You know what?
A 2 ㎡, 330W photovoltaic panel,
One day generating 1.4 degrees of electricity,
510 degrees of electricity a year,
According to the calculation, 20 million ㎡ photovoltaic base,
Annual power generation is nearly1.7 billion degrees
(* Data source: the world's largest single agricultural and optical complementary power station)
If a substantial increase
the power generation efficiency of each photovoltaic panel,
The base will receive each year
Photovoltaic power generation 20, or even 4 billion degrees,
Plus thousands of large and small photovoltaic bases in China,
This surge of electricity,
No longer worry about air conditioning costs, factory power rationing.
In the onslaught of hundreds of billions of photovoltaic power generation,
Servo is playing an important role.
next, little o will talk to everyone,
How does the servo help?
Improve the power generation efficiency of each photovoltaic panel.
1. servo-assisted multi-wire cutting machine to improve yield
Photovoltaic version of the pieces of blue cells,
You don't look at it as a little clever, ordinary.
In fact, to produce this thin little piece,
And finally arranged in the above picture,
Must go through the "before-in-after" three processes.
Each process involves multiple operating points,
It is no exaggeration to say that it has passed three hurdles and cut six generals.
(* Main processing processes and equipment in photovoltaic industry)
Multi-wire cutting machine is in
An important operating point in the previous process,
The main function is to turn the silicon rod ↓
Cut into silicon wafer ↓
In the process of operation,
Multi-wire cutting machine reel, lifting table, swing cylinder, etc,
As long as there is a slight error between them,
are likely to lead to uneven thickness of silicon, scratch defects,
Directly affect the conductivity of the final product photovoltaic.
Now, there are a lot of factories through,
High-performance servo drives and
High performance servo motor solutions,
Realize stable and reliable speed control of multi-wire cutting machine,
Positioning control, synchronous control and tension control.
This effectively circumvents the cutting process,
Disconnection, shutdown, excessive roughness and other process difficulties,
Greatly reduce the material loss in the cutting process;
Slice efficiency has also been greatly improved,
The number of single-blade films can reach more than 3700.
This greatly improves the cutting yield of the equipment.
2. servo assist sun tracking system precise sun tracking
In addition to the production process of photovoltaic panels,
In the process of using,
We can still see the busy figure of the servo.
For example, the day tracking system.
Photovoltaic panels in the process of receiving solar energy,
Base employees found out,
The position of the sun is constantly changing throughout the day,
Traditional photovoltaic panels are fixed position devices.
That is, when the sun is turned away from the photovoltaic panels,
Photovoltaic panels absorb significantly less sunlight,
As a result, power generation decreases.
Want to maximize the absorption of every inch of sunlight,
It's necessary,
to transform photovoltaic panels
A sun-chasing system with sunflower day-by-day characteristics.
(* Zhang Xingchao. Solar Panel Sun-tracking System Based on PLC [D]. Harbin University of Science and Technology, 2019.)
The sun tracking system is through two servos,
As the height angle of photovoltaic panels
and azimuth power source,
With sensor sensing angle change,
With the adaptive control algorithm,
In order to achieve photovoltaic panels
As the sun moves and turns,
Ensure that the sun is absorbed at all times.
Really.
An inch of time an inch of gold
Every inch in the board
All right, that's all.
Servo system in the application of photovoltaic industry,
A representative masterpiece.
I believe that with the popularity of photovoltaic,
and breakthroughs in motion control technology and
Under the relentless pursuit of engineers,
Servo will be more accurate, faster response,
Become a shiny photovoltaic industry
