Photovoltaic Plant Performance Monitoring Patents: Leaders & Trends 2026
Photovoltaic Plant Performance Monitoring Patents: Who Leads and Where Filings Are Heading
Filings peaked in 2017 at 21 records and the 2021→2024 span shows a -53% pull-back — read the most recent two years as still filling in, not as a verdict on the field. Filings peaked in 2017 at 21 records. The 2021 to 2024 span, the last window with reliable completeness, moved from 15 to 7 records — a -53% change. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and should not be read as a continued decline.

Common questions on this landscape
Who holds the most patents in photovoltaic plant performance monitoring?
In this 192-record corpus, one assignee leads with 30 records, well ahead of the rest of the ranked list. The top 5 assignees combined account for 38.0% of all 192 records in scope, and the top 10 combined reach 53.6%. Beyond that, the ranked list of 79 assignees thins out quickly into single- and few-filing entrants, so the field has one clear leader rather than a tight cluster of comparably sized competitors.
Is patent filing activity in this field growing or shrinking?
Filings peaked in 2017 at 21 records and, across the last window with reliable completeness, fell from 15 in 2021 to 7 in 2024 — a -53% change. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in any dataset are still incomplete and should not be read as continuing that decline. The honest read is that the 2021-2024 window shows cooling, and later years are simply unresolved yet.
What technology classes cover photovoltaic plant performance monitoring patents?
H02S, the photovoltaic and solar power generation class, covers 21.9% of the 192 records in scope, but it is not the majority of the field. G01N (material analysis and testing) at 14.6%, H02J (power supply and grid systems) at 9.9%, and H01M (batteries and cells) at 8.9% all carry meaningful shares. Because records can carry multiple IPC classes, these percentages are each measured against the same 192-record total independently rather than summing to 100%.
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 Photovoltaic Plant Performance Monitoring 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.
