Electrical Panels

Panels are only capable of housing so much electricity at a time. Depending on several factors, adding a solar system can require an electrical panel upgrade (MPU).

• Panel Size: 100A, 150A, 200A, 225A, 400A and whether it is standard or “Solar Ready”.
• Brand: Jurisdictions may not allow certain brands that are no longer in business.
• Accepted Brands: Siemens, Square D, General Electric (GE), and Eaton. If not one of these, it will likely require an upgrade regardless of other factors.
• Location: Cannot be in a closet or other enclosure, under a patio, behind a gate or wall, etc. Jurisdictions may require relocation if not compliant.
• Inverter size: Needed is based on system size and determines whether an upgrade is needed.
• Condition: Age, configuration (no fuses), unpermitted breakers/electrical work, etc.
