Solar Collector Calibration for Accurate Sun Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar collector systems face challenges in accurately aligning with the sun due to imperfections in construction and installation, leading to inefficiencies and high costs associated with site preparation and precise foundation construction.
Innovation Solution
A calibration tool that collects data on the solar collector's movement, compares it to expected sun movement data, and generates offset information to adjust the collector's position using servomechanisms for optimal alignment, reducing the need for precise site preparation and component accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise foundation construction and site preparation are implemented to ensure accurate solar collector alignment, then alignment precision is improved, but installation cost increases
Solution Approach 1:
The calibration tool performs preliminary alignment measurements and generates correction data before the solar collector begins operational tracking. By conducting the alignment calibration in advance during installation, the system eliminates the need for expensive precise foundation construction, as the calibration data compensates for installation imperfections
Solution Approach 2:
The calibration tool incorporates sensors that measure the actual position of the solar collector during tracking movement and compare it against expected positions. This feedback mechanism generates correction data that compensates for alignment deviations, allowing the system to achieve precise sun tracking without requiring expensive precise mechanical installation
2Adaptability or versatility
If multiple supports and mechanical linkages are used to control collector movement, then tracking capability is improved, but device complexity increases
Solution Approach 1:
The calibration tool replaces complex mechanical alignment systems with a software-based calibration approach. Instead of using multiple mechanical supports and linkages to physically ensure precise alignment, the system uses sensors to measure actual positions and software to generate correction data, substituting mechanical complexity with computational simplicity
3Ease of manufacture
If standard solar collector designs are used without calibration, then manufacturing simplicity is maintained, but alignment accuracy deteriorates
Solution Approach 1:
The calibration tool changes the operational parameters of the solar collector by generating correction data that adjusts the tracking angles. Instead of modifying the physical collector design to ensure precise alignment, the system modifies the tracking parameters through software calibration, allowing standard collectors to achieve high alignment accuracy

AI summary
A solar concentrator calibration tool that compensates for inconsistencies in the fabrication, assembly and installation of a solar collector system, permitting the solar collector to perform optimally. The calibration tool provides feedback information to a supervisory control processor, allowing the processor to compare the expected position of the sun to the “actual” position found by the calibration tool. The processor then generates a calibration signal, thereafter used by the collector's movement control mechanism, to compensate the tracking of the solar collector to accurately follow the movement of the sun, unconstrained by the effects of the construction inconsistencies.
