How Old is "Too Old"

[ButchDeal]

Thanks for that reply. I total beleive everything I have seen here on the forum and what you said in this reply. I guess the sticking point for me was the Sun Power seemed to have moved to micro-inverters built into the new panels, and the older panels rely on a seperate inverter +/- Sun Edge optimizer.
I think the salesman's main point was that having pannels without the microinverters is obsolete. Seems like the more unbiased answer is that those panels are still perfectly good.

SolarEdge not Sun Edge.

Your salesman is trying to sell what he has. He is trying to convince you that micros are the way of the future when they clearly are not.
Also the idea that one set of PV modules is OLDER tech than the other also seems strange. I wouldn't give this sales person any credit other than being very full of BS.
