Design and Validation of a Passive Solar Tracking Sensor Based on Gnomon Shadow Analysis

International Journal of Photoenergy, Volume 2026, Issue 1, 2026.
Solar tracking is essential for efficiency, yet current market solutions present a trade‐off: Active systems are precise but expensive and computationally demanding, while low‐cost passive systems (e.g., LDRs) often lack accuracy. To address this gap, this work presents the design and validation of a passive solar tracking sensor based on gnomon shadow

Heliostat Cost Reduction

ASME 2007 Energy Sustainability Conference, 2007
Power towers are capable of producing solar-generated electricity and hydrogen on a large scale. Heliostats are the most important cost element of a solar power tower plant. Since they constitute ∼50% to the capital cost of the plant it is important to reduce the cost of heliostats to as low as possible to improve the economic viability of power towers.
