## Solvvy Launches 'Economic Impact Simulation Guarantee' in Collaboration with XSOL Co., Ltd.
Solvvy Inc. has announced that its 'Economic Impact Simulation Guarantee' service for residential solar power and energy storage systems has been adopted by XSOL Co., Ltd., and services have officially commenced.
### Reducing Uncertainty in Economic Benefits of Renewable Energy
In recent years, interest in residential solar power has grown amid rising electricity costs and increasing environmental awareness. However, uncertainty regarding whether systems will generate power as simulated, and whether the investment will be recovered, often acts as a barrier to adoption. This 'gap between expectation and reality' is a primary risk in solar power implementation.
### About the Economic Impact Simulation Guarantee
Solvvy's 'Economic Impact Simulation Guarantee' compensates for financial losses based on pre-defined conditions if a significant discrepancy occurs between the power generation simulation calculated at the time of system implementation and the actual power output.
### Service Details
This service targets residential solar and energy storage systems designed using XSOL's simulation software, 'XSOL NAVI.' It uses the projected annual power generation as the baseline to compensate for financial losses caused by differences between projected and actual values under specific conditions.
#### Guarantee Summary
- Guarantee Period: 5 years (no deductible)
- Maximum Coverage: Up to 3 million yen (including tax)
- Target: Residential solar power and energy storage systems with a module rated output of 20kW or less.
- Application Frequency: Can be applied once a year, up to 5 times in total, if conditions are met.
#### Main Coverage Areas
- Product defects of the target equipment
- Installation errors
- Instances where the target equipment fails to meet its original functions or performance.
*Note: Insufficient power generation due to installation errors is covered for 2 years post-delivery.
#### Main Exclusions
Natural disasters, theft, relocation, damages by animals or plants, consumables, software programs, power outages, shading caused by pre-existing or newly constructed structures, and power output reduction due to voltage output suppression.
Solvvy continues to strive for business growth by providing guarantee and after-sales services that deliver value to both operators and users.
