## Summary

Hanersun is a Chinese solar module manufacturer headquartered in Nanjing, founded in 2015 and operating under its current name since 2022 following a rebrand from CSUNPOWER. The brand is listed as a Tier 1 manufacturer by BloombergNEF, earned a Kiwa PVEL Top Performer award, and appears on PVBL's Top 100 Global PV Companies list. By the end of 2025 Hanersun had cumulatively shipped over 16 GW of modules, with an estimated annual production capacity of around 5 GW, and it maintains branches across the US, Europe, Japan and Australia. MY Solar, also marketed as Mysolar or iMysolar, is a brand of the US company Mamibot, originally founded in 2013 as a robotic home-cleaning manufacturer, with a US headquarters in Wilmington, Delaware and a manufacturing facility in Shanghai. Unlike Hanersun, MY Solar is still working toward Tier 1 recognition and has no confirmed BloombergNEF listing, giving Hanersun a clearly stronger institutional footprint.

Hanersun's lineup centers on N-type TOPCon and HJT cell technology, including its HITOUCH series with back-contact and TOPCon modules ranging roughly from 440 W to 590 W, aimed at residential, commercial and utility-scale projects, alongside HISMART and HNESS energy storage products. MY Solar offers a broader and more varied catalog spanning conventional mono-PERC panels, shingled PERC modules in both mono-facial and bifacial formats, and higher-end HJT half-cell modules, with TOPCon models from 450 W to 710 W and HJT units up to 730 W, targeted primarily at the US residential and light commercial market.

For a typical buyer, particularly outside the US, Hanersun is the safer default given its confirmed Tier 1 status, longer supply track record and documented production scale. MY Solar may appeal to US-based buyers drawn to its wide technology range, but its still-developing bankability track record warrants extra diligence before large-scale procurement.
