Solar project milestones and change control
Preserve the approved baseline while giving teams a reviewable path for the changes that occur between design and closeout.

Why this workflow breaks
Equipment, site conditions, engineering comments, customer requests, and field findings can alter an approved solar plan. If the original baseline is overwritten, teams cannot explain the effect on cost, schedule, permits, or customer commitments.
Solar1 starts by documenting the decisions and failure paths. Configuration follows only after the operating boundary is understood.
Workflow sequence
Keep the handoff visible from first review to accepted outcome.
- 01Identify a variance or requested change
- 02Describe the baseline and proposed revision
- 03Review affected disciplines
- 04Approve, reject, or return the change
- 05Update controlled downstream plans
What to configure
Specific controls, qualified by implementation.
Record proposed changes against the current approved baseline.
Route technical, commercial, inventory, permit, and schedule impact reviews.
Preserve the decision, revised scope, and downstream actions after approval.
Assessment output
A shared definition of the records, owners, and acceptance checks.
Records in scope
- Milestone
- Baseline snapshot
- Change order
- Equipment substitution
- Approval decision
Roles in the decision
- Project manager
- Design reviewer
- Finance reviewer

Checks before rollout
- Define which revisions need formal control.
- Agree on impact-review owners and decision rights.
- Test rejected, superseded, and urgent field changes.
Questions to settle
Questions to settle before configuring milestones and change control.
What should trigger a solar change review?+
Triggers may include scope, equipment, design, site, price, schedule, permit, interconnection, or installation-method changes.
Can a milestone be reopened?+
Your policy can permit controlled reopening while preserving the earlier completion evidence and recording why downstream work must be reviewed.
How do substitutions affect profitability?+
The review can route updated material and labor assumptions to finance before the revised scope is approved.
