Written summary
Sunpro Power is a Chinese solar module manufacturer headquartered in Yuhuan City, Zhejiang Province, operating under Zhejiang Sunpro Power Technology Co., Ltd. The company has held a position on the BloombergNEF Tier 1 module manufacturer list for multiple consecutive years, confirming its bankability with international project financiers. Its reported production capacity is approximately 3 GW per year, supported by a manufacturing layout spanning China, Poland, and Indonesia. AIKO - formally Guangdong Aiko Solar Energy Technology Co., Ltd. - was founded in 2009 and achieved BloombergNEF Tier 1 status in Q3 2024. By early 2025 its production capacity was reported at around 20 GW, placing it in a substantially larger league. Between the two, AIKO carries the stronger institutional footprint and greater scale.
Sunpro Power covers a wide range of cell technologies including TOPCon, HJT, PERC, and BC variants, targeting utility, residential, commercial, and agricultural segments. Its positioning leans toward the budget-to-mid market tier, offering competitive pricing and modules certified by TUV Suddeutsche, UL, and CE. AIKO has built its identity almost entirely around its proprietary ABC (All Back Contact) N-type cell technology, which moves all electrical contacts to the rear of the cell to minimize shading losses and push efficiency higher. The Neostar series is AIKO's flagship residential product, reaching module-level efficiency around 24% in mass production - among the highest figures commercially available globally. AIKO took first place in the 2025 SolarQuotes Installers' Choice Awards, reinforcing its premium reputation.
For a typical buyer in 2025, the choice hinges on budget and space constraints. AIKO is the stronger pick where roof area is limited and maximum yield per square meter is the priority, with its ABC technology offering a confirmed edge in low-light and partial-shade conditions. Sunpro Power is a credible alternative for cost-sensitive residential or commercial projects where standard efficiency is sufficient and technology flexibility is valued. The two brands are not interchangeable - AIKO targets the premium end while Sunpro Power competes on value.
