DAH Solar vs AIKO - solar panel manufacturer comparison

Both AIKO and DAH Solar are Chinese solar module manufacturers founded in 2009, each holding Tier 1 bankable status. AIKO is publicly listed on the Shenzhen Stock Exchange (SZSE) and has established itself as a premium, technology-driven brand, consistently topping TaiyangNews global efficiency rankings for over 34 consecutive months as of 2025. DAH Solar, headquartered in Hefei in Anhui province, operates with a declared production capacity of 10 GW and a workforce exceeding 2,000 employees, positioning itself as a high-volume manufacturer capable of supplying large-scale project demand across international markets. Both companies offer average product warranties of approximately 29.5 years, reflecting confidence in long-term module durability.

AIKO's tighter portfolio of 144 panels is built around its proprietary ABC (All Back Contact) technology, which accounts for 73.6% of its lineup and delivers an industry-leading average efficiency of 23.65% and a maximum of 25.2%, with the top module rated at 805 Wp. A favorable average temperature coefficient of -0.27%/°C provides a performance edge in warmer conditions. With only 24.3% of its range being bifacial, AIKO is particularly well-suited for residential rooftop installations where roof area is constrained and maximizing power density per module is the primary objective. DAH Solar's much broader portfolio of 363 panels centers on TOPCon technology (79.6% of the range), achieving an average efficiency of 22.1% and a maximum of 23.34%, with the top model reaching 725 Wp. Critically, 87% of DAH Solar's portfolio is bifacial, making it a strong candidate for utility-scale ground-mount and commercial C&I flat-roof projects where rear-side irradiance capture can meaningfully boost annual energy yield.

Buyers choosing between the two should align their selection with project type and budget. AIKO is the stronger choice for space-constrained residential or premium commercial rooftop installations where per-panel efficiency and power output are the key drivers - a view reinforced by its 2025 SolarQuotes Installers' Choice Award. DAH Solar's extensive bifacial TOPCon lineup, high production volume, and competitive pricing make it a more practical fit for utility-scale developers and commercial integrators who require consistent large-volume supply and favor bifacial modules for ground-mount or flat-roof applications.
