SunHaus
Product Design
SunHaus is a solar setup assistant concept. It helps a household move from a general concern about unstable power to a clearer understanding of the setup their home would need — before any technical decisions are made.
Problem / Context
Planning a solar system usually begins with technical language — capacity, inverters, panel counts. For most households that vocabulary sits far away from the actual question, which is simply whether the things they use every day will keep running. The gap between the question and the jargon is where people stall.
Opportunity
Instead of forcing people to understand solar specifications first, the experience starts with things they already understand: their home, their appliances and their priorities. Technical translation happens underneath the interface, not in front of it.
Design approach
The flow moves progressively from household context toward a recommendation. Each stage collects one kind of understanding — motivation, personal context, then concrete appliance priorities — so by the time a setup is suggested, it is built from familiar choices rather than technical ones.
User journey
Four screens carry the household from motivation to personalisation: frame the need, make the value concrete, begin understanding the home, then capture the appliance priorities a recommendation is shaped around.
01
Household / Entry
The opening screen anchors the product in a feeling rather than hardware — “Stable power should feel normal.” A dark home with a single lit window makes the problem visible, and one action, Find My Setup, offers the way in.
02
Personalization
Before asking for anything, the experience shows what a personalised view looks like: battery health, monthly savings, generator strain and energy usage rendered as glanceable cards over a solar-roofed home. “Personalize My Setup” turns that promise into the next step.
03
Understanding the home
A quieter transitional screen explains why the product needs to understand the home first. It resets the pace and sets expectations for the input that follows, instead of dropping the household straight into a form.
04
Appliance priorities
Setup begins with a question in plain language: what appliances matter most? Each appliance carries its wattage, selection is visual and reversible with a live count, and “Step 1 of 3” frames the effort ahead — turning household priorities into the inputs a tailored recommendation is built from.
Key design decisions
Familiar before technical
Homes, appliances and priorities lead; specifications are inferred from them rather than demanded upfront.
Progressive commitment
Each screen asks for one small step — find, personalize, analyze, select — so the setup never feels like a single heavy form.
Value shown, not promised
The personalisation screen previews savings and usage before any input, giving the household a reason to continue.
Transparent effort
Step labelling, wattage on every appliance and a live selection count keep the process legible and easy to revise.
Final flow
Seen together, the four screens form one continuous path: from the emotional framing of stable power, through personalisation and home analysis, to the concrete appliance choices that shape a household's recommendation.
