Adding solar panels and switching rate plans can lower your Tucson Electric Power (TEP) electric bill

Updated: October 22, 2020

There are three ways you can reduce your TEP bill: changing your habits, switching your rate plan, and adding solar panels.

You've probably heard a lot about reducing energy consumption by doing things like switching to LED lightbulbs and adding insulation to your walls, but these fixes are relatively easy compared to the far more impactful step of making changes to your lifestyle.

The second thing you can do is switch your rate plan. TEP offers time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, and there may be other options for you as well.

Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.

How much can I reduce my Tucson Electric Power (TEP) bill by switching to a different rate plan

For some people, the savings from switching rate plans may only be a few dollars per month, but for many it can be $20-$100 per month. That's between $240 and $1,200 that you may now be paying to Tucson Electric Power (TEP) each year for no reason.

Finding out what's available to you is as simple as a phone call or email to Tucson Electric Power (TEP). Even a small savings can be worth it.

Are solar panels worth it for Tucson Electric Power (TEP) customers?

Yes, with the $1,000 Arizona tax credit, and solar property and sales tax exemptions, solar panels make a lot of sense for Tucson Electric Power customers. TEP net billing also allows you to at least get some credit on your power bill for the excess solar electricity your panels produce which you can’t use onsite. Your credits, while at a lower rate than you pay for electricity, roll over to the next month’s bill.

Does Tucson Electric Power (TEP) offer full 1 for 1 net metering credits for exported solar power

No, Tucson Electric Power (TEP) does not offer full 1 for 1 net metering. This means that when you export surplus power from your solar panels, you will be paid less by the utility than what you are charged to buy the equivalent amount of power from the grid.

The amount you are paid by the utility is known as a feed-in tariff. In the case of Tucson Electric Power (TEP), this feed-in rate is $0.09 per kWh.

What incentives, tax credits and rebates are available to TEP customers for installing solar?

The major financial incentive currently available until the end of 2020 is the 26% federal solar tax credit. The way this works is that the full cost of the system needs to be paid to the installer, and this tax credit can then be claimed back as cash when you next do your taxes.

Many states, local governments and utilities also offer incentives for homeowners who go solar. This help can take the form of state tax credits, rebates, tax breaks, SRECs or even performance-based incentives. The best part is that all of these incentives apply in addition to the federal credit.

Here is every incentive you may be eligible for as a TEP customer:
