Residential solar installation follows a proven, efficient process that empowers homeowners to achieve energy independence and substantial savings. Aztec Electric Renewables, a trusted local expert in electrical and solar services, streamlines every step with their licensed, NABCEP-certified team for seamless results.
Initial Consultation and Site Assessment
Aztec begins with a complimentary consultation, analyzing your utility bills to pinpoint energy usage patterns and savings potential. Their technicians perform a thorough site visit, evaluating roof pitch, orientation (ideally south-facing), shading from trees or neighboring structures, and structural load capacity using advanced tools like drone surveys. This ensures your system maximizes Corona’s 280+ sunny days annually.
Expect a detailed proposal within 48 hours, projecting 80-100% bill offset, 5-7 year payback, and 25-year performance guarantees on premium panels from brands like REC or Qcells.
Custom System Design and Engineering
Aztec’s engineers craft a tailored blueprint using PVsyst software, selecting optimal components: high-efficiency monocrystalline panels (380-450W), microinverters (e.g., Enphase IQ8) for shade tolerance, and racking for tile or shingle roofs. Designs incorporate electrical panel upgrades, EV charger readiness, and optional Tesla Powerwall integration for blackout protection.
Company data shows their average residential system: 6-8kW, generating 9,000-12,000 kWh yearly, slashing Southern California Edison bills by $2,500+ annually.
Permitting and Utility Approvals
Aztec manages all paperwork, submitting plans to the City of Corona and SCE for building permits, fire setbacks (18 inches between rows), and NEM 3.0 interconnection agreements—typically approved in 4-6 weeks. Their 15+ years of local experience accelerates this, avoiding common delays.
Over 500 successful installs prove their expertise in navigating California’s Title 24 energy codes and AHJ inspections.
Equipment Sourcing and Preparation
Premium NABCEP-sourced gear arrives pre-staged: panels with 25-year warranties, 12-year inverters, and UL-listed conduit. Aztec quality-checks everything on-site, ensuring compatibility for hybrid AC/DC setups. Their bulk partnerships keep costs 10-15% below market averages.
Hands-On Installation Phase
Professional crews (insured, uniformed) complete the physical work in 1-3 days. Day 1: Roof flashing, racking installation with torque-certified bolts. Day 2: Panel mounting, series wiring via MC4 connectors, inverter placement. Safety first—OSHA harnesses, lockout/tagout, and rapid shutdown compliance.
Minimal disruption: Work 8am-5pm, daily cleanup, no interior mess.
Electrical Hookup and System Testing
Wiring routes DC from arrays to inverters, converting to AC for your panel via a 200A upgrade if needed. Rigorous testing follows: open-circuit voltage, ground continuity, insulation resistance via megger, and string balance. Thermal scans detect hotspots early.bostonsolar+1
Aztec’s dual electrical-solar licensing ensures NEC 2023 compliance.
Official Inspections
Pasadena-area inspectors (serving Corona) verify structural, electrical, and fire safety on first pass 98% of the time. Aztec coordinates scheduling for speed.
Grid Interconnection and Activation
SCE installs bidirectional net metering; PTO issues in 7-10 days. System goes live—app shows instant production, often 30-50kWh Day 1.energysage+1
Monitoring and Owner Training
Aztec sets up Enlighten or SolarEdge apps for real-time kWh tracking, alerts, and consumption graphs. Personalized walkthrough covers optimization tips like time-of-use shifting.
Ongoing Maintenance and Support
Annual cleanings (boosting output 5-10%), drone inspections, and 24/7 hotline. 25-year Aztec workmanship warranty backs equipment. Company stats: 99% uptime across 1,200+ systems.
