Solar
Johnson Solar is a veteran-owned solar and electrical contractor based in El Cajon and serving San Diego County and surrounding Southern California communities. The company designs, installs, and services residential and commercial photovoltaic systems and offers battery storage, main-panel upgrades, EV charging, roof coordination, solar plans and permit packages, and project consulting. Its owner-led model emphasizes direct technical involvement, streamlined installation, and lower overhead compared with larger sales organizations. Johnson Solar also works with different roof types and ground- or structure-mounted configurations, giving customers options when a conventional south-facing rooftop array is not practical. A complete proposal should identify panel and inverter models, battery manufacturer and usable capacity, system size, projected annual production, monitoring, electrical-panel requirements, roof or structural scope, workmanship and equipment warranties, permitting, inspections, and SDG&E interconnection. Battery customers should ask which circuits will remain powered during outages and how the system will be programmed for time-of-use rates. Commercial clients should review service capacity, engineering, construction scheduling, and commissioning. Homeowners should verify which roofing work is performed directly versus coordinated with another contractor. Financing should be compared using total project cost and long-term payments rather than monthly payment alone.
