Residential Solar Panel Costs and Savings Now

This entry was posted in Solar Services on by .

Perhaps, the single most common question we’re asked by homeowners contemplating residential solar is how much savings is possible. It’s a fair question, and one that we’re happy to answer. Here are just a few of the financial details to help you make your decision to go solar or not.

The Initial Cost

An installed, residential solar system in Arizona costs approximately $2.79 per watt prior to incentives. This amount is fairly consistent among cities in the greater Phoenix area, as well as in Flagstaff and Tucson. After claiming the federal tax credit of 26 percent and Arizona’s state tax credit, the price drops to just $2.00 per watt. In other words, the average cost of a 5kW system may cost around $14,000 before incentives and just over $9,000 after claiming the incentives.

Why Arizona Homeowners May Want to Consider Solar

The growth in solar power can be connected to Arizona’s Renewable Portfolio Standard law which requires the state’s investor owned utilities (IOUs) to obtain 15 percent of their power from renewable sources by 2025. If they aren’t doing this, they will receive fines.
There’s also the simple fact that Arizona gets more sunshine than any other state in the United States. Consider that solar panels in Arizona produce nearly three-quarters more power than in cloudier states like Washington, New York or Ohio. Greater solar output means that fewer solar panels are needed to achieve a desired output.

What About Net Metering?

In December 2016, net metering was repealed by the Arizona Corporation Commission (ACC) and was replaced with a system that is somewhat less generous, but still gives homeowners something similar to retail rates for excess solar power they export to the grid. This system is referred to as feed-in tariff rather than net metering.

In the case of APS, they value exported solar generation at 10.45 cents per kWh generated. That’s a fairly good deal when you consider that the average cost of electricity is 12.12 cents kWh. For 1 kw of solar panels installed on a south-facing roof in the greater Phoenix area, you can typically expect to generate 1,752kWh each year. And, the average 2500 square foot home in the greater Phoenix area will require approximately 25 panels to be fully powered.
