Good Questions, Straight Answers

Can solar and storage remove all non-commodity charges?

No. Some costs vary with imports or timing and may be reduced. Fixed residual network charges and standing charges generally remain. The review should identify each charge separately rather than assume every avoided kWh saves every part of the bill.

Is battery storage worthwhile without solar?

It can be, depending on your tariff, peak-period demand and the cost of the system. Any assessment needs to account for charging energy, efficiency losses, degradation and applicable network charges.

What if we already have solar panels?

Existing generation can be included in the assessment. Generation and export data help establish whether storage could increase on-site use and how it would work alongside your current system.

What information is useful for an initial review?

Recent electricity bills, your tariff or supply contract, ideally 12 months of half-hourly consumption data, and details of any existing solar. Site and roof information help assess practical constraints.

Are savings guaranteed?

No. Results depend on your consumption, tariff, system design and operation. A useful business case sets out assumptions, ongoing costs and the effect of changes in prices or demand.
