How Much Do Solar Batteries Cost?

They Might Be Cheaper Than You Think!

enphase-ac-battery-on-the-wallSolaray are installing battery storage systems with an increasing number of solar systems as households begin to see the benefit of storing excess solar power to use in the evening. The first Enphase Energy Management Systems in Australia have now been installed, and we have seen strong interest in the Tesla Powerwall.

Solar Batteries are compatible with any existing solar system, and are connected directly to your meter board where we install a system hub that connects your house to the cloud for advanced system monitoring and management. Solaray Energy Management Systems come with home automation capabilities built-in, and they are fully compatible with micro-grids once they come online over the next few years.

One of the most common questions we get at this early stage is: “is solar storage worth the money?”

Our answer is to throw a question back at you: “how much would you be prepared to spend to save, say, $1000 per year? Your answer to this determines when you are ready to buy Energy Storage…

20160909_112337(Importantly, this is not actually the way we determine the value of batteries, but it is a good introduction.)

Let’s say you install 5kWh of Energy Storage with an estimated lifetime of 10 years (3,500 cycles).

Let us also assume you will use all of that 5kWh each and every day.

Lastly, let’s assume you are paying 30c per kWh for your power today.

Therefore, your 5kWh of storage would be expected to save $1.50 per day (30c x 5kWh) or $547.50 per year. The batteries themselves should last well in excess of 10 years – although there capacity will slowly diminish over time.

If you were happy to accept that you would get your money back in say 7 years, you would therefore expect to pay around $3800 for that 5kW of storage. If you needed to get your money back in 5 years, it would be around $2700, and $5,500 for 10 years, and so on.

The cost of batteries start at around $2,000 for smaller units and can be as much as $12,000 or more for the larger units. Because battery systems need to be accurately sized up to match your requirements we encourage you to make an enquiry. A member of Solaray Storage Team can go through your options and present you with a full quote for installation.

How to size up a Solar Energy Storage System?

In reality, we use rather complicated spreadsheets and analysis to work out the best size storage system for you and to make a fairly accurate estimate of your savings.

Naturally, we also take into account the size and performance of your current or future solar system which has a major impact on the value you get from your storage system.

Be one of the first to get the Enphase Energy Management System!

We are excited to announce the release of the highly anticipated Enphase AC Battery to be used in conjunction with the Envoy-S Metered.

Enphase Micro Inverters revolutionised residential solar systems. Now Solaray are ready to revolutionise Australia’s energy sector as we install some of the first Enphase Energy Management Systems in the world!

Micro Inverter technology allows each panel in a solar system to work independently from the other panels, ensuring maximum output of clean renewable energy for your household or business.

The innovative Enphase Energy Management System combines energy generation from your solar system with battery storage, control, and management into one complete solution. It’s smarter and more connected than ever before.

The response to the new Enphase Power Storage System has been incredible! We knew that an interest in battery storage was going to explode this year, but we have seen an even greater demand than what we expected. In fact Enphase have just announced that they will be doubling production in Australia.

The Enphase Energy Management System is unlike anything else currently available because of its compatibility. Enphase Batteries are connected directly to the meter board, where we install a control hub that manages power consumption and storage in the home. This allows the Enphase power storage system to be compatible with any existing solar system. This is in stark contrast to other battery systems that typically connect directly to an expensive hybrid solar inverter and have limited compatibility.

The system itself has been designed to be modular, expandable, easily installed and can be tailored to each customer’s usage profile. A household or business will be able to monitor their usage, solar generation and peak times, and install more battery capacity knowing that it will pay for itself in the quickest possible time.

We are very excited about the possibilities that the Enphase Energy Management System will provide for households and businesses and believe the Enphase product will be a market leader.
