Best thing to do is get the free assessment done...and don't worry, they don't weight that much

 

System Cost
$8,604

 

ill let my crazy "friend" know

 

Hah yeah tell your "friend", if there's an earthquake THAT big... you will have BIGGER problems!!!

 

Ball park cost is ~$7 to $10 per Wp for a residential system. SunPower is the highest efficiency panel you can get commercially, which means that for a given size roof you will get the maximum output from SunPower, even though it may be a bit more expensive per Wp.
I'm actually volunteering some time on a program to implement AB811. It addresses Jeff's point of payback years and his expected tenure of ownership by allowing a homeowner to finance a solar power system and finance it through property taxes. That way, you minimize the up front cost, and if/when you move the loan payment for the system stays with the property taxes of the house. Depending on which direction your roof is facing and what kind of shade constraints you have, you effectively move your electricity bill over to your property taxes...potentially saving a couple bucks each month net/net.

 

Intresting. Apparently to get the most payback you need to upgrade meters that will measure Wp during peak/off peak. Personally I'd love to do it. Too much of an investment.
