Thinking About Solar?

Power your home or business with clean, cost-effective energy

When it comes to solar energy, there's no place like home. Tucson averages more than 280 days of sunshine annually, making solar energy a great option for both homes and businesses. TEP offers solutions for customers to claim a share of our local clean energy resources.  We're also happy to provide information and support for customers who want private solar arrays.

A brighter future

Solar energy doesn't produce carbon emissions, so increasing its use helps mitigate climate change. Every new photovoltaic panel represents progress toward our aspirational goal of achieving net zero greenhouse gas emissions by 2050.

Spreading the sun

Solar power is a popular energy resource. We processed 5,000+ applications for new residential solar arrays in 2024.

Easy online tools

If you're looking to get a larger share of the sun, you can use our Solar Analysis tool to help you compare various solar options. You can use this tool to review the benefits and approximate the cost.

TEP has partnered with CleanPower Research to offer Solar Analysis, a service that helps you compare various solar options. Use this tool to review the benefits and approximate costs of private solar based on your rooftop's characteristics, energy use, TEP pricing plan and available tax credits and rebates. Then, see how this information compares with the benefits and costs of participating in TEP's community-solar programs.

To use the tool, you must be a residential customer with at least 12 months of consecutive billing history with TEP. We'll also need a good record of your hourly energy usage data, which isn't available for all customers due to an ongoing upgrade of TEP's meter information system. If our records are missing more than 7 consecutive days of usage data, more than 10 days of data during a billing period or more than 30 days of data during the last 12 months, you will not be able to use the Solar Analysis.
