Solar Battery Storage FAQs

Adding solar battery storage to your solar power system will make your energy generation more efficient and will help you be more self-sufficient. You do not just get to use free energy all day when the sun is out, but the battery storage system will also allow you to have solar power during the night, on rainy days, during power outages or anytime that direct sunlight is not available.

Australia is one of the leading countries that is pushing for renewable and sustainable energy. As solar power is becoming highly encouraged, we have come up with solar battery FAQs and home battery system FAQs to help you get a better understanding of the setup, benefits, government assistance, and other topics related to solar battery storage.

How Long do Solar Panel Batteries Last?

On average, a regular solar battery lasts between 5 to 15 years depending on how well you maintain and take care of them. Other factors that affect the lifespan of the batteries are:

  • The Brand or Manufacturer. A Tesla Powerwall has a 10-year limited warranty although it lasts for 5 or more years beyond its warranty without a rapid decline in its storage capacity. The Tesla Powerwall lifespan has proven to be longer and more reliable than other brands.
  • Proper Maintenance. Although solar batteries do not have high maintenance requirements, units that are properly cared for and maintained last longer.
  • Temperature. Extreme temperatures have a significant effect on the lifespan of solar batteries. Protect your solar batteries from freezing or sweltering temperatures to increase its lifespan. Solar batteries with a temperature moderator are more effective and will last longer. Tesla Powerwalls are equipped with temperature moderator so when it drops below -1C or go beyond 32C, your battery will not be stressed.
How Do Solar Batteries Work?

Solar batteries allow you to store excess solar electricity at your home or send it back to the grid in exchange for a small rebate. When your solar panels generate more energy than you are actually using for the day, the excess is used to charge the solar batteries, working as storage so you can use this energy at a later time. The higher the capacity of your batteries, the more solar energy you can store.

What Is A Tesla Powerwall?

A Tesla Powerwall is a stationary rechargeable lithium-ion battery that is considered the most reliable form of home energy storage today. It stores electricity from solar energy for self-consumption, load shifting, off-the-grid use and backup power. It is available on-demand, can sufficiently power your home, can be used during the night, or can be used as back up power during power outages and emergencies. The Tesla Powerwall has a built-in battery inverter which makes it compact and easy to integrate into your home.

How Does A Tesla Powerwall Work?

The Tesla Powerwall system is made up of at least one Powerwall battery and one backup Gateway. They work together in gathering, storing, managing, and monitoring the energy levels. It is optimised for daily cyclings like load shifting, among other functions.

The Powerwall is charged through solar energy during the day. It then stores the solar energy into the Powerwall energy storage unit until it is needed for consumption. It is usually during the night when solar energy cannot be collected, that the stored energy is used. It is also used for emergencies like power outages or when the grid is offline.

How Many Solar Panels Do You Need To Charge A Solar Battery?

The first thing you should ask is how much electricity do you use on an average day and night? As a rule of thumb, one solar panel can charge a 12-Volt battery. The number of solar panels you will need depends on how much electricity you consume, your roof space and your budget.

  • A small household of 1-2 people will need an average of around 2 kW or 8 solar panels.
  • A medium household of 2-3 people will need an average of around 4 kW or 14 solar panels.
  • A large household of 4 or more might need more than 5 kW or over 24 solar panels.
How Many Solar Panels do You Need to Charge a Tesla Powerwall?

On average, a solar panel is about 200W – 400W. Assuming a panel of 300W rating, you will need around 18 solar panels to charge your Tesla Powerwall in a single day. This should be enough for your home backup. You can always add more panels for better storage capacity as your need for more energy storage and electricity consumption increase.

Since buying a newly built house in Hervey Bay we have used grc to install our solar panels, air conditioners, to increase the number of TV connections and many more power points. We have found that not only was their service top shelf but the guys who did the work were exceptionally helpful and very polite. In summing up it is easy to see why this company is so successful when you look at the people you deal with from Gary and Christabelle down to the young fella who takes his boots off before walking in the door. I would highly recommend this company.

Gary and his team came highly recommend to us when we moved to Hervey Bay a couple of years ago, we had quite a lot of electrical jobs to be done in home and around the property, from running power to my shed which was about 30 metres from the house connect the power up to the new pool pump and water feature, installation of three split air conditioning systems and multiple Big Screen TVs around the house which they happily mounted to the walls, added extra power points where they were needed, and the big ticketed item of 36 micro inverted solar panels, we were more than impressed with Gary and his team of tradesmen, I have had to call Gary a couple of time just for advice and nothing is ever a problem for him he always responds promptly and his happy disposition makes him so very easy to deal with. Absolutely no hesitation in recommending Gary and GCR ELECTRICAL for all you electrical and solar needs.

We have had a 6.6 kw system with a Fronius inverter and Winaiko panels installed in Feb 2020. After tackling the minefield of solar retailers, thankfully we were recommended to talk to Gary and Christabelle. The entire process was handled professionally from the initial contact when we lived interstate through to the very tidy install and after sales service. Gary’s advice on what we needed was superb, I had so many questions! We had no idea of our power use as the house had been a rental, but early numbers show we should have reduced our bills to approx $0 a year so the system will have paid for itself in around 4 years. Could not recommend GCR enough. Thanks Guys, A and H 😁

Gary, Christabelle and the rest of the GCR team were awesome. They were great communicators, very easy to deal with and honest about the best options for my place. Unfortunately, due to my local transformer (Kawungan) being 130% over capacity Ergon won’t pay me a feed in tariff due to their poor infrastructure and lack of planning for a decentralised energy system. This wasn’t GCR’s fault but disappointing for the community given my neighbours will also be in the same position when they go to install solar unless Ergon upgrades their infrastructure. GCR 5/5. Ergon 1/5.

Gary and his team were extremely professional and helpful. Price was on par with other major retailers, and the gear is the same / comparative too. I got quotes from 3 retailers, and for the gear we got GCR was the best in price.Installation - the team was on time, efficient, and thoughtful. To spend the hottest part of the day on and in the roof and then take time to explain it all afterwards was great.Highly recommend, I am normally skeptical of small businesses with low reviews, but GCR’s has definitely earned the 5 star rating on here.

Recently had GCR Electrical Systems install a 6.6kw system on my property in Urraween. From quoting, booking in of the job, installation and quality of works the service was exceptional and beyond expectations.The whole operation from start to finish was professional, all of the men who installed the system were careful with my home and also took care to clean up completely after the job. Gary's advice regarding the solar was second to none and he was able to answer all of my questions. It's been a great experience knowing how everything works and functions in regard to the system installed!I wouldn't hesitate to use GSR again when needed! These guys are pros!

Gary and his team have just completed fitting a new 6KW SOLAR system and a 6.5KW MHI A/C unit to to my rental properties in Urangan. He provided very competitive pricing. Gary understands the latest electrical regulations and compliance. His workmanship is neat and top quality which is important when installing roof mounted SOLAR panels. All work was carried out in a polite professional manner, an excellent quality job without fault.

Rowan, Your team are both very efficient and courteous, upon arriving they have measured and checked the shadowing effect of the neighbouring trees and have discussed; strings for the inverter, positioning of the banks of panels, shadowing of the panels and the effect for summer and winter. Thank you and the boys for the installation, we are very happy with you and your team for a professional attitude to having the Solar Energy System installed
