Esse Solar is an Italian company that provides solar solutions to solar professionals, businesses, and individuals who want to improve their energy efficiency. The company was founded in 1991 and is based in Gallarate. Esse Solar has raised $6.54M in funding from VAM Investments. ## Catalog & Power | Measure | ASM | Esse Solar | Margin | | --- | --- | --- | --- | | Panel Models | 1 | 0 | +1 | | Max Power | 170 W | 0 W | +170 W | | Avg Power | 170 W | 0 W | +170 W | ## Efficiency | Measure | ASM | Esse Solar | Margin | | --- | --- | --- | --- | | Max Efficiency | 16.00% | - | | | Avg Efficiency | 16.00% | - | | ## Reliability & Warranty | Measure | ASM | Esse Solar | Margin | | --- | --- | --- | --- | | Avg Temp Coefficient | -0.438%/°C | - | | | Bifacial Share | 0 (0%) | 0 (0%) | | | Avg Warranty | - | - | | ## Efficiency distribution | Efficiency band | ASM | Esse Solar | | --- | --- | --- | | \<20% | 1 (100.0%) | 0 | ## Power distribution | Power band | ASM | Esse Solar | | --- | --- | --- | | \<400W | 1 (100.0%) | 0 | ## Cell technology | Technology | ASM | Esse Solar | | --- | --- | --- | | Unknown | 1 (100.0%) | 0 | ## Top panels, ASM | # | Model | Power | Efficiency | Temp. coefficient | Technology | | --- | --- | --- | --- | --- | --- | | 1 | [ASM170M](https://comparepv.com/panel/australian-solar-manufacturing-asm170m) | 170 | 16.0 | -0.438 | Monocrystalline | ## Summary ASM, headquartered in Australia and founded in 2009, operates as a micro-scale solar manufacturer or integrator with a reported headcount of just one to ten employees. The company does not hold Tier 1 bankability status as assessed by BloombergNEF, meaning it has not demonstrated the project volume and debt-financing track record that institutional lenders typically require. Esse Solar, based in Gallarate, Italy, was founded in 1991 and employs between eleven and fifty people, giving it a modestly longer operating history and a slightly larger organisational footprint. Neither company appears on major Tier 1 module lists, and open-source industry databases indicate both function closer to the systems-integrator or small-batch niche than to volume panel manufacturing. On institutional footprint, Esse Solar holds a marginal edge by virtue of its longer operating history and confirmed involvement in projects such as a collaborative 860 kWp installation in Modena alongside inverter supplier FIMER. Portfolio data for both manufacturers is not publicly available in aggregated form, so no concrete watt-peak, efficiency, or bifacial figures can be cited here without risking fabrication. What the available record does suggest is that ASM targets the Australian residential and small commercial market, likely drawing on local assembly or sourcing to offer proximity-based service advantages. Esse Solar, by contrast, positions itself as a turnkey PV solutions provider for the Italian and broader southern European market, supplying both components and project management rather than competing primarily on panel specifications. Neither lineup shows documented evidence of high-power bifacial modules or top-tier cell technologies that would place them alongside mainstream volume manufacturers. For a typical buyer in 2025, neither company represents a default recommendation over established Tier 1 producers. If geographic proximity and local after-sales support in Australia are paramount, ASM may warrant consideration on that basis alone. Italian or European buyers with a preference for a locally managed turnkey project could explore Esse Solar, which has a longer track record in that context. Outside these narrow regional use cases, both manufacturers occupy a niche that larger, bankable producers comfortably serve with better-documented warranties, more transparent specifications, and stronger financing support. \---LINKS--- \- https://www.enfsolar.com/asm \| ASM - Australian Solar Manufacturing company profile on ENF Solar \| review \- https://www.enfsolar.com/esse-solar \| Esse Solar S.r.l. company profile on ENF Solar \| review \- https://www.fimer.com/fimer-and-esse-solar-new-860-kwp-photovoltaic-plant-modena-italy \| FIMER and Esse Solar - 860 kWp photovoltaic plant in Modena, Italy \| article \- https://assets.bnef.com/public/tiering/solarmodules.pdf \| BloombergNEF Tier 1 Solar Module Methodology - March 2026 \| article Sources: \- \[ASM on ENF Solar\](https://www.enfsolar.com/asm) \- \[Esse Solar on ENF Solar\](https://www.enfsolar.com/esse-solar) \- \[FIMER and Esse Solar - 860 kWp project in Modena\](https://www.fimer.com/fimer-and-esse-solar-new-860-kwp-photovoltaic-plant-modena-italy) \- \[BloombergNEF Tier 1 Solar Module Methodology\](https://assets.bnef.com/public/tiering/solarmodules.pdf) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
