Full-service solar and battery storage installation defines San Diego Solar MSR's scope at the 3653 La Cresta Dr address, with the operation managing initial consultation, system design, permit coordination, and final installation in-house. Roof preparation and underlayment integrity get verified before any rail mounting begins, often in coordination with roofers like Five Star Roofer San Diego on installs that follow a re-roof. Service catalog includes residential and commercial PV, solar roof repair on existing arrays, and battery integration for whole-home backup under California's NEM 3.0 export rules. Heat-pump conversions tied to solar offset modeling sometimes run parallel with HVAC swaps coordinated by shops like Efficient HVAC Solutions when the load calculations need to reflect new electrification demand. The most demanding jobs in a full-service solar operation are battery-plus-PV retrofits on existing roofs that require main-service-panel upgrades, line-side taps for non-export configurations, and SDG&E PTO coordination across multiple inspection cycles.
