AIKO vs Solar Frontier - solar panel manufacturer comparison

Solar Frontier is a Japanese company founded in 2006 as Showa Shell Solar - a subsidiary of the oil major Showa Shell Sekiyu, later absorbed into Idemitsu Kosan - and was for more than a decade the world's largest producer of CIS (copper-indium-selenide) thin-film modules, with peak annual manufacturing capacity exceeding 1 GW at its flagship Kunitomi plant in Miyazaki Prefecture. In October 2021 the company announced it would exit in-house panel production entirely, and by June 2022 it had ceased all module manufacturing, pivoting toward OEM procurement of crystalline silicon panels and a role as a project developer and systems integrator. Solar Frontier no longer appears on active BloombergNEF Tier 1 lists because it is no longer a manufacturing entity in the conventional sense. AIKO, by contrast, is a Chinese manufacturer that entered commercial production roughly a decade ago, achieved BloombergNEF Tier 1 bankability status in 2024, and has been scaling up dedicated ABC (All Back Contact) cell and module lines aggressively. In terms of current institutional footprint, AIKO is the active manufacturer with a functioning supply chain; Solar Frontier as a panel brand has largely ceased to exist in the production sense.

AIKO's product portfolio centers entirely on its proprietary n-type ABC technology, which moves all metal contacts to the rear of the cell, eliminating front-surface shading and enabling module efficiencies above 25% in its latest INFINITY generation. Product lines are segmented by scale: the Neostar series targets residential rooftops, the Comet and Nebular series address commercial and industrial installations, and the Stellar series is sized for utility-scale ground mounts. Independent laboratory sequences - including thermal cycling, damp heat, mechanical stress, and hail tests - have placed AIKO's mono-glass modules near the top of comparative rankings, and the brand won first place in the SolarQuotes Installers' Choice Awards in 2025. Solar Frontier, in its manufacturing era, was known for CIS thin-film modules suited to low-light and high-temperature environments; its legacy panels remain in operation on installed rooftops, but the brand no longer ships new product at scale.

For any buyer evaluating these two names in 2025, the practical choice is straightforward: Solar Frontier is not a viable current procurement option for new projects, as the company no longer manufactures panels. AIKO, holding Tier 1 bankability status and offering a differentiated, well-tested ABC product line across residential, commercial, and utility segments, is the only actively operating manufacturer between the two. The more relevant question for a buyer is how AIKO's premium ABC pricing compares with competing n-type TOPCon options from larger-volume Chinese peers - but on a direct Solar Frontier vs. AIKO basis, AIKO is the default by necessity.
