Audience
Homeowners with solar panels considering a battery
The pitch
Housecell is a modular home battery you can start with one 5kWh unit and stack to four, with an app that shows the actual payback in pounds. The page is a bento grid where every tile is one number the buyer is trying to work out.
Sections it decided on
- Bento hero: payback tile, capacity tile, blackout tile
- Sizing: how many units your house actually needs
- Blackout behaviour and what stays on
- Tariff arbitrage: charging cheap, using expensive
- Installation: one day, MCS certified
- Warranty and the cycle guarantee
- Real numbers from four installed homes
- Book a survey
