A first design you can defend

Example house: 4,500 kWh a year, gas heating with 18,000 kWh, electric car planned. Three variants, the same ladder planners build in their offers.

10 kWh battery. 11.7 kWp produce more than the house uses by day. With 10 kWh, self-sufficiency rises from 38 % to 64 %. 12 of 15 similar projects chose 10 kWh.

Example for illustration. Prices estimated from list prices including installation.

How each size is decided

Rules decide whether, similar projects decide how much, your catalogue decides which product. No battery or no heat pump can be exactly the right call.

Questions

Does planck replace my planners?

No. planck prepares the first design. Your planner checks every number, changes what they want and sends the offer.

Where do the sizes come from?

From signed projects of similar houses. An hourly simulation checks yield and self-consumption, and every size lands on a real product from your catalogue.

Can I use my own product catalogue?

Yes. Every size lands on a product you sell, at the tier you offer today.

How does Max reach my leads?

As a chat on your website, or Max calls the lead at a time they pick. Both ask the same questions and hand the notes to your team. Max tells every homeowner in the first message that it is an AI.

What does the homeowner see?

Only the offer and the options you release, for example battery on or off. The house data stays as your planner set it.

Can I cancel any time?

Yes, every plan is billed and cancellable monthly. The 14-day trial ends on its own.
