Palmetto Solar Details

Palmetto Solar tops our list of top solar companies in Arizona due to its focus on customer service. In addition to full-service installation and post-installation services, the company provides tools like an online calculator to estimate savings on electricity bills. Customer support is available via phone and email and on its website. 

Palmetto’s standout offering is its Peace of Mind Protection Plan. Offered in addition to its standard 25-year warranty for an additional $12 per month ($144 annually), Palmetto’s Peace of Mind plan covers labor for repairs or replacements. The plan also includes guaranteed service timelines and discounts on solar panel cleaning, panel removal and reinstallation, and pest abatement. In total, the Peace of Mind plan offers $1,975 in discounts and savings, according to the company’s website. 

Like most solar companies, Palmetto Solar does not provide online estimates since pricing depends on each home’s layout and exposure to sunlight. However, Palmetto will provide you with a personalized solar panel installation quote following an in-person or virtual consultation to review your home. 

Palmetto Solar customers can purchase solar panels outright or through a loan, which allows you to own your system with no money down* through monthly payments. The company also offers leases and Power Purchase Agreements (PPAs). While leases and PPAs both constitute third-party ownership, lease payments are set at the same monthly rate. PPA payments, by contrast, vary each month depending on your energy usage, similar to an electricity bill.

Vivint Solar Details

Vivint Solar’s wide range of products and services allows customers to create a customized solar system that fits their home, budget, and energy needs. Vivint uses only Tier 1 panels and partners primarily with LG to offer LG Chem. This compact battery storage device is installed in your garage or a covered area to provide energy at night or during an outage.  

Tier 1 solar panels, as defined by Bloomberg New Energy Finance Corporation’s rating system, are those made by manufacturers in business for at least five years that invest in marketing their brand and are highly regarded in the industry. While designated as top-of-the-line within the solar industry, Tier 1 panels can also be significantly more expensive than Tier 2 panels, many of which meet most Tier 1 standards.

Although it carries LG products, Vivint can often provide products outside its standard offerings, such as Tesla panels and Powerwall batteries, when requested by customers. Additionally, Sunrun acquired Vivint Solar in 2020, effectively broadening Vivint’s products, services, and reach.

Sunrun

Score: 95 out of 100

Capturing more than 14% of the residential solar system market, Sunrun is currently the largest solar provider in the United States. Sunrun primarily carries LG products but can accommodate customer requests for products from major competitor brands such as Tesla. 

Pros and Cons

✔ Protects Brightsave products with coverage for theft or damage

​​✔ Partners with LG to provide customers with a solar battery option

✔ ​​Offers online chat support

✘  Doesn’t offer a power warranty to customers who lease or purchase their panels 

✘  Numerous online customer reviews cite aggressive sales tactics

Sunrun Details

Sunrun is our pick for financing options since it was one of the first solar companies to offer a leasing program that made solar power more accessible to homeowners. In addition to a monthly payment lease option similar to other solar panel companies, the company has a 25-year prepaid lease. The prepaid lease comes with free monitoring and maintenance over the life of the contract. 

Customers also can purchase their solar panels with cash or through in-house financing at no money down for those who qualify. 

Sunrun has an optional “bumper-to-bumper” system warranty that covers 100% of equipment replacement and system repair costs for ten years. The warranty also includes proactive monitoring and a comprehensive insurance policy on your panels.

While you can get an instant online quote through Sunrun, keep in mind that these are general estimates. Sunrun cannot give you an accurate cost until completing an in-person or virtual home consultation.

Pros and Cons

Blue Raven Solar Details

The company stands out for its BluePower Plus+ purchasing plan, which includes 18 months of free solar power, thus speeding up the return on investment. In addition to 18 months of deferred payments, BluePower Plus+ includes free upfront design work, permitting, and installation. 

Through its SmartStart financing, Blue Raven extends the usual 18-month period of promotional loan over five years and sends monthly reimbursement checks to offset the difference, so customers pay out the same amount for 42 months.

Blue Raven Solar products come with a 25-year manufacturer warranty, a 10-year workmanship warranty, and a two-year power production guarantee. Power production guarantees ensure a system will continue to generate close to 100% of its energy capabilities for the length of the guarantee period. 

The company can generate a basic online quote using your Arizona address, average monthly electricity costs, and credit score. However, you will only receive a detailed estimate following a home inspection.

Trinity promotes its battery as quiet and low-maintenance.

The company has a mobile app that allows customers to track energy use by month, day, or hour and check their system’s performance. 

Each Trinity residential solar system comes with a 25-year warranty that covers the panels, inverter, and other related equipment. Trinity also provides a five-year workmanship warranty on the solar installation that covers labor costs. 

The company provides no-money-down financing* for solar panel installations and a monthly solar loan plan. Customers can also opt to pay for their solar system outright.

Our Conclusion

We have picked Palmetto Solar as a top choice for Arizona homeowners because of its focus on customer service and creating a seamless installation experience. However, we recommend requesting and reviewing quotes from at least three different solar companies before making a final decision. 

You should also take a close look at your monthly electricity bill and compare it against your state’s average cost of power. If you have consistently high payments or the cost of electricity is more expensive than in other areas, solar panels may be a good solution. If you have relatively low bills or can find ways to cut down electricity usage significantly, you may not see enough cost savings to justify the expense of installing a home solar system. We recommend getting at least three quotes to determine the best rates for your home.
