Based on real data
Your analysis is not based on an estimate of your bill or any averages. We use your real Synergy usage data to make the tool as accurate as possible and tailored to your home.
Plan comparison
See how much your bill changes between different solar system sizes, different battery sizes, and different tariffs. Create your own system or input systems from quotes.

"We got three solar quotes ranging from $8,500 to $22,000 - each recommending a different system size, and none based on our actual usage. So we built the tool we wished we'd had."
