Solar Battery Storage Systems

With the West Australian reporting that WA is set to record the second highest electricity prices in Australia, more and more people are starting to ask questions about Solar Battery Storage Systems.

Battery Storage Systems are now available and bring some great benefits, such as:

Significant savings on your electricity bills
Solar Battery Systems can help you save even more money on your electricity bills. Instead of your system exporting excess solar energy to the grid for a small feed-in tariff, your solar battery will store any excess electricity, allowing you to use it later in the evening, when your solar PV system is not generating any electricity. 

Reduced reliance on the grid
Installing a battery system to your home or business will lessen the amount of energy you need to buy from the grid.

Backup Power 
Battery Storage Systems can be set up to provide you with back up power in the event of an outage.

How Solar Battery Storage Works

Solar battery storage works by storing excess solar production during the day for use at night. This is more cost effective than selling it back to your retailer during the day at a cheaper rate. On a time of use tariff, you can also purchase grid power during cheaper periods, reducing how much you purchase during peak periods. Battery systems can also be configured to provide power in an outage. There are a few different types of battery storage systems available. To find out which system would best fit your needs please contact us, and speak to one of our friendly consultants!

Is it worth purchasing a battery system now?

There are important aspects to consider when contemplating investing in solar battery storage with a new PV System, or a retrofit for your existing PV System.  You want to maximise the benefits that will assist with a return on the investment, but importantly be able to meet your electricity requirements at night. 

While Battery Systems are becoming more cost effective, they are a big investment. Battery storage prices are not yet at the level where it makes economic sense for the average Australian to add batteries to their home. You are looking at around a 15 year payback on batteries with an expected lifespan of 10 years.

However not everyone cares about payback when buying batteries. Some people are prepared to spend the money to get their grid imports as low as possible.

The first generation of Solar Batteries has arrived with many manufacturers in the process of bringing better innovations at a less cost to market.  2018 will be the year these innovations will offer more choice,at reasonable prices,  in the meantime we can assist you to retrofit or include compatible systems available today. 

Are there rebates (STC) applicable to Solar Batteries?

No not today. This only applies to the PV panels installed. 

Can I retrofit a battery storage system?

Yes, in most cases you can retrofit to an existing system.  There are a number of installation requirements to consider which generally involve adding a battery inverter device to manage AC current, whilst your solar inverter converts DC to AC current.  An assessment of the current inverter and panels configurations to ensure sufficient power can be generated to store in the battery for overnight use would be helpful.

Is there a battery ready PV solar system?

Many people ask if this can be available in their current purchase of a PV system. Most PV systems are battery ready, however you need to consider what needs to be added to the system when your contemplating adding batteries, installing a hybrid inverter with high efficiency solar panels can help this process. Compatibility of battery systems are very important assessments to be made.  

Can I purchase a battery back up system today with my PV system?

Yes, there are a number of examples of back up battery ready PV systems today which continue to innovate and work towards cost effective products, Termico Solar offer several for you to consider. 

Do I require approval to connect a battery?

Yes, talk to your energy supplier to undertake that process or Termico can assist you with that. 

Will a solar battery storage system save me money?

Yes, after installation of an appropriate sized device to meet your nighttime use restricting the need of import of power from the grid. 

If I install a solar battery system does it effect my feed in tariff?

No, only to the extent you will not be exporting to the grid that much it now feeds to the battery. 

What are the costs to purchase and install a solar battery system?

These will vary widely in each home. Based on the size system, Installation requirements and in the case of retrofits, will the current system be able to be incorporated or not. There are no straight answers without a complete assessment.  

If I decide to wait for affordable solar batteries should I install PV solar now?

Yes. Saving money on your power bills by installing solar PV has never been better as power prices continue to rise. You do need to consider the type of solar panels to use now. We recommend high efficiency panels like SunPower or Q Cells Peak that produce a higher yield able to charge the battery.
