Perth is WA’s biggest city, and a great place to install a solar power system. With electricity rates rising, solar installation prices falling, and significant potential up-front financial subsidies through the federal government, now is a great time to find deals on solar power systems in Perth.
Why is Perth a good place for solar power?
Financial benefits of the Perth sunshine
When you own a solar system in Perth, more sunshine means more savings, so it’s useful to know what to expect. Perth receives an annual average of around 5.2 hours of peak sunshine per day. This means that, with a 1.5kW solar PV array operating at about 80% efficiency (typical), a home will generate around 6.2kWh per day on average throughout the year. A 3kW system will produce around 12.5kWh per day, and a 5kW system will produce around 20kWh per day.
Household electricity consumption and PV system generation
Household demand varies by the size of family and the appliances used and how frequently, but as a ‘base case’, the average 3-person home uses 20kWh per day, averaged over the course of a year. This means that with a 5kW solar system, the home’s energy consumption is just about covered by the system’s output provided that the system owners time can time their electricity consumption to match solar PV system power generation.
For residential customers: Currently, residents of Perth and surrounds are offered about 8c/kWh for excess solar power that they export to the grid–far less than the retail electricity rate. This means that the best strategy for Perth residents is to ‘self-consume’ as much of the power that the system generates as possible, while the sun in shining. By doing so, they will avoid incurring charges with their electricity retailer, and save money on their power bills. This, of course, will work best for those who are home during the day, or for businesses that operate during daylight hours.
For educational organisations & not-for-profit customers: Synergy offers generous feed-in tariff rates for not-for-profit, schools, and community organisations. This makes going solar a great investment. Read more: Solar Buybacks for not-for-profits, schools, and community organisations in and around Perth, WA.
Up-front Federal Government Solar Rebates for Perth
Under the federal government’s Renewable Energy Target scheme, households and businesses installing systems up to 100kW are awarded a greater or smaller number of small-scale technology certificates (STCs) depending on their location, the size of the system that they install, and the market price for STCs at the time of installation. These STCs contribute to the up-front cost of installing a solar PV system, ordinarily giving a discount of anywhere from 55-70c per watt for a system in or around Perth, WA.

How installing a solar system helps you cut your electricity bill in Perth
Depending on the electricity usage of the household, a solar generator could save Perth residents a significant amount of money on their power bills. It is important to keep in mind, however, that electricity consumption time management is the key to getting the most financial benefit of solar power. Since the Feed-in Tariff is only 7c/kWh, Perth residents get will want to avoid exporting to the grid as much as possible; solar electricity consumed at home is in effect worth as much as the the rates that they pay for electricity from the grid.
