The Comprehensive Guide to Buying Solar Panels in Perth, WA.

 

If you need advice on purchasing solar panels as part of a solar PV system, this guide is your go-to resource. It includes essential information and key considerations to help you find the best solar PV system for your home or business in Perth, WA.

 

Understanding How a Solar PV System Works.

 

Solar photovoltaic (PV) systems convert energy from the sun, a renewable energy source, into electricity to power your home or business. Living in WA, one of the sunniest regions in the world, makes installing solar panels a smart choice.

 

Here’s a breakdown of how a solar PV system operates:

 

1. Photon Release: The sun emits photons of light, which are units of energy.

   

2. Solar Panel Capture: These photons strike your rooftop solar panels, which contain cells made from materials like glass and silicon.

   

3. Energy Capture: The cells in the panels capture the sunlight, converting it into direct current (DC) electricity while the sun is shining.

   

4. Inverter Conversion: This DC electricity is fed into your solar inverter, which converts it into alternating current (AC) power, usable by your home and appliances.

 

 

 

The Potential Benefits of Installing Solar Panels in Perth.

​

Your Guide to Buying a Solar Inverter.

​

 

A solar inverter is the heart of your solar PV system, converting DC electricity into AC electricity for use in your home or business.

 

Types of Solar Inverters:

 

1. String Inverters:

   - Connect all solar panels in a system.

   - Similar to Christmas lights: if one panel is shaded or damaged, the entire system's production is affected.

 

2. Microinverters:

   - Built into each solar panel.

   - If one panel is shaded or damaged, it doesn’t impact the output of the rest of the system.

   - Ideal for roofs with shading or panels facing different directions.

   - Typically more expensive than string inverters.

​

 

Installation Tips.

​​

- Install your inverter as close to your electricity meter as possible.

- Place the inverter in a cool location away from direct sunlight, such as a garage.

- An accredited solar installer can recommend the best placement for your inverter.

 

Investing in a high-quality inverter is advisable, as this component is most likely to fail 10 to 15 years after installation.

 

​​

Racking and Mounting Your Rooftop Solar Panels.

​

 

Racking or mounting systems connect your solar panels to your roof. Your solar supplier should collaborate with you to determine the optimal layout for your solar PV system, taking into account your roof space, shading issues, and nearby trees or buildings that could affect performance.

 

In WA, the ideal angle for solar panels is generally 28 degrees to maximize sunlight exposure. Depending on your roof design and the chosen solar PV system, your panels might be mounted on tilt frames to achieve this angle.

 

The best position for your solar panels depends on several factors, but typically, north-facing panels receive the most sunlight in WA. However, east or west-facing panels might be more suitable based on your roof space, electricity usage patterns, and other considerations. For example, west-facing panels might be preferable if your household uses more electricity in the afternoon.

 

You can also adjust your electricity consumption habits, such as using timers on appliances, to maximize the power generated by your solar PV system.

 

 

 

Consumption Monitoring as Part of Your Solar PV System.

​

Consider installing a consumption monitor to measure the electricity flowing to and from the grid. These small devices, typically installed in your switchboard, are often offered as an optional extra when setting up a solar PV system.

 

While your solar inverter indicates how much solar energy your system produces—and some may provide additional consumption data—a dedicated consumption monitor offers more detailed insights. It allows you to see exactly how much solar power is being generated and when your home is using it. Understanding your electricity usage patterns can help you maximize the benefits of your solar investment.

 

 

​

Is Buying Solar Right for You?

​

Investing in solar panels can offer many benefits, but it may not be the best solution for every home or business. For instance, if you are renting or plan to move soon, you might not reap the full benefits of your purchase.

 

When considering a solar PV system, you should evaluate your electricity needs and usage patterns. Key factors include how much electricity you consume and when you use it. If your electricity usage is primarily in the morning or evening, you might find it challenging to utilize the solar power generated by your system.

 

Depending on your circumstances, you might need to adjust your consumption habits or consider installing a battery to make the most of your solar power generation.

​

 

 

What Size Solar PV System Do You Need?

 

The size of the solar PV system you need depends on several factors, including your budget, roof layout, and, most importantly, your electricity usage patterns. Additionally, consider any potential future increases in your electricity needs, such as purchasing an electric vehicle, retiring and spending more time at home, welcoming a new family member, or installing a pool or new air conditioning.

 

For a commercial solar solution, think ahead about how your business operations might expand and how this could affect your electricity consumption.

 

 

Choosing a Solar Installer in Perth, Western Australia.

 

The extensive solar industry in Australia provides numerous options when buying solar panels.

Many solar retailers offer financing options through third-party lenders. Before opting for financing, thoroughly research the lender and understand the loan contract's terms and conditions to avoid any unexpected costs.

 

 

Financial incentives and government rebates for purchasing solar in Perth, Western Australia.

 

A feed-in tariff is a credit or rebate provided to qualifying households or businesses with a solar PV system for the electricity they export back to the grid. In Western Australia, solar PV systems up to 5kW in size can benefit from the Distributed Energy Buyback Scheme (DEBS), with rates set annually by the State Government.

 

Residential and small businesses can avail of financial incentives through the Federal Government's Small-scale Renewable Energy Scheme, which relies on Small-scale Technology Certificates (STCs). These certificates, based on system output, can be traded on the market. Solar retailers may offer customers an upfront discount in exchange for the STCs generated by the system, known as a "solar rebate."

 

For solar PV systems exceeding 100kW, the Large-scale Renewable Energy Target applies, offering financial incentives in the form of Large-Scale Generation Certificates (LGCs). One LGC is earned for every megawatt-hour of electricity produced. LGCs, like STCs, can be traded on the market, with values subject to market conditions.

 

Unlike STCs created upfront, LGCs are generated continuously. This distinction means businesses with systems over 100kW can receive an ongoing solar rebate instead of an immediate discount on the solar PV system's cost.

The significance of solar energy in Western Australia's energy landscape

​

Maintaining a balance between electricity supply and demand is essential to ensure the stability of the South West Interconnected System (SWIS).

 

During mild, sunny days, rooftop solar PV systems typically produce high levels of power. If the grid's electricity demand is lower than expected on such days, it can pose a risk of supply disruptions and blackouts. With many homes and businesses in WA now equipped with rooftop solar PV systems, addressing the issue of 'low load' becomes crucial to mitigate blackout risks.

 

In managing 'low load', ensuring grid stability, and encouraging ongoing rooftop solar installations, the WA State Government introduced Emergency Solar Management (ESM). This initiative allows for the remote activation and deactivation of solar PV systems installed or upgraded since February 2022.

 

All newly installed or upgraded solar PV systems with inverters up to 5kW participating in the Distributed Energy Buyback Scheme (DEBS) must adhere to ESM regulations for remote management.

 

For solar PV systems exceeding 5kW in inverter capacity, an export limit will be imposed. This limit specifies the maximum amount of excess solar power that a rooftop solar PV system can feed back into the grid, beyond personal consumption.
