5. Incentives 4 step declining incentive structure Single Family: Based on SRCC OG-300 savings Multifamily/Commercial (SRCC OG-100) Small systems: based on a TRNSYS estimator Large systems: based on 12 months of metered performance data Different incentive amounts for natural gas vs. electric displacing systems

14. Residential Statistics by System Type

15. Statistics Summary Most common system in San Diego: Indirect - Glycol Average price range: $5,500 - $7,000 Average performance range: 2100-3200 kWh 97-141 therms Each system has unique characteristics, with differing pros and cons

16. Energy Savings=Financial Savings Displacing Electricity: Average home uses 4,000 kWh annually for water heating (purchased from utility) Average SWH system saves 2,820 kWh 4,000-2,820= 1180 kWh purchased from utility 70% savings= 70% reduction on water heating costs

17. Energy Savings=Financial Savings Displacing Gas: Average home uses 200 thermsannually for water heating (purchased from utility) Average SWH system saves 123 therms 200-123= 77 thermspurchased from utility 60% savings= 60% reduction on water heating costs

18. Testimonials from your neighbors We installed a solar hot water heater and our December natural gas savings was 54% -Mark S., San Diego We just received our first natural gas bill after installing a solar water heater and we have reduced natural gas usage by 83% over last year –Glen B., San Diego
