated by someone saying that you could get panels at 250USD/400W=0.625USD/W; I suppose it's possible that all the other stuff (electrician, mounting, inverters) is the difference, but a factor of 5? That feels like an chance to do something hacky and come out way ahead (like, say, DIYing a panel to run your computers, thus cutting out rewiring the house and needing an inverter).

In Europe they are even cheaper as we don't have high tariffs on Chinese panels. I can buy a 350W panel for €150 including taxes, or €100 if I go to the equivalent of Craigslist and don't care about warranties.
