I almost went SunPower, but if I recall correctly, they were about 20% more expensive. The installer I was working with made increasingly competitive bids with the other guys, but I don't get the sense that the company will be around in 10 years to service warranty issues.
I've got SolarEdge equipment, and expect them to be in the game long term. I preferred having an option of what equipment to go with rather than being shoehorned into a single product line.
