Solar in Tweed Heads — What You Need to Know
Tweed Heads occupies the unique position of straddling the NSW-Queensland border, with some streets literally divided by the state boundary. This creates Australia's most unusual solar market: homeowners on the NSW side of Boundary Street pay different electricity tariffs, access different rebate programs, and have different feed-in arrangements than their neighbours across the road. The NSW side uses the NSW network (Ausgrid/Endeavour rates), while QLD residents access Energex pricing. Both benefit from the same exceptional Northern Rivers solar resource — the Gold Coast hinterland's clear skies giving 5.5+ peak sun hours year-round. Tweed Shire Council (covering the NSW portions) has been supportive of solar, while Gold Coast City Council covers the QLD portions under different but equally accommodating planning rules. The practical advice for Tweed Heads buyers is to identify their state boundary position first — the rebate difference between NSW and QLD can affect total system cost by $400–600.
