New Construction Solar
for San Diego Builders
California's Title 24 mandate puts solar on every new home. We make it the easiest part of your build — turnkey design, permitting, and 100% in-house installation, delivered on your schedule.
Why Every New San Diego Home Needs Solar
Since 2020, California's Title 24 energy code has required solar on virtually every new low-rise home in the state. For San Diego builders, a compliant PV system isn't optional — it's a condition of occupancy. The only question is whether solar makes your build smoother or slows it down.
We've turned mandate compliance into a non-event. Our team sizes each system to the home's energy model, prepares the Title 24 documentation, and installs on schedule — so solar never sits on the critical path to your certificate of occupancy.
Why San Diego Builders Choose Us
You don't need another subcontractor to manage. You need a licensed solar partner who delivers on schedule, every lot, and takes the mandate off your plate.
Title 24 Mandate Compliance, Handled
California’s solar mandate requires solar PV on virtually every new low-rise home. We size, document, and certify systems that pass Title 24 and CF-1R/CF-2R review the first time — so solar never holds up your certificate of occupancy.
One Company, One Point of Accountability
No coordinating a separate solar subcontractor against your GC and electrician. Our in-house design, engineering, and installation teams plug directly into your project so there’s a single number to call when the schedule moves.
We Build to Your Schedule
We’ve run San Diego construction timelines for 30 years. We stage design, permitting, and installation around your framing, roofing, and inspection milestones — not the other way around.
Per-Lot & Volume Pricing
Repeatable designs across a subdivision mean repeatable pricing. We offer per-lot and volume programs for production builders, with predictable costs you can underwrite into each home.
Permitting & SDG&E Interconnection at Scale
We’ve processed thousands of City of San Diego permits and SDG&E interconnection applications. We manage the paperwork across every lot so nothing stalls at final inspection or PTO.
Production, Custom & Multifamily
From a single custom estate to a full tract or multifamily development, our crews handle tile, metal, flat, and composition roofs and integrate battery storage where the build calls for it.

Permitting & Schedule Integration
We pull City permits and file SDG&E interconnection for each lot, then slot installation into your construction calendar around roofing and rough-in milestones.
In-House Installation
Our own crews — never subcontractors — install each system to spec, on schedule, with the consistency a production build demands across every home.
Inspection, Interconnection & Handoff

Common Questions About New Construction Solar in San Diego
Yes. Since 2020, the California Energy Code (Title 24) has required solar photovoltaic systems on virtually all new low-rise residential construction, including single-family homes and many multifamily buildings. The 2022 update further added battery-readiness and electrification provisions. For San Diego builders, this means a compliant solar system is effectively mandatory on every new home — San Diego Solar designs and documents systems that satisfy the requirement.
Title 24, Part 6 is California’s Building Energy Efficiency Standards. For new homes it sets a minimum solar PV system size based on the home’s conditioned floor area and climate zone, documented through CF-1R (compliance) and CF-2R (installation) forms. We handle the solar sizing and documentation so your project passes plan check and final inspection without delays.
