Engineer-led support in Japan

English-speaking solar PV and EV charger support in Japan

I-S3 helps expatriates, international families, foreign-owned businesses, schools, diplomatic and US military-related customers understand and move forward with solar PV, EV chargers, batteries, O&M and energy data projects in Japan.

For international residents

EV charger installation, residential solar PV, batteries and electricity-use questions can be explained in plain English, including Japanese utility and site-survey requirements.

For foreign-owned businesses

Factories, warehouses, hotels, schools, offices and retail sites can discuss self-consumption solar PV, demand trends, O&M and EV charging with technical context.

For distributed sites

For sites outside Gunma and Kanto, we can combine remote design support, data review and trusted local coordination where appropriate.

Our work is not limited to translating sales material. We aim to make Japanese technical, utility, construction and scheduling matters understandable enough for customers to make a confident decision.

Start with a question, a photo, or demand data

For solar PV and self-consumption projects, 30-minute demand data is helpful, but an initial discussion can also begin with annual or monthly electricity usage, business type and site information. For EV chargers, photos of the parking area, distribution board and service entrance can speed up the first review.

Good first messages

  • "I need an EV charger at my house in Japan."
  • "Can you review electricity use for a factory or store?"
  • "We need English explanation for a solar PV project."
  • "We have a site near a US base / international school."
