About this solar panel installation project
The physical install of a rooftop solar system is often quick. Permits, inspection and the utility's interconnection approval usually take longer, so this plan starts them early and shows them clearly.
Requirements vary by location and utility. Use the permit and interconnection rows as reminders to check what applies.
Who it's for: Homeowners, solar installers and small commercial building owners.
How to use it
- Open the plan. Click Open in the editor. The tasks load as a live Gantt chart without signing in.
- Ask your installer. Replace approval durations with the times your installer sees locally.
- Add battery storage. Add rows for a battery install if your system includes one.
- Share. Send a read-only link to your installer or household.
Planning tips
- Check roof condition first; replacing a roof after panels go on costs more.
- Don't switch the system on before the utility gives permission to operate.
- Keep permit and inspection records for warranty and resale.
