Solar in Watson — What You Need to Know

Watson is one of Canberra's original post-war suburbs with large blocks and single-storey homes — ideal for solar. ACT's zero feed-in tariff might seem discouraging, but the high retail electricity rate (25c+) means self-consumption is highly valuable. Watson households who shift loads to daytime (dishwasher, pool pump, hot water) can self-consume 70%+ of generation. The ACT's Sustainable Household Scheme offers 0% interest loans up to $15,000 for solar and batteries.
