Home EV Installation Defense Calculator
A consumer advocacy web application that helps new electric vehicle owners calculate their home's electrical load capacity. It generates a standardized technical request-for-proposal to prevent local electricians from upselling unnecessary and expensive breaker panel upgrades.
Why this matters
You just drove your new electric car off the lot, excited about your sustainable purchase. The next step is getting a charger installed in your garage. When the local contractors arrive, they take one look at your basement wall and insist your aging breaker panel cannot handle the load. They hand you estimates exceeding two thousand dollars. You feel entirely at their mercy, completely unaware that inexpensive load management modules or lower-amperage circuits could safely solve your problem for a fraction of the cost. You need an independent technical baseline before you sign a binding contract.
- · Built for Recent purchasers of electric vehicles who live in older single-family homes and are gathering quotes for charging stations..
- · Most likely monetization: one-time.

Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Homeowners may be too intimidated by electrical work to trust a software tool over a licensed human contractor standing in their garage.
- 2Marketing costs to reach consumers at the exact brief window between buying a car and hiring a contractor might be prohibitive.
- 3Contractors might actively dismiss the generated reports, rendering the tool useless in practical negotiations.
