High Performance 2P Solar Tracker Self Cleaning
Working principle:
Single axis 2P solar tracker is a device that orients a payload toward the sun. It can track sun in east-west direction. It is suitable for lower latitudes with high sun height angle. Its power generation efficiency is 25% higher than fixed sun panel tracking. The solar tracking system can be installed at ground level or roof. Single axis solar tracker includes, mounting bracket for solar panel, horizontal shaft, rotation drive mechanism, wind speed detection device and tracking controller. Single axis solar tracker has one degree of freedom that acts as an axis of rotation. The axis of rotation of single axis trackers is typically aligned along a true North meridian. It is possible to align them in any cardinal direction with advanced tracking algorithm.

Functions:
1. Single row independent drive unit, no connection between row and row, to ensure convenient traffic between square array;
2. Adopt the form of self-power supply, without external power supply;
3. Independently developed MCU microcomputer control system;
4. Max terrain tolerance in N-S direction up to 15%.
5. Independent 2P module design, which reduces the quantity of posts and the installation cost significantly.
6. Free obstacles among trackers in N-S direction, easy to maintain and clean.
Advantage:
1: Less electric control and driving unit, lower failure rate;
2: Strong adaptability, simple installation, convenient operation and maintenance;
3: Tracker could adjusts solar panels into horizontal in strong wind condition.
4: More reasonable wind resistance design;
Through the wind tunnel test, a more reasonable wind resistance mechanism can be obtained, which can more effectively guarantee the 25-year life of the power station.
5. Minimum number of drives for every MWp installed.
6. Minimum energy consumption.
7. Compatible with different foundation solutions: ramming, micropiles, concrete pads, predrilling, screw pile.
8. Compatible with all PV modules (framed, glass-glass, thin-film, bifacial)
9. Preassembled joints and components.
10. High tolerances to foundation positioning error.
