Installer notes

The thinking behind this design.

Power Ranch 4,100 sq ft two-story with pool, two EVs, and a heat-pump pool heater - total annual usage was 24,800 kWh and we sized for ~88% offset to keep within the SRP demand-rate sweet spot. Two Enphase 5P batteries chosen over Powerwall here because the customer already had an existing 6.8 kW Enphase system from a 2019 install we were adding to - IQ8H microinverters integrate natively, and the 5P stacks let us drop one battery now and add a third in a year if the EV count goes from two to three. Demand-shaving through the 4–7pm SRP peak cut peak kW from 11.2 to 3.4, which alone saved $880/yr on the bill.

Real customers. Real receipts.

5-star average across 480+ Google reviews. We’re happy to share full monthly-production data on any nearby install - or just drive you past the rooftop with our yard sign on it.

★★★★★
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.
