Solar Feed-in Tariff Quote Checks
Check how feed-in rates are used in savings estimates before you compare quotes.
Decision check
Feed-in tariffs can change by retailer and tariff plan, so a quote should not make savings look stronger by assuming an unrealistic export value.
Savings should not rely only on exports
Most quote comparisons should focus on self-consumption first. Export rates help, but daytime usage and evening grid import usually decide the real value.
Ask what tariff was used
The quote should state the import rate, feed-in rate, controlled load assumptions and whether the estimate uses your actual bill or a generic profile.
Battery value depends on the gap
A battery can look better when the import price is high and export value is low, but usable capacity, losses, warranty and backup hardware still matter.
Apples-to-apples comparison
Compare the quote, not just the price
Two solar quotes can look similar but use different panels, inverter capacity, roof assumptions, warranties and exclusions. These are the details worth checking before you commit.
System design
System size, roof layout, shade, inverter choice, export limits, and production estimate.
Equipment quality
Panel model, inverter model, battery option, product warranties, and installation warranty.
True price
Gross price, STC discount assumptions, finance cost, extras, switchboard allowances, and monitoring.
Installer fit
Local service area, accreditation, reviews, support process, and experience with similar roofs.
