## Summary

Epever (Beijing Epsolar Technology Co., Ltd.) is a Chinese company founded in 2007 and headquartered in Beijing, with a second manufacturing site in Huizhou. It is primarily recognized as a balance-of-system (BOS) equipment brand, with MPPT and PWM charge controllers, inverter-chargers, lithium iron phosphate battery packs, and portable power stations forming the core of its catalog. While some panel-directory databases list Epever under solar modules, the company's own product communications and third-party reviews center almost entirely on controllers and energy storage, and it does not appear on any BloombergNEF or S&P Global Tier 1 solar module bankability list. Q-Cells, now operating as Hanwha Q CELLS, traces its roots to a German founding before being acquired by South Korea's Hanwha Group in 2012; it is headquartered in Seoul with European operations in Bitterfeld-Wolfen, Germany, and a flagship U.S. manufacturing campus in Dalton, Georgia. Hanwha Q CELLS has confirmed Tier 1 / BloombergNEF Top Tier Class bankability status, a combined global module production capacity of roughly 11.3 GW per year as of recent reporting, and is named a 2025 S&P Global Tier 1 Cleantech company - giving it a substantially stronger institutional footprint.

On the product side, Epever's identifiable portfolio revolves around off-grid and hybrid system hardware suited to small residential installs, RV and boat systems, solar street lights, and distributed rural electrification - contexts where a reliable charge controller or inverter matters more than the panel brand. Q-Cells, by contrast, offers a broad module lineup for residential rooftops (notably the Q.TRON and Q.PEAK DUO families), commercial rooftops, and utility-scale ground mounts. Its panels use Q.ANTUM cell technology, a proprietary variant of PERC that Q-Cells has evolved toward TOPCon in newer lines, with efficiency ratings up to roughly 22-23% and a 25-year product warranty confirmed by multiple independent reviewers.

For any buyer shopping for solar panels in 2025, Q-Cells is the relevant choice between the two names listed here - Epever does not credibly compete in the module space and is better evaluated as a charge-controller and BOS brand. If the comparison was intended to include a panel brand alongside Q-Cells, a different second manufacturer should be considered, because these two companies serve largely different segments of the solar value chain.
