Do I need a Solar Battery in 2019?
Updated: Apr 24, 2019
If you have decided to use solar to generate electricity in your home, you've likely heard about solar batteries. Battery systems for solar energy are still a highly debated topic.
Whether solar batteries are worth the cost is a question that we at Econnect Solar get asked more and more. There are opposing views out there on whether solar batteries are worth it or not.
This is why we decided to give you our expert advice as accredited battery installers. This will help you to make a more informed decision.
1. What is a Solar Battery?
As you might already know, solar panels collect solar energy which is then converted into electricity via your inverter. Any excess not used by your household is sent back to the grid in return for a discount on your power bill — a feed-in tariff. Some solar panel systems are not battery compatible. But you can buy hybrid systems that have batteries or are battery ready. At Econnect Solar, all of the systems we install are battery compatible.
The batteries store energy for you to use at a later time or to be sent back into the grid at a time that capitalises on energy prices.
1. Costs of a Solar Battery
First of all, installing battery storage for your solar system will at least double the price of the system. The list below gives you an estimate of how much a quality battery system will cost you.
Generic Costs of Quality Battery Systems:
3.3kW: $5,500 – $6,500
4.8kW: $6,000 – $6,800
6.5kW: $6,500– $7,500
9.8kW: $8,500 – $10,000
13kW: $10,000 – $14,000
This is just a basic guide to provide you with a price range for quality battery storage. If you’d like to get a custom assessment of your home for a solar energy system, simply leave us your details and one of our experienced solar consultants will get in touch with you.
2. The Payback Period
A typical payback period of a solar battery is about 10 years. Comparing this with a solar system without a battery, a system has a typical payback of around 4-6 years and will last about 25 years.
3. Does it make sense to buy a Battery System now?
Don’t buy a battery now. It makes sense to wait 2-5 years for battery costs to come down before investing in energy storage. You shouldn’t wait for battery prices to decrease before buying a solar system, because this means that the solar rebate will be lower since it is in the process of being phased out. If you buy a system now, your electricity bills will immediately reduce. In a few years you can simply add a battery to your existing system for even greater cost savings.
