Beyond the Installer Network: How a Residential Battery Manufacturer Used Market Research and Strategy Advisory to Diagnose a Stalled Attach Rate and Rebuild Its Go-to-Market Approach

Residential battery storage sits downstream of a sale that has already happened — the solar panel installation — which makes its commercial dynamics fundamentally different from most consumer hardware categories.

The client had built a technically strong battery product with competitive economics on a cost-per-kilowatt-hour basis.

Nobody at the company had systematically examined an alternative hypothesis: that the plateau had less to do with what customers were willing to pay and more to do with whether installers were actually presenting the storage option with confidence and competence at the point of sale.

Key Challenges

• No independent market research on the actual drivers of residential battery attach rates
• No structured understanding of how installer sales process maturity, training quality, and incentive structure correlated with attach rate performance
• No geographic benchmarking showing whether attach rate dynamics in incentive-rich markets differed meaningfully from those in markets without storage-specific subsidies
• Limited visibility into how competing battery manufacturers were supporting their installer channels and whether enablement investment was producing measurably different attach outcomes
• A commercial strategy defaulting to price competition as the primary lever, despite no clear evidence that price was the binding constraint
• Board pressure to identify a credible path to higher attach rates without entering a margin-eroding price war the company’s cost structure could not sustain

In channel-dependent hardware categories, the assumption that price is the primary barrier to adoption is frequently wrong — and frequently convenient, because it allows a company to avoid examining whether its own channel enablement investment has kept pace with the complexity of what it is asking installers to sell.
