Before you buy

Two things to check

Local positionUse a market view to check local availability, approvals and warranty scope.

Ask the installer: Will the exact S6-GR1P model satisfy the site phase, array, MPPT, export-control and local grid requirements?

Verification & sources

Market context

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Strong evidence coverage

18 of 18 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
