Common questions from Southern Arizona homeowners about solar, Tesla Powerwall, financing, and the install process.

Solar + Battery

Solar + Battery

How solar and battery storage work together for your home

forum

How does Tesla Powerwall work with my solar system?

Solar produces electricity during the day; Powerwall stores any excess. At night, during outages, or in peak-rate windows, your home draws from the battery instead of the grid.

forum

How long do solar panels and Powerwalls last?

Solar panels are warrantied 25+ years and typically perform well beyond that. Powerwall carries a 10-year warranty and is designed for daily cycling.

forum

Will solar work in extreme Arizona heat?

Yes — we install hardware specifically rated for desert temperatures, with engineering choices that maximize performance during our hottest months.

forum

What happens to my solar system at night?

Solar panels stop producing electricity after sunset. Homes may use stored battery energy, utility power, or a combination of both depending on system configuration.

forum

What if APS or TEP rates increase again?

Solar and battery storage can reduce dependence on future utility rate increases by allowing homeowners to generate and store more of their own energy.

Tesla Powerwall

Tesla Powerwall

Backup power, outage protection, and energy security

forum

What happens during a monsoon outage?

Powerwall detects the outage in milliseconds and isolates your home from the grid, continuing to power critical or whole-home loads from stored energy.

forum

Will my air conditioner run during an outage?

In many cases, yes. System design depends on the size of your air conditioner, home energy usage, and the number of Powerwalls installed. During consultation, we determine what loads can be backed up and for how long.

forum

How many Tesla Powerwalls do I need?

The number of Powerwalls depends on your home's energy usage, desired backup duration, and whether you want partial-home or whole-home backup. Most systems use one to three Powerwalls.

forum

Can I add a Tesla Powerwall later?

Yes. Many homeowners install solar first and add battery storage later. We can evaluate compatibility and future expansion options during system design.

Financing & Incentives

Financing & Incentives

Tax credits, savings, and payment options

forum

How much can I really save on my APS or TEP bill?

Savings vary based on your home's energy usage, roof layout, utility rate plan, and system size. During your consultation, we model your actual APS or TEP bill to estimate potential savings specific to your home.

forum

What incentives and financing options are currently available?

Available incentives and financing programs can change over time. During your consultation, we'll explain the current programs that may apply to your home and help you understand all available options.

forum

What financing options are available?

We offer multiple financing programs, often with $0 down. Many homeowners replace their utility bill with a lower monthly payment.

Installation Process

Installation Process

Timeline, preparation, and what to expect

forum

How long does installation take?

Most projects move from contract to activation in 6–10 weeks, depending on utility approval timelines and permitting.

forum

Do I need to replace my roof first?

Not always. We assess roof condition during design. If replacement is recommended, we coordinate timing so you only handle panels once.

forum

Will my power be shut off during installation?

Your power may be briefly interrupted when the system is connected, typically for a few hours on installation day. We schedule this with you in advance and coordinate with your utility when required.
