The local climate helps too. Horsfield Bay enjoys mean daily solar exposure of about 16.3 MJ/m², or roughly 4.5 kWh/m² per day over the year. That strong sunlight is ideal for a solar hot water heating system or a high‑quality heat pump hot water system, especially if you already have rooftop solar.

Hot Water Rebates, Tariffs & Savings
For Horsfield Bay households, the numbers get even better once hot water rebate NSW incentives are factored in. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively provide an upfront discount on eligible solar hot water price / cost and heat pump hot water price / cost, while state heat pump hot water rebate and solar hot water rebate programs can further cut the hot water system price / cost. In some cases, electric hot water system rebate offers also apply when you replace old, inefficient gear. Combined, these rebates can trim the installed solar hot water price / cost or heat pump hot water price / cost by a substantial percentage, often shaving years off the payback period. When you add smart controls, timers or solar diversion so your electric hot water system runs mainly on your own solar, you can unlock hundreds of dollars a year in extra savings. For many homes, electric hot water vs gas hot water is no longer a close contest – especially when you compare heat pump vs solar hot water and choose the best heat pump hot water system or solar setup for your roof and budget.
