Soltec has developed a brand new bifacial monitoring algorithm to find out the optimum angle for photo voltaic trackers to maximise the manufacturing of particular bifacial modules in photo voltaic crops.

The algorithm estimates the facility technology for various angles, bearing in mind the back and front irradiance and the efficiency of the module. It makes use of Soltec’s personal developed astronomical algorithm based mostly on photo voltaic positioning knowledge from NREL-SPA.

The algorithm considers plant parameters, akin to albedo and soil albedo, which may be dynamically configured for higher effectivity. Analytical and experimental checks have been carried out at completely different latitudes, exhibiting a rise in energy technology from 0.10% to 0.12%, relying on the situation and albedo situations.

The effectiveness of the algorithm varies from month to month, with larger features noticed at low solar angles and winter months. Whereas the potential whole revenue of the algorithm is 0.29% (0.41% throughout activation), the precise revenue obtained is 0.18% attributable to inaccuracies within the climate forecast.

Soltec estimates an financial revenue of €6,192 ($6,698) per yr for a 50 MW plant at Mediterranean latitude underneath 30% albedo situations. The algorithm helps different Soltec monitoring algorithms, akin to TeamTrack and Diffuse Booster, which reply to shading and enhance manufacturing throughout diffuse radiation, respectively.
