The sun shows up every morning, on time, and it never sends a bill. Aster keeps some of it for you: on the roof, in the battery, and on the money you no longer pay.
Who it's for:
People who want the house to run on its own roof. Panels sized to a year of real bills, a battery that carries the evening, and one crew that designs it, installs it and answers when you call. Everything in one app: what the roof made, what the battery holds, what the house used.
The roof works by day. The battery works by night. Nothing to switch, nothing to remember.
Charged by noon
On a clear day the battery is full before lunch. The rest of the afternoon goes to the house and to the grid, and the evening runs on what was stored.

Book a roof visitPrograms
Homes, businesses and whole neighborhoods. Six ways to put a roof to work, each with the number that matters.
Panels sized to your roof and to a year of your bills, drawn one by one before we quote. A visit to the roof comes first, then the drawing, then the price.
Keeps the lights on after sunset and through outages, and lets the house use more of what the roof makes instead of selling it back for less.
Flat roofs, warehouses and offices, with the work scheduled around your opening hours. Every panel and every meter on one screen afterwards.
Shade for the parking lot and charging for the fleet, from the same structure. The roof of the carport pays for the chargers under it.
Subscribe to a local solar farm and see the savings on your own bill. For renters, shaded roofs and anyone who cannot put panels up.
Solar and storage that keep a clinic, a shelter or a fire station running when the grid is down, for three days without the sun.
Your roof isalready in the sun.
A drawing, a number and no pressure.
