You may export to the grid if our system installed as part of the solarZero energy service generates more electricity than it can use and store. This will depend on the size of the system as well as the daily use of electricity in your home. You may generate surplus solar in the summer months as system sizing is based on average annual power usage, not for summer peaks. We will work closely with you to ensure that our whole system is working in the most effective way. One of the benefits of the solarZero service is the solar export credit that ensures that when you sell solar power you’re paid the same rate it costs you to buy energy, excluding network charges and GST.
