Single Axis Solar PV Tracker Wind Protection
Working principle:
Single axis solar PV tracker is a device that orient the solar
panel toward the sun. Because solar trackers follow the sun, they
constantly should change their orientation throughout the day to
capture more energy.
In PV plant, solar trackers help minimize the angle of incidence,
which is the sunlight makes with a line perpendicular to the panel
surface. Minimizing the angle can increase the energy that the PV
plant produces.
Product info:
1. Intelligent control system. The biggest difference between the
solar tracker and the fixed bracket is that the tracker has a
movement control system. It is not only necessary to protect the
tracker, but also to track the sunlight according to its location.
At the same time, it is necessary to optimize and adjust it
according to different weather and seasons to ensure higher power
generation.
2. Advanced monitoring and operation system. After the hardware and
software of the tracker itself have enough stability, it is
difficult to encounter some extreme situations, such as hail in
some areas, so the monitoring system needs to inform the operation
personnel in time, so as to maintain and adjust the hardware and
software, so as not to affect the power generation.
At present, under the combination of excellent hardware and
software system, the excellent tracker can increase the power
generation by about 10%, which has made great contributions to
reduce cost and increase efficiency, and will naturally get the
attention of the market.
Advantage:
1. Tailor made tracker solutions to suit site requirement
2. Centralized astronomical tracker controller
3. Lowest energy consumption for tracking
4. Optimized for maximum yield within minimum area
5. Protection mechanism against specified wind speed
Functions:
1. System check function
Real-time display of the current working status of the system;
2. Power off protection function
The system data can be saved without loss after power failure.
3. Information collection function
Real-time acquisition of component tilt Angle; Real-time
acquisition of weather conditions, coordinate position, altitude,
time and other information;
4. Backtracking function
Reduces shading and maximizes power generation;
5. Night reset function
At night, the components are restored to the initial maximum wind
resistance state, and the errors caused by the day's operation are
eliminated to ensure the accuracy of the entire tracking system;
Business Scope:
1. Provide PV project related technical solutions to customers:
from early planning to designing, from installation guidance to
daily O&M, provide customers with complete technical support,
technical consultation and training;
2. Selection, designing, manufacturing and installation guidance of
the single-axis tracking system for PV power plant;
3. Complete supply chain of high-quality PV product components.
4. Research and development of emerging industries such as charging
and energy storage.
