2.2m Tower
DETAILS
This 2.2m Tower is optimized for pre and post construction applications, including solar resource assessment (SRA) and solar resource monitoring (SMA):
- Solar sensors are mounted above the rest of the system, eliminating the possibility of reflections from the tower itself or any other sensors/accessories.
- Solar radiation measurements are positioned at the typical height of installed PV panels.
- Industry-standard solar sensors can be mounted either on our or our .
- 2.2 m height allows easy access to pyranometers for routine maintenance using a 4’ (1.2 m) step ladder.
- Several base configurations to enable ease of use in pre and post construction applications.
In addition, transportation and installation are made easier with a 66% weight reduction compared to our previous SRA tower design.
Galvanized steel tower components, made to withstand the elements, provide a strong foundation to support long-term, professional-grade solar resource assessment.
