How Solar Batteries Work

How Do Solar Batteries Work?

A solar battery system empowers your home by storing solar energy generated during the day, allowing you to use that stored energy when the sun isn’t shining. This approach reduces your reliance on grid power and gives you control over your home’s energy supply.

 

The Solar Battery Process:

 

  1. Energy Generation: During daylight, your solar panels convert sunlight into electricity. This clean, renewable energy can be used immediately to power your home.

  2. Battery Storage: Any excess solar energy produced by your panels is directed into a battery. This stored energy is saved for later, ensuring your home has a reserve to draw from during the evening or on overcast days.

  3. Grid Connection as Backup: When your solar panels or battery don’t meet all your energy needs, the system connects to the grid to ensure your home has a steady power supply. This hybrid setup helps you enjoy a reliable energy solution while minimising grid use and cutting down on electricity costs.

 

With a well-integrated solar battery system, you’re set up to make the most of Cairns’ abundant sunshine. It’s a smart step toward energy independence, sustainability, and savings.

A fantastic job by the team worked so hard and finally cleaned up so well that you would not know that they had been there. Overall I could not be more satisfied with the service I received from every member if the Hielscher Electrical team and would be happy the recommended them to any one looking for a solar system installer.

Solar Storage Components

What Components Make up a solar storage system for my home?​

A solar storage system is made up of several key components that work in harmony to capture, store, and manage solar energy for your home. Each element plays a critical role in ensuring you have reliable and efficient access to clean energy, even when the sun isn’t shining.

 

Key Components of a Solar Storage System

 

  • Solar Panels: Solar panels are the starting point, capturing sunlight and converting it into direct current (DC) electricity. This energy can either be used immediately or stored for later use, providing a foundation for sustainable power in your home.
  • Racking: Solar panels are securely attached to your roof using a robust racking system. Quality mounting is crucial to protect both your panels and roof, ensuring long-term durability.
  • Hybrid Solar Inverter: The inverter converts the DC electricity generated by the solar panels into alternating current (AC) electricity, making it usable for household appliances. This essential component manages the flow of energy to ensure efficient use.
  • Solar Storage Battery: The battery stores excess solar energy generated during the day. This stored energy can then be used at night or during cloudy days, giving you a reliable source of power regardless of sunlight availability. Many modern solar batteries use lithium-based technologies like Lithium Ferro Phosphate (LFP) for safety, durability, and long life cycles.
  • Switchboard: The switchboard directs the energy generated by your system to where it’s needed most. It powers household appliances first, then sends any excess energy to the battery for storage. When the battery is fully charged and extra energy is available, it can be fed back into the grid, often earning you credits on your electricity bill.
  • Transfer Switch: The transfer switch automatically disconnects your home from the grid during power outages, allowing the solar storage system to power essential appliances safely without backfeeding electricity to the grid. Once grid power is restored, the transfer switch reconnects your home to the grid, ensuring continuous energy flow.
  • Protected Loads Panel (PLP): The Protected Loads Panel, or PLP, is a sub-panel containing critical circuits that need backup power during outages. This typically includes essential appliances like the refrigerator, lights, Wi-Fi router, and any medical or safety equipment. The PLP ensures that only these vital loads draw power from the battery when the grid is down, maximising battery life.
  • Remote Off Switch: For safety, the remote off switch provides a quick way to turn off the solar storage system in emergencies. Located near the home’s main electrical shutoff, it’s easy to access for emergency responders.
  • Software Controls: The software controls manage the flow and usage of energy in your system. They allow you to set preferences for different modes, such as backup, self-consumption, or time-of-use savings. You can adjust settings based on your energy needs or weather conditions, providing flexibility and optimising battery use.
  • Internet Connectivity: Many solar storage systems connect to the internet, allowing remote monitoring and control of the system. This connectivity enables you to track energy production, battery levels, and usage in real time, and receive software updates or diagnostic support if needed.

 

With these components working together, a solar storage system provides an efficient, resilient, and sustainable way to power your home, reducing reliance on the grid and maximising the benefits of Cairns’ abundant sunshine.

Why Quality Matters

Why quality count's when it comes to solar batteries in Cairns

Choosing a high-quality solar battery for your home in Cairns is a crucial step toward reliable, efficient, and safe energy storage. While budget options may seem attractive upfront, quality components deliver better performance, longevity, and peace of mind. Here’s why investing in a premium solar battery system is essential:

 

Reliable Performance in Tropical Conditions

Cairns’ climate can be challenging, with high humidity and intense sunlight. Quality solar batteries are designed to withstand these conditions, ensuring your system remains efficient and safe in even the most extreme weather. Inferior batteries can deteriorate quickly, leading to reduced storage capacity and more frequent replacements.

 

Extended Battery Lifespan

High-quality batteries, often equipped with advanced lithium-ion technology like Lithium Ferro Phosphate (LFP), are designed for durability and have a higher cycle count—meaning they can charge and discharge many more times over their lifespan. Cheaper batteries may degrade sooner, impacting both performance and your return on investment. A quality battery system is built to last, delivering reliable energy for years.

 

Enhanced Safety Standards

Quality batteries undergo rigorous testing and are manufactured to high safety standards. This is especially important for home storage, where safety issues with cheap or poorly made batteries can lead to potential hazards like overheating or electrical faults. Opting for a reputable battery brand ensures better safety features, reducing risks and keeping your home and family safe.

 

Greater Efficiency and Power Supply

High-grade solar batteries have higher efficiency ratings, which means more of the energy produced by your solar panels is stored and available when needed. They also typically offer better power ratings, so they can handle larger household appliances without any issues. This efficiency is particularly valuable in Cairns, where you want to capture and store as much solar energy as possible.

 

Dependable Backup Power During Outages

Quality batteries are more dependable in providing backup power during grid outages. They can sustain power for essential appliances and are often optimised to continue charging from solar panels even when the grid is down. This feature is particularly beneficial in storm-prone regions like Far North Queensland, offering you a continuous energy source when you need it most.

 

Better Return on Investment (ROI)

Investing in a quality solar battery system pays off over time. Premium components perform better and last longer, meaning fewer repairs and lower replacement costs. With the additional energy savings, reliable backup power, and extended lifespan, a high-quality battery provides a stronger return on your initial investment compared to cheaper alternatives.

 

At Hielscher Electrical, we prioritise quality in every aspect of your solar battery installation. From selecting industry-leading batteries to ensuring expert installation, we’re committed to providing Cairns homeowners with a system that is built to perform, last, and keep your home powered safely for years to come.

Solar Battery Rebates and Incentives

What Solar Battery Rebates and Incentives Can I Get in Queensland?

What Solar Battery Rebates and Incentives Can I Get in Queensland?

Queensland has offered several incentives over the years to encourage homeowners to adopt solar power and battery storage. While the state’s Battery Booster Program has recently ended, there are still valuable incentives that make solar installations more accessible.

 

1. Small-scale Technology Certificates (STCs)

STCs remain the primary incentive for Cairns homeowners installing solar systems. Provided under the federal government’s Renewable Energy Target, these certificates can significantly reduce the upfront cost of your solar installation.

  • How STCs Work: The number of STCs you’re eligible for depends on the size of your solar system and your geographic location. The larger your solar setup, the more certificates you receive.
  • STC Value: Like shares, STCs are traded on the open market, so their value can vary. This fluctuation impacts the final cost of your system, so it’s essential to obtain quotes that reflect current STC values.
  • Expiry: The STC program is scheduled to phase out by 2031, with the number of certificates decreasing each year. Installing sooner means you’ll benefit more from the remaining incentives.

 

2. Solar Feed-in Tariffs (FiTs)

Feed-in Tariffs (FiTs) reward homeowners who export excess solar energy back to the grid. While FiT rates have generally decreased in recent years, they still provide an opportunity to earn a return on your solar investment.

  • How FiTs Work: In Queensland, most FiTs are net-based. This means you’re paid for any electricity exported to the grid after subtracting your home’s usage.
  • FiT Rates: FiT rates vary by energy retailer and can range from 5 to 16 cents per kilowatt-hour (kWh). Choosing a plan with a competitive FiT rate and maximising your own energy use can help you save even more on energy costs.

 

3. Battery Booster Program (Now Closed)

Queensland’s Battery Booster Program, which provided rebates of up to $4,000 for home battery installations, closed to new applicants on 8 May 2024. Homeowners who received conditional approval before the cutoff date have up to 90 days to install and claim the rebate.

 

While there’s currently no active subsidy for batteries in Queensland, advances in battery technology and decreasing costs continue to make battery storage an appealing option for energy independence.

Impact on Electricity Bills

Will I Still Pay Electricity Bills with Home Solar Batteries Installed?

Installing solar panels and a home battery can significantly reduce your electricity bills, and in some cases, even eliminate them. However, the extent of your savings depends on how your system is set up, your household’s energy use, and how much of your electricity you can generate and store with solar.

 

How Solar and Batteries Help Reduce Your Electricity Bills

  1. Self-Consumption Savings
    The more solar energy you use directly in your home (known as self-consumption), the less you need to buy from the grid. Every kilowatt-hour (kWh) of solar energy you use is a kWh you’re not purchasing from your energy retailer. This can lead to substantial savings, especially during daylight hours when your solar system is generating power.

  2. Battery Storage for Nighttime Use
    A home battery allows you to store excess solar energy generated during the day for use at night or during cloudy days when your solar panels aren’t producing as much. By using stored energy instead of drawing from the grid, you reduce your reliance on grid power, further lowering your electricity bills.

  3. Feed-in Tariffs (FiTs) for Exported Solar
    When your solar panels generate more electricity than you’re using, the surplus can be exported back to the grid, earning you a credit on your electricity bill through a Feed-in Tariff (FiT). While FiT rates vary and are typically lower than the cost of buying electricity, this still provides an additional way to offset your electricity expenses.

 

Will a Battery System Eliminate My Electricity Bill?

In some cases, a well-sized solar and battery system can almost eliminate electricity bills, especially for homes with high solar production and moderate energy use. However, a few factors can influence whether you’ll still see an electricity bill:

  • Higher Energy Use or Low Sunlight: If your energy use exceeds what your system can generate and store, or if there are prolonged periods of low sunlight, you may still need to draw from the grid.
  • Daily Supply Charges: Most electricity retailers include a daily supply charge on your bill, even if you don’t use any grid power. While batteries help reduce energy usage costs, this fixed charge may still appear.
  • Backup Use During Extended Power Outages: For homes with backup battery systems, extended power outages may require additional energy from the grid if solar and battery storage alone aren’t enough.

 

Maximising Savings with Time-of-Use Tariffs

With a battery, homeowners on a time-of-use tariff can charge their battery during off-peak times (when rates are lower) and discharge it during peak times to avoid high electricity prices. This approach can maximise your bill savings, particularly in areas where electricity costs vary based on the time of day.

 

By investing in a quality solar and battery system, Cairns homeowners can achieve significant, long-term savings on their energy bills and gain control over their energy use. To find out more about reducing your electricity costs with solar and battery storage, contact Hielscher Electrical today.

13kWh Solar Battery

Why is a 13kWh Home Solar Battery so Popular in Cairns?

The 13kWh solar battery has become a top choice for Cairns homeowners looking to increase their energy savings and reduce their reliance on grid power. This battery size is ideal for capturing and storing the abundant solar energy produced in Cairns, allowing households to enjoy clean, cost-effective power even after the sun goes down.

 

Key Reasons for the Popularity of a 13kWh Battery in Cairns

 

  1. Optimises Solar Self-Consumption
    In Cairns, daytime solar generation is often high, and a 13kWh battery provides the capacity needed to store excess energy generated during the day. Instead of exporting surplus solar power to the grid at low rates (around 5 cents per kWh), homeowners can store it for use during the evening when grid electricity rates can reach up to 40 cents per kWh. This setup maximises savings by enabling households to use more of their own solar power.

  2. Reduces Reliance on Grid Power
    With a 13kWh battery, homeowners can store enough energy to cover a significant portion of their night-time electricity needs. This is particularly valuable for homes that use around 30% of their energy during the day and 70% at night. By increasing self-consumption, the battery reduces the need to draw expensive power from the grid during peak evening hours, helping to keep electricity bills low.

  3. Ideal for Medium-Sized Homes
    A 13kWh battery is well-suited for medium-sized homes with a solar system in the range of 5-6kW. This combination balances energy generation and storage capacity, ensuring that most of the solar power produced by the system is used efficiently to power the home. For typical Cairns households, this setup provides reliable coverage for evening and night-time usage, making the battery a practical and cost-effective choice.

  4. Significant Annual Savings
    By using stored solar energy during peak periods, homeowners can save on the higher electricity rates charged at night. For example, powering a home’s night-time use with a 13kWh battery could save up to $5.20 per day, adding up to nearly $1,900 in annual savings. This makes a 13kWh battery an attractive investment for those seeking to offset rising energy costs and achieve long-term savings.

  5. Perfect for Cairns’ Sunny Climate
    Cairns’ high solar exposure means homes can generate substantial excess energy daily. A 13kWh battery ensures this energy is captured and stored efficiently, so households can continue to enjoy solar-powered energy even during the evening. For homeowners looking to make the most of Cairns’ sunshine, a 13kWh battery offers a balanced capacity that fits seamlessly into a home’s energy needs.

 

A 13kWh battery is an excellent option for Cairns residents aiming to boost their energy independence, maximise savings, and take advantage of the region’s sunny climate.

At Hielscher Electrical, we take pride in offering only the best solar panels and inverters available. Our approach to selecting these products is rooted in rigorous testing and real-world experience, ensuring that our customers receive systems that are not only high-performing but also reliable for the long term.

 

How We Choose The Best Solar Panels And Inverters

In the early days of my journey in the solar industry, I quickly realized that the “best” solar products were often those with the most aggressive marketing, not necessarily the highest quality. To cut through the noise, I began purchasing and testing solar products myself, conducting real-world evaluations on my own warehouse roof. This hands-on approach led me to gain invaluable insights directly from the source, visiting solar panel and inverter factories, and building relationships with engineers and other installers across Australia.

 

Key Learnings About Solar Panels and Inverters

Here’s what I’ve learned over the years:

 

  1. Don’t Judge by Price Alone: A higher price tag doesn’t always mean better quality. I evaluate each container of solar panels based on build quality, long-term performance, and the manufacturer’s reputation for honoring warranties. This ensures that the panels we install are consistent in their reliability and efficiency.
  2. Not All Inverters Are Equal: Through extensive experience—installing over 5,000 Fronius inverters, 130 SolarEdge systems, and 171 Sungrow inverters—I’ve observed that Fronius inverters are the most reliable, with far fewer failures compared to others. Even the best inverters, like Fronius, can occasionally fail, which is why strong after-sales support is crucial.

All our solar packages feature Tier 1 solar panels, sourced from the top 5 solar manufacturers globally. These panels are recognized for their high quality, excellent performance warranties, and their widespread use in major solar installations worldwide. Our selection process includes:

 

  • Visual Inspections: We thoroughly inspect the surface, frame, junction box, and cables of each panel to ensure there are no defects that could impact performance.
  • Performance Testing: We conduct Open-Circuit Voltage and Short-Circuit Current tests to measure each panel’s output and verify it meets expected standards.
  • Environmental Considerations: We factor in irradiance levels, temperature effects, and potential shading or dirt accumulation to ensure the panels will perform optimally under real-world conditions.

 

Inverters

For inverters, we rely on Fronius as our top choice due to its proven reliability and excellent support. We also offer Sungrow and SolarEdge inverters, though we recommend these based on specific needs and circumstances.

 

The Impact of Shade and Dirt

We also consider the impact of shade and dirt on solar panel efficiency. Shade from nearby trees or buildings can significantly reduce energy output, so we conduct a thorough shade analysis as part of our site assessment. Dirt and debris can also affect performance, which is why we advise regular cleaning and maintenance according to warranty guidelines to keep your panels operating at peak efficiency.

We’ve built strong partnerships with some of the most reputable solar brands in the industry. This ensures that every component of your solar system—from panels to inverters to mounting gear—is of the highest quality.
