    About the “cheap” in the thread title: panel prices dropping 10% in Europe because of dollar weakness.

    That's been posted here elsewhere. It's talking about "quantum efficiency", where a photon can dislodge more than a single electron. Has nothing to do with thermodynamic efficiency.

    Nearly five per cent efficiency.

    If you have to use Depends with your solar cells, how sustainable is that?

    https://www.solar-outlet.nl/first-choice-320-wp-full-black-zonnepaneel.html

    320 watt, full black panel, 25 year power guarantee
    109 eur/panel incl tax
    => 90 euro per panel excl tax(in NL you can reclaim tax for solar panels)

    With 11 panels an average Dutch home is electricity-neutral.
    Less than 1000 euro in solar panels.

    Electricity savings are 700 euro per year with 20 cents/kwh. In NL we have a power netting scheme for consumers.

    Payback for the panels within 2 summers.

    Stop discussing future technology breakthrough and install panels now! Everyday without is stealing from yourself.

    You have to price in the batteries and the inverter too!

    Very long payback in some parts of the US.

    For my utility:

    Basic Charge: 2019 2020
    Up to 50 KW $41.50 $44.00 (per meter per month)
    Over 50 KW $86.50 $89.00 (per meter per month)

    Demand Charge: 2019 2020
    First 50 KW No Charge No Charge
    All KW over 50 KW $6.50 $6.50 per KW

    Usage Charge: 2019 2020
    First 10,000 kWh 9.96¢ 10.21¢ per kWh
    Next 50,000 kWh 7.14¢ 7.32¢ per kWh
    All kWh over 60,000 kWh 5.44¢ 5.58¢ per kW

    Most of our power comes from Bonneville hydro/wind. "50 KW' refers to single-phase 200A/240V service.

    Interestingly, the rates for EV charging stations are thus:

    Three-phase, 60 hertz, at available secondary or primary voltage.

    MONTHLY RATE
    Basic Charge (includes no energy): $93.00 per month
    Demand Charge: $6.50 per KW for all KW
    Usage Charge 9.71¢ per KWH
    Minimum Charge (monthly): $93.00 per month

    Why the antithetical reaction to EVs in Oregon?

    Outside of Portland, trucks and SUVs pretty much rule. One of the local utilities has promoted EVs for decades. You might as well look for EV popularity in Oklahoma. Closest Tesla Supercharger in my area is about 20 minutes away.

    Oddly, our gas is pretty highly taxed, almost as much as in California.

    The power netting schedule means we can use the grid as a free battery as long as the total infeed to the grid does not exceed total off-take per year. No battery needed. As long as night tariff is still lower than day tariff this is Ok with the utilities I suppose.

    Inverter is 458 eur incl tax (and wifi kit).
    => 378 eur excl tax (tax is returned for private solar investment)

    So your payback time will be six month later only.
