Aptos Solar Technology, LLC

Aptos Solar Technology, LLC — commonly "Aptos Solar" — is a privately held U.S. solar equipment manufacturer founded in 2019 by industry veterans Alex Kim and Thanh "Frank" Pham, both formerly of Mission Solar. Public listings give conflicting headquarters: Santa Clara, California (PitchBook, Crunchbase, CB Insights) and San Antonio, Texas (SRS Distribution, company contact listings), with a sales office in San Antonio and manufacturing in Vietnam. It is not publicly traded. Headcount estimates are low and inconsistent across directories (roughly 10–50 employees; PitchBook lists 14). No verified revenue figures are available from public sources.

Products / operations. Aptos is an operating manufacturer and supplier of photovoltaic modules and microinverters for residential, commercial, and utility use. Its solar panel lines include the DNA-120 and DNA-144 series of half-cut-cell monocrystalline modules (P-type PERC and N-type TOPCon variants, monofacial and bifacial double-glass builds, roughly 330–590 W) marketed under its patented "Dual Nano Absorber" (DNA) cell technology. It also sells the MAC-400 and MAC-800 microinverters, distributed through channels such as SRS Distribution and listed on California's Energy Commission equipment lists. Aptos panels were used in SunPower's U-Series line before SunPower's bankruptcy. Products carry a 25-year product / 30-year performance warranty.

Patent-litigation posture. Aptos is an operating company and a pure defendant: 0 plaintiff cases, 1 defendant case in the tracked data. That pattern — no assertions of its own — is consistent with a product manufacturer defending infringement claims rather than a non-practicing entity or active two-way litigant.

Notable case. CyboEnergy, Inc. v. Aptos Solar Technology, LLC (W.D. Tex., Waco Division, filed 2022-03-16, No. 6:22-cv-00281) accused Aptos of infringing U.S. Patent Nos. 8,786,133 ("Smart and Scalable Power Inverters") and 9,331,489 ("Solar Power Mini-Inverters"). Plaintiff CyboEnergy, described by Unified Patents as an NPE, has asserted the same family against Sensata, Altenergy Power Systems, Hoymiles, Duracell, and Yotta Energy; the Waco venue reflects the plaintiff-friendly W.D. Tex. forum choice.
