A solar battery system allows you to take full advantage of the solar energy produced by your rooftop solar panels. Having a backup solar battery bank makes you self-sufficient, reduces your carbon output and saves you from soaring power bills, especially during peak periods.

So How Does a Solar Battery Work?

Typically, in a solar power system, the solar panels generate and supply power to your appliances during the day. And it exports the excess energy generated during the day to the grid.

When there is a shortfall, usually during early mornings, evenings, nights and in cloudy weather, energy is imported from the grid with the help of an inverter to meet the energy requirements. Moreover, whenever there is a grid blackout, the inverter turns off, and most home solar power systems also shut down.

But by installing a solar battery to your existing solar power system or a new solar panel and solar battery system together, you eliminate the need for importing electricity from the grid. The right solar power system with enough solar batteries makes you less dependent on the grid by preventing importing electricity from the grid.

So, let’s see how a solar battery actually works. If you have solar batteries, the excess energy generated during the day is not fed into the grid but is used to charge the solar battery. Some solar batteries can also charge from the grid during off-peak times, typically overnight (when electricity prices are the cheapest).

The solar batteries then store the surplus energy produced by the solar panels for later use. This energy is also used whenever there is a surplus need for energy at home, more than the energy generated from your solar panels. Thus, solar battery bank systems can power your household appliances without importing power from the grid. Lithium-ion batteries are the best solar batteries available on the market today. They have a longer lifespan, occupy less space and are easy to maintain.

What Happens When Solar Batteries Are Full?

You may wonder what happens when the solar batteries are in full charge because a constantly overcharged system affects the battery life. Not to worry, when the batteries become fully charged up, the excess energy is fed back to the grid.

And in the case of off-grid solar systems, you have battery monitoring systems and charge controllers that protect the batteries by redirecting and managing the energy flow. Some batteries and inverters also have displays that indicate the battery status. However, if your batteries become regularly full, you may need to purchase additional batteries for storage, or an accredited solar installer will be able to help you with that.

How To Use Solar Batteries Effectively?

Many households have typical energy consumption during evenings and nights. With a bigger battery bank system, you could efficiently manage all your energy needs without relying on the grid.

One way to effectively use solar batteries is by running appliances with large electrical loads, such as washing machines, dishwashers, and hot water service, during the day instead of at night. This prevents solar batteries from depleting completely and improves their life.

Having the right system is crucial to make the most use of your solar batteries and solar panel system. With the advancements in solar technology, we have various solar energy storage options available today.

Solar batteries store power generated from the solar panels— and use them to power appliances during blackouts, at night or when the sun is not shining. Installing the right solar battery to your solar power system help reduce power bills and grid dependency. So, here’s what you need to look for when choosing a solar battery.

1. Battery Size

Solar batteries are available in a range of sizes. A solar battery’s size determines its capacity and how long the battery can hold power. It is typically expressed in kWh.

Choosing the right size is critical as both undersized and oversized solar battery systems can affect the overall performance and lifespan of the solar power system. That’s why reaching out to an accredited solar installer is crucial for solar battery installations.

An accredited solar installer will choose an appropriate solar battery size and the number of batteries you need for your solar power system, depending on your energy requirements. For a better understanding, here is an easy example. If your energy consumption is approximately 1kW per hour, a 10kW solar battery may last around 9 to 12 hours.

2. Energy Capacity

A solar battery’s energy capacity is the amount of energy the battery can store and supply to your appliances when in need. It is measured in kWh. The higher the energy capacity, the higher the size of the battery, which means it can hold power for a long time. Today most solar battery systems deliver a continuous power output of 5kW.

3. Power Rating

The power rating of a solar battery indicates how many kilowatts (kW) of power the battery can deliver at once. To be precise, it tells you how many appliances your solar battery can power at once and which those appliances are. Solar batteries also come with two different power ratings: a continuous power rating and a 5-minute or instantaneous power rating.

The instantaneous power rating indicates the amount of power (usually large power) delivered in short bursts. It is suitable for appliances that require a large amount of power to turn on and then run on lower power.

4. Roundtrip Efficiency

Roundtrip efficiency is the percentage of electricity put into storage that is used later. In other words, the roundtrip efficiency of a solar battery tells you how many units of electricity you get from a battery for every unit of electricity you put into it. And this is associated with loss. It’s because no battery is 100% efficient, and there is always going to be some loss. The higher the roundtrip efficiency, the more efficient the solar power system and the less energy lost during storage. So, you need to choose a solar battery with the highest roundtrip efficiency. Typically, an 80% roundtrip efficiency is expected in solar energy storage systems.

5. Battery Lifetime

Never ignore to check for the battery lifetime. Battery lifetime means how long the battery can last, often measured in terms of expected years of operation, expected throughput and expected cycles. For instance, solar lithium-ion batteries have a long lifespan of 15-20 years with a super high cycle life compared to lead-acid batteries. Lithium-ion batteries also do not require frequent maintenance and replacements.

6. Safety

There are many safety standards a solar battery must meet to be certified for installation at home or business. So, you must check if the solar battery you are looking for meets all the safety standards. At Always Energy, we provide only the best solar battery and solar panel systems that meet all the safety standards and ensure high performance.

Though solar panels do not need direct sunlight to make solar energy, they need direct sunlight for maximum efficiency. It is best if your solar panels receive direct sunlight for at least 4 hours a day. And Port Macquarie affords this advantage by receiving approximately 4.8 hours of peak sunlight per day, making it a great place for both residential and commercial solar power installations.

Roughly around 21% of households in Port Macquarie have already installed rooftop solar panels. Many businesses are also fondly investing in solar for its benefits. So, solar energy is in high demand, and our team has been working on multiple residential and commercial solar installation projects throughout Port Macquarie.

Here are some of our latest solar system installations in Port Macquarie.
