The most frustrating expense for photovoltaic workers is often invisible.
The same set of power generation data needs to be reported to the power grid for compliance and transmitted back to the backend management and operation, but in the end, two sets of equipment and two SIM cards need to be installed. The cost is doubled, the energy is doubled, the power station is generating electricity, but the money is quietly slipping away.
In today’s rapidly expanding distributed photovoltaic industry, many investors and operation and maintenance teams share the same feeling:
The inability to increase the revenue of power plants is often not due to insufficient lighting or poor equipment, but rather due to a large amount of unnecessary hidden costs.
Especially when it comes to data transmission, almost everyone is in pain, but few people explain it thoroughly.
Common challenges in the industry:
One piece of data, neither end can be lost
Firstly, provide compliance data for the power grid.
The power generation, voltage, power, and equipment status must be uploaded in real-time and stably. Once there is an interruption, delay, or packet loss, it may trigger a compliance warning, affecting grid integration assessment and subsidy distribution, and no carelessness is allowed.
The second is to provide one’s own operation and maintenance data.
How much electricity is generated every day, whether the equipment is abnormal, and whether maintenance is needed must be clearly seen. Otherwise, even if the power station is shut down, it cannot be detected in a timely manner, and a reduction in power generation by one degree is a tangible benefit.
The same data needs to be transmitted from both sides, and neither side can be disconnected.
This seemingly simple requirement has become a pain point that the industry has long struggled to solve perfectly.
Reality dilemma:
Dual devices+dual SIM cards, double the cost and energy consumption
In order to meet both grid compliance and autonomous operation and maintenance, the industry can only use the most “stupid” solution in the long run
Two independent transmission devices+two communication SIM cards
One link is dedicated to connecting with the power grid, and the other link is dedicated to serving the operation and maintenance backend.
The following problems are obvious:
-High costs: Hardware procurement, installation and debugging, and communication fees are all double expenses, and long-term operation is a heavy burden;
-Operation and maintenance are extremely complicated: two systems are checked separately, with multiple fault points and slow localization, resulting in a significant amount of manpower and energy being wasted;
-Stability is difficult to guarantee: with multiple links and nodes, it is more prone to disconnections, lagging, and data confusion, which not only affects compliance but also delays management.
Many power plants appear to be operating normally, but in fact, they have been silently paying for this kind of ‘redundant construction’.
The traditional plan is patched up and patched up, but it never breaks out of the vicious circle
In the past, the industry has also made many optimization attempts, but most of them were just minor fixes on the original framework.
Merging interfaces, simplifying wiring, optimizing operations… The underlying logic of “dual devices, dual links” has not yet been shaken off.
The result is:
The problem still exists, the cost is still high, and the operation and maintenance are still complex, but it has changed from “difficult to use” to “barely usable”, and has not been fundamentally broken.
One send, two receive, solve complex problems in the simplest way possible
Its core logic is very straightforward:
One data, one collection, synchronous bidirectional transmission, two channels are independent of each other and do not interfere with each other.
No need for two sets of devices, no need for two SIM cards,
Only one set of intelligent terminals is needed to simultaneously achieve:
Stable data upload to the power grid, firmly guarding the compliance bottom line;
Real time data is transmitted back to the operation and maintenance platform, providing a clear understanding of the power station’s operational status.
Compared to traditional models, the advantages are clear at a glance:
-Directly halving hardware and communication costs
-Operation and maintenance have been greatly simplified, with fewer faults and faster troubleshooting
-Data transmission is more stable, secure, and compliance is more guaranteed
-Power station operation is more worry free and revenue is more controllable
Compliance is the bottom line, revenue is the goal,
The power station should not have been continuously paying for redundant construction.
One shot, two harvests, solved complex problems in a simple way.
In conclusion
The key to the rapid recognition of the industry for the dual income policy is that it truly stands from the perspective of operators, simplifies complex problems, and minimizes ineffective costs.
At present, multiple photovoltaic companies have launched a “dual generation” solution, which effectively solves the long-standing pain points in the industry.
The significance of technological upgrading is never about showing off skills, but about making power plant operations simpler, more cost-effective, and more worry free.
And dual generation is an important step towards refined operation of distributed photovoltaics.
