Why San Diego Professionals Choose Solar Water Heaters
With over 260 sunny days annually, San Diego is ideal for solar thermal technology. A well-sized solar water heater can meet up to 80% of a household's hot-water needs, reduce utility bills, and increase property value. In 2025, installation costs range from $8,800 before incentives, with potential reductions to $5,600 after applying the 30% Federal ITC and local rebates.
Understanding Solar Water Heater Systems
Solar water heaters use roof-mounted collectors to capture sunlight, transferring heat to a storage tank. Most systems in San Diego are active, indirect designs with freeze-protected heat-transfer fluid. Key components include the collector array and a heat exchanger-equipped storage tank.
Key Technical Terms
- Collector Efficiency – ratio of solar energy converted to usable heat
- Solar Fraction – percentage of total hot-water load met by the system
- OG-100/OG-300 – SRCC certifications required by California code
Cost Breakdown for an 80-Gallon System
- Collectors: 40% of budget (2–3 high-efficiency flat plates)
- Storage Tank & Heat Exchanger: 20%
- Pumps, Controllers, Piping: 15%
- Roof Mount & Flashing: 10%
- Permits, Labor, Inspection: 15%
