Written summary
Solplanet is a Chinese brand operating under AISWEI Technology, a company that traces its roots to SMA's former Chinese subsidiary and has been operating independently since around 2009, with headquarters in China. AISWEI earned a DNV bankability review that confirmed it meets international standards, and its Solplanet inverter line ranked ninth globally in Wood Mackenzie's H1 2025 inverter rankings - a meaningful institutional signal. AIKO Solar is also a Chinese manufacturer, founded in 2009 and headquartered in Yiwu and Shanghai, and has achieved full BloombergNEF Tier 1 status for its solar modules, placing it in the top 2% of global panel makers by bankability. In terms of institutional recognition specifically for solar modules, AIKO holds the stronger position.
The two brands are, however, not directly comparable as solar-panel manufacturers. Solplanet is primarily a solar inverter and balance-of-system brand - its product portfolio centers on string inverters, hybrid inverters, EV chargers, and monitoring solutions, with no confirmed standalone solar module lineup as of mid-2025. AIKO, by contrast, is a dedicated module manufacturer whose signature technology is ABC (All Back Contact), an N-type cell architecture that moves all electrical contacts to the rear of the cell to maximize light capture. AIKO claimed a world record of 24.4% mass-production module efficiency in 2025, consistently tops the Taiyangnews global efficiency rankings, and backs its panels with a 30-year performance warranty degrading to no less than 88.85% of rated output - terms well above the industry norm. AIKO panels target premium residential and commercial rooftop segments where space efficiency and long-term yield matter most.
For a buyer comparing these two brands specifically as solar-panel suppliers, the choice is essentially settled by product category: AIKO is a genuine panel manufacturer with a strong efficiency record and Tier 1 bankability, while Solplanet's strength lies in inverter hardware. A buyer assembling a complete solar system might reasonably pair AIKO modules with a Solplanet or another inverter, but they are not substitutes for one another in the panel market.
