About Powerlily

Solar software should understand the whole business.

Powerlily is built alongside North American installers around a simple conviction: site geometry, engineering, the customer promise, field delivery and system ownership should remain one connected body of work.

How we build

Accuracy, continuity and installer reality.

The platform grows from three product principles. Each one matters on its own; together they explain why Powerlily reaches farther than a design tool or a generic CRM.

01

Installer reality

Build against the work as it is actually done.

Product decisions are tested against active solar workflows, where a small disconnect can become re-entry, delay or a promise the next team cannot keep.

Built around installed work The roadmap begins with how solar companies operate.
  1. 01.01

    Direct installer feedback

    Work with teams selling, designing, permitting, installing and supporting systems instead of treating each department as a separate buyer persona.

  2. 01.02

    Residential and commercial context

    Account for the different geometry, equipment, operating and documentation needs that appear across real project types.

  3. 01.03

    Field and office in the same loop

    Design for the crew at the site and the coordinator at the desk, with the project record bridging both views.

  4. 01.04

    Release against live workflow friction

    Prioritize improvements that remove actual handoffs, repeated work and uncertainty for teams using the platform.

02

Design precision

Make the production story inspectable.

The design engine resolves a changing three-dimensional scene into panel-level shade and production instead of hiding the result behind one array-level shortcut.

Panel-level shade The designer can see where the modeled result comes from.
A year of production The project story is built from panel-level hourly behavior.
  1. 02.01

    A full 3D obstruction scene

    Represent roofs, trees, dormers, vents, nearby structures and terrain as geometry that can affect the modeled array.

  2. 02.02

    Direct, diffuse and reflected components

    Treat beam occlusion, sky visibility and ground-reflected contribution as distinct parts of the irradiance calculation.

  3. 02.03

    8,760 hours per panel

    Evaluate a full modeled year for each module rather than applying one static production factor to the system.

  4. 02.04

    Interactive engineering feedback

    Refresh shade, production and related values as the layout changes so the designer can diagnose the result while working.

03

Platform continuity

Keep the model useful after the layout is finished.

The engineering becomes more valuable when commercial documents, permit work, field operations and customer ownership inherit it instead of rebuilding their own version.

One operating record The project remains useful before, during and after installation.
  1. 03.01

    The design supports the sale

    Carry the system, production, equipment and price into branded proposals and a controlled signing workflow.

  2. 03.02

    The design supports engineering

    Generate editable SLDs, plan sets and reports from project equipment, geometry and stringing.

  3. 03.03

    The project supports delivery

    Coordinate schedules, crews, customer communication, mobile execution and safety evidence around the approved work.

  4. 03.04

    The installed system supports the relationship

    Connect fleet data, the branded portal, lifecycle outreach and personal referrals back to the same customer record.
