01 · The problem
Making solar understandable
Interest in solar energy is high, but the information needed to make a decision is often technical and fragmented.
We wanted to combine location, weather and roof details in one app and give homeowners a clearer picture of production, cost and potential savings. For off-grid cabins, the solution also needed to make appliance consumption visible.
Design question: How might we make a technical calculation clear enough to support a major decision?
02 · The process
Build, test, simplify
We worked iteratively and let user insight determine which details deserved space.
The team defined functional and non-functional requirements before narrowing the MVP to address lookup, weather data, solar yield and production estimates. Crazy 8s, wireframes and interviews helped us validate early concepts.
- 01Results needed plain language and visible context.
- 02Production, cost and savings should be understood together.
- 03Iterative testing helped remove unnecessary complexity.
03 · The outcome
Energy data made practical
The final Android prototype guides users from an address to production, financial and consumption estimates.
Charts and summary cards translate technical data into a format that supports comparison and decision-making, while the consumption view lets off-grid users explore how appliances affect their available energy.
