A home battery being installed

Peace of mind for the long-run

With our Solar & Battery Guarantee, we make sure your system keeps performing for 20 years, so you don’t miss out on savings

More than just a warranty

Product warranties only cover the kit, not the labour or scaffolding to fit it. Batteries and inverters wear out, usually after their warranty has expired.

Every Solar & Battery Plus customer with a 20-year term gets our guarantee. You get monitoring, repairs and replacements, as well as product warranties and workmanship guarantees – so you’re protected for as long as you’re with us.

  • 5-year insurance-backed workmanship guarantee
  • 10-year product warranties for your battery and inverter
  • 25-year product warranty for your solar panels
