For the 2nd TaiyangNews Market Survey on Solar Tackers, Ideematec provided data for its new products in addition to the two previously listed—a 1P variant of the previously listed L:Tec series, now presented as L:Tec 2P. Several of the listed specifications of these tools are the same except for those affected by the mounting configuration. First is size: the 1P tracker with a length of 240 m has room for 240 modules, while the 2P variant accommodates 360 modules in 190 m length, but doubles in width to 5 m to arrange modules in 2P. The other notable difference is while the latest 1P tracker can work both self-powered or on external AC power, the 2P tracker just relies on AC power from the grid. The rest of the specifications that are independent of module mounting configurations remains more or less the same. However, the L:Tec series as a whole is different to the company's other product series H4Plus, which like the other two is built on an independent row architecture. It can accommodate 360 modules in a 2P configuration, while also supporting 4 modules in a landscape layout, an option that was also offered with the L:Tec previously. The dissimilarity between these two product groups starts from the drive system. The L:Tec works with sprocket wheels and the H4Plus works with steel ropes. All Ideematec systems come with the company's signature decoupled drive technology, i.e., the drive tube is mounted more than 1m below the module surface. It allows for fewer foundational posts and ensures that forces on the drive are kept to an absolute minimum, prolonging the lifetime of the system and eliminating unnecessary downtime for maintenance or repair. In case of H4Plus, each row of modules is driven by a universal shaft with fixed drive via posts and steel cables. The L:Tec platform couples a patented locking technology with the aforementioned decoupled drive technology. As a result, the system on the drive unit places its weight directly onto the foundations. This way, only 1.4% of the load from the table is passed on to the drive tube during tracking, while the rest is diverted to the post, according to Ideematec. In the end, this approach helps build long trackers.
While L:Tec systems come with a full-locking mechanism in every inclination, H4/H4Plus trackers work with a high eigenfrequency and high damping ratio. This patented tracking system uses steel ropes and eliminates the need for shock absorbers, which are sensitive to dust and sand. While both tracker series are bifacial compatible, the modules are only completely free from the backside when installed on L:Tec trackers.
In case of installations with H4Plus, there are rear profiles that slightly reduce the bifacial additional yield, which is still high due to the wide gap between the rear side of the module and the substructure.
Another difference between H4Plus and L:Tec is the number of tracker parts. L:Tec needs about 35% fewer parts compared to H4Plus, which means that installation times with L:Tec are significantly faster. Ideematec offers the market standard 10- year warranty for the structure and 5 years for the motor, while the warranty on electronics is limited to a duration of 2 years.
