Hi!
I'm back 2 years later on this forum, I got great help last time and realized I was clearly not ready for solar then.. and luckily I didn't go with Sungevity who is no more..!
I've done my homework since (enough to be dangerous!) and reactivated the solar project now that I've got a real EV.
I also did all the math for estimating my usage looking at the last 2 years worth of data and adding the new EV at 12k mi/year, 4mi / kWh (3k kWh extra yearly).
So my estimated annual usage falls at around 7,400 kWh.
I've done lots of quotes this time (12+), and after "getting educated" with some of those vendors I've narrowed it down to 2 competitive offers.
Some had suggested reverse tilt on the North side near the ridge at the top, but the added cost and number of penetrations in my roof dissuaded me.
Adding more panels on the North for the same price as reverse tilt was also not worth it, and the last thing I want to do is to overproduce.
My utility is unfortunately SDG&E and a bit worried about their minimum bill proposal but that's a topic for later..
I'm on EV-TOU-2 schedule and keeping the on-peak hours (4-9pm) below 3kWh total every day so far.
My EV use (those 3k kWh) will be 100% in super off peak.
The system I'm building is 14 panels of Panasonic 330W (VBHN330SA16), and doing a larger inverter for future expansion (SolarEdge SE7600H HD-Wave Inverter).
All the panels will most likely fit at the same orientation:
Roof Details
Roof Pitch 23deg
Roof Azimuth 152deg
PVWatts estimate my production at about 7,500 kWh / yearly.
Here are the top 2 quotes.
Please note they both include a main service panel upgrade to 200Amps (currently at 125Amps) instead of doing the SDG&E Renewable meter adapter (which is $1326).
LA Solar Group - 251 5-star yelp reviews
14,553 before tax rebate
(- 2000 for panel upgrade) = $2.7/W
Semper Solaris - Less reviews in OC but 200+ in San Diego. My neighbor has used them hence getting some referral discounting
(waiting for them to match the LA solar quote)
Attached is a picture of my roof with a rough proposal of the layout.
It seems that the rules for setback have changed recently, allowing for 18in clearance at the top ridge.
Really looking for feedback, anything I'm missing, Thanks!!
