The off-grid solar tracker EV charger is quicker and less expensive to install than traditional grid-connected stations and avoids costly utility demand charges since there’s no need for infrastructure.

An off-grid solar tracker powers this EV charging station

Dartmouth College in Hanover, New Hampshire, has installed an off-grid solar tracker EV charging station for its employees.

“This solar electric vehicle charger is a part of the college’s efforts to make our [transportation systems] more sustainable”, said Marcus Welker, assistant director of sustainability at Dartmouth College [via Vermont Biz].

Solaflect Energy, based in Norwich, Vermont, designs and manufactures the Solar EV Charger. The four Level 2 charging points are powered by a 6.2-kilowatt solar array mounted on a dual-axis tracker that generates 40% more power than comparable fixed panel arrays.

Solar panels are often tilted to a stowed position to prevent wind damage to utility-scale assets. Array Technologies introduced a passive stowing strategy that prevents unnecessary production losses.

Passive solar tracker wind stowing boosts energy production

During high wind events, utility-scale solar assets are often automatically tilted to a stowed position to prevent damage and downtime from repairs. High wind can cause solar panels to vibrate and rotate, leading to microcracking, twisting, or shattering of panels.

However, stowing solar trackers can lead to a loss of production as they do not follow the sun in an active stow system.

Array Technologies, a leading provider of solar tracker systems, worked with independent engineering and design firm DNV to study an alternative method to active stowing called passive stowing. The analysis focused on evaluating the energy losses associated with various tracker wind stow methods and considered multiple variables, including wind velocity stowing thresholds, wind direction, dwell time, stow exit wind velocity threshold, stow angle, and stow direction.

The use of modern technology in pv modules has made solar trackers indispensable, ensuring optimal energy output regardless of geographic location.

Solar potential of tough terrain

Solar tracker adoption has picked up significantly in Indian PV installations. What are the key growth drivers?

Solar trackers help in optimizing and increasing energy production while reducing costs. Single-axis solar trackers generate up to 20% more energy than projects which use fixed-tilt systems that do not track the sun’s movement depending on site conditions. 

The use of modern technology in photovoltaic modules has made solar trackers indispensable, ensuring optimal energy output regardless of geographic location. Bifacial adoption is encouraging. Due to improved tracker design efficiencies, there is an upward trend for adopting solar trackers combined with bifacial module technology in India.
