A residential solar project usually moves through home qualification, site review, technical design, permitting, installation, local inspection, utility interconnection and permission to operate. Physical installation may be relatively short, but approvals before and after it can take longer.
Design follows property review
The project team uses roof, electrical, utility and energy information to create a system design. Changes in roof condition, electrical equipment, setbacks or utility requirements can affect the original proposal.
Permits and utility review run on outside timelines
Local authorities and utilities control important approvals. Timelines vary by jurisdiction, workload, application completeness and whether corrections are required. A responsible estimate includes uncertainty.
Installation is not activation
After installation, inspections and utility steps may remain. Homeowners should not switch on or modify the system until authorized. The project is complete when required approvals, monitoring and homeowner handoff are finished.
