Renvu and CED Greentech are both convenient in your area. I bought my system components from CED about ten miles from me in Santa Rosa. Considering some more panels in the next six months.
@Ampster thank for pointing out
CED Greentech, who's Web site provides an incredible choice of PVs.
I contacted the San Francisco Bay Area location and I had a very good talk over the phone.
However, when I went there they were not able to find any 72 cells.
They only carry 60 cells, and mostly the Hanwha Q-Cells type,
and mentioned that the 72 cells were used for industrial applications.
They also mentioned that they would not sell to me any electrical hardware devices,
telling me that those were very complex (meaning risky..) to use and they could not provide any help.
But instead, I could get from them any mounting hardware that I might need.
This tool indeed allows you to determine the
hardware needed to design your roof or ground mounted solar system,
using ASCE 7-16 (American Society of Civil Engineers)
wind design code or recommendations
While everything looks so simple as an armchair developer,
I realize that becoming a hobbyist solar installer is more challenging than expected.
I contacted some PV distributors but in general they sell palettes stack of PVs
weighing above 3,000 lbs, more than a one-ton pickup truck could carry.
Beside shipping cost (that I found similar to shipping a car by truck...),
I have also issues with shipping company no willing that
a semi truck double park in order to deliver in residential area.
I am feeling now going back to square one.
I have some space constraints so I would prefer getting efficient new PVs, even if I need buying a full stack.
I would be interested reading about any recommendation or previous experiences from getting PVs.
