  • Jinko/Maxim panels

    Has any used Maxim-optimized panels? AFAIK, only Jinko panels are available with it. Think of it as a panel with "smart diodes" that actively, and with much less voltage drop, switch around shaded cells. The only panels I've seem so far are Poly and not mono, but assuming this recent court ruling doesn't kill things, I'd expect the technology to spread to other panels.

    interesting, their marketing material, I especially like the physical size : https://www.maximintegrated.com/cont...timization.pdf The problem with all these new inventions is they lack test of time- any complication there would affect reliability and since you're stuck with them at least for 10 years to recover your money you don't want to be test site for the new inventions. OTOH if you have shading it is worth considering, Maxim produced interesting chips in the past.

      Active bypass diodes (smart FET's) have been around for a while (2012), and both microsemi & maxim know how to build hi-rel parts for rugged environments....

        They are an interesting design, but I don't see them as buying much performance at all. Seems like
        a more effective approach would be to bypass twice as many, half length cell groups. Bruce Roe

          Much less loss when they are "active" in the shade, and yes, the more bypass installed, the better the partial shade performance. But the price, my gosh, couple bucks each. Can't afford to build them in to too many panels.

            Howdy all, we have been using them for about 6 months maybe a bit more, the jury is still out as to if they do any better in shady conditions, an interesting factoid is that the 265 watt modules we have been using apparently are to be discontinued and as yet we have heard of no new and improved model, word on the street is that Trina either have or are about to have the same type of thing.

              Yeah that's part of my concern. Let's say in 3 years, one fails, and you find the mfg gave up on the technology or went out of business. I "think" the enhanced panels should play nice with non-enhanced units, but I'm not sure.

              Part of me wants to stay with truly separate components which can individually replaced in case of failure. Combining technologies is fine as long as the enhanced assembly will be available for the next 20 years, but we all know how squishy that is. Still thinking it over.

                On a related note, this is a pretty informative article: http://mcelectrical.com.au/blog/test...-vs-solaredge/

                  Interesting. Perhaps the paragraph near the end mentioning TV interference in 7 of 27 systems may be of some interest to your situation.
