Solar

Use more of the sun you already paid for.

Wattlark compares what your array produces with what it should, then moves flexible loads into the sunny hours so less is exported at a low credit.

What it does

Generation against forecast, hour by hour.

Four behaviours, each visible in the app and recorded in the household activity log.

Forecast versus actual

See every day against what the sky and the array should have delivered. Dips are flagged as weather or as possible faults.

Move load into the sun

Dishwasher, laundry, water heating and EV charging are scheduled into the productive window when you approve the plan.

Value export honestly

Export credit and avoided import price are shown separately, so you can see what a kWh is worth at each hour.

Array health checks

A slow drift in yield against forecast is raised as a suggestion to inspect the array, never as an alarm.

How it decides

Four steps, no black box.

  1. 01
    Model

    Array size, tilt and orientation produce an expected curve.

  2. 02
    Compare

    Metered generation is checked against that curve each hour.

  3. 03
    Plan

    Flexible loads are proposed for the productive hours.

  4. 04
    Approve

    You apply the schedule; each change is logged and reversible.

Live equipment connections are planned work. In the demo a simulation stands in for meters, inverters and chargers.

Questions

Plain answers.

Do I need a battery to benefit?

No. Scheduling alone moves use into sunny hours. A battery raises the ceiling.

Does it work with any inverter?

Live inverter links are planned work. The demo uses a simulated array so you can see the behaviour.
