Installer notes

The thinking behind this design.

Troon tile job - tile-lift crew pulled 96 S-tiles, installed Quick Mount QBolt flashings on every penetration, re-set tiles with new butyl. Powerwall mounted in garage on west wall (vendor-spec 50°F–86°F preferred). Customer self-consumes 78% of production through the 4–7pm APS peak window with Powerwall load-shifting; remaining export at APS Export Rate Rider rate. SRP-equivalent payback math here: 6.2 years cash, but customer financed via $0-down GoodLeap loan at 7.99% / 25 years and was cashflow-positive month one ($168/mo loan replaces $312/mo APS bill).

★★★★★
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.

★★★★★
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.
