Solar Battery Storage

Solar Battery Storage allows homeowners to do many things, such as:

  • Store solar energy produced during the day and use it at night
  • Provide your home with backup power in case of a grid outage
  • Manage time-of-use tariffs (TOU) to buy energy at cheap off-peak rates
  • Enjoy a premium rate for the surplus energy you sell back to the grid

While it is possible for many homeowners to completely disconnect from the grid, we advise against doing so. If you were to be completely off-grid, you would not only require additional components which can prove rather expensive, but you’d also find yourself without backup power if one of the components fails. The existing grid is a very cost-effective means of meeting your household’s peak power demands, plus you may also be able to take advantage of the premium rates that retailers frequently offer if you’re able to sell power back to the grid at peak times.

The Benefits of Solar Battery Storage

Optimise Your Solar Power

There’s a huge gap between what homeowners pay for energy and what they receive when they sell the excess solar power produced during the day back to the grid. With the arrival of energy storage systems, homeowners will be empowered to store the excess energy they produce from their existing solar system and use it at peak times when energy costs are at their highest. This increase in solar energy self-consumption significantly improves the returns of investing in a solar power system.

Slash Energy Costs with Peak Shaving

Energy providers’ time-of-use tariffs charge a premium for energy used during peak times while charging lower rates at off-peak times. With an investment in a home energy storage system, homeowners will be able to slash their energy costs by purchasing and storing energy when it’s cheap and using that power at peak times when they would otherwise be charged a premium.

Backup Power Delivered

Energy storage systems can deliver backup power in the absence of grid energy so that essential loads, such as fridges, lights and medical equipment, can still run in the event of an outage. This is ideal for households in remote areas or areas in which power outages are common.

Solar Batteries Perth – The Financial Benefits

At the present point in time, home battery systems are still not as cost-effective as solar power, solar hot water and other available technologies. It’s unlikely that you will be able to recuperate the financial outlay involved in a practical timeframe or before the warranty period expires.

A battery storage system capable of storing 6 kWh of excess solar production over the course of the day only delivers energy savings of around $400 annually. And that’s provided every battery is used to capacity on a daily basis, which is quite unlikely, plus there’s the reduction in storage capacity to take into account which occurs quicker in batteries than it does in solar panels.

What’s more, it’s also a sizeable investment – it adds $8000-$10,000 to the cost of a new solar power system or $9000-$11,000 to retrofit your home. Given the minimal savings, the reduction in storage capacity and the sizeable outlay involved, a home battery system simply isn’t a savvy investment, at least not at the moment, though having said that, battery prices themselves are dropping rapidly.

Some home battery systems enable you to sell stored energy to the grid during peak times, which could see you enjoying premium rates. However, you need to produce more energy than you consume in order to do this, which may mean you need to power down your home appliances.

Energy Storage System Types

There are three main types of home storage systems – AC Coupled, DC Coupled and Hybrid. While retrofitting is possible and each offers benefits and drawbacks, we encourage those purchasing a new system to opt for a hybrid inverter, for direct battery connection now or in the future. Speak to one of our consultants to decide which system best meets your needs.

For a more precise estimate, get in touch with Solar Repairs Perth, and we’ll help guide you through the process.

A DC (Direct Current) coupled battery is connected directly to the solar panels via a charge controller. It converts the DC power generated by the solar panels into AC (Alternating Current) for home use and recharges the battery with DC power. This system is efficient and often less complex to install, especially in new solar installations.

An AC (Alternating Current) coupled battery system is connected to your solar system’s inverter and stores the AC power that’s already been converted by the solar inverter. This type of system is commonly used when retrofitting a battery to an existing solar system, as it can be easily integrated without disrupting the current solar power setup.

Yes, one of the significant benefits of a solar panel system with batteries is the ability to provide backup power during power outages. If the grid goes down, a solar power system with battery storage can isolate from the grid and continue to supply power to your home, ensuring that your essential devices remain operational.

Solar panels themselves can still generate power during a power outage. However, for safety reasons, most solar power systems are designed to automatically shut down when the grid goes offline to prevent potentially dangerous “islanding.” This is where a solar battery comes into play – it can provide stored power during an outage, allowing your solar power system to continue operating independently of the grid.

The lifespan of a solar battery can range significantly, typically between 5 to 15 years, depending on the type of battery, its capacity, and usage.
