The Solar Plan Lab process

From your electricity use to a plan you can question, change, and share.

Solar planning should start with your home and your goal—not with a pre-selected equipment package.

Four stages

Each stage answers one homeowner question.

Deeper engineering detail appears only after the basic recommendation is understandable.

01▤

Start with energy use

Use a monthly kWh value, scan an electricity bill, or estimate from appliances. The goal is to begin with demand rather than a product package.

What Solar Plan Lab doesSolar Plan Lab converts the selected usage into a daily energy target and keeps the source visible so you know whether the number came from a bill, an estimate, or manual entry.

02⌂

Describe the home and goal

Choose bill reduction, backup, off-grid planning, or a phased build. Add location and simple roof dimensions.

What Solar Plan Lab doesSimple mode asks only for the details a homeowner can reasonably know. Technical assumptions such as losses and panel dimensions stay in Advanced view.

03▦

Review sizing, fit and compatibility

See the proposed panel count, inverter class, battery choice, roof fit, estimated production, and basic compatibility warnings.

What Solar Plan Lab doesThe recommendation explains why each major component appears. The design uses generic component requirements first; specific brands belong in the equipment-selection step.

Choose the build path

Review an editable phase plan before downloading anything. Build now, phase the project, or install only what currently fits.

What Solar Plan Lab doesThe final report can include the homeowner summary, phase plan, roof information, cost assumptions and technical notes. Verify installation-ready details with qualified professionals.

What you need to begin

Less information than you might expect.

Quick Start is intentionally built around details a normal homeowner can find without opening an inverter manual.

One normal electricity month

Monthly kWh is ideal. A bill or approximate monthly amount can help you get there.

Your main goal

Lower bills, backup power, mostly off-grid use, or a system you can expand over time.

Rough roof length and width

Enough for a first fit check. Detailed roof geometry can wait.

No account required

Build the first version in a few minutes.

If the result does not make sense, change it before you download anything.
