Rooftop solar co-ops that pay members back in kWh, not paperwork.

Execution — dated, unedited
JUL 07
Maya Chen

Second-city pilot is open. Also: started a first conversation with a hardware partner about co-designing the next metering unit. Early, but the shape is there.

Second-city pilot opened

Tainan cohort signed a letter of intent.

Tainan cohort signed a letter of intent for the second-city pilot. Different grid operator, so interconnect is a fresh fight — but demand travels.

Milestone
1,000,000 kWh tracked

Cumulative across the pilot co-op.

○ SELF-REPORTED

Crossed 1,000,000 cumulative kWh tracked. Number goes up, but the thing I care about is that zero members have asked 'where did my credit go' this month. The accounting is holding.

JUN 12
Maya Chen

First co-op is officially live in Taichung — 12 households on one array. Local paper picked it up. The founders of the building association are now our loudest advocates.

Hard week. Our metering integration broke twice and a co-op member churned. Wrote down exactly what failed so it can't happen at the next site.

MVP is live for the pilot group. Every member can open the app and see which kWh came off their own panels vs the shared array. Watching someone see their first credit land is the whole job.

Ran the demand survey properly this time. 40 owners, structured questions. The wedge is real: people don't distrust solar, they distrust the paperwork. That's the thing we're actually killing.

Validated demand with 40 rooftop owners

Door-to-door + survey across two Taichung districts.

Week 1. Knocked on 40 doors in Beitun. The pitch that landed: 'your roof already makes power — we just make sure you get paid for every watt of it.' 31 said tell me more.

Risks & challenges
01

If grid-interconnect approval stalls, license the kWh-accounting engine to existing installers instead of running co-ops directly.

02

Property managers of multi-unit buildings may sign faster than individual rooftop owners.

03

Competitive set: Sunrun, Community solar bonds. The wedge has to stay sharper than these.
