The Launch of Sarareko Simple Diagnosis: Japan's First Solar Power Simulation Tool

In a significant development for renewable energy in Japan, Enabank, a company focused on energy procurement and decarbonization support, has launched Sarareko Simple Diagnosis. This simulation tool is designed to evaluate the economic benefits of self-consumption solar power systems and is the first of its kind in Japan. The tool operates within Enabank's platform, Enepark, and offers businesses the ability to assess the potential for solar power implementation based on various installation methods.

Overview of Sarareko Simple Diagnosis

Sarareko Simple Diagnosis is a free feature that allows users to easily simulate the installation potential of self-consumption solar power. By merely providing details about the installation site such as 1) location, 2) shape of the site, 3) electricity contract plan, and 4) electricity usage data, users can quickly generate simulations. Although it is user-friendly in approach, leveraging actual location data and electricity contract specifics ensures a high degree of accuracy in the simulation results.

Key Simulation Outputs

Upon completion, users receive a variety of valuable insights, including:

• - Installation Potential

- Capacity to be installed
- Annual self-consumption volume
- Annual electricity cost savings
- Annual CO2 reduction

• - Economic Effects of Ownership

- Estimated installation costs
- Payback period of initial investment
- Cost of electricity generation over 30 years
- Total cumulative cash flow over 30 years

• - Economic Effects of Leasing

- Annual leasing costs
- Length of leasing agreements
- Cost of electricity generation over 30 years
- Total cumulative cash flow over 30 years

• - Economic Effects of PPA

- PPA unit price
- Duration of PPA agreements
- Cost of electricity generation over 30 years
- Total cumulative cash flow over 30 years

This unparalleled capability in simulating the economic benefits of ownership, leasing, and Power Purchase Agreements (PPA) distinguishes Sarareko from other solar simulation services available in the Japanese market.

Benefits of Using Sarareko Simple Diagnosis

Utilizing Sarareko Simple Diagnosis enables companies to quickly gain insights into the feasibility and economic advantages of solar installations during the initial stages of assessment. This tool is particularly beneficial for businesses with multiple locations, as it aids them in identifying the potential for self-consumption solar power and prioritizing installations effectively. Moreover, should the results indicate a viable opportunity, businesses can seamlessly transition to more detailed analysis using Sarareko's solar power installation support service, which encompasses everything from comparison to selection of installation companies.

Development Background

In recent times, an increasing number of corporations are considering the installation of self-consumption solar power systems to mitigate risks associated with fluctuating energy prices and to aid in decarbonization efforts. However, before Sarareko, companies faced significant difficulties estimating installation costs and potential economic effects at the preliminary evaluation stage. The absence of accessible simulation methods meant that assessments often required several weeks to receive estimates from solar installation companies after collating necessary documents like building plans. This lengthy process meant investments in time and effort often culminated in discovering that solar installation was not a feasible option.

Comprehensive Energy Insights

Sarareko's development underscores the industry's need for expertise in both solar power generation and electricity consumption behaviors. Simulating how much electricity can be self-consumed necessitates understanding not only solar panel productivity but also the specific energy contracts in place, further complicating assessments. Enabank’s unique position in the market provides comprehensive insights by leveraging knowledge from both solar installation and electricity retail sectors, enhancing the accuracy and breadth of Sarareko's simulation capabilities.

Future Developments

Enabank is committed to the continued enhancement of Sarareko Simple Diagnosis, with planned updates including battery storage simulation functionalities. Future releases may include API access for the tool and even more sophisticated simulation services aimed at installation companies. Through these initiatives, Enabank seeks to standardize solar power simulations, empowering companies to make informed decisions regarding their energy strategies.
