How do I prepare my PV solar system for a storm or hurricane?

There is actually nothing special needed to prepare your PV system. Government building codes require PV systems to be installed securely enough to handle most severe weather events. Your system will shut itself off in a grid outage and power itself back up when power is restored. This article also covers how to care for your system after a storm.

Will my solar array continue to produce power if the electricity goes out?

For Net Metered solar systems your system will NOT continue to produce power if the electricity goes out. In order to protect the utility company’s workers that may be servicing the power lines in the event of an outage, the system will automatically shut off, only to power back up when service is restored.

For systems under the self supply program, your solar array will still produce power, sending it to your battery for home consumption.

Why do I still get a bill from the utility company if my system is offsetting all of my usage?

The utility generally applies a minimum charge for their service of between $15 and $20, depending on a few different variables. On the months when you use more electricity than normal, your utility will provide you with any extra kilowatt hours you need, and usually the extra credits you had in the bank (Net Energy Metering) will offset this extra usage.

Why is my bill still high?

If your bill is still high after your panels have been installed, here are some questions to ask:

  • Check your Air Conditioning Usage—have you had a system installed, or used your current system more?

  • Have you had visitors stay with you during the billing cycle?

  • Check you monitoring, is everything operating as it should be?

How Does Self Supply work?

Under the Self Supply program, excess daytime electricity production is stored in batteries for use at night.

  1. During periods of prolonged inclement weather, or abnormally high usage, power can still be supplemented with utility provided power.

  2. As an added benefit, homes under the self supply program can be setup to provide emergency backup power during a grid outage.

How does Net Energy Metering work?

1. Your PV panels will produce energy throughout the day. 
2. The energy that is produced will be used to power your home. 
3. Any extra energy that your home doesn’t utilize will then be sent to the grid. That energy is stored up in your account as credits that you can use at a later time. 
4. If the energy needs in your home are greater than your production, you will pull energy from the grid.
