How it works

Signature to switch-on, with nobody in between.

Six stages, one contract, and the same names on the drawing, on the roof and on the monitoring report.

Residential 6 – 8 weeks · Commercial 12 – 20 weeks

No subcontractors at any stage

The sequence

Six stages, in order

Durations below are residential. Commercial roughly doubles, and the variable is almost always the utility.

Week 1 – 2

Led by

Cascade design engineer

Survey & load profile

We climb the roof, run a shade study and pull twelve months of interval data from your meter. No price is quoted before this is done.

Roof structure and condition assessed

Shade study across every roof plane

Metered load profile, not an estimate

Led by

Licensed engineer, in house

Design & PE stamp

Drawings are stamped before a price is fixed — residential included, whether or not the jurisdiction asks for it.

Array layout and string design

Structural or ballast plan per building

Fixed price issued with the drawing set

Week 2 – 4

Week 2 – 8

Led by

Cascade permitting desk

Permits & interconnection

Filed on the first day of design so the utility clock starts as early as it possibly can.

Permit filed with your AHJ

Interconnection application submitted

98% first-pass approval rate

Led by

Cascade staff crew

Installation

Our own crews and our own stock. Never brokered to a subcontractor, in any of the twelve states we work in.

Same crew from start to commissioning

Roof access sequenced around your operations

Manufacturer-approved mounting details
