Will Solar Batteries Get Cheaper – A Conversation with Experts

The Future of Solar Battery Prices: A Look Ahead

The topic on everyone’s mind at the Smart Energy conference was the future of battery storage. As demand for renewable energy solutions grows, so does the curiosity about the cost of solar batteries. Are they becoming more affordable? When can we expect significant price drops?

Current State of Battery Adoption

According to Markus, a representative at the conference, interest in solar battery storage is on the rise. New buildings are being equipped with solar and battery solutions right from the start, and homeowners are financing these installations through their mortgages. With the decreasing price of energy export and increasing energy costs, more customers are considering batteries as a viable option.

Battery Market Trends

The floor at the Smart Energy Council conference in 2023 showcased a growing number of battery products entering the market. With Chris Bowen’s backing for battery manufacturing in Australia, the demand for batteries is expected to soar even higher.

Leo, who has been in the battery industry for over 10 years, shared insights into the durability and potential pitfalls of lithium-ion batteries. Over-discharging and leaving solar batteries unused for extended periods can lead to their degradation or even failure.

Why Aren’t Solar Battery Prices Dropping?

Contrary to the decreasing prices seen in solar panels and other renewable technologies, battery prices have remained relatively stable. Several factors contribute to this:

  1. Supply Chain Challenges: The production of batteries relies on a complex supply chain, which can be affected by disruptions.
  2. Demand from Electric Vehicles (EVs): Most battery cells are consumed by electric vehicles, leaving a small percentage for energy storage.
  3. Rare Earth Elements: The materials used in lithium-ion batteries contain rare earth elements, which can make them more expensive.
  4. New Technologies: Sodium-ion batteries, for instance, use abundant elements like sodium and carbon, making them potentially cheaper to produce.

The Future Outlook

While immediate price drops in lithium-ion solar batteries may not be on the horizon, there’s hope on the horizon. As electric vehicles take longer than expected to reach mass adoption, an oversupply of lithium could lead to lower battery prices.

In the words of a conference attendee who visited the LG Chem factory, the fight for resources between residential and automotive batteries will be significant. If the trend continues, residential solar batteries might not become cheaper due to the high demand from the automotive sector.

However, with the recent collapse of lithium prices in 2024, there’s optimism that home storage system prices might finally see a reduction. This development is crucial for enhancing grid stability and accommodating excess solar energy produced during the day.



The journey towards affordable solar battery storage is complex, influenced by various market forces, technological advancements, and demand from different sectors. While significant price reductions may not happen overnight, incremental decreases are anticipated in the next two to three years.

As we await these changes, it’s essential to stay informed and continue supporting innovations in the energy sector. After all, more affordable solar batteries mean a more sustainable and resilient energy future for all.
