The company occupies a niche position as one of the few operations that puts panels together on Australian soil, though it sources photovoltaic cells rather than fabricating them domestically. ASM does not appear on any BloombergNEF or equivalent Tier 1 module bankability list, and its production scale remains modest relative to global peers. Growatt (Shenzhen Growatt New Energy Co., Ltd.) was founded in 2010 in Shenzhen, China, with its principal manufacturing campus in Huizhou, and has expanded to more than 180 countries; it is ranked the world's leading residential inverter supplier by shipment volume. Growatt is, however, primarily a power-electronics company - its core catalog covers grid-tied inverters, hybrid inverters, energy-storage systems, and EV chargers - and search results do not indicate it manufactures solar panels as a primary product line. By institutional scale and global recognition, Growatt is far larger, though that stature is built on inverters rather than modules. ASM's panel catalog has historically centered on residential monocrystalline modules in the 170W to 200W range, marketed under an Australian-made identity and targeting homeowners who prioritize local provenance. Those specifications are modest against today's mainstream offerings, where TOPCon and higher-efficiency modules from global Tier 1 suppliers routinely exceed 400W per panel. Growatt's product portfolio, by contrast, does not appear to include solar panels; buyers will find inverters, battery-ready hybrid units, and portable power stations under the Growatt brand, designed to be paired with panels from other manufacturers. For a typical buyer in 2025, comparing these two as solar-panel manufacturers is problematic because they serve fundamentally different roles. ASM addresses a small, provenance-driven residential niche in Australia with locally assembled modules. Growatt is a capable, cost-competitive inverter and storage brand, but it is not a panel source. A buyer would be better served evaluating ASM's modules against other panel brands on efficiency and bankability, while treating Growatt as a mid-market inverter option to be assessed separately. \---LINKS--- \- https://www.enfsolar.com/asm \| Australian Solar Manufacturing Pty Ltd - ENF Solar database profile \| article \- https://solartechonline.com/blog/growatt-solar-inverter-review-guide/ \| Growatt Solar Inverter Review 2025: Complete Performance Guide \| review \- https://www.solarchoice.net.au/products/inverters/Growatt-Review/ \| Growatt Solar Inverters: Independent Review - Solar Choice \| review \- https://www.energymatters.com.au/renewable-news/growatt-inverter-review-in-2025-what-to-know/ \| Growatt Inverter Review 2025 - Energy Matters Australia \| review Sources: \- \[Australian Solar Manufacturing - ENF Solar\](https://www.enfsolar.com/asm) \- \[Growatt Solar Inverter Review 2025\](https://solartechonline.com/blog/growatt-solar-inverter-review-guide/) \- \[Growatt Solar Inverters: Independent Review - Solar Choice\](https://www.solarchoice.net.au/products/inverters/Growatt-Review/) \- \[Growatt Inverter Review 2025 - Energy Matters\](https://www.energymatters.com.au/renewable-news/growatt-inverter-review-in-2025-what-to-know/) \- \[Growatt About - Our Story\](https://en.growatt.com/about/our-story) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
