Think of solar panels more like apple trees – we need a fairer approach for what we use and sell
When solar panels generate more energy than a household is using, the excess electricity can be exported to the grid.
- When solar panels generate more energy than a household is using, the excess electricity can be exported to the grid.
- Rooftop solar regularly provides more than a quarter of daytime electricity across the National Electricity Market.
- The measures in place are costing households that are generating solar power, but also non-solar owners and network operators.
- We suggest solar panels should be thought of a little more like apple trees.
What’s not fair about the current system?
- Other mechanisms are also being put in place to allow AEMO to occasionally curtail output from rooftop solar to maintain power system security.
- However, such measures not only reduce how much electricity is flowing from a home to the grid, but the entire output of the home’s rooftop system.
- Nor is it fair for distribution businesses to build more poles and wires to accommodate everyone’s solar exports all the time.
- Or if the system operator has to buy more reserves to cover for the uncertainties of rooftop solar output.
It’s time to rethink the social contract for grid electricity
- How should households with these growing distributed energy resources interact with the grid in future?
- We reckon the social contract for grid electricity needs to evolve from the pay-plug-play expectations dating from the 19th century to a two-way engagement to support fairness for all.
- Apples aren’t an essential service, apple trucks aren’t a regulated monopoly, and the supply and demand of apples doesn’t need to be balanced every second.
- However, the principles remain – especially for a future where apple trees (rooftop solar) and apple warehouses (home batteries and electric vehicles) are everywhere.
A fairer balance of rights and responsibilities
- In our research paper we distinguish between rights for passive use (using your own rooftop solar electricity) and responsibilities for active use (selling electricity).
- We have an opportunity now to make it work better and be fairer for all of us.
