PRF Technologies (NASDAQ: PRFX) files patent for DeepSolar Predict AI

Rhea-AI Filing Summary

PRF Technologies Ltd. furnished a report highlighting a new step in its energy-technology strategy. The company has filed its first patent application for proprietary methods that model micro-climate conditions at individual solar plants to improve the accuracy of solar energy production forecasts.

The patent application protects core intellectual property behind DeepSolar Predict, PRF’s solar forecasting software platform, and follows the company’s acceptance into the NVIDIA Connect Program. The technology targets a key weakness in conventional solar forecasting, which often relies on broad regional weather data rather than localized conditions that drive actual plant output.

PRF expects that, once commercialized, the DeepSolar Predict platform could help utility-scale solar operators and energy traders optimize dispatch, reduce penalties tied to forecast errors, and enhance financial performance in volatile power markets. This initiative complements PRF’s existing pharmaceutical programs, reflecting a dual focus on extended-release pain therapies and AI-driven renewable energy optimization.

PRF Technologies Files Its First Patent Application for Solar Plant Micro-

Climate Forecast Modeling Designed to Improve Energy Production

Forecast Accuracy

Patent filing follows acceptance into the NVIDIA Connect Program

Proprietary software targets weather forecast-driven revenue optimization, reduced penalty

risk, and improved market performance for utility-scale solar assets

Tel Aviv – January 20, 2026 — PRF Technologies Ltd. (Nasdaq: PRFX) (“PRF” or the “Company”) (formerly “PainReform”) today announced that it has filed a patent application covering proprietary methods for solar plant–level micro-climate modeling designed to significantly improve the accuracy of solar energy production forecasts in competitive electric utility markets.

The patent follows acceptance into the prestigious NVIDIA Connect Program and aims to protect core intellectual property underlying DeepSolar Predict, PRF Technologies’ solar forecasting software platform. The technology is designed to address a critical limitation in conventional solar forecasting: the reliance on regional or broad-area weather models that fail to capture the highly localized conditions that directly impact power output at individual solar plants.

By modeling micro-climate behavior unique to each solar installation, the patented approach aims to enable more precise short-term and intraday production forecasts that reflect real operating conditions rather than broad regional averages. The system continuously adapts to localized environmental dynamics, allowing forecasts to evolve in real time as conditions change.

Improved forecast accuracy has direct commercial implications for solar asset owners, operators, and energy market participants. More reliable production estimates can potentially support stronger positioning in day-ahead and intraday electricity markets, reduce financial penalties from forecast errors, enhance revenue capture during favorable pricing conditions, and improve operational decision-making across plant control and energy management systems.

“In today’s competitive energy markets, forecasting accuracy directly impacts revenue, risk management, and asset performance,” said Ehud Geller, Chairman and Interim Chief Executive Officer of PRF Technologies. “This patent application represents an important step in protecting our ability to convert highly localized weather behavior into actionable production intelligence that supports smarter market participation and improved economic outcomes for solar assets.”

PRF Technologies believes that, upon commercialization, DeepSolar Predict can help utility-scale solar operators and energy traders optimize dispatch decisions, improve risk management, and enhance the overall financial performance of solar plants, particularly in markets where pricing volatility and imbalance penalties materially affect returns.

The patent filing further strengthens PRF Technologies’ growing portfolio of energy-focused intellectual property and supports the Company’s strategy to expand its presence in the rapidly growing global market for data-driven renewable energy optimization solutions.
