Separate imports from total demand
Grid purchases omit electricity supplied directly by existing solar. Select the correct consumption basis before using it to estimate the battery opportunity.
Battery retrofit proposals
Quote a battery around the solar already installed.
A battery retrofit starts with the system already on the roof. ArcSolar helps your team connect existing-solar assumptions, the household energy profile and proposed equipment before presenting the battery offer.

ArcSolar / Battery retrofit proposals
What changes for your team
Quote a battery around the solar already installed.
Make the existing system explicit
Confirm whether solar will stay, expand or be replaced. The proposed configuration needs to reflect that choice rather than silently assume a new installation.
Explain the battery assumptions
Review capacity, generation and the timing of household demand. A headline battery size alone does not establish the amount the household will save.
Setup and example

Confirm plan access, staff permissions and the connected workspace setup before using this workflow with a real customer.
- 1
Collect the baseline
Review the bill and available annual or interval evidence. Identify the existing solar setup and the actual import and export rates before modelling changes.
- 2
Prepare the configuration
Choose the supported solar or battery service combination and phase-compatible equipment. Review any required installation conditions with the responsible team.
- 3
Check a worked example
Illustrative inputs: grid purchases of 3,000 kWh and solar self-consumption of 2,500 kWh imply 5,500 kWh household use. This arithmetic is not a battery savings prediction.
Questions
Before you get started
Will every existing system suit a battery?
No compatibility guarantee follows from a savings estimate. Check the exact equipment and site requirements with qualified staff before issuing the proposed configuration.
Can a single bill establish annual demand?
A recent bill can provide evidence but may miss seasonal patterns. Explain the limitation and seek annual statements or interval data where available.
What if the forecast is not supportable?
Resolve the inputs and warnings before sharing. If a useful comparison cannot be supported, use the available omit-savings option and explain what is missing.
