Semper Solaris - El Cajon CA
Semper Solaris
Solar
Semper Solaris is a veteran-owned San Diego County home-services contractor headquartered in El Cajon and offering residential solar, battery storage, roofing, HVAC, windows and doors, and related energy upgrades. The company has a large regional installation operation and can coordinate several major home projects through one provider. Its solar offering includes customized photovoltaic systems and battery-storage options, while its roofing and HVAC divisions can address roof condition and future electricity demand before the final solar design is selected. This integrated approach is useful for homeowners planning a reroof, heat-pump or air-conditioning replacement, battery, and solar at the same time. Customers should request separate line-item pricing for solar, batteries, roofing, HVAC, windows, and electrical upgrades rather than evaluating only a combined monthly payment. The solar proposal should identify panel and inverter equipment, array capacity, expected annual production, monitoring, battery usable capacity, backup circuits, roof attachments, warranties, permitting, inspections, and SDG&E interconnection. Financing customers should compare the cash price with total financed cost and understand lender fees and contract terms. Homeowners should also clarify which regional crews handle installation and service and how warranty repairs are scheduled if equipment fails years after activation.
