3. Upgrade the Panel

The actual upgrade involves replacing the old panel with a new one that has higher capacity and modern safety features. This process usually takes a few hours to a day, depending on the complexity of the job.

4. Inspect and Test

After the upgrade, a local inspector will verify that the work meets safety standards. Your electrician will then test the new panel to ensure it functions correctly with your solar system.

Get Rid of Roof Top Isolators

It’s seldom enforced, but network rules mandate that your solar power system should be inspected by an electrician every five years. This is particularly important for the dreaded rooftop isolators (RTIs). These fire-prone DC switches are a risk, and removing them is an opportunity you shouldn’t miss.

How to Legally Ignore Inverter Limits

If you want more capacity than the networks typically allow, the solar inverter standard AS4777 now defines an inverter that’s an “independent” power supply, separate from a conventional grid-tied inverter. By configuring a Selectronic SP-Pro inverter correctly, you can create a large independent system and treat the grid as a backup generator.

The SP Pro acts as a gateway, allowing you to have almost unlimited solar and battery capacity downstream, even though you can’t export power to the grid. This setup provides you with a reliable backup while maximizing your solar energy use.

Benefits of Upgrading

Upgrading your electrical panel offers several benefits, including improved safety, increased capacity, and enhanced efficiency of your solar system. It also prepares your home for future technological advancements and energy needs.

By following these guidelines, you can ensure that your solar system operates at peak efficiency and meets your household’s energy demands. If you have more questions or need further assistance, feel free to reach out to a professional.

How feed-in tariffs work

The energy generated by your solar power system is transformed into electricity for use in your home. Surplus electricity can be fed back into the grid, and you might receive a payment for this excess, known as a feed-in tariff.

Residents of South East Queensland can obtain a market feed-in tariff directly from their electricity retailer. With no set rate for electricity fed into the grid, retailers provide competitive market-based tariffs, so it’s advisable to compare offers for the best deal.

Those in regional Queensland have access to a regional feed-in tariff.

New customers are not eligible for the former Solar Bonus Scheme feed-in tariff. For more information, visit the Queensland Government’s feed-in tariffs page under Homes and Housing at www.qld.gov.au.

In Queensland, solar power is a favored option due to the ample sunshine, playing a significant role in the state’s renewable energy portfolio. Opting for a solar electricity plan in QLD contributes to a greener, more sustainable future, marking progress in reducing fossil fuel dependence and addressing climate change. Annually, thousands of Australian homes make the switch to solar. Given the substantial cost of solar panels, it’s crucial to ensure that your solar energy plan is tailored to your requirements to maximize your investment. For novices, particularly those installing solar for the first time, understanding feed-in tariffs (FiTs) and monitoring exports can be complex without a benchmark for what constitutes a ‘good deal.’ Our aim is to clarify the essentials and present several competitively priced energy plans with solar benefits. In evaluating solar electricity plans in QLD, a variety of choices exists, each with distinct features and advantages. Some plans offer reduced rates, while others boast higher feed-in tariffs,

Solar buyback electricity plans, also known as feed-in tariffs, are integral to solar electricity strategies. They permit the sale of surplus solar energy back to the power grid. The selling rate is subject to variation based on your energy provider and the chosen plan. While these plans can yield extra savings on energy bills, comprehending your plan’s specifics is vital. Ultimately, solar buyback plans can significantly enhance the financial benefits of your solar installation.

What should I look for in a solar energy plan?

Solar energy plans are not one-size-fits-all. It’s best to select a solar electricity plan that aligns with your system and usage needs. Here are some general suggestions for the type of energy deal that may suit your system and household needs, based on your solar panel output and daily energy use.

If your solar panels only partially cover your daytime power usage: You might want a solar energy plan with low electricity usage rates. This is because you’ll still depend heavily on the grid to meet your energy needs. In this scenario, a high feed-in tariff (FiT) would be unnecessary, as you’re not exporting much surplus solar energy to the grid, if any.

If your solar panels can power your entire day: You should look for a solar energy plan with favorable electricity usage and supply rates. This is because you’ll need grid electricity in the evenings when your solar panels aren’t active. A plan with a high FiT might not be beneficial, as you’re likely not exporting enough surplus to make a significant return. Additionally, it might mask higher usage and supply rates.

If your solar panels produce more energy than you use in a day: You might prefer a solar energy plan with a higher FiT. This is because your system will begin exporting the unused solar energy back to the grid. A solar battery could also be useful to store excess energy for later use. If opting for a higher FiT plan, ensure that the rates are competitive for times when you need grid electricity.

• If you have solar panels with battery storage: You might look for a solar energy plan with a reasonable FiT and competitive energy rates. Your energy plan should be cost-effective for when your storage system is depleted or exceeds its capacity. Households that are self-sustaining and rarely use grid electricity should consider their energy plan carefully to ensure it meets their specific needs.

Here are some concise notes on solar system sizing:

A 6.6 kilowatt (kW) system is currently the most popular size.

When considering solar for your home, or expanding your current system, it’s crucial to determine the optimal size for your needs. We have detailed guides on this subject (see resources below), but generally, a 6.6kW solar system is cost-effective and complies with most of Australia’s network rules for easy approval and eligibility for feed-in tariffs. Such a system typically generates ample energy, often enough to charge a battery bank should you decide to add one later.

Even without a battery, surplus solar energy not used immediately in your home can earn you credits through solar feed-in tariffs on your electricity bill, so having a system that produces more energy than you use is not problematic.

Resources for choosing the correct solar and battery system size include:

– Understanding kilowatts vs kilowatt-hours: Power, energy, and capacity in solar and batteries

– Solar Choice Solar Payback & ROI Calculator (important for financial considerations)

– Guides on selecting the right size for a solar PV system

– Quick tips on solar and battery system sizing

– Comparisons between 5kW and 3kW solar systems for better investment decisions

– Solar Choice’s estimator for solar and battery sizing and payback calculations

– Explanations on the limitations of grid-connected system sizes

Size limits are generally governed by the new AS/NSZ 4777 standard, which most networks adhere to, allowing for the following system sizes:

– Single-phase connection (typical in homes): Up to 5 kilowatts (5kW or sometimes referred to as 5kVA)

– Three-phase connection (found in some homes and many businesses): Up to 30kW (30kVA)

Most networks operate a ‘pre-approval’ process, automatically approving connections that meet specific criteria, including system size/capacity, although these criteria can vary between networks.

The size limits set by networks are not absolute. Larger systems may be approved for your property, but this often involves more bureaucracy, extended waiting periods, and potentially additional fees.

Size limitations also affect eligibility for solar feed-in tariffs. Systems exceeding a certain size might be installed but not allowed to export energy back to the grid, disqualifying them from feed-in tariff benefits. Consequently, households should aim to ‘self-consume’ as much solar energy as possible to avoid waste. Occasionally, the feed-in tariff threshold is determined by the electricity retailer, not the network.

Consult with a qualified solar installer to determine the best system size for your needs.

Rules may vary, so it’s important to ask questions. The specific implementation of these rules can differ from one network to another and even within different areas of the same network. This variation leads to several key questions that should be asked. You can contact your local network company, your electricity retailer, or discuss with installers to understand your options.

Key questions include:

– Does the limit apply solely to solar inverter capacity, or does it include battery inverter capacity as well?

Modern grid-connected solar systems automatically export surplus solar energy to the grid. However, battery systems with dedicated inverters are not primarily designed for this purpose. Consequently, some networks may not include battery inverter capacity in the maximum size limit, although most do.

– Is the installation of export limiting or export control technology on your system required? What about solar smoothing?

Network issues with grid-connected systems often stem from solar energy entering the grid and disrupting the local network’s electricity quality. A common solution is the implementation of export limiting functionality, which restricts your system from exporting solar energy beyond a certain threshold (e.g., a 3kW limit for a 5kW system), or in some cases, completely prevents export. This control can be achieved with certain inverters or additional third-party equipment designed for this purpose, sometimes referred to as grid protection.

Conclusion and Next Steps

Understanding the solar system size limits in QLD is crucial for maximizing your solar investment.

Stay updated on policy changes and consult with a qualified solar installer to make informed decisions.
