Hoymiles vs Trina Solar - solar panel manufacturer comparison

Hoymiles is a Chinese power electronics company founded in 2012 by engineers from Zhejiang University and headquartered in Hangzhou. Its core business is microinverters and energy storage systems - it is not a solar panel manufacturer. In 2024, Hoymiles held roughly 22% of global microinverter shipments outside the United States, making it the world's second-largest microinverter supplier behind Enphase. The company achieved BloombergNEF Tier 1 status in the energy storage segment for multiple consecutive quarters through 2025 and listed on the Shanghai Stock Exchange STAR Market in late 2021. Trina Solar, founded in 1997 by Gao Jifan and headquartered in Changzhou, Jiangsu Province, is among the world's largest photovoltaic module manufacturers, with cumulative shipments surpassing 225 GW by early 2025 and annual production capacity targeting 50 GW or more. Trina Solar has maintained BloombergNEF Tier 1 PV module status for many consecutive years and has historically scored 100% in BNEF bankability surveys. On institutional footprint and overall market scale, Trina Solar is the considerably larger and more established brand.

Hoymiles focuses on module-level power electronics, offering microinverters in single, dual, and four-panel configurations alongside hybrid inverters and battery storage units. These products are aimed primarily at residential rooftop and small commercial installations where per-panel output optimization matters - such as sites with partial shading or complex roof geometries. Because Hoymiles microinverters are compatible with panels from any manufacturer, the company functions as a component supplier rather than a full-system integrator. Trina Solar, by contrast, manufactures PV modules across several families: the Vertex S+ series targets residential rooftops using N-type TOPCon cells with efficiencies around 22 to 22.3%, while the larger-format Vertex N series serves commercial and utility-scale ground-mount projects, with bifacial modules exceeding 620 W. The lineup also includes hail-resistant and dual-glass variants suited to challenging weather environments.

For a typical international buyer, Hoymiles and Trina Solar are complementary rather than competing - pairing Trina Solar panels with Hoymiles microinverters is a common and well-regarded configuration in residential and light commercial solar projects. If the purchasing decision is about PV modules alone, Trina Solar is the clear default given its production scale, long bankability record, and broad installer familiarity. If the decision is about inverter technology, Hoymiles represents a credible Tier 1 alternative to Enphase, particularly in markets outside North America where Enphase's premium pricing is harder to absorb.
