Helio
I like how Helio keeps its pitch to a single sentence. Know exactly what your rooftop solar made today. That's the whole product in a nutshell, and it's exactly the missing piece for thousands of homeowners staring at confusing inverter readouts or waiting for a monthly bill to tell them something.
The solar industry spent years selling panels and tax credits, but the daily feel of generating your own power has been underdelivered. A simple number on your phone that says you made X kilowatt-hours can change how people talk about their system, and it can nudge behavior like shifting laundry loads into sunny hours. That's sticky.
I'd want to know how it handles cloudy days or shading, and whether it pulls from the inverter, the meter, or its own hardware. But the premise is solid, and it points to where solar is heading. The big players are fighting over panels and pricing; the durable edge is helping people feel their system working day to day. Helio wants to be that layer, and I'm curious to see how it holds up.
