Photovoltaic plant digital twin and forecasting patents: who holds the ground and where it is still open
Concentrated but not locked down. the top 5 assignees hold 56.4% of all 39 records in scope, yet 24 companies appear in the ranking at all — a long tail sits behind the leader. Filings peaked at 3 in 2019 and again in 2021, then fell to 0 by 2024 — a -100% swing over that three-year span. 2025 and 2026 counts are still incomplete because publication typically lags filing by around 18 months, so the apparent drop-off should not be read as the field slowing down.

Common questions about this landscape
Who are the leading patent holders in photovoltaic plant forecasting and digital twin technology?
The assignee ranking covers 24 companies, with the top-ranked filer holding 8 of the 39 records in scope. The top 5 assignees together hold 56.4% of all records, but the ranking flattens quickly after that — fifth place holds only 2 records and tenth place holds 1. This means the field has a defined leader but a wide, thinly-held long tail rather than a small cartel of filers.
Is patent filing in this space growing or slowing down?
Filing fell from 3 records in 2021 to 0 in 2024, a -100% swing over that span, which is the most recent complete-year comparison available. However, publication typically lags filing by around 18 months, so 2025 and 2026 counts are still incomplete and should not be read as confirmation of a slowdown. The honest read is that recent momentum has cooled from its 2019-2021 peak, but the trajectory beyond 2024 is not yet visible in the data.
What technology areas dominate photovoltaic forecasting patents?
AI-based computing (IPC class G06N) appears on 51.3% of the 39 records, ahead of meteorology-specific claims (G01W, 43.6%) and photovoltaic-specific hardware or generation claims (H02S, 30.8%). Grid and power-supply integration (H02J) and electric measurement (G01R) each appear on 23.1% of records. Because a single patent can carry several IPC classes, these figures overlap rather than sum to 100%, reflecting how often forecasting claims are bundled with AI-model and grid-integration claims.
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 Digital Twin and Forecasting 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.
