[Decision-Making Survey] 'Explanatory Power' Is the Deciding Factor for Residential Solar and Storage Batteries
Goodfellows Co., Ltd. released survey results analyzing 2025 users of its 'Tainavi' platform. The findings reveal that the key to closing deals lies not just in price, but in 'clarity of explanation' and 'speed.' While 70% of contractors valued quick responses, the primary reason for stagnation was 'lack of explanation,' outweighing concerns over high prices.

Goodfellows Co., Ltd. (Headquarters: Shinagawa, Tokyo), operator of the residential solar and storage battery comparison site 'Tainavi,' has announced the '2026 Fact-finding Survey on Decision-making Among Residential Solar and Storage Battery Prospects.' This report analyzes survey data from 2,918 users of 'Tainavi' and 'Tainavi Storage Battery' collected between January and December 2025.
### Key Findings
The survey revealed that 22.1% of users who requested a quote (approximately 1 in 5) ultimately gave up on installation. Analyzing the factors behind successful contracts, 'clarity of explanation' was praised by 45.8% of those who signed a contract, compared to only 24.1% of those who abandoned the process—a nearly two-fold difference.
Furthermore, 69.8% of contractors valued 'speed of response,' highlighting that rapid response during the initial stages of high interest is directly linked to closing deals.
### Reasons for Stagnation and Abandonment
Among users still in the consideration phase, the top dissatisfaction was 'lack of explanation' at 24.7%, which surpassed 'high quote price' at 22.0%. This suggests that a lack of information for making a decision is the primary factor causing delays, rather than the price itself.
On the other hand, for those who abandoned installation, 'high quote price' was the most common reason at 25.9%. However, this group also tended to give low ratings for 'politeness' and 'clarity of explanation.' This indicates that abandonment is not solely a matter of price, but rather a failure to justify the value through effective communication.
As the bundling of solar power and storage batteries makes systems more expensive, the 'explanatory power' to convey technical details clearly has become a critical element in consumer decision-making.
