Message from the President

We have established a new formation to expand energy solution business in the continued pursuit for perfect-fit solutions for our clients.

Hiroshi Sasaoka

On April 1, 2018, Sharp Corporation transferred a part of its energy solution business to Sharp Energy Solutions Corporation (SESJ), a wholly owned subsidiary dedicated to the category, allowing more flexibility to meet customer needs with accuracy and promptitude, and covering every relevant activity, from development and marketing to installation and after-sales service, in Japan and abroad.

As an example in the area of residential homes, our accumulated knowledge and creativity help us to stay one step ahead of today‘s needs for self-sufficiency in renewable energy, creating Smart Homes that integrate “people-oriented” IoT appliances with energy solutions.

In the field of industry, we are transitioning to a highly specialized, professional organization that can create new business models providing peak-cut systems and virtual power plants (VPPs) that reduce electricity costs by effectively linking solar power generation with storage battery technology.

Furthermore, we are aggressively taking part in the construction of mega-solar plants and large-scale roof-top solar installations, in efforts to contribute on a large scale, to the deployment of renewable energy.

Your continued support and cooperation in our business activities would be highly appreciated.
