In this presentation, Array CFO Bob Bellemare discusses the growth of the solar tracker industry, the technological innovation making trackers invaluable to PV installations and the benefits offered to solar customers through the addition of long-lasting solar tracker assets. The presentation also explores: • The importance of tracker design and how it supports both cost savings and long-term yield optimization through reliability • The advantages of time-tested solar trackers and how reliable products maximize site economics • Real-world examples from Array Technologies’ 375+ installations around the world

4. Solar is maturing rapidly
Reliability is Power4
Rapidly dropping PPA prices create
• Hyper competition
• Need to balance cost – quality
To maximize production and
minimize cost, focus on
• High reliability and low cost of
ownership
• Removing logistical challenges

5. Tracking improves solar asset value
Reliability is Power5
Solar trackers compared to fixed-tilt
Tracking increases the energy production of a
solar system by ~20%
Energy values increase due to alignment with
demand through broader generation curve
