The company reports a module production capacity of around 3.2 GW per year and distributes products across more than 50 countries, positioning itself broadly across commercial and residential markets. No confirmed BloombergNEF Tier 1 bankability listing for ECODELTA appeared in current industry sources. AIKO Solar, also Chinese, achieved BloombergNEF Tier 1 status in Q3 2024 and had a reported production capacity of around 20 GW as of early 2025, placing it firmly among the second tier of global volume leaders behind the Big Four. On institutional footprint and bankability recognition, AIKO currently holds the stronger position. ECODELTA's catalog spans monocrystalline half-cut and shingled modules, with the shingled line - which uses electrically conductive adhesive rather than solder ribbon to reduce shading loss - serving as its main differentiator for residential and light commercial rooftop installations. AIKO's product identity is built almost entirely around its proprietary N-type ABC (All Back Contact) cell platform, which web searches confirm has reached mass-production module efficiencies exceeding 24%. AIKO organizes its range into the Neostar series targeting premium residential rooftops, the Comet series for commercial and industrial applications, and the Stellar series for utility-scale ground mounts. AIKO took first place in the 2025 SolarQuotes Installers' Choice Awards in Australia, reflecting strong installer confidence. For most buyers in 2025, AIKO is the stronger default choice where budget allows: confirmed Tier 1 bankability, documented efficiency leadership, a 30-year performance warranty with a low annual degradation ceiling of 0.35%, and growing installer adoption give it a clear edge for premium residential and financed commercial projects. ECODELTA remains a credible mid-tier option for cost-sensitive buyers or markets where AIKO distribution is thin, but its institutional standing is less independently verified. \---LINKS--- \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review and installer ratings - SolarQuotes \| review \- https://www.pv-magazine.com/2025/02/07/aiko-launches-new-rooftop-solar-panels-with-24-3-efficiency/ \| Aiko launches rooftop solar panels with 24.3% efficiency - PV Magazine \| article \- 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://taiyangnews.info/technology/aiko-solar-abc-module-power-efficiency \| AIKO ABC module technology overview - Taiyang News \| article \- https://energypal.com/best-solar-panels-for-homes/eco-delta-power \| Eco Delta Power buyer's guide entry - EnergyPal \| review Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
