Why is my electric bill so high?

The weather may be a contributing factor to a fluctuating electric bill:

  • If it's been colder than usual, your PV system will not produce as much electricity.
  • If it's been hotter than usual, increased usage of A/C or other similar systems may be increasing your electricity use.

An increase in household occupancy will increase energy usage and in turn increase your bill.

Additional products and appliances in your household, such as A/C, will increase energy usage.

If you feel there may be an issue with your PV system, please call AEI during regular business hours and we'll conduct a production validation if necessary.

Why is my PV production showing zero?

There's a good chance that your PV panels are still producing energy, but the monitoring system is down.
