Comparison tables
Simple solar comparison tables before you buy
These tables are not product rankings. They help you compare quote quality, battery claims, inverter details, feed-in value, and rebate support without needing a huge product database.
Solar quote inclusions
Use this to make two quotes easier to compare.
| Area | Good quote includes | Weak quote sign |
|---|---|---|
| Hardware | Panel, inverter, battery, optimiser, and mounting model numbers | Total price only |
| Financials | STC value, battery support, state rebate, loan, and VPP offers separated | One bundled discount with no source |
| Design | Roof layout, orientation, shading assumptions, export limits, and annual production | Generic production estimate |
| Support | Workmanship warranty, product warranty, monitoring, and claim pathway | Warranty claims left vague |
Battery warranty comparison
Check these before trusting a battery payback estimate.
| Check | Why it matters |
|---|---|
| Usable capacity | Compare usable kWh, not only nominal capacity |
| Warranty | Look for years, cycles, throughput, and end-of-warranty capacity |
| Backup | Confirm if backup is included, which circuits are backed up, and extra hardware cost |
| Rebate eligibility | Confirm approved product, installer, battery size, and commissioning rules |
Inverter red flags
| Red flag | What to ask |
|---|---|
| Missing model number | You cannot compare efficiency, warranty, monitoring, or compatibility |
| Poor inverter location | Heat, rain, and direct sun can shorten life |
| No monitoring detail | You may not know when the system underperforms |
| Battery-ready claim without detail | Ask what future battery options are actually supported |
Feed-in and rebate checks
Feed-in tariffs should be compared against usage rates, supply charges, and time-of-use pricing. A higher export rate can still produce a worse bill.
Rebates should be separated from finance support. STCs, state rebates, VPP incentives, and loans are different things and should not be bundled into one unexplained discount.
