Overview

• The SmartSolar tracking system was designed with the objective to cost no more than 15% of a fixed solar PV installation. This functional design will cost less than 150-200 US$/kWp

• The design uses slewing drives, the most reliable, proven technology available, used in both solar trackers and many other demanding applications.

• The purpose of this presentation is to let you know that solar tracking can & will come back!

Assembly System

May 2016

• The SmartSolar Tracker was designed for optimal cost, easy installation and high reliability, achieved by:

Custom adaptors to connect to standard, proven slewing drives

Custom enclosures for standard, proven self-aligning bearings

Laser precision cutting of all components

All-aluminum parts have the same expansion

The next sheets explain order & ease of assembly

The next steps

May 2016

• This functional design of the SmartSolar tracker is/will be presented to various advisors, suppliers, mechanical engineers and finally to mold designers.

• After review this will lead to a revised concept, followedby the final design of the molds for profiles, brackets and the bearing enclosures. This design and the strengthcalculations will be reviewed by our advisory board.

• Then a pilot production will be used for prototyping

• Finally the design will be offered for approvals to authorities in target markets.
