Daflsolar develops the Dual Axis Fresnel Lens (DAFL), a solar concentrator that replaces traditional mirror fields with linear Fresnel lenses and proprietary secondary optics to achieve very high concentration ratios. This enables heat engines to run at higher temperatures, reducing the size and cost of thermal conversion systems while allowing modular, off‑site manufactured units to be deployed in distributed configurations with inexpensive thermal energy storage. The technology is designed for utility‑scale CSP developers and industrial users seeking low‑cost, low‑carbon solar thermal power.

Problem
CSP (Concentrated Solar Power) plants face high capital costs because the solar field and the heat engine each account for roughly half of the total expense, limiting economic competitiveness against fossil fuels.
Solution
Daflsolar’s Dual Axis Fresnel Lens (DAFL) is a solar concentrator that replaces traditional mirror fields with linear Fresnel lenses combined with secondary optics to achieve very high solar concentration ratios. The higher concentration enables heat engines to operate at elevated temperatures, which reduces the size and cost of the thermal conversion system. By moving manufacturing off‑site and modularizing the concentrator units, DAFL lowers installation complexity and financial risk, allowing smaller, distributed deployments. The technology leverages readily available materials, making it scalable worldwide and compatible with cheap thermal energy storage to provide low‑cost, low‑carbon electricity.
Target Audience
Primary customers are utility‑scale CSP developers, renewable energy investors, and industrial users seeking cost‑effective, high‑temperature solar thermal solutions for power generation and process heat.
