Buying Guide: How to Choose a Solar-Ready Load Center
Key questions to guide your selection and ensure compatibility with your solar plans.
- What is my total service size and how many circuits do I need now vs. later?
- Is outdoor installation important for weather resistance and durability?
- Do I need plug-on neutral breakers and a fully distributed neutral bar for future PV connections?
- Will I connect PV via a sub-feed lug kit or directly ahead of the main breaker?
- Is underground feed acceptable, or do I need a surface-mounted solution?
- Are CTs (current transformers) required for my solar metering design?
- Which brand ecosystem do I prefer for future service panel upgrades?
- What is the compatibility with local electrical codes and utility interconnection requirements?
Frequently Asked Questions
- What does “solar-ready” mean in a load center?
It means the panel is designed to accommodate solar equipment, such as CTs, solar-friendly lugs, and provisions for PV breakers, without replacing the main panel.
- Do all solar-ready load centers support plug-on neutral breakers?
Most Schneider Electric models in this list include a fully distributed neutral bar to support plug-on neutral breakers, but verify model-specific features before purchase.
- What is the difference between underground feed and surface mount in solar-ready centers?
Underground feed centers are wired from underground conduits, typically outdoors, while surface-mount units are installed on the exterior wall or pad; the choice depends on site constraints and local code requirements.
- Can I add PV CTs after installation?
Yes, most solar-ready centers include provisions for field-installed CTs on the line bus to support PV interconnection, but confirm exact CT compatibility with the kit and bus arrangement.
- What should I consider when selecting space and circuit counts?
Balance current service load, future expansion plans, and the space needed for PV-related equipment to avoid overcrowding or rework later.
- Are there code or utility restrictions I should check before buying?
Yes. Title 24 compliance, NEC requirements, and your utility interconnection rules affect which panel configurations are permissible in your area.
