Comment on Leased Solar Systems Are Failing Across America

  Technically, they lose about 20% of their generation capacity within a few hours of first exposing them to sunlight. It's one of those weird quirks that researchers have been trying to solve for decades.

  Also, they tend to lose the rest of their generation capacity over decades, not millennia. The industry standard is for a panel to be able to produce 80% of installed capacity after 25 years.

    Jesus. The initial transient used to be about 3%, but now is under 1% for most product being sold. It was never near 20%.

    But that doesn’t stop idiots from saying “we have optimizers” and installing them in the shade or facing north and acting surprised when they underperform.

      Note to antipodes: you do want to install yours north

    How much capacity would you say the Milky Way has left then?

      About 4.5 billion years.

        Just 4 billion? Pfft! I’ll stick with fossil fuels, thanks!

        They also predict a 12% chance that the Solar System will be ejected from the new galaxy sometime during the collision. Such an event would have no adverse effect on the system and the chances of any sort of disturbance to the Sun or planets themselves may be remote.

        “We” may be able to explore the cosmos without leaving home.

    A team at NREL found evidence for the cause of this a couple years ago. It’s something to do with interaction between the boron and the oxygen content within the silicon cells. If it holds up, hopefully we’re on the road lessening the degradation over time.

      Some panels are around 90% at 40 years now.

  "meanwhile, the amount of energy guaranteed each year lessened as the panels aged. "
  So it is pretty much this except the companies whilst leasing were not maintaining nor do you get to trade in.
