Bifacial and Tracker Compatible Module Patents: Who Holds the Claims
Three assignees account for all 18 records in scope, with no long tail of smaller filers behind them — this is a concentrated field, not a fragmented one. Activity built to a peak of 7 filings in 2020, then dropped sharply. By 2024 — the most recent year that can be treated as complete once publication lag is accounted for — annual filings had fallen to 0, a -100% change from the 2021 level of 7. Readings from 2025 onward are still filling in and should not be read as a continued decline.

Common questions on this landscape
Who holds the most patents on bifacial and tracker compatible modules?
This dataset's assignee ranking returns three companies covering all 18 records in scope, and one of them holds 15 of those 18 — a strong concentration rather than a fragmented field. That leader's portfolio is the first thing to check for freedom-to-operate before filing anything that combines bifacial module claims with single-axis tracker claims. The other two ranked assignees hold the remainder, with no filings from any of the three in the most recent year.
Is filing activity in this space growing or shrinking?
Filing activity peaked at 7 records in 2020 and had dropped to 0 by 2024, a -100% change over that three-year span, and 2024 is the most recent year the data treats as complete. Years from 2025 onward are still filling in because publication lags filing by roughly 18 months, so those low counts should not yet be read as continued decline. Taken together, the pattern looks like an early land-grab followed by a pause rather than a technology in active growth.
What does EP4002685B1 actually cover?
EP4002685B1, granted to SOLTEC INNOVATIONS, S.L. in 2023, claims a single-axis solar tracker and its operating method for bifacial photovoltaic modules. It sits in the same subject area as the two most-cited records in this dataset, both of which pair tracker mechanics with bifacial-module operation rather than claiming either in isolation. Anyone building a tracker control method for bifacial arrays should read its independent claims closely before assuming a workaround is unnecessary.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Bifacial and Tracker Compatible Modules covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
