Canadian startup unveils substring inverter prototypes
Daanaa has introduced its new Zodiac substring inverter, which is designed to deliver up to 42% more energy compared to traditional setups. As of February 25, 2025, this innovative prototype is available for module manufacturers to evaluate by integrating it into the backs of solar panels.
The Zodiac system comprises two main components: the Virgo module and the Pandora module. The Virgo module connects to solar cell substrings, optimizing direct current (DC), converting it to high-voltage alternating current (AC), and providing rapid shutdown functionality along with substring-level monitoring and diagnostics. Meanwhile, the Pandora module aggregates the AC power from the Virgos, producing a single AC output for the grid and serving as a communication interface with external gateways and servers.
Daanaa claims that Zodiac’s independent substring optimization can yield an average of 15% more energy in typical installations and up to 42% more energy in situations with light obstructions. By eliminating external power electronics and minimizing the number of cascaded components and connectors, the inverter not only simplifies installation but also reduces overall costs.
The company’s findings have been accepted and published by the IEEE’s Conference on Photovoltaic Specialists (PVSC). Udi Daon, CEO of Daanaa, stated, “The solar industry has long faced challenges with power losses and system complexity due to dependencies on external power electronics. Zodiac addresses these issues by embedding multiple functionalities at the substring level of the PV module. This innovation simplifies system design and installation while enhancing reliability and energy generation, paving the way for more resilient and high-performing solar solutions.”
