The company operates primarily in the German and broader European market, advising on, planning, and installing PV systems for residential, commercial, and solar-park customers, and sources the panels it sells from third-party makers. Because it does not carry its own branded module production line, it does not appear on BloombergNEF Tier 1 manufacturer rankings, which require a track record of supplying own-brand, self-produced modules to utility-scale projects financed by major lenders. Solar Frontier, by contrast, was for many years a genuine manufacturer - a Japanese company and subsidiary of energy conglomerate Idemitsu Kosan, headquartered in Tokyo, and at its peak the world's largest producer of copper indium selenide (CIS) thin-film panels, operating a 900 MW Kunitomi plant in Miyazaki Prefecture. However, Idemitsu announced a business restructuring in late 2021, and Solar Frontier ceased all CIS thin-film module production by mid-2022. The company relaunched on an OEM basis with a crystalline silicon offering sourced from external suppliers. On institutional footprint, Solar Frontier's historical scale and parent-company backing gave it the stronger name recognition, though that legacy counts for little if sourcing is now outsourced. As of 2025, AEET Energy Group's product offering reflects whichever third-party modules it selects for a given project - technology mix and cell type therefore vary and cannot be fixed as a brand-level characteristic. Solar Frontier's current OEM monocrystalline line, introduced at 250 W for the residential segment, positions the brand toward smaller rooftop applications in Japan, though its market activity appears minimal and no new product family has attracted significant independent review coverage in recent years. AEET, given its installer-distributor role, is best understood as a one-stop service channel in Europe rather than a panel brand that a buyer would specify by name on a product sheet. For a typical buyer in 2025 choosing between these two names on a module specification, neither represents a straightforward off-the-shelf module brand with a clear, current manufacturing identity. AEET Energy Group suits European project buyers who want a local integrator relationship rather than a standalone panel purchase. Solar Frontier, despite its pioneering CIS heritage, has effectively stepped back from active module supply at scale. Buyers seeking a bankable, high-volume crystalline silicon panel would do better to evaluate manufacturers with current confirmed Tier 1 status - these two brands occupy very different, and currently narrow, niches. \---LINKS--- \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH company profile - ENF Solar \| article \- https://www.pv-magazine.com/2021/11/01/solar-frontier-abandons-thin-film-launches-250-w-monocrystalline-panel/ \| Solar Frontier abandons thin-film, launches 250 W monocrystalline panel \| article \- https://reneweconomy.com.au/another-blow-to-thin-film-as-solar-frontier-quits-manufacturing-and-switches-sides/ \| Solar Frontier quits manufacturing and switches sides - RenewEconomy \| article \- https://www.solarreviews.com/manufacturers/solar-frontier \| Solar Frontier panels review - SolarReviews \| review \- https://energypal.com/best-solar-panels-for-homes/aeet-energy-group \| AEET Energy Group - EnergyPal Buyer's Guide \| review Sources: \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) \- \[Solar Frontier abandons thin-film, launches 250 W monocrystalline panel - PV Magazine\](https://www.pv-magazine.com/2021/11/01/solar-frontier-abandons-thin-film-launches-250-w-monocrystalline-panel/) \- \[Solar Frontier quits manufacturing and switches sides - RenewEconomy\](https://reneweconomy.com.au/another-blow-to-thin-film-as-solar-frontier-quits-manufacturing-and-switches-sides/) \- \[Solar Frontier panels review - SolarReviews\](https://www.solarreviews.com/manufacturers/solar-frontier) \- \[AEET Energy Group - EnergyPal Buyer's Guide\](https://energypal.com/best-solar-panels-for-homes/aeet-energy-group) Written by claude-sonnet from the figures above. ## Other comparisons - [AEET vs A.B.
