One of the reasons why some people are still hesitant to use off-grid solar power is the availability and reliability. While the Australian government is offering discounts and encouraging people to use renewable energy, the problem of low supply during an overcast day remains. That’s the reason why solar battery storage systems have become more important.
Future Solar Battery Storage Solutions
Simply put, battery storage systems will ensure your home has an uninterrupted power supply so even if the sun is out, you won’t have to go back to the grid for electricity. Because it is so important, companies are studying different methods and developing new technologies to make battery backups more affordable.
While there are a lot of technological issues that need to be addressed, many companies are already providing battery backup solar products. In fact there are now companies in Australia and the United States that are testing products and might commercially release them in a couple of years.
Lithium-ion and Zinc-Air Technologies
The majority of battery solutions for off-grid solar systems today use lithium-ion technology, but it has its limitations and is quite expensive. For this reason many experts are looking at zinc-air technology because it has greater energy capacity and is potentially more economical to manufacture and use.
While zinc-air is promising, there are certain problems that need to be addressed before it can be used as a battery. One of the biggest concerns is the difficulty in controlling the reactions that occur following charges and discharges, but these may be overcome as technology improves.
Available Solar Storage Systems
There are solar battery storage systems available that offer anywhere from 150 kW to 10 MW, and while aimed at commercial and industrial establishments can pave the way for more affordable residential applications. Exactly how this can work out is still being studied although it may come in the form of incentives and government subsidies.

The development of affordable battery storage solutions is now on-going, and while some scientists are sceptical about the situation, other experts are not. One of the keys to off-grid solar storage solutions is the reduction of the storage cost of lithium ion batteries. While lithium-ion is more expensive than lead, the price should drop as the technology gets cheaper.
According to expert Margarete Wohlfahrt-Mehrens of the Centre for Solar Energy and Hydrogen Research Baden-Württemberg, the cost of solar battery storage should drop by half the next few years, making them more affordable for homes. The reasons for the coming price drop include new innovations, mass production and development of better technologies. Currently, lithium-ion uses lithium metal for the cathode and graphite for anode, but newer methods should be available in the future and make more affordable storage solutions.
Lithium-ion anodes and cathodes are produced using suspensions with lithium and carbon as the substance electrolytes. By using larger sheets, the manufacturing process will accelerate. In addition, future battery backup solar solutions will use different types of anodes that will recharge faster and can handle more load cycles.
