Module Racks Cranks Out More Solar Power

Compared to a fixed tilt system, BIG SUN Energy's patented iPV Tracker shows a 30% increase in power generation. When iPV Tracker is combined with a bi-facial module there is a further 10% increase. BIG SUN Energy has further researched various underlying surfaces -- discovering the rates of reflection with natural ground cover, cement or mirror-like reflective surfaces.

 

Reflection rates of grass, sand or mud will increase the power generation between 5-10%, while white cement will provide a 15% increase. When mirror-like reflective surfaces such as water or snow are used, the gains reach 20-30%. By installing an iPV Tracker over a water surface using bi-facial modules, the increase in yields achieved can reach 60% over fixed tilt systems utilizing mono-facial modules.

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

The effectiveness of PV power generation has three essential factors, inclination angle, height and ground reflection.

  • The inclination angle is the optimal angle that power generation systems can track and absorb sunlight.
  • Tracker height describes the necessary room to collect reflected and diffused sunlight on the rear side of a module when paired with a bi-facial module.
  • Ground reflection can boost the rear side power generation in bi-facial modules, with different advantages for different types of ground cover.
