Lowest $/W for SunPower system

Why would anyone ever pair Sunpower with Enphase? The voltage isn't right... Enphase takes 48 V max, and the lowest SP panel I've seen has a 50.9 Voc. Even if you ignored that, clipping would be something nasty on the 327+ W panels of the last two generations. Anyone selling Sunpower+Enphase is trying to steal your money. -

I can get you sun power/enphase combo for less than $3.5/w but apparently I'm not allowed to give out my company name on an open source solar forum infested with advertisements for solar city
Look me up or feel free to email meLeave a comment:

Because of high voltage in cold climates, SunPower / Enphase is a combo that won't work in where temperatures can fall below -20C in winter. Instead, I went with ABB 0.25 micros that, with a little shopping around, ended up costing a lot less than the M250's.
If a deal can be found on discontinued SunPower gear; I'd go for it. FWIW, I took a chance on 42 used SunPower E18 all-black panels on Craigslist at $0.44/w. They work great and look awesome.Leave a comment:

In Southern California I give my clients with shingle roofs around $3.4/w for sun power panels and enphase 250
Of course, there other contions that change
that number slightly up or down, electric panel upgrades, roof conditions and such...Leave a comment:

Even at $3.35 per watt this puts my 8.5 kw system yielding a cost of 28475 , now take off the federal 30% rebate that gives a $20000 cost. The interest (at 3%) on $20000 would be $600, yielding a savings of about $600 per year, giving a payback period of 33 years, 8 years beyond the best warranty
I was quoted a cost of $16,000 for my 8.5kw system, I am now wondering how this is possible.....Leave a comment:

I have seen prices like that.
But have always been for end of life panels ( discontinued panels not used)Leave a comment:
