  • What's the deal with 5W+ solar panel variants?

    I looked at a lot of spec sheets for panels when researching what to buy And they all have a range, for example 590w-620w, with 5W jumps (590, 595,600...) That's a lot of variants, and I don't get it Why not just put two options - 590W and 620W The price difference is negligible, the size is...
  • Most efficient way to 12v system from 24v?
