• Solar batteries : Systems like Tesla Powerwall and Enphase are popular today due to the rise of solar batteries that allow homeowners to store excess solar energy for later use.
• Floating solar farms : Australia is experimenting with floating solar panels, which are placed on bodies of water that can be highly efficient due to the cooling effect of water.
• Hybrid inverters : These are becoming more common in residential solar setups because they allow for solar energy generation and storage.
• Solar thermal energy : This is increasingly being used in commercial applications, and it uses mirrors to focus sunlight onto a central point to create heat.
• Perovskite solar cells : This is an emerging technology and research into perovskite cells is ongoing. It has the potential to improve solar efficiency at a lower cost.
• Solar carports : These are solar panel arrays installed above parking areas and are becoming popular in commercial and residential setups.

Advancements in Solar Panel Efficiency and Design

Traditional silicon-based solar cells are almost at the end of their efficiency limits. Hence, researchers are turning to new materials, specifically perovskite and tandem cells. Perovskite solar cells have shown promise with high efficiency at a lower production cost and can potentially be combined with silicone to create tandem cells, which layer different materials to capture a broader spectrum of sunlight.

Currently, the CSIRO, with its first and only lab in the Southern Hemisphere, is exploring new designs and processes to increase perovskite solar cell performance, such as integrating PV for high-density commercial and residential buildings with limited roof space. They are also researching ways to make perovskite materials compatible with glass products.

These innovations are expected to improve energy conversion rates, make solar installations more productive, and reduce the space needed for panels.

Also, in the next years for solar panel advancements, thin-film solar panels using flexible solar technology will be in more demand, specifically as portable power for outdoor activities and in places where standard panels are impractical.

Unlike typical silicon PV panels, thin film panels can be applied in a much wider array of environments. Its manufacturing process is also considered more environmentally friendly due to less wastage and lower energy requirements.

Also, expect more aesthetic designs that blend seamlessly with buildings. For one, Tesla’s solar roof tiles allow homeowners to replace traditional roof materials with solar tiles that look like conventional roofing.

Another emerging technology is transparent solar glass that can be used in windows to allow buildings to generate electricity without impacting their appearance. These designs provide options for homeowners and business owners who want to install solar without the visual impact of traditional panels.

Innovations in Energy Storage

Energy storage is a vital component of solar technology, and it's set to evolve in the coming years. Lithium-ion batteries are currently dominating the market of energy storage solutions, but advances are pushing toward alternatives like Solid-State Batteries (SSBs), which provide higher energy density, improved safety, and a longer lifespan.

Altech Batteries in Perth has switched to a 60-kW sodium-chloride SSB prototype in a trial in Germany and is being monitored to see how it runs under real-world conditions. Also, Ford and BMW have announced the finalization of the installation of their “pilot production line” for SSBs, which essentially means they are ready for commercial-scale production with their production of sulphide-based SSB cells.
