China solar module prices keep diving

    I have almost 5kw of panels and a 5kw inverter. If solar panels get cheaper than dirt, will future 5kw inverters allow 10 kw of panels, so that the power vs time graph is a wide "plateau" instead of a thin "hill"?

    Not sure if it's a comparable metric, but it seems to largely follow the long term time series here: https://ourworldindata.org/grapher/solar-pv-prices

    I keep seeing articles like this but install prices don't go down at all. Does news like this only apply to people building PV farms?

    So frustrating that pro-installed solar at the consumer level around here does not seem to have dropped. If anything it's gone way up.

    I am trying to figure when solar panels will have a lower LCOE than just a steam turbine alone. At that point even absolutely free fusion would have a hard time competing with solar for half the day.

    Rather sad to me that none of these price drops seem to trickle down. Hurray for more solar farms but it would nice if the price of a backpack solar panel was a dollar less than it was a decade ago.

    As a homeowner in the UK (or EU) how can I benefit from these cheap prices? What steps can I take to even just buy and hold the stock?

    Living in S.A and our decade long power crisis it is rather noticable to see solar panels now appearing on homes and office parks.

    I got 3.7Kw panels, 5Kw inverter and 10Kw battery - only our stove is not on the PV circuit - water heater is already solar based (not PV) and it has been brought some measure of sanity back to our lives.

    The worst outages was 6 hours daily.

    Should have done this a long time ago but it is now helped by banks tailoring financing packages for such installs.

    In Australia they deregulated the solar industry. Now you can get rooftop solar for around 44 cents a watt installed (66 cents Australian).

    My biggest use of electricity is my laptop and monitor.

    Any ideas on a portable solar panel that could power those during the summer? Portable because I rent and can’t fix anything down, it doesn’t have to fit in a backpack or anything like that.

    Are those numbers inflation-adjusted? That big downward spike coincides with the US inflation spike.

    where does one go to purchase said diving solar modules?
  • by mensetmanusman on 6/23/23, 7:33 PM

    China subsidized the worlds PV. That's great.

    Practically this was possible by pegging the currency which lowers the purchasing power of all their citizens.

    China's PPP should reduce in half this year. It has seen massive layoffs from every industry (average 22% decline in revenue across all industries). It has seen 50% reduction in wages, even in stable positions like government offices. It has seen unpaid wages for anywhere from a few months up to a year!!

    This is reinforced by 50% in price cuts in real estate listings in tier 1 cities, 10X increase in real estate inventory this year, and 90% physical retail decline

    Once the Chinese run out of money or they have killed off the last competition the price will increase again.

    And all of this cheap PV being produced required burning coal. We've basically outsourced this production, reduced our own coal burning, and then yell at China for increasing its carbon output.
