Solar, battery, heat pump and car. One plan.
Run your home
on the sun.
Dayhouse puts everything that makes or uses power in your home on one plan, and decides every minute where that power comes from. Most homes cut their energy bill by three quarters.

06:30
Warm before you wake.
The heat pump warms the house on power the battery bought at 2 a.m. for 9 cents, not the 24 cents the grid wants now.
10:30
The roof takes over.
By mid-morning the sun runs the whole house, and everything left over goes into the battery.
13:00
Chores wait for the sun.
The dishwasher and the hot water run at midday, when the roof makes more than the house can use. The battery is full, so the rest is sold.
18:30
Peak price, no grid.
From 5 to 9 p.m. power costs 36 cents. Dinner, the heating and the lights all run on the battery instead.
01:30
The car charges while you sleep.
At 9 cents a kWh, the cheapest hour of the night. It's at 86% by 4:30 and the battery tops up for the morning.

Hardware
Four parts, designed to work as one.
Made for the side of a house and twenty years of weather. Each part talks to the others every few seconds, so the plan is always the whole home, not one gadget.
Dayhouse Cell
A wall battery the size of a narrow bookcase. It fills from the roof or the cheapest hours of the night.

Dayhouse Air
A quiet heat pump that heats the house and the hot water, and does most of its work when power is cheapest.
- Efficiency

- Sound

Dayhouse Charge
Tell it when you leave. It finds the cheapest hours before then, or charges from the roof if the car is home.

- Cable
- 7.5 m, tethered
The grid
142,000 homes.
One power plant.
When the grid runs short on a winter evening, Dayhouse batteries can answer together in under a second. Owners choose how much to lend, and they're paid for every kWh.

Questions people ask
What happens in a power cut?
The Cell keeps your lights, fridge and internet running on its own. A full battery covers a typical evening and night.
Does it work in winter?
The roof makes less, so the plan leans on cheap night power instead: the battery and the heating fill up in the cheapest hours and run through the day.
Do I need all four parts?
No. Each works alone. Homes with a roof and a battery save the most per euro; the heat pump and charger add the most when you replace gas or drive a lot.
Who installs it?
A certified local installer, booked and checked by us. You get one price, one warranty and one number to call.
What do I get paid for helping the grid?
You choose how much of your battery to lend. Homes on the default setting earned €210 on average last winter. Illustrative.
