## Summary

Miolentek is a Chinese manufacturer operating under Shenzhen Mioulong Technology Co., Ltd., headquartered in Shenzhen and exporting since approximately 2015. The company focuses on small-format and specialty solar panels - PET, ETFE, epoxy, glass, and semi-flexible variants - primarily targeting portable and off-grid applications rather than rooftop or utility-scale installations. It does not appear on any BloombergNEF Tier 1 or comparable bankability list, and its annual output is measured in small-wattage panel pieces rather than gigawatts of module capacity. Q-Cells, now operating as Hanwha Q CELLS under South Korea's Hanwha Group following its 2012 acquisition of the original German Q-Cells AG (founded 1999), is a confirmed BloombergNEF Tier 1 manufacturer and was named an S&P Global 2025 Tier 1 Cleantech company. Its total U.S.-based module production capacity alone has reached 8.4 GW annually, with global cell and module capacity well into double-digit gigawatts. Q-Cells carries a substantially larger and more established institutional footprint by any measure.

The two brands serve entirely different market segments, which makes a direct product-to-product comparison difficult. Miolentek's catalog runs from milliwatt epoxy cells used in small electronics up to semi-flexible panels of around 100-160 W, making it relevant for camping gear, marine applications, portable chargers, and lightweight off-grid setups. Q-Cells addresses mainstream residential rooftops and commercial installations with its Q.ANTUM PERC-based and Q.ANTUM NEO TOPCon-based panel families, achieving efficiencies up to roughly 22-23% in its Q.TRON residential series, backed by 25-year product warranties and strong degradation guarantees.

For any buyer considering conventional rooftop or grid-tied solar in 2025, Q-Cells is the clear default choice - it offers proven technology, Tier 1 bankability, robust warranty support, and competitive pricing at the mid-range. Miolentek is not a substitute in that segment; it occupies a niche portable and flexible panel space where institutional bankability is less relevant and where it competes with other specialty Chinese OEM suppliers rather than with mainstream panel brands.
