SaaS / Enegaeru ASP · Kokusai Kogyo

Make solar, batteries and all-electric homes easier to choose.

Compare rooftop solar PV, home battery storage and household electrification using Japan-specific tariffs, product characteristics and energy-demand assumptions.

Solar PV, battery storage and all-electric living in one proposal.

For homebuilders, installers and equipment brands, Enegaeru ASP evaluates rooftop solar, home batteries and household electrification together. Compare electricity purchases, solar exports and gas-cost changes, including relevant heat-pump water-heating and induction-cooking scenarios.

Start with one to twelve months of usage data, or estimate demand from electricity bills where supported. Apply location, lifestyle, PV orientation and capacity, the selected battery and tariff. Refine initial estimates as actual customer data becomes available.

The published ASP approach uses NEDO METPV20 irradiance data for 835 locations and JIS PV-generation calculations. Its battery master reflects usable capacity, charging and discharging limits, conversion losses and standby power, including differences between hybrid and standalone systems. Manufacturer-provided values and identified reference values support more specific comparisons than nominal battery capacity alone.

Published ASP features and technical basis (Japanese). Outputs are estimates under the stated assumptions.

Designed for your team’s work

Residential solar and storage manufacturers; installers; homebuilders; energy retailers.

What you bring

  • Location and household electricity use
  • tariff and equipment details
  • existing solar and export conditions
  • installation costs and financing assumptions

What you can evaluate or receive

  • Compare equipment combinations and electricity costs
  • explain self-consumption and export value
  • produce customer-facing economic assessments

A practical first evaluation

Start with one representative household and two equipment configurations. Check the assumptions your distributors will need to explain and the output your customer will receive.

Scope to confirm

The software supports economic evaluation. Site engineering, product certification, installation feasibility and future savings require separate assessment.

Before you commit

Can we use this as part of our Japan launch?

Tell us your customer segment, local operating model and first use case. We will discuss product fit and any additional data, integration, training or specialist work required.

Is the software or delivery available in English?

This page is an English introduction. Confirm interface, documentation, report and support languages for the product or engagement. Bilingual outputs and localization should be specified explicitly.

How are commercial terms agreed?

Request a quotation for the product, users or usage, data rights, scope and support you need. Confirm implementation fees, recurring fees, contract term and any project work before ordering.

Bring us the next decision you need to make.

Tell us what you want to launch in Japan, who will use it, and where the work is getting stuck. We can discuss the right combination of software, APIs, data and specialist support.
