SENSORS PROVIDE INSTANTANEOUS FEEDBACK ON TRACKER HEALTH AS SEEN WITH SUNLINK TECHTRACK DISTRIBUTED

A multitude of monitoring devices can tell you how well your panels are performing, but what about your mounting system? SunLink is equipping solar trackers with sensors to monitor mechanical and electrical performance, as well as gather data on real-time environmental conditions to create a complete picture of system performance. Sensors report current tracker tilt, irradiance, wind, snow and flooding levels. Accelerometers measure the impact of environmental loads and forces on the mechanical structure. Electrical sensors monitor the performance of inverters, batteries and other devices. Users can make sense of the data with SunLink’s VERTEX monitoring platform, which forms an all-encompassing real-time view of what’s happening with the tracker. In the end, the sensors along with the VERTEX monitoring platform should empower solar plants to take care of themselves while providing proactive operations management to the owners.

BIFACIAL CELLS CAPTURE PREVIOUSLY REFLECTED SOLAR ENERGY AS SEEN IN SOLARWORLD BISUN MODULES

The albedo effect: When a portion of solar energy is reflected back into space. Instead of losing this reflected energy, solar panels could perform much better if they captured this leftover light. Bifacial solar cells aim to do just that. SolarWorld’s new Sunmodule Bisun product offers up to 25% more yield thanks to its bifacial, duo cells. Instead of being covered by a backsheet, the Bisun module’s backside is encased in glass, activating solar cells on both sides. Sunlight is collected on the face of the solar panels as well as reflected onto the back. Ideal for ground-mounts and flat rooftop installations, bifacial solar panels work even better when combined with reflective surfaces, such as white membrane roofs or white stones. A 330-W bifacial panel can produce energy equivalent to a conventional 410-W panel. An increased energy yield helps to reduce the pay-off period of a solar array.
