## What is ArraySurvey?

Walk the roof once. Leave with the number.

ArraySurvey is a solar site-survey app built for the technician standing at the house. One job is one house, and across the top of it runs a rail of seven stops — Site, Roof, Shade, Layout, Electrical, Production, Proposal — in the order you walk the property. Each stop feeds the next, so by the last one the proposal is already priced.

SITE
• Customer, address, and who walked it.
• Tap "Use my location" and your latitude sets peak sun-hours, the best tilt, and the winter noon sun angle.
• Enter the electric bill — monthly amount, rate, kWh — and the app knows the yearly usage the design has to beat.

ROOF
• One card per roof plane, or a ground mount or carport.
• A roof canvas on a one-foot grid, ridge at the top. Type the eave width and eave-to-ridge depth and the plane draws itself.
• Drag the corners to cut hips and notches. Add a corner where the roof line turns; reset to get the plain rectangle back.
• Hold the phone square to the eave and the Compass button reads the plane's facing. Lay the phone on the shingles and the Level button reads the tilt.
• Pick the roof material.

SHADE
• Tap the roof to drop a vent, chimney, skylight, HVAC unit, tree, or dormer.
• Each one casts its winter-noon shadow band across the plane, drawn toward north from its height and your sun angle.
• Drag to move it, tap to change its size. Shade loss and usable area update live as a percent.

LAYOUT
• Choose the panel from the catalog, portrait or landscape.
• Set the fire setbacks — 18 inches at the edges and 36 below the ridge by default.
• The plane tiles itself with modules, skipping every cut in the outline and every keep-out around an obstruction.
• Tap a module to skip it; tap again to bring it back. Module count and kW show per plane and for the whole job.

ELECTRICAL
• Inverter type and model — string, microinverters, or hybrid — plus optimizers, battery and unit count, racking, DC and AC disconnects, and a production meter.
• A string plan for every plane from the NEC 690.7 cold-day and hot-day temperature math: the fewest and most modules a string can carry on that inverter.
• The service panel: bus rating, main breaker, open spaces, meter location, and a photo of the panel label.
• The 120% rule (NEC 705.12) checked against the PV breaker the design needs — and when it fails, the fixes: derate the main, a supply-side tap, or a bigger bus.

PRODUCTION
• Kilowatt-hours per year, with a 12-month bar chart underneath.
• A per-plane breakdown showing each face's orientation factor and shade loss.
• Production against the bill, the yearly savings, and the payback in years, with a derate slider for a conservative estimate.

PROPOSAL
• Equipment at catalog price, labor by the watt, permits, your margin, the federal tax credit, net to the customer, and the price per watt.
• A plain-English review list with NEC references — good, look again, or fix before permit.
• A proposal PDF on your letterhead: three headline numbers, each roof plane drawn with its modules, the month chart, the price table, and the review list.
• Mark it sent, mark it won, and send the awarded job to ProjectLead as one file — roof planes become plan images and strings become line items.

SUN TOOLS
Four standalone calculators for when you only need a number: a string sizer, a 120% rule check, sun-hours by latitude, and winter shadow length.

ON YOUR PHONE, AND ONLY THERE
Photos tagged to a plane, job notes, and a one-file backup of the whole job. No account, no sign-in, no server — the job stays on the device you surveyed with.

THE PLAN
Three jobs are free forever, and a job you already made never locks. ArraySurvey Pro, monthly or annual, opens unlimited jobs. A Low Volt Labs suite plan opens this app and the rest of the family.

Built for the residential solar installer who does the survey, the design, and the sale in a single visit.
