- 10kW System: $8,500 – $14,000
A larger system allows homes to generate more electricity, resulting in higher savings in the long run. Government rebates also assist in greatly reducing the price of solar panels Perth WA.
Factors Affecting Solar Panel Prices in Perth
When calculating the solar panels Perth price, there are a number of significant factors that influence the total price. These range from the type of solar system to panel efficiency, installation difficulty, battery backup, and government incentives. The following is a detailed description of how each of these factors influences Perth solar panel prices.
1. Type of Solar System
The type of solar system that you have bears a significant impact on solar panels cost Perth WA to a great extent. There are three broad categories of solar systems available with different prices and advantages with them:
Grid-Connected Solar Systems
This is the cheapest and most popular alternative in Perth and throughout Australia. Grid-connected systems operate in harmony with the local power network. Your solar panels produce electricity during the day, and surplus energy is sold to the grid. You can receive feed-in tariff credits from your electricity company in turn, effectively reducing your power bill.
Advantages:
- Lower installation cost than off-grid systems.
- No requirement for costly battery storage.
- Option to sell excess power to the grid for money credits.
Shortcomings:
- Dependent on the grid, therefore power outages will impact supply.
- Feed-in tariffs have been on the decline over the years, thus self-consumption plays a greater role.
Off-Grid Solar Systems
For country or remote homes that do not have access to the grid of electricity, off-grid solar systems are an independent power source. They need high-capacity solar battery storage to supplement energy at night-time or under cloudy conditions.
Strengths:
- Totally independent of grid electricity.
- No electric bills.
- Ideal for remote homes where connection to the grid is expensive.
Weaknesses:
- Extremely costly to install (around $25,000+).
- Needs a large solar battery system, which has to be serviced and eventually replaced.
Hybrid Solar Systems
Hybrid solar system has the advantages of off-grid and grid-connected systems. Such installations have battery storage, so the owner can store excess energy but still maintain the grid as a backup.
Advantages:
- Reduces grid dependence but still enables excess energy export.
- supplies backup power during grid failures.
- Enhances energy autonomy and saves long-term electricity expenses.
Disadvantages:
- Higher in price compared to traditional grid-tied system because of battery expense.
2. Solar Panel Efficiency & Brand
Efficiency and brand of your solar panels are significant factors in solar power panels price. High-efficiency solar panels transform more sunlight into useful electricity, employing fewer panels and increasing energy production.
Efficiency Ratings:
- Traditional solar panels provide an efficiency rating of 16-19%.
- More expensive solar panels provide 21%+ efficiency, producing electricity per square meter.
Tier 1 Solar Panels:
- Manufactured by reputable companies with a sound financial background.
- Usually include 25+ years of performance warranty.
- Provide higher durability and reliability than low-quality panels.
Purchasing high-quality solar panels from Tier 1 companies provides long-term cost savings due to their slower loss of performance and ability to retain efficiency over decades.
3. Installation & Roof Factors
Installation process and the type of your roof structure determine solar panel prices. Installation factors that impact installation costs are:
Roof Type:
- Metal roofs are more affordable and have a simpler solar panel installation process.
- Tiled and Kliplok roofs have extra mounting hardware, hence, labor is more costly.
Roof Orientation & Shading:
- North-facing panels will provide maximum energy return in Australia.
- East- and west-facing panels yield less power but are still of use in morning and afternoon usage.
- Shaded areas will lower efficiency, so micro-inverters or power optimizers must be installed, which will be more expensive.
Electrical Upgrades:
- Some houses will need switchboard upgrades, priced at $500 – $2,000, to allow solar connection safely.
4. Solar Battery Storage
Installing a solar battery to your system significantly increases cost but increases energy independence. A battery stores unused solar energy for later use, reducing reliance on the grid.
Cost of Perth Solar Batteries
- Small (5kWh – 7kWh) Batteries: $5,000 – $8,000
- Medium (10kWh – 13kWh) Batteries: $8,000 – $15,000
- Large (15kWh+) Batteries: $12,000 – $20,000
Benefits of Solar Batteries
- Saves grid electricity usage by saving unused energy.
- Boosts solar self-consumption to 80–90%, thus the savings increase.
- Offers backup power in case of blackout or grid failure.
Drawbacks of Solar Batteries
- High initial expense, payback period prolonged to 7–10 years. This has been initially in a format suitable for presentation in the form of a slide.
- Lifespan limitations, as most of the batteries have an average lifespan of 10–15 years and need to be replaced.
Regardless of the expenditure, solar batteries are actually decreasing in price, and technological growth is increasing their lifespan and performance.
5. Government Incentives & Rebates
Government rebates lower the cost of solar panels Perth considerably under the Small-scale Renewable Energy Scheme (SRES). The scheme gives financial reward in the form of Small-scale Technology Certificates (STCs), lowering the upfront cost of a solar installation.
How Much You Can Save with STCs?
- Rebates usually pay for 30–35% of the system price.
- For a 6.6kW system, residential owners will get rebates of approximately $3,000 – $4,000.
State & Local Incentives
On top of federal rebates, some further savings are available through some Western Australian (WA) programs. These include:
- Feed-in Tariffs: Earn money selling excess solar energy back to the grid.
- Battery Subsidies (if available in WA): Sometimes, local government incentives provide a battery purchase subsidy.
Why Install Solar Today?
- Rebates decrease annually, so solar panels are more expensive in the future.
- Electricity prices increase, enhancing potential savings through solar.
- Technological advancements result in increased efficiency and reduced long-term cost.
Payback Period & Solar Panel Savings in Perth
- When will it repay your investment?
Payback period is a function of system size, electricity consumption, and feed-in tariff for electricity. Typically:
- A 6.6kW solar system repays within 3-5 years.
- A solar + battery system repays within 7-10 years since the initial cost is higher.
- How Much Can You Save a Year?
Homeowners will be saving $1,500 – $2,500 each year on power bills, based on their consumption and system performance.
Selecting the Best Solar System for Your Home
- Quality of Solar Panels & Inverters
Selecting top-quality solar panels and inverters guarantees long-term savings and system longevity. Select:
- 25+ years performance guarantee.
- Most reputable inverter companies with top efficiency ratings.
- Finding a Reliable Solar Installer
A 5+ year qualified CEC-accredited installer with good customer reviews and transparent warranty conditions is essential for correct system installation and maintenance.
- Future-Proofing Your Solar System

Avoiding Cheap Solar Deals
The majority of cheap solar deals can lead to:
- Poor quality of installation.
- Less efficiency and performance.
- Poor warranty coverage.
It is better to spend more for quality to ensure higher long-term dependability and affordability.
