TECHNOLOGY ASSESSMENT

Gen1 NEXTracker120

Horizontal Axis Solar Tracker NEXTracker, Inc.

Executive Summary

Issue: Revision D Status: Final

Date: August 10, 2015

Solar Proposal for Blue Sky Energy Partners (Sama' Solar LLC)

EXECUTIVE SUMMARY

DNV GL has been retained by NEXTracker, Inc., to prepare an independent technology assessment of the

generation1 (Gen1) NEXTracker120 horizontal axis tracker. DNV GL has studied documentation provided by

NEXTracker primarily regarding the technical aspects of the tracker product, but also including the

manufacturing, quality, and related business systems. DNV GL’s Key findings and observations from this

review are summarized below.

Company / Product history

The NEXTracker management team has extensive solar industry experience both individually and

working together as a team. DNV GL views the management of NEXTracker to have the skills and

leadership necessary for continued growth of the business and improvement of the product.

Installation of more than 262 MW, or roughly 10,000 trackers, in the first twenty two months of

operation is an impressive record for a new tracker provider. DNV GL views the comparatively large

quantity of trackers that have been installed in a relatively short period of time to be an important

basis for confidence in the future success of the NEXTracker product and the ability for the company

to deliver at a large utility scale.

Manufacturing / Quality

NEXTracker has the supplier infrastructure and management experience necessary to reliably

manufacture and deploy the NEXTracker120 product at commercial and utility-scale volume.

The selection of BCI as a manufacturing partner for steel components is an effective and appropriate

decision based on the current scale of the company. DNV GL observes that this partnership includes

BCI as a nearly integral aspect of the near term success of NEXTracker.

DNV GL considers the QMS manual to be a sound basis for continued development of the overall

quality management system, and the implementation of the PLM system, Arena, as a significant

enhancement of the NEXTracker capability for process control, records management, and product

consistency.

Each of the NEXTracker supply chain partners appear to have reasonable and adequate quality

management systems established for their areas of manufacturing competence.

Technology Overview

The Gen1 NEXTracker120 uses a “balanced-mass” design, a technically sound approach that should

offer certain advantages.

Each NEXTracker120 row is physically separate from adjacent rows, a configuration that has benefits

related to site layout and access between rows, but also the consequence of an increased number of

actuators and electronic components.

NEXTracker uses an in-depth approach to product and site design optimization. Each tracker row of

every project is optimized for local conditions including wind, snow, soil, and array layout.

Industrial lockbolts and structural blind fasteners are used to secure many of the structural

connections instead of bolts. DNV GL notes these fasteners have benefits including high strength,

vibration resistance, and consistent clamp force which should result in reliable, maintenance free

connections.


The tracker control system uses direct measurement of tilt angle for closed-loop positioning of each

tracker row, an approach that should provide comparatively high position accuracy.

Structural

Structural analysis of the Gen1 NEXTracker120 is consistent with the methods and requirements of

the International Building Code.

NEXTracker has conducted in-depth wind tunnel studies and structural analysis. DNV GL views this

work as an industry-leading effort that goes beyond the requirements of the code in a number of

critical areas and exceeds the typical standard of care applied to ground mounted solar structures.

NEXTracker has contracted with the wind research experts of CPP to conduct a site-specific wind

study for each project, a commitment that DNV GL views as a source of confidence in product and

site design optimization.

NEXTracker uses three unique stow strategies; exterior two rows at 30°, all rows at 30°, or all rows

at 60°. While novel, DNV GL notes the approach used by NEXTracker may provide more effective

high wind protection and a lower risk of dynamic excitation than conventional systems.

Controller

The GEN1 NEXTracker120 uses the P4Q SunTrack controller, an established product that has

reduced overall product risk during the early stages of new product introduction. DNV GL views the

P4Q controller and the embedded software as a source of confidence in the expected performance of

tracker products that use them, including the Gen1 NEXTracker120.

The P4Q control system has a range of signals available for remote condition monitoring including

direct measurement of tracker tilt angle, a capability that can be used to assess pointing accuracy,

proper functionality, and availability of each NEXTracker120 unit.

Installation / Operation and Maintenance

Installation process controls including, documentation, training, and on-site supervision are

adequate and sufficiently robust for commercial and utility scale installations.

The range and frequency of maintenance tasks required by the Gen1 NEXTracker120 is typical of

solar trackers. In practice, the NEXTracker120 may require less maintenance than comparable

trackers due to the use of structural lockbolts and structural blind fasteners that do not require re-

torque.

Warranty

DNV GL views the product warranty to be customary and appropriate to the industry.

Performance

Actual tracker position accuracy is very good, with errors of less than 1 degree demonstrated

throughout the day.

Reliability

NEXTracker has performed analysis of predicted reliability and a range of valuable accelerated life

tests. Since most NEXTracker projects are recently installed and records of demonstrated field

reliability, such as work order logs, service calls, and preventive maintenance records, have not


been available, DNV GL is unable to form a solid perspective on the expected reliability of the Gen1

NEXTracker120.

The NEXTracker120 has roughly ten times more actuators per MW than ganged trackers. In this

context, the lost energy impact due to failure of a single NEXTracker row can be an order of

magnitude lower than a typical multi-row tracker, assuming equivalent actuator reliability. On the

other hand, the increased quantity of electronics and actuator components used in the NEXTracker

system will increase the number of opportunities for potential failure to occur.

Regulatory

NEXTracker has followed appropriate steps to meet the regulatory requirements for solar trackers;

specifically, certification of the tracker structure to the grounding and bonding provisions of UL2703,

and structural design and analysis in compliance with ASCE 7 and the IBC.
