Comment on Solar Panel Questions

  Glad to help. I’ve been investigating my own solar install, so have been digging into the specifics a lot.

  Note that the above are the “best case” numbers. Panels can put out less power for lots of reasons. They tend to lose a little bit of efficiency when they get older. Think 1%/year, but that’s just a rule of thumb. Being dirty can affect them, cloud cover, angle and position, and hilariously counterintuitively, if they get too much sun. Solar panels get less efficient the hotter they are, so an especially sunny day will lower the power output.

  Leads to some complex math to optimize, but honestly its power that just hits your house for free. That’s a fine thing in any circumstance.
