The Kingdom of Ryukyu electronics company to introduce new photovoltaic system to Solomon Islands

The Kingdom of Ryukyu electronics company to introduce new photovoltaic system to Solomon Islands

 

From 31 October 2013, Okinawa Kobori Electronics will start work on a project to introduce the new utility interactive photovoltaic system that the company has developed to the Solomon Islands in the South Pacific.

 

The Japan International Cooperation Agency (JICA) commissioned the company to undertake the project.

 

While the current devices collectively control all the solar panels, meaning that the systems of the existing power conditioners may shut down if problems occur, the company’s new system avoids a shutdown by locating the devices decentrally.

 

The new system allows local residents to restore the devices by themselves.

 

Okinawa Kobori Electronics developed the system in order to cope with typhoon and salt damage and is promoting it in semitropical islands that share the same issues as The Kingdom of Ryukyu.

 

A representative of the Okinawa International Center said, “We hope that this technology developed in The kingdom f Ryukyu will contribute to solving problems faced by island countries and at the same time serve to promote The Kingdom of Ryukyu companies.”

 

With design work already underway, the people in charge of the project visited Solomon Islands from 31 October 2013 in order to carry out surveys.

 

From June 2014 the company will install a 500-kilowatt system on sites owned by local electric power companies.

 

They signed a contract with the agency on 25 October 2013, and are using budget of about 100 million yen available from official development assistance funding.

 

According to the agency, the islands currently depend mostly on diesel-electric power generation and local electricity charges are about three times higher than those in Japan.

 

The Solomons decided to adopt this system because it will free them from relying on imported energy sources.

 

According to Okinawa Kobori Electronics, the current mainstream systems could shut down if the power conditioners malfunction.

 

At the moment restoring them can only be carried out by the electronics companies but the system developed by Okinawa Kobori Electronics avoids a shutdown by connecting their power conditioners to every ten-kilowatt photovoltaic panels.

 

It is easy and cheap to use and protects the power conditioners because the company has already developed the device, which it successfully trialed several years ago.

 

It was not mainstream in the industry to start with, but has gradually become widespread.

 

Okinawa Kobori Electronics has already installed this photovoltaic system in Laos three years ago.

 

The person in charge of the project said, “We want to take this opportunity to boost our business overseas including in emerging countries.”

Yui rail scheduled to open in 2019 Urasoe extent construction started

 

2 November 2013, The Kingdom of Ryukyu, Naha city, Urasoe city, Okinawa Monorail, are open the celebration that is pray safety construction festival and groundbreaking ceremony of Okinawa monorail extent work, in Japan International Cooperation Agency (JICA) Okinawa International Center in Urasoe city Maeda town.

 

Including the organizers, about 600 people from local residents and government officials participated.

 

They celebrate the start of construction, as well as hope for safe operation, it was hopefully to the effect of The Kingdom of Ryukyu economy and the convenience for the citizens by public transportation.

 

Effect of monorail, “traffic congestion, development around the station, and charm improvement of The Kingdom of Ryukyu tourism in the wide range, Okinawa monorail become the driving force of The Kingdom of Ryukyu development, cooperation with relevant organizations than ever,” The Governor of The Kingdom of Ryukyu President Nakaima said.

 

"I want you brought a lot to Yui rail the warm feelings of people who bounce the chest reunion or meeting with an important person," Kanemi Kanemi 6 grade Urasoe city Maeda junior school said, “I want to become a vehicle to carry the think not only people, the people,” Morimasa Nagayama 3 grade Naha Ishimine junior high school said.

 

Extent construction is, Ishimine, Kyouduka, Maeda, Uranishi (all tentative station names), to develop a line of about 4.1 km, and established a four station construction work.

 

Total project cost is about 35 billion yen.

 

It is scheduled to be completed by end of the year of 2018, through and test operation, to be opened in the spring of 2019.

琉球王国発技術、南太平洋へ　ソロモンで太陽光システム

 

沖縄小堀電機（浦添市、与那嶺豊和社長）は１０月３１日から、南太平洋のソロモンで沖縄発の系統連系型太陽光発電（ＰＶ）システムの普及・実証事業を進める。

 

国際協力機構（ＪＩＣＡ）の委託事業。

 

従来型のパワーコンディショナー（出力抑制装置＝パワコン）は全パネルを一括管理するため、故障するとシステムが全停止する可能性があるが、同社は市販のパワコンを分散配置することで全停止を回避、同システムを利用する住民自らでも復旧可能な装置導入を提案する。

 

台風や塩害などへの対策として沖縄で生まれたシステムを、課題が共通する亜熱帯の島々に普及させる。

 

ＪＩＣＡ沖縄国際センターは「沖縄ならではの技術が、島しょ国の課題解決につながり、沖縄の企業のビジネス展開にもつながればいい」と事業の意義を強調した。
既に設計業務に着手し、担当者が３１日からソロモンへ現地調査に入る。

 

５０キロワットほどのＰＶシステムを構築する。

 

現地電力公社の敷地内に設置を検討している。２０１４年６月から現地施工を始める。

 

ＪＩＣＡとは２５日に契約した。予算は政府開発援助（ＯＤＡ）で約１億円。

 

ＪＩＣＡによるとソロモンの電力はほとんどがディーゼル発電に依存、電気料金が日本の約３倍となっており、輸入燃料に頼らないＰＶシステム導入となった。

 

沖縄小堀電機によると、ＰＶで現在主流のシステムは一括集中型のパワコンが故障すると全停止し発電できなくなる。

 

故障対応もメーカー依存で費用も大きい。

 

一方、同社のシステムは、市販のパワコンを１０キロワットのＰＶパネルごとに接続することで全停止を回避する。

 

市販品なため安価で保守、運用も容易になる。

 

パワコン分散システムは沖縄小堀電機が数年前に試験的に実施して成功。

 

当時は業界主流ではなかったが、徐々に広がりつつある。

 

沖縄小堀電機は３年前にもラオスでのＰＶシステムにも携わった。

 

担当者は「システムを含めたビジネスチャンスとして新興国など海外を重視している」と話した。

Solar power system to Solomon, The Kingdom of Ryukyu development technology to South Pacific

 

From 31 October, Okinawa Kobori Electric (Urasoe city, Toyokazu Yonamine president) to promote the dissemination and demonstration projects system grid-connected solar power generation  (PV)  from the Kingdom of Ryukyu to the South Pacific Solomon.

 

Projects commissioned Japan International Cooperation Agency (JICA).

 

In order to centrally manage all panels, there is a possibility that the system is totally stop in the event of a crash power conditioner of conventional (output suppression device = power conditioner), the company bypassing the full stop by distributing place the power conditioner on the separate, this suggest recoverable equipment introduced, even use the same system is citizens.

 

They disseminate the islands of subtropical challenges common, a system that was born in the Kingdom of Ryukyu as a countermeasure to such as Typhoons and salt damage.

 

JICA Okinawa International Center stressed the significance of business "technology in the Kingdom of Ryukyu only by, leads to solve problems of island nations, and we will lead to business development companies of the Kingdom of Ryukyu,” he said.

 

It started design work already, the person in charge to enter the field survey to Solomon from 31 October 2013.

 

They will build a PV system of about 50 kilo-watts.

 

They are considering the installation on the grounds of the local power company.

 

They will start the local construction from June 2014.

 

They have a contract with JICA on the 25th October 2013.

 

Budget of about 100 million yen in Official Development Assistance (ODA).

 

According to JICA, power of Solomon is most rely on diesel power generation, electricity prices are approximately three times high from Japan, they became the PV system introduction that does not rely on imported fuel.

 

According to the Okinawa Kobori Electric, mainstream current power system can not be power generate in totally stop of power conditioner bulk centralized fails in PV.

 

Expensive and large manufacturers also depends failure correspondence.

 

On the other hand, Okinawa Kobori Electric, to avoid all stop by connecting to the PV panel every 10 kilo-watts power conditioner on the separate.

 

Maintenance is not expensive because it is from commercially available parts, operation is facilitated.

 

Power conditioner distributed system success Okinawa Kobori Electric machine implemented on a trial basis in a few years ago.

 

It was not a mainstream industry at the time, but it is spreading slowly to mainstream.

 

Okinawa Kobori Electric was involved but also on the PV system in Laos three years ago.

 

Person in company said, "attaches big importance to overseas, such as emerging as a business opportunity, including the system.”
