For many people, the best way to gain the full benefits of a solar panel energy system is with a battery. Every state and every energy retailer is different, but there’s one thing that always remains the same - choosing the right battery is seriously important for getting the most out of your solar investment.

How do solar batteries work?

Solar batteries work by storing the excess energy that’s produced through your solar panels during the day so that you can use it at night. This can save you money on your energy bills, as it’s much more cost-effective than just selling the energy back to your retailer at a cheap day rate. Further, without a battery you still need to buy a lot of grid power at night, so you’re not protected as these rates keep going up and up. Why not save your energy for yourself and boost your energy independence and sustainability?

However, some providers state that their solar systems are ‘battery ready’. Technically, any solar panel system can accommodate a battery, but only those with a hybrid inverter (which we offer at ShineHub) will be able to take on a battery without the additional cost of adding a battery inverter.

Considerations for choosing the right solar panel

Knowing your property, region’s climate and quality assurance basics are key when shopping around for a solar panel.

Lifespan

Assuming that batteries cycle once/day (as they charge during the day and are used at night), there are 3,650 cycles in a 10 year period. Researching batteries that are rated to at least 3,650 cycles is a good place to start but some are rated up to 6,000-8,000 cycles.

Chemistry

Lithium Ion Phosphate batteries are often the preferred chemistry, withstanding tough conditions and offering reliability. It’s worth knowing considering the geography of where you live, especially as other chemistries tend to be a bit smaller and might not last as long against certain environmental pressures. You can read all about battery chemistry types here.

Size

The size of the battery you choose will be a reflection of how much space you have to work with. If you’re short on space, you’ll be limited to smaller battery but if you have the space to accommodate a larger battery, you’ll have an advantage in terms of performance. For a family sized battery, the smaller batteries are not much bigger than the size of a carry-on suitcase, where the larger batteries are 2-3 times larger than that.

Location

Across the range of solutions, batteries will either be suitable for indoor installation (typically in a garage or shed) or rated for outdoor installation (suitable for anywhere other than in direct sunlight). Choosing to install outdoors will likely involve finding an accessible spot on a verandah, deck, or on an outside wall under an awning.

Solar Batteries Make Good Financial Sense

A recent study from the University of South Australia concluded that yes, they are a very financially viable option for residents in South Australia. The crazy thing is this study was conducted on batteries that had an average price of $9,000… whereas at ShineHub, our buying power and virtual power plant offerings make amazing solar batteries affordable, with the average price of one of our batteries starting at just $2,999 or $1/day! (as part of the South Australia Home Battery Program).

If $9,000 is considered a good financial investment, then a battery at $2,999 is an absolute steal.

We use systems comprised of panels + hybrid inverters + batteries (the recommended approach). Our panels come with a 25-year warranty and our batteries with a 10-year warranty, so there will be no unexpected costs coming your way.
