How to Read a Dial Electric Meter

How to Read Your Meter
Your electric bill contains all the information you need about your power usage. However, if you would like to read your own meter, here's how to do it.

As you can see from the arrows in the illustration below, the dials on your meter move alternately clockwise and counter-clockwise.

Always read from right to left.

When a hand points between two numbers (as in A, B, C and E) always read the lower number.

Sometimes a hand appears to be pointing directly at a number (as in D). To find out if that number has actually been reached yet, look at the dial to its immediate right (in this case, C). If the hand on dial C has passed zero, then write down the number on dial D to which the arrow is pointing (4). If C has not passed zero, as is the case in this example, write down the number that is lower than the one on dial D to which the arrow is pointing (3).

The correct reading for this meter is 13924 kilowatt-hours.

For information on how to read a net meter, see meter handout.

Solar is incredibly cheap, less than 10% of the cost of buying power from the utility here in Hawaii

This Actual 20 panel System produces at 3.3 cents per kWH.    Larger systems like 30 panels can be under 2.9 cents.
