How to choose solar energy companies in Tucson

Tucson skyline

Arizona ranks 3rd in the U.S. in solar power use, and half a million homes in the state use solar energy to power their homes. Tucson is one of the leaders in solar power and has the second largest cluster of solar companies, behind only Phoenix.

Solar power systems are becoming more affordable, and some companies offer systems for no money down. There are multiple ways to finance a residential solar power system, including:

  • Lease: Some companies lease solar energy systems to Tucson residents. While the lease costs will prevent you from receiving the same savings as owning a system, leasing can be a good way to get a solar energy system for the minimum upfront cost.
  • Power purchase agreement (PPA): Under a PPA, a solar energy developer will install a solar energy system on your home and sell you the energy at a fixed rate that is usually lower than the local utility’s rate.
  • Purchase upfront: Purchasing the equipment has the highest upfront costs, but it lets you enjoy the benefits of energy savings immediately with no additional costs for the system other than regular maintenance.
  • Financing: Many companies offer financing options to purchase solar energy systems, or you can use funds from a personal loan. These plans reduce your upfront cost while also providing you with the higher savings that come from owning your system.

The cost of your solar power system will vary depending on the size of your house and how much energy you need the system to produce. Prices range from $7,000 for a small system up to $28,000 or more for larger systems, and the average cost for a system in Tucson is around $15,000. Most solar energy companies offer free estimates.

Besides the immediate savings you’ll see on your utility bills, you can also help offset the costs of installing a solar power system with the current federal renewable energy credit. Arizona also offers state incentives to encourage residents to install solar power systems.

Installing solar energy systems in Tucson

While solar panels will fit easily on the roofs of many Tucson homes, other options are available if necessary. Panels can also be installed in your yard, and some communities choose to share panels. Many companies also offer battery options that will let you store solar energy to be used at night and will need to be installed inside your home. Talk with your solar energy company to decide what options work best for you.

Most residential solar energy installations in Tucson use polycrystalline or monocrystalline solar panels. Which one you use may depend on your location, solar energy system provider and budget.

Polycrystalline vs. monocrystalline panels

Polycrystalline Monocrystalline
Cost Low High
Efficiency 13% to 16% average 21.5% maximum
Space required Requires more space due to lower efficiency Requires less space due to better efficiency
Material Silicon Silicon
Performance Not good for low light and heat Good for low light

Repairing and maintaining solar power systems in Tucson

Whether you purchase or lease your solar power system, your chosen provider will install the panels and other equipment. If you lease your equipment or install it under a PPA, the provider will maintain and repair the equipment. If you purchase the equipment, you’re responsible for repairs and maintenance.

Most companies in Tucson offer warranties on their products, so be sure to compare what’s covered and for how long when purchasing a system. Solar panels are durable and usually do not require much maintenance besides cleaning every few months to make sure they’re operating at peak efficiency. Your solar system company may provide maintenance service if you prefer to have this done professionally, however.

Your homeowners insurance or home warranty may cover your solar energy system. Ask your insurance or warranty provider if your plans extend to a solar energy system and under what conditions.
