At Annex Solar, our team of expertise of electricians and installers are sent out to conduct a site survey. While our installers observe the roof for solar installation, our electricians check the main service panel to see if an upgrade is needed. If the main service panel upgrade is required and needed for an additional cost our electricians will upgrade the new panel cabinets alongside new breakers and overheads by following all the NEC codebook's electrical codes and requirements.
