A finished research run on an example topic, shown in full — the findings, the sources behind them and the product versions are all the run's own output, except that a product name may have been changed where it matched an existing brand.
A brand-agnostic web calculator where homeowners enter their critical circuits and get a recommended battery/inverter capacity in kWh.
01
What to build
MVP
A form-based calculator that takes appliance wattage and outage duration inputs and outputs a generic kWh sizing recommendation, similar to existing solar sizing tools.
Why it can be better
Faster and cleaner than scattered GitHub scripts, but still just outputs a generic capacity number like Unbound Solar or WattMath without checking it against any real product's specs.
Revenue model
Affiliate links to battery/generator retailers on the results page.
Target user
Homeowners researching backup power after a search for 'how much battery do I need'.
02
Context
The opportunity this answers
Build a brand-agnostic backup-sizing and load-matching advisor that recommends the exact battery, inverter, and panel setup for a specific home.
Why now
Backup brands have just pivoted from single-purpose portable power stations to whole-home marketing, splitting the market into incompatible tiers right as low-upfront-cost entrants like Base Power change the economics of adoption, so buyers face more confusing choices exactly when volatile, storm-driven search spikes push them to decide fast without any neutral way to compare branded tiers against their actual home loads.
