PV Electrical Plans
The electrical drawing set your reviewer actually checks.
One-line diagrams, string sizing, conductor schedules, grounding and rapid shutdown — every electrical detail of your solar system drawn to NEC requirements and matched to the equipment you install.
What's in the set
Every electrical sheet, planned before the first conduit.
String sizing & voltage calcs
Cold-weather and hot-weather voltage limits, current per string and inverter window checks documented.
Conductor & OCPD schedules
Wire gauges, conduit fills, breaker and fuse ratings tabulated for the reviewer — no assumptions left in the field.
Grounding & bonding
Equipment grounding conductor, bonding jumpers and array grounding details called out at every connection.
Rapid shutdown
NEC 690.12 compliant shutdown details for residential and commercial systems.
Interconnection details
Supply-side and load-side connection details coordinated with the utility and AHJ requirements.
Electrical sheets
What each sheet shows.
The exact sheet list depends on your system, but these are the standard sheets in a PV electrical set.

Built from your equipment, not a template.
Module datasheets, inverter specs, mounting system and service panel ratings all feed into the drawing. That is what keeps the set consistent when the reviewer asks for the calculation behind a specific breaker.
- Module and inverter datasheet values used directly
- Existing service panel and busbar ratings verified
- Battery / ESS wiring coordinated on the same one-line
- Comments from a prior plan check addressed explicitly
