Installer notes

The thinking behind this design.

Ocotillo 2010 tile build paired with a Tesla Wall Connector for the customer's Model Y. Solar production peaks 11am–3pm and the EV charges on a scheduled window inside that production curve - net result is ~$0 fuel cost for the EV most months. Customer is on SRP's EV TOU plan which gives a discounted overnight rate; we showed the math that keeping daytime solar self-consumption (EV charging window) was still better than exporting at the lower credit rate.

★★★★★
Three solar companies pitched us. SunWright was the only one who showed us PPA, loan, AND cash numbers side by side. Eight months in, our APS bill is $14 and we run AC at 74° all summer.

★★★★★
Crew was on time, panels were on the roof in one day, and the city inspector signed off in five days flat. They did the SRP rebate paperwork for us. Best contractor experience we’ve had in this house.
$232/moyear-one bill drop
★★★★★
We went PPA because we’re moving in five years. SunWright still treated it like our forever house - engineered for the pool load, walked us through the transfer clause, no pressure to upsell to a loan.
