Smart Heliostat Alignment System for Solar Towers

This technology improves the performance of solar tower power plants by precisely detecting and correcting misalignment in heliostat mirrors—one of the main causes of efficiency loss in these systems. It uses a combination of geometric optics and computer vision to compare real images of the heliostat field with the ideal reflection pattern. Once deviations are detected, the mirrors can be realigned quickly and accurately.

Unlike current alignment methods that require complex devices such as inclinometers, laser trackers or telephoto cameras, this system only relies on a portable standard camera and a computer, significantly reducing costs, time and operational complexity. The process is simple enough to be carried out by a single operator in the field, while achieving higher precision and reducing energy losses that can exceed 30% annually due to mirror misalignment.

The system is lightweight, scalable to large heliostat fields, and can be applied either during commissioning or periodic maintenance. Its modular nature also allows integration into existing solar tower infrastructures without major modifications.

Collaboration sought:
Industrial partners, solar energy companies and heliostat system manufacturers are sought for licensing, technical cooperation or commercial agreements to further develop, validate and bring the technology to market.
