Built around the work.
Paid for by installers, not manufacturers.

Powerlily runs a solar company on one record: find the customer, design and install the system, then monitor and service it for years after the crew leaves.

The design starts a project record that stays with the customer.
Our starting point

Where it came from.

Powerlily began as the software behind WattsUp Solar, a solar installation company. The first questions were practical ones: how does the sold system reach the crew without being typed in again, and how does the office keep the customer informed while it happens?

Today Powerlily Inc. builds it for other solar companies, funded by the installers who subscribe rather than by manufacturers or lenders. Sales, design, the office and the crew work from the same customer and project record, and the installed system stays on that record after the job is complete.

How we build

Three rules we build by.

They hold for a new shading calculation and for a small fix to the crew’s schedule.

  1. Make the numbers checkable

    Editable geometry, per-panel shade and an 8,760-hour production simulation, so a designer can trace the production figures in the proposal back to the roof they came from.

  2. Keep it on one record

    The design, equipment, price, documents, schedule and customer stay on one record as the job moves from sales to the office to the crew. The crew opens the record the salesperson started.

  3. Stay close to installers

    What a setter, a designer or a crew captain hits on a live job sets what we fix next. Every release goes in the public changelog with its date.
