Written summary
Easun Power is a Chinese electronics and energy company founded around 2008 and headquartered in China, with its primary identity built around solar inverters, hybrid charge controllers, and LiFePO4 battery storage rather than solar modules. The company claims cumulative installations exceeding 10 GW across more than 100 countries, though that figure reflects inverter deployments. Easun Power does sell solar panels under its brand, but they represent a secondary product line, and the company does not appear on BloombergNEF's Tier 1 Solar Module Maker list. AIKO - formally Shanghai Aiko Solar Energy Co., Ltd. - was founded in 1996 and is headquartered in Shanghai, with manufacturing spread across production bases in Guangdong, Zhejiang, and Shandong. AIKO achieved BloombergNEF Tier 1 bankability status in Q3 2024 and reported approximately 20 GW of annual module production capacity as of early 2025. On institutional standing as a solar panel manufacturer, AIKO holds a clear advantage.
The product profiles of the two companies point in quite different directions. Easun Power's solar panels are sold primarily as accessories to its inverter and storage ecosystem, making them most relevant for budget-conscious off-grid or hybrid residential setups where buyers are already using Easun inverters. Customer reliability feedback from forums and review platforms has been mixed, with some reports of quality control issues. AIKO, by contrast, has built its entire business around one ambitious technology: N-type All Back Contact cells, which relocate all electrical contacts to the rear of the cell. This approach has delivered mass-production module efficiencies above 24%, and AIKO took first place in the 2025 SolarQuotes Installers' Choice Awards. The Neostar product family targets premium residential and compact commercial rooftops where space efficiency and long-term yield justify a higher upfront price. AIKO also offers a 30-year performance warranty with an annual degradation rate of 0.35% after year one.
For a buyer evaluating solar panels specifically, AIKO is the stronger default choice in 2025: it is a dedicated module manufacturer with verified Tier 1 bankability, proven high-efficiency technology, and growing installer endorsement. Easun Power is a reasonable option only if a buyer is already invested in the Easun inverter ecosystem and prioritizes a lower entry price over module performance or long-term institutional support.
