JobMargin

Job costing for solar installers

On a solar job, the equipment is bought up front and the margin is made in the field: how fast racking and panels go on, how long the lift stays, and whether interconnection drags. JobMargin keeps equipment and field costs apart, so the job’s real progress isn’t hidden behind the panel invoice.

When you pick Solar as your trade, JobMargin loads these cost categories for budgets, receipts, and job costs. You can rename or add your own at any time.

Bid line items use the units solar actually bid in: kilowatts (KW), each (EA), square feet (SF), and lump sum (LS).

Example: what a solar job looks like mid-way

Ballasted racking and about 560 panels on a flat roof. The racking is done, the panels are about 60% set, and the electrical tie-in is still ahead.

Panels and racking were bought up front, so they’re fully spent, as expected. Labor is 57% spent with the racking done and panels about 60% set, which is on pace. The lift rental, at 65%, is worth watching: it has to stay through the last 40% of the panels.
