Power Compensator System

 

 

 

Existing solar cell modules are affected by the solar cell module with the lowest output

(shadow section, etc.) due to the structural characteristics of the series and parallel connection,

and thus have limitations in leading the best efficiency of the photovoltaic system.

 

In other words, the existing systems are designed to be matched to the module with the lowest

power generation among the solar cell modules connected in series and parallel,

so the entire efficiency is reduced. 

 

This is also a very serious problem in terms of operation and management of the photovoltaic system.

 

 

 

 

 

 

 

 

 

 

 

Thanks to the Buck-boost of the power compensator, the power control of the converter,

and the MPPT tracking effect, our photovoltaic system also synchronizes the module output

value of the shaded part with the highest output value of the neighboring module,

so that the amount of power generated by each connected module reaches the highest point.

Therefore, it is an optimal system with a significant increase in power generation efficiency compared to existing systems.

 

 

- Increased efficiency by about 15-20% compared to the existing photovoltaic system

(Results of authorized agency testing) 

- It is possible to monitor individual solar module 

- Measurement of normal operation, lifespan, etc. 

- Reduction of installation conditions by using power reduction prevention technology for shaded areas.

- This is a technology for compensating for the consumption of power generation in the shaded section,

which is a factor inhibiting photovoltaic generation, through the fusion of new renewable energy fields and ICT technology.

We develop a power compensation device that can improve power generation efficiency.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The biggest problem with the existing photovoltaic device is the low amount of power generated in the shaded section.

To solve the problem, the system maximizes solar power generation efficiency 
by synchronizing the module installed in the shaded section with the maximum comparison output module connected to it

through a performance of impedance matching according to the micom control signal.
