Within roughly three years of operation the firm reported over 50 MW of installed power across residential, commercial, and ground-mount projects in Italy, drawing on the heritage of a larger energy group with more than four decades of operating history. AIKO, by contrast, is a Chinese panel manufacturer established in Guangzhou and focused exclusively on its proprietary N-type ABC (All-Back-Contact) cell technology. AIKO holds BloombergNEF Tier 1 bankable-supplier status as of Q3 2024 and has expanded its production capacity to approximately 20 GW per year, making it one of the more rapidly scaling specialists in the global module market. On institutional footprint and manufacturing depth, AIKO is in an entirely different category. Because Esse Solar operates as an installer and distributor rather than a panel producer, the two brands serve fundamentally different roles in the supply chain. Esse Solar's offering covers turnkey photovoltaic and thermal-hydraulic systems for the Italian market, integrating third-party modules with heat-pump solutions for residential and industrial customers. AIKO's own product lineup, centred on its Neostar and Comet series, targets premium residential rooftops and commercial applications where maximum power density matters; its ABC modules have repeatedly topped the TaiyangNews global efficiency rankings, with mass-produced modules reaching confirmed efficiencies above 24% as of late 2025. AIKO has also begun winning utility-scale procurement bids in China and is expanding into European and Southeast Asian markets. For a buyer selecting a panel brand, Esse Solar is not a comparable option - it is a potential installer or distributor, not a module origin. Anyone evaluating AIKO modules for a European project would typically engage a local EPC partner like Esse Solar to handle procurement logistics and installation. AIKO is the stronger default choice for buyers who specifically want high-efficiency N-type modules backed by bankable manufacturer warranties, while Esse Solar is relevant to Italian buyers seeking a competent local integration partner regardless of which panel brand they ultimately specify. \---LINKS--- \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| AIKO Solar panels independent review - SolarQuotes \| review \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11 GW capacity upgrade - PV Tech \| article \- https://www.pv-magazine.com/2025/02/07/aiko-launches-new-rooftop-solar-panels-with-24-3-efficiency/ \| Aiko launches rooftop panels with 24.3% efficiency - pv magazine \| article \- https://www.enfsolar.com/esse-solar \| Esse Solar S.r.l. company profile - ENF Solar directory \| article \- https://www.fimer.com/fimer-and-esse-solar-new-860-kwp-photovoltaic-plant-modena-italy \| FIMER and Esse Solar - 860 kWp plant in Modena \| article Sources: \- \[AIKO Solar panels independent review - SolarQuotes\](https://www.solarquotes.com.au/panels/aiko-solar-review.html) \- \[Aiko steps up ABC transition with 11 GW capacity upgrade - PV Tech\](https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/) \- \[Aiko launches rooftop panels with 24.3% efficiency - pv magazine\](https://www.pv-magazine.com/2025/02/07/aiko-launches-new-rooftop-solar-panels-with-24-3-efficiency/) \- \[Esse Solar S.r.l. company profile - ENF Solar\](https://www.enfsolar.com/esse-solar) \- \[FIMER and Esse Solar - 860 kWp plant in Modena\](https://www.fimer.com/fimer-and-esse-solar-new-860-kwp-photovoltaic-plant-modena-italy) Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
