AIKO vs Resun Solar - solar panel manufacturer comparison

AIKO is a Chinese solar manufacturer that has become one of the leading names in all-back-contact (ABC) cell technology. The company earned BloombergNEF Tier 1 status in Q3 2024, confirming its financial bankability and ability to supply modules financed on a non-recourse basis by multiple commercial banks. Its manufacturing footprint has expanded rapidly, from roughly 20 GW of annual capacity in early 2025 to over 35 GW by mid-2026, placing it among the larger global module makers. Resun Solar, founded in 2005, operates on a much smaller scale, with production capacity estimated around 3 GW per year, and it does not currently appear on Tier 1 bankability lists. AIKO therefore holds a considerably stronger institutional and financial footprint than Resun Solar.

On the product side, AIKO's core differentiator is its proprietary ABC cell design, which moves all electrical contacts to the rear of the cell, removing front-side metal grid lines and enabling module efficiencies above 25 percent. Its lineup spans premium residential offerings, such as the Z series around 500-545 W, up to the Infinite Ultra series aimed at utility-scale projects. Resun Solar instead relies primarily on TOPCon cell technology and offers a broad standard catalog from about 420 W to 590 W, including a meaningful share of bifacial panels suited to ground-mount installations, alongside modules marketed for residential and commercial rooftops.

For a typical international buyer, particularly one financing a utility-scale or bank-backed commercial project, AIKO is the stronger default choice given its confirmed Tier 1 status and larger production base, though its ABC modules can command a price premium. Resun Solar may still be a reasonable option for smaller residential or budget-conscious installations where formal bankability matters less, but it does not match AIKO's institutional standing or manufacturing scale.
