Company overview. Roeloffs Solutions is the registered d/b/a of Justin Arie Roeloffs, a sole proprietorship and not a corporation. Court filings describe Roeloffs as a California resident; public records and University of California Division of Agriculture and Natural Resources coverage place him in Tulare County (Tipton/Tulare, CA), where he is also identified as a dairy farmer. The business dates to roughly 2019, when Roeloffs commercialized a solar-panel cleaning system he built. Ownership is private and individual; no public ticker, parent company, employee count, or revenue figure is disclosed in any source located, and none is asserted here.
Products / services / operations. Roeloffs Solutions provides solar-panel cleaning services to solar-array owners, largely in agricultural settings. UC ANR reported in October 2019 that the company had cleaned panels generating about 30 megawatts of power in its first season, and quoted Roeloffs on dust and almond-season fouling as the core demand driver. The operation is built around a self-developed cleaning apparatus; it is a small service business, not a manufacturer or licensor.
Patent portfolio. Roeloffs is the named applicant/inventor on U.S. Patent 11,616,469 B2, "Brush-supported solar cell washing system and method," granted March 28, 2023 out of a 2020 filing (published as US 2022/0345080 A1). The patent claims a lightweight washer-head assembly whose weight rides on brush bristles rather than hydraulic supports, plus optional water-recovery and man-portable sled variants. Google Patents and Justia list additional filings under his name. The portfolio is narrow and self-generated rather than acquired.
Patent-litigation posture. The tracked data show 2 cases, both as plaintiff and none as defendant, so this is patent assertion by an individual patent owner, not defense against NPEs. Both entries concern the same single-defendant dispute against Luis Robles in the U.S. District Court for the Eastern District of California, Fresno Division (nature of suit 830, patent). One is an unassigned "at" number (1:26-at-03575), matching assigned case 1:26-cv-08030, filed in 2026. Counsel of record is Theresa H. Rava of Williams Kastner & Gibbs. Because Roeloffs is a practicing service operator asserting his own patent, the label "non-practicing entity" does not apply, though the assertion pattern is that of a small individual patent holder suing one local defendant. No information on damages, funding, or case outcome was verified.
