Solar-Ready Wiring: Why You Should Do It Before You're Ready for Solar
You don't need to be ready for solar today to benefit from solar-ready wiring today. The cost difference when other electrical work is already open is significant.
California's solar adoption rate leads the country, and West LA leads California. Whether you're planning solar now or in 3–5 years, getting solar-ready wiring installed during other electrical work is one of the highest-value incremental investments available — and the window to do it cheaply closes when the walls do.
What Solar-Ready Wiring Actually Is
Solar-ready wiring refers to the conduit runs and electrical infrastructure connecting your roof to your main panel — installed before any solar panels are purchased or mounted. This includes conduit from the roof penetration point to the panel, reserved space for solar circuit breakers, and appropriate grounding infrastructure. Done while other electrical work is already open, this costs $300–800 incremental. As a standalone project later: $1,200–2,500 or more.
The Panel Upgrade Connection
If you're upgrading your electrical panel — for EV charging, a heat pump, or aging capacity — you're in the ideal position to add solar readiness at incremental cost. The electrician is already at your panel, conduit runs can be added before walls are closed, and the new 200-amp panel provides the capacity a solar installation needs. Combining a panel upgrade with solar-ready wiring during the same project adds $400–800 to the total. As a separate project later: $1,500–3,000.
Battery Backup Pre-Wiring
Pre-wiring for battery backup can be added during any electrical project at incremental cost. A home pre-wired for both solar and battery storage is positioned to add either or both with minimal additional infrastructure when ready. In a West LA home that might sell in 5–10 years, this infrastructure can be a meaningful differentiator — solar-ready and battery-ready is an increasingly standard buyer expectation in this market.
California's Net Energy Metering 3.0 changed solar economics in 2023. Systems paired with battery storage now perform significantly better than solar-only systems. Pre-wiring for battery during your panel upgrade positions you for the optimal configuration.
The best time to wire for solar is when you're already doing other electrical work. The second-best time is right now. The most expensive time is when you've already closed up the walls.
