SunLink

SunLink Corporation is launching its ‘TechTrack Distributed’ single axis tracker, the second single-axis tracker in the company's TechTrack product line, joining the internationally deployed TechTrack Centralized. Central to the system's innovation is a dynamic design feature called ‘Dynamic Stabilization’ through which the characteristics of the tracker are changed depending on real-time, sensor-observed environmental conditions. In addition, TechTrack Distributed solves the challenge associated with monitoring the thousands of electromechanical parts that make up a distributed tracker system via SunLink's ‘VERTEX Project Intelligence Platform.’

S:FLEX

S:FLEX has developed a new low-ballast pitched roof system for non-penetrative installations on composite shingle rooftops. Non-penetrative installations of PV systems on pitched roofs with composite shingle and other roofing materials places high demands on the substructure, especially on commercial buildings with low load-bearing reserves. 

S:FLEX now offers installers a new, aerodynamic installation system for the growing segments of residential and commercial buildings. Flat Direct can be used on pitched roofs with up to 30° slope and guarantees short installation times with its pre-assembled components.

A single annual subscription price provides access to hundreds of time series globally. The availability of multiple datasets gives users the ability to conduct resource risk evaluation and energy modelling - with applications throughout the project lifecycle.
 
For developers, this will help avoid dramatic shifts in project value. Large deviations between datasets highlight that a project may have greater long-term resource uncertainty and illustrate that there may be a requirement for detailed on-site irradiance measurements. Both time series and Typical Meteorological Year (TMY) data can be downloaded directly from the Solar Time Series Tool and are delivered within 24 hours.

The tool allows subscribers to compare results from up to five models for any given site.
