As demand for residential solar panels in Phoenix continues to grow, more homeowners are shopping around for the best deal. But not all solar quotes are created equal — and the lowest price doesn't always mean the best value.

If you’ve received multiple proposals, how do you know which one offers the right balance of price, performance, and long-term reliability?

Here’s a step-by-step guide to comparing solar quotes in Arizona so you can make a confident and informed decision.

1. Compare System Size and Projected Output — Not Just Price

Two quotes might have very different price tags, but that doesn't mean one is a better deal. What matters is cost per watt and how much electricity each system is expected to produce over time.

Ask:

• What is the total system size (in kilowatts)?

• How much annual energy production (in kWh) is projected?

• What is the estimated cost per watt?

A slightly more expensive system that produces significantly more electricity may deliver better long-term savings.

2. Look at Panel Quality and Efficiency

Not all solar panels are the same. High-efficiency panels may cost more upfront, but they generate more power in less space and degrade more slowly over time — ideal for Phoenix’s long-term sun exposure.

Consider:

• Panel brand (SunPower, REC, Q CELLS, etc.)

• Panel efficiency rating (typically 19–22%)

• Warranty terms (look for 25-year product and performance warranties)

Low-end panels may save you money now but cost more in lost production over time.

3. Understand the Inverter Technology

Inverters are a critical component of any solar system. They convert DC power from your panels into AC power for your home.

Ask:

• Does the quote include string inverters, microinverters, or hybrid inverters?

• What brand is used (Enphase, SolarEdge, etc.)?

• Are inverters covered by a separate warranty?

Microinverters (such as Enphase) are great for roofs with shading or complex layouts, as they allow each panel to operate independently.

4. Evaluate the Installer’s Experience and Reputation

The best equipment won’t help if the installation is poor. Workmanship affects system performance, roof protection, and long-term reliability.

Check:

• Is the company licensed and bonded in Arizona?

• How long have they been installing solar in the Phoenix area?

• Do they specialize in tile roof solar installation if applicable?

• Are they using subcontractors or in-house crews?

• What do local customers say in reviews?

An experienced, local company that knows Arizona’s climate, utilities, and permitting process will deliver smoother results and better post-installation support.

5. Ask About Incentive Handling and Financing

Solar savings depend heavily on accessing available credits and rebates. A good installer will guide you through the process and offer transparent financing options.

Ask:

• Will the installer help you file for the Federal Solar Tax Credit and the Arizona Solar Tax Credit?

• Are there $0-down financing options?

• Is the quote based on a loan, lease, or cash payment?

• Are utility application and permits included?

At Phoenix Valley Solar, we handle all paperwork, permitting, and utility interconnection — so your system qualifies for maximum solar incentives in Arizona.

6. Look Beyond the Price Tag

The “cheapest” quote might cut corners — with lower-quality equipment, minimal warranties, or poor support after installation.

The “best” quote delivers:

• Strong long-term savings

• Proven equipment

• Reliable installation

• Full warranty support

• Local service when you need it

Focus on value, not just price.
