How to Check your Solar Production Online with APS

With solar being so low maintenance, having tools to determine that it is working correctly is important to many customers. In addition to a green light on an inverter, the best way to check this is online through your APS account. Read below for step-by-step instructions on how to check your solar production.


Step 1: Log in to your online APS Account

Go to and log in with your username and password. If you do not have this information, contact APS directly to have them walk you through registering for an online account.

Step 2: Navigate to your Solar Daily and Hourly Usage Data

To do this, click on the main “my energy” drop-down menu and from there click “daily and hourly usage”. 


This will take you to your general electricity usage data. To access information specifically for solar, you will need to click the arrow next to “for service at” and select the address with an asterisk(*). If there is no address listed with an asterisk, contact APS for further assistance.


Step 3: Compare your Daily kWh with your Statement of General Performance

Your screen should now show a graph similar to the one below. Place your cursor over one of the blue bars. This will show the on-peak production, off-peak production, and the total.  Take this number and compare it to the Statement of General Performance provided with your initial solar quote (if you do not have this, email us at to request a copy). If these numbers are not within a few kilowatts of each other and this happens longer than a 7-day period, please consider the following factors:

  • Rainy or cloudy weather- solar only functions completely when the sun is visible in the sky.
  • Extreme heat- solar panels are manufactured to function without production loss in heat up to 105 degrees.
  • Shading- check to make sure that no new trees or buildings are shading your solar panels.

If none of these options are a factor, then click here to submit a service request.


Please note: If you are looking at your bill, the kilowatts credited is only the total amount of energy you have sent back to APS, not the total production of your solar system.



Other Items to Consider

Are you using more energy now than before you got solar?

One common misconception among solar owners is that when you get solar installed you are able to use way more energy than before without the additional cost. While this is in true most places, the utility rates in Arizona aren’t built with that in mind, with most containing steep demand charges and other factors that if go unchecked drive up your bill. If you notice that your bill is higher than usual, another great thing to do is to compare your energy usage this month with the same month last year.

To do this, go back to the arrow next to “for service at” and select the address without the asterisk(*). This screen will show you your on-peak usage, off-peak usage and the average temperature for the month selected. Review the month’s information then change the date using the calendar icon to the right. Compare this data to see if your usage changed from year to year.

How much of your bill is fees?

Another thing even non-solar owners miss is exactly how much of your bill is due to APS fees and taxes. To find this information, you will need to view a copy of your bill. If you don’t have a hard copy handy, you can also view these online (If you do have a hard copy, skip to the last image in this post). To do this, select “my bill” on the APS website and from there click “previous bills”.


On this page, you can view up to 24 of your previous bills. Select the month you want to view, then click “view bill” to the right.


On the last page of your bill, there will be a column on the left containing a breakdown of all the fees and charges included in the total cost. The items circled below in green are the charges for the electricity you used. The rest of the charges are other fees required by APS. To get a breakdown of what these fees mean and for help understanding the rest of your bill, click here.
