Because of the low solar PV panel prices traditional solar trackers became too expensive relative to the installed cost. The "solution" was to stop using solar trackers in most cases. We believe the solution is to redesign solar trackers to make them economic in today's market. And that's what we did!

1. SmartSolar Tracking System

2. SmartSolarEnergyTechnology
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!

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, followed
by the final design of the molds for profiles, brackets
and the bearing enclosures. This design and the strength
calculations 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.
