    Look at the date on the article you linked. It was published on July 7th.

    When solar panels are seeing 15 hours of high-angle summer daylight and clear skies, generation should be considerably overcapacity.

    Come back to me when you can write that same overcapacity article in November, when your panels are struggling with 9-hours of low-angle overcast.

    When you have sufficient solar capacity to meet winter demand, you’ll have 200% - 400% of demand in summer. That is simply the nature of solar production outside of the tropics.

      Of course, it depends on the conditions. But any (temporary) overcapacity becomes a problem for people with solar panels when they expect to pay off the cost of the panels not just with a reduction in drawing power from the grid but also with credits from sending power to the grid.

      However, there are problems, with some grid operators even charging customers for energy sent to the grid during peak times, such as in NL: https://innovationorigins.com/en/solar-feed-in-tariffs-climb-18-in-six-months/

      Solar without storage is less ideal than most people think.

        Yes I literally have to pay when I produce more than I use, like every day in April.

        I looked into batteries, but they cost 10 times my annual power bill, and of course they wouldn’t replace all electricity, so would take like 20 years to be cost neutral.

        I’m considering buying a high power laser and turning it on to consume extra electricity. I’d rather send photons back into space than pay the power delivery company.

          Try bitcoin.

          The ROI on bitcoin is substantially greater than that of a high power laser aimed into space.

        Seasonal variation.

        If you are doing solar right, you will have surplus power from it 9 months out of the year. The solution to making it profitable is not storage. It’s finding customers who can use that excess power, but won’t increase winter demand.

          The ultimate solution is likely the creation of small scale localized carbon capture that exists to manage summer overcapacity.

          The current biggest issue with carbon capture is that it’s less efficient than not burning fossil fuels in the first place

            Desalination, fischer-tropsch synfuel production, hydrogen electrolysis. Even if we can’t find anything productive to do with the power, there are plenty of useless, nonproductive ways to monetize excess power: AI and Crypto, for example.

            Overcapacity is not an actual problem.
