If you want to employ their services, be prepared to potentially wait in line for a while.

On top of 25-year manufacturer warranties for their solar modules and a 10-year workmanship warranty, Net Zero Solar is also confident enough to offer a 5-year system performance guarantee. This means that if your installed system falls short of producing the predicted level of electricity, Net Zero will compensate you for the difference at retail rates.

Elevation Solar

Elevation Solar is an Arizona-based solar company who also operates in many nearby states. They offer a quick online review process for potential customers: simply upload your utility bill to receive a customized quote from them!


Elevation Solar has their headquarters in Chandler, Arizona, along with offices in Tucson and the states of Texas and Nevada. Their extremely wide service range, though, extends across multiple state lines to include the entirety of Arizona, California, Florida, Nevada, Texas, Utah, North Carolina and South Carolina.

Their reputation on the BBB is less than stellar however, despite being BBB accredited and rated A+: they only have a 3.69 customer rating and 42 complaints.


Only 9 complaints have been resolved so far, and many customers complain about issues with wiring and poor customer support. Elevation Solar’s BBB reviews do come from its customers across all eight US states though, which might explain the difference in rating between its BBB profile and its Arizona Google listing.

Final Verdict

Of course, no solar company is perfect. But out of the eight installers compared above, our top choice is Net Zero Solar. Their amazing online customer reviews stand out at first glance: After 12 years in business, they currently do not have a single negative review across a combined 183 ratings on Google, Facebook and Solar Reviews. Most importantly, they have won praise for refusing to over-sell to their customers, which is a common complaint for many solar companies. They make sure that their customer pays for only exactly what they need, and nothing more.


They also offer a unique warranty that none of the other solar companies on this list have: a five-year system performance guarantee. If your installed system should produce less electricity than initially quoted to you (another common complaint for other solar companies), Net Zero is willing to compensate you for the difference, ensuring that you don’t lose out because of their error. Their glowing reviews are clearly no mistake: this is one solar company which knows how to do right by their customers.

Solar Energy in Tucson, Arizona

Tucson is in contention for one of the best locations for solar power in the United States. Arizona’s fierce desert sun shines upon Tucson for 284 days a year, putting the city up there with the sunniest cities in the country. Overall, Arizona state has the second highest solar potential out of all US states, and ranks fourth when it comes to total installed solar capacity. Arizona’s former governor, Janet Napolitano, has even referred to the state’s incredible solar potential as capable of turning it into “the Persian Gulf of Solar Energy”.

But while Arizona has many notable utility-scale solar projects, including what used to be the world’s largest solar power farm, its residential solar installations have been lagging behind. It only ranks ninth in the US for residential solar capacity despite its massive solar potential. Clearly, the state still has a long road to go when it comes to promoting solar adoption.

Laws & Regulations

Arizona state laws have long pushed for renewable energy adoption. Back in 2006, they adopted the Renewable Energy Standard and Tariff (REST) which required the state’s public utilities to generate at least 15% of their power from renewable sources by 2025.

Renewable energy policies have recently faced several set-backs in the state, though. New and more aggressive clean energy rules, requiring public utilities to source 100% of their electricity from renewable sources by 2050, were rejected in a surprise decision by the state’s regulators in 2021. Instead, they opted for a plan which would require utilities to source 100% renewable energy only by 2070. This puts Arizona’s clean energy policies behind other states like California, New York and Washington, which all require their public utilities to exclusively use renewable energy by 2040 or 2045.

Tucson itself has also run into recent issues with solar power adoption. Even though many homeowners in the city are eager to install solar for their homes, some customers of Tucson Electric Power (TEP) have reported having their applications for grid-tied solar power turned down. This is a result of new regulations set by the Arizona Corporation Commission, which has limited the total solar capacity that can connect to the local grid in each neighborhood. TEP has said that the new rules are necessary in order to protect the grid from damage, but it has left many Tucson homeowners frustrated.

Tax Credits and Incentives

Arizona state has one of the most generous incentive packages for installing solar. State residents are eligible for the Personal Tax Credit incentive, which pays out an personal income tax credit equal to 25% of the cost of their new solar installation, capped at $1,000. Other types of renewable energy installation, such as wind or solar thermal systems, are eligible for this scheme as well. The state also has a property tax exemption for home solar installations: renewable energy systems are valued at $0 for tax purposes. This means that while installing solar on your rooftop increases your home value, the property taxes you pay would stay the same.

On top of these state incentives, you can also take advantage of the Solar Investment Tax Credit (ITC). This federal scheme gives new solar installers a federal tax credit equal to 26% of the cost of solar installation. Unlike the earlier Personal Tax Credit scheme, there is no cap to the credit that can be provided, though the program is set to phase out after 2023 for residential solar installations.

Net Metering

Net metering schemes were discontinued for the whole of Arizona in 2016, in lieu of a new net billing policy. Previously, net metering meant that Arizona utilities paid retail rates for the excess electricity generated by a residential solar installation – this payment offsets your monthly electricity bill, and if you sold back more electricity to the grid than what you used, the utility would have to compensate you for this extra electricity at the end of your annual billing cycle. The new net billing approach keeps this same billing structure, but lowers the rate that utilities pay for your electricity. Instead of receiving a retail rate, the utility now only pays you a lower “avoided cost” rate for your solar power. This avoided cost rate is calculated based on how much it would have cost the utility to generate the electricity they bought from you, rather than how much it charges customers for this same electricity.

The main Tucson electric utility, Tucson Electric Power (TEP), currently pays customers 8.68/cents per kWh for renewable energy sold back to the grid. This rate is slated for a further drop to 7.81/cents per kWh in October 2021. Both figures are lower than TEP’s retail rate of 10.5 to 13.1 cents per kWh for residential customers.


While Arizona does not have a specific solar license regulating solar installers, Arizona solar companies require a CR-11 Electrical License, which authorizes them to perform electrical work on both commercial and residential properties. Solar heating systems do have their own set of licenses however, including specific Solar Water Heating, Solar Space Heating and Solar Pool Heating licenses. These types of solar thermal systems are different from the electricity-generating PV installations we discuss in this article, though some of the solar companies we cover above also offer these services.

Outside of these mandatory state licenses, the North American Board of Certified Energy Practitioners, or NABCEP, also provides certification for solar installation professionals. These certifications are sought after in the industry, and require applicants to pass a rigorous examination or provide proof of real job experience as a solar installation technician. Many reputable solar companies, including those on our list above, count at least a few NABCEP-certified employees among their team.


Despite recent changes to Arizona’s net metering payouts and new limits on solar power in Tucson, generous state and federal incentives for solar power still make a solar installation for your Tucson home something worth looking into. There are many great solar installers in the city, some of which we covered and compared in detail above. While it’s a good idea to start by looking at our comparisons, we also encourage you to do your own research and contact the companies which interest you for a personalized quote. There’s never been a better opportunity to take advantage of Arizona’s blazing desert sunlight and save the environment at the same time!


Is Tucson suitable for Solar?

Yes, in fact it might be harder to find another place in the US more naturally suited for solar. Tucson enjoys 284 days of sunshine a year, and ranks among the sunniest cities in the US, keeping your solar panels producing electricity year-round.

Some Tucson residents have recently reported their plans for solar installation being rejected by the city’s electric utility though, due to caps on solar power for each neighborhood. In these cases, you are required to attach a storage battery to your solar installation before it can be approved, which does drive up costs. Make sure to look into this issue with your utility provider or solar company before committing to an installation!

What solar incentives are available for Tucson?

As a Tucson resident, you qualify for both a state income tax credit and a federal Solar Investment Tax Credit, respectively worth 25% and 26% of your new solar installation. There is a $1000 cap to the state tax credit, while the federal scheme is uncapped. These tax credits are not directly paid out to you though, they can only offset the state and federal income taxes which you pay.

Can a solar energy system help me save money?

Yes in general, but it does depend on how suitable your property is for solar installation. Tucson’s main electricity utility participates in a net billing scheme which pays you for the solar electricity that you generate, and these payments offset your utility bill. For a solar installation to save you money, the money you save on utility payments must be greater than the cost of installing your system, which is different for each property. Solar energy systems also have a set operational lifetime, usually around 25 years, after which the system needs to be replaced.

What licenses and certificates should a solar company have in Tucson?

Arizona state requires solar companies to hold a CR-11 Electrical license, which allows them to carry out electrical work on residential and commercial properties. This is separate from the state’s solar water heating and solar space heating licenses, which are required for contractors looking to install solar thermal systems. If you’re looking for a contractor to install an electricity-generating solar PV installation, like the ones discussed in this article, an electrical license is all that’s required.

However, it can also be a good idea to check that the solar company you hire employs NABCEP-certified PV Installation Professionals. This optional certification is awarded to individual technicians after completing a rigorous examination or providing proof of long-term experience as a solar installer.
