How the bars work

Each bar puts a published or calculated figure on our fixed 0 to 5 visual scale. These are not official product ratings, customer review stars or an overall recommendation. Scores are rounded to one decimal and stay between 0 and 5. Search and selection do not change them.

Usable storage

40 usable kWh is the 5-point reference. More storage can run appliances for longer, but is not automatically better value. Compare the listed module count and choose capacity for your usage; backup power is a separate figure in Specs.

Parts warranty

15 years of main-product parts cover is the 5-point reference. Free registration requirements are shown in Specs; paid extensions are excluded. Accessories, labour and installation may have separate terms. Battery usage limits can end cover sooner; heat-pump component and tank terms are listed separately.

See note means the available source does not give a comparable figure. The note explains what the brand publishes, and Specs includes the exact source and conditions.

Larger capacity is not automatically a better match. Choose equipment sized for your home and needs.

Creditex is listed by ESIA as part of the Emerald Group. Emerald products use the same comparison criteria as other brands.
