Solar Adoption Statistics on the Central Coast
More than 10,030 small-scale solar systems have been installed across Gosford and the wider 2250 postcode area on the Central Coast, delivering a combined capacity of approximately 75,887 kW.
With a population of around 66,900, this works out to approximately 1,134 watts of solar capacity per person, compared with the Australian average of around 1,228 watts per person. There are approximately 29,012 dwellings across the 2250 postcode area, equating to around 35 solar systems per 100 dwellings, compared with the national average of approximately 42 per 100 dwellings.
These existing solar systems generate a conservative estimated 286,000 kWh of energy each day, enough to power the equivalent of around 17,900 homes based on average household electricity consumption of 16 kWh per day. At 34 cents per kilowatt-hour, that represents approximately $35.5 million worth of electricity every year.

Designing the Right System for Your Central Coast Property
Understanding how and when you use energy is key to designing the right solar system for your home. By customising the system’s size and orientation to suit your energy habits, we make sure you get the most from your solar investment.
Afternoon energy use: If your peak usage is in the late afternoon, we recommend positioning some panels to the west. This setup captures sunlight during the later hours, helping extend the period of free energy use.
Home all day: For those at home throughout the day, opting for a larger solar system and adding a battery allows you to store excess energy. This way, you can continue enjoying solar power even when the sun isn’t shining — see our dedicated Solar Battery Storage page for options.
With New South Wales enjoying an average of 10 hours of sunshine in summer and 5 hours in winter, solar power is a great fit for homes on the Central Coast.
