An export limit is a DNSP-imposed cap on how much power your solar (or hybrid) system may send to the grid. Self-consumption can continue while exports are throttled. In 2026, export limits are one of the most common reasons oversized Australian arrays under-deliver on brochure payback stories.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.

High rooftop PV penetration can raise local voltage and congest distribution assets at noon. DNSPs protect safety and reliability by approving limited export — sometimes 5kW, 1.5kW or even 0kW on tough feeders. It is an engineering response, not a personal slight.
Inverter firmware settings, export control devices or dynamic operating envelopes hold AC export to the approved level. Your installer must commission the correct setting. A system that exports beyond approval can fail inspection or create liability issues.
If export is capped, prioritise daytime loads, hot-water control and batteries. A 13kW array on a 0kW export site can still cut bills — but only to the extent you use or store the energy. Re-run savings with the cap before paying a deposit.
Storage shifts surplus into evening peaks instead of fighting a noon cap. Federal support around ~$372/kWh usable since 1 July 2025 improves the economics on constrained streets. Confirm the hybrid's operating mode still respects network rules.
Ask which DNSP applies, what export limit is assumed, and whether the assessment is preliminary or approved. SAPN pre-approval culture differs from Energex or Ausgrid processes — local CEC-accredited experience matters.
Reject proposals that assume unlimited export when your suburb is known to be constrained. MrSolar quote packs should show the same export assumption across installers so price differences reflect hardware and labour, not fantasy FiT income.
