Maxi-Lock and Smart-Slope: automatic wind protection and full adaptation to slopes

We are introducing two new developments for our solar trackers, already available on the European market and applicable to both conventional PV plants and agrivoltaic projects: Maxi-Lock and Smart-Slope. Both were presented at Key Energy 2026.

Maxi-Lock: autonomous hydraulic wind lock

Maxi-Lock is an autonomous hydraulic mechanism, developed and patented by Alphatracker after two years of testing. It locks the tracker’s movement under strong wind gusts or high-amplitude vibrations, preventing axis displacement and eliminating aeroelastic instability effects. Once the event has passed, the system unlocks automatically, with no electricity or electronics required.

• Up to 60 % more PV modules per tracker.
• 20 % lower supply cost.
• 40 % less electronics and mechanical parts in the assembly.
• Adaptable to installations on steeply sloped terrain.

Smart-Slope: one tracker where two were needed

Installing trackers on terrain with sharp changes in slope conventionally forces the project to be split into shorter units, each with its own motor and control system. Smart-Slope solves this with a cardan-type mechanism that transmits movement along the tracker axis even when its sections are not perfectly aligned: a single tracker runs continuously where two were previously needed.

Since it requires no additional machining of structural components and clamps onto the axis, Smart-Slope can be installed at any point of the tracker regardless of the original design. The result:

• Complete elimination of additional motors and control systems.
• 50 % lower maintenance costs and failure probability.
• Higher plant availability.

Both solutions join our range of 1P, 2P and multi-row solar trackers. To see how they fit your site, start with a free preliminary design in MaxiDesigner.
