To the highest value of "Repowering" with Power Optimizer! Increase “profitability of remaining FIT period”
With some photovoltaic power plants reaching their 10th year in operation, there is growing interest in power conditioner replacement. What kind of inverter should be selected to increase profitability during the remaining FIT period? The keyword is "repowering".
not just a replacement
with the latest repowering
Increase power plant profitability
Ten years have passed since the start of the FIT system, and many of the industrial solar power plants that were built early are facing the time to review their power conditioners. In the review, we would like to consider a wide range of options, including not only repairing existing inverters and replacing them with successor models, but also replacement with other companies' products that can be expected to generate more power. Under such circumstances, in order to increase profitability during the remaining FIT period, it is desired that the power conditioner be directly linked to the performance improvement of the power plant, that is, "re-powering".
On the other hand, some power conditioner manufacturers have withdrawn from the Japanese market, and many power plant owners feel uneasy about the timing of the review. Some manufacturers are concerned about future business continuity, and the selection of power conditioners has become a major issue for power plant owners.

With module-based MPPT
Significant increase in power generation
It is also possible to reduce O&M costs
Under these circumstances, attention is now increasing to SolarEdge power conditioners. SolarEdge has long gained a global reputation for its installation in new power plants, but the company's systems equipped with MLPE (*) technology were also ideal for repowering existing power plants. The reason for this is the unique power control system that comes with a "power optimizer". A power optimizer is a DC/DC converter that connects to a solar cell module and achieves MPPT (maximum power point tracking) for each module.

Shinichiro Tanizaki, general manager for industrial use at SolarEdge Technology Japan, says that repowering with the company's system has four advantages.
"The first is 'increase in power generation by module-level MPPT control.' Conventional power conditioners have a limited number of MPPTs, but in our system, the number of power optimizers is the same as the number of MPPTs. .
The second is "safety". Even if it is submerged in water or a fire occurs, the power optimizer ensures safety, so the damage will not spread.
The third is about "O&M". Since it is possible to collect and monitor data for each power optimizer unit, it is possible to identify problem modules without going to the site while staying in the office.
The fourth is "ease of design". The string configuration will need to be changed for repowering, but the design at that time is extremely easy and can be used with any existing system.”
SolarEdge repowering works regardless of the size of your solar power plant, from low voltage to high voltage to extra high voltage. Whether your existing power conditioner is centralized or distributed, you can benefit from each. If you're looking for the highest level of repowering efficiency, SolarEdge's power conditioning system is definitely an important choice.
