Fast tracking access to solar power for apartment dwellers with its SolShare technology, Melbourne-headquartered technology developer and manufacturer Allume Energy has released SolShare 2, featuring battery-sharing functionality and the potential to sell excess power back to the grid.
SolShare 1 is a world-first, Australian made behind-the-meter solution that sits between the solar inverter and the apartment meter, monitoring the energy requirements of each apartment in real time so that solar is directed where it is needed within the building.
The federally funded SolShare 2 delivers a 36% increase in energy-sharing capacity over SolShare 1, up from 22 kW to 30 kW, and with the new ability to pair with a battery.
“SolShare 2 has been redesigned with batteries in mind, and this is why there has been an increase in SolShare’s capacity, from 22 kW to 30 kW, along with the addition of additional hardware interfaces that support battery optimisation,” Allume Energy Head of Technical Partnerships Mio Dart told pv magazine.
“The re-design has also enabled faster assembly and commissioning. Plug and play ethernet for better uptime and enhanced monitoring. These changes effectively unlock shared solar and battery capabilities previously available only to freestanding home owners and change the value proposition of a battery for an apartment resident.”
Dart added that like SolShare, any excess solar not consumed by an apartment can be exported to the grid and where applicable, apartment residents are paid the appropriate feed-in tariff for their electricity plan.
“We are currently working to fully integrate SolShare 2 so that customers will be able to begin trading excess energy with the wholesale market, optimising their batteries to buy, sell and store energy when it is most worthwhile to do so, and get paid wholesale feed-in rates,” Dart said.
Built in Melbourne, Victoria, SolShare 1 currently supports over 10,000 apartments worldwide, which in Australia is forecast to grow by 4,300 apartments by mid-2027.
“SolShare 2 development was centred around feedback we have received from our installer network, apartment residents, owners’ corporations, social housing providers and other stakeholders, ever since the launch of SolShare 1,” Dart explained.
“In response to this feedback, our Melbourne-based product development team have worked with a range of specialised partners who bring their expertise to various aspects of SolShare 2 design. The product development lifecycle has reacted to and addressed changing market needs, such as the introduction of the Cheaper Home Batteries Program last year, in this fast-paced industry.”
Energy equity
Dart said Allume views the SolShare 2 upgrades as the next step in closing the energy equity gap between apartment residents and freestanding home owners, particularly as the Cheaper Home Batteries Program is driving a huge increase in home battery adoption.
“The expectation is with the accelerated uptake of rooftop solar and SolShare that we are seeing in Australia and worldwide today, hundreds of thousands of apartment residents – including renters – who have long been locked out of solar and batteries, will now be able to begin tapping into even more renewable energy and bigger bill savings in the next 1-2 years, up from an average of $381 per apartment per year with SolShare 1, to $750 per apartment with SolShare 2 and a battery,” Dart said.
“The new technology supports a step change in scalability at a time when we’re seeing increased growth, enabling us to keep assembly in Australia while meeting that demand.”
