What Will Your Permit Office Ask For?
Most solar permits need two things: proof the roof can carry the panels (a structural letter or calculation) and an electrical plan showing how the system connects. EV chargers and batteries often need a load calculation to show the service can handle them.
New buildings and major remodels may also need energy code forms. Tell us your address and system size and we will confirm exactly which documents apply.
You Most Likely Need These If You Are:
- Installing rooftop or ground-mount solar
- Adding a home battery or backup generator
- Installing one or more EV chargers
- Upgrading a panel to support new loads
- Building a solar carport or canopy
- Submitting energy code compliance forms

Your Questions About Solar & EV Permits, Answered
Does my roof need an engineer for solar?
Many jurisdictions require a structural letter or calculation confirming the roof can carry the panels and racking. We review your roof framing and provide it.
Do EV chargers need a load calculation?
Often, yes – especially Level 2 chargers on older services. The calculation shows whether your existing service can handle the new load or needs an upgrade.
Do you work with solar installers?
Yes. We support installers with fast, repeatable structural letters and electrical plans. See our page for Solar & EV Installers.
Which codes do you use?
The NEC edition and building code your jurisdiction has adopted, including local amendments and utility requirements.
How fast is turnaround?
Typical solar letters and EV plans are quick turnaround. Your quote states the delivery date up front.
