Path-Q Solar

What battery warranty terms address declining capacity?

Answer

Look for guaranteed retained capacity, measurement conditions, throughput or cycle limits, calendar term, exclusions, reserve settings, temperature requirements, labor, replacement remedy, and transferability.

Key points

  • A capacity percentage is meaningful only with defined test conditions.
  • Throughput limits can end protection before the calendar term.
  • Check whether replacement is new, refurbished, or prorated.

What it depends on

  • Exact warranty document
  • Operating profile
  • Installer and manufacturer responsibilities

Risks and trade-offs

  • Warranty claims may require extensive data.
  • Capacity protection may not cover labor or lost savings.

Information you may need

  • Warranty terms
