Solar installation in Perth continues to become more popular for homeowners. We wanted to go through 3 reasons why installing solar panels on your home is worth it.
(1) Solar panels in Perth
Owning a solar system in Perth has its perks. On average, Perth receives an annual average of around 5.8 hours of sun per day, according to PVWatts.
The more sun there is in a day, the more “energy” our solar system soaks up throughout those peak times. Depending on what system you decide to go with will determine how much energy you can save during the day. The table below shows a generic overview of potential output for solar PV systems in Perth ranging from 1.5Kw to 10Kw.
Installing solar panels in Perth has its benefits. We live in one of the world’s sunniest places, allowing us to take advantage of renewable energy whilst saving on our power bills.
(2) Saving money on your power bills
There are generally two ways that solar power helps households save money on their power bills:
Solar feed-in tariffs:
You are paid this rate for any ‘excess’ solar energy you send into the grid. The going rate in Perth is 10c/kWh in peak times between 3 pm-9 pm. And 3c/kWh during off-peak before 3 pm or after 9 pm.
Solar self-consumption:
This is when you use your solar energy directly, as it is being generated, reducing the energy you usually purchase from the grid (Synergy runs this). This is how your solar power will save you money in Perth.
There is a significant difference between the feed-in rate and the price you pay for electricity from the grid (on average, 27c/kWh). This means your solar energy is worth much more if you consume it yourself than selling it back to the energy grid. This differential – paired with the low price of solar power in Perth – also means Perth is one of the best cities to get a battery storage system installed on your system.
Solar installation in Perth:
Installing a solar system on your roof primarily means acquiring a small power station for your home. The energy accumulated from the solar panels can be used for multiple appliances within your home. They allow you to bypass your energy retailer for some of your energy needs. When using your energy, you don’t use all of it during daylight hours (when panels are producing power). You will still have to import fuel from the grid. When the sun goes down, you use more energy than your solar panels produce.
Solar energy demands from your home:
The demands vary by family size and how frequently appliances are used within the house. For example, the average three-person home uses around 20-25 kWh of energy per day over the year. The amount of solar energy that is ‘self-consumed’ will vary depending on your home’s electricity consumption pattern. Westsun Energy recommends you use at least 30% of the solar energy produced daily.
(3) Short payback periods for solar installation in Perth
Rooftop solar has become a no-brainer for homes and businesses across Perth. It is one of the best cities for going solar. This is due to ample sunshine, high grid electricity, and low solar system prices.
As mentioned above, the key to saving money on your solar is ‘self-consumption’. You are using solar energy directly with your home/business. By self-consuming your solar power, you avoid paying excessive grid electricity prices. The more solar energy you can use, the lower your energy bill. This can generally be achieved if you are home during the daylight hours.
The table below shows average payback periods for Perth’s 3kW and 5kW solar systems, including prices at different self-consumption levels (estimated ‘low’ and ‘high’ for each system size included). As you can see, paying back your solar system in under five years is highly achievable. Whilst your solar system will continue to operate for over 25 years.
Please also note that we have used average figures for pricing. Achieving even better outcomes is possible by finding a better deal and increasing your solar self-consumption rate.
