Know the roof before the array

Roof condition, access, electrical work and approvals as part of the first conversation.

A proposal from Daylight is written to be compared: scope, allowances and schedule, each on its own line.

How a proposal is built.

We separate the scope from the allowances and the schedule, so you can see what a figure buys and what would move it. Permits, engineering and inspections are listed where they apply, never folded into a number you cannot check.

A RESIDENTIAL SOLAR PLANNING CHECKLIST
  1. Which items are allowances, and what happens when a selection exceeds one?
  2. How are permits, engineering and inspections shown in the proposal?
  3. What would change the price after the contract is signed?

Put this perspective into practice.

Each guide below covers what the service involves and the questions worth bringing to your site assessment.
