Go Solar California!• Million Solar Roofs Bill (SB1)

• Signed by Gov. Schwarzenegger on September 21, 2006

• Ended solar incentives through the ERP and SGIP

• Launched the California Solar Initiative (CSI) and New Solar Homes Partnership (NSHP).

California Solar Initiative (CSI):

Overview of Residential Solar Market

77

California Solar Initiative (CSI)• As part of the “Go Solar California”

campaign, the California Solar Initiative (CSI) was instituted to help facilitate the installation of 1,750 MW statewide and create a sustainable solar industry

• Of the 1,750 MW, CCSE is due to install 180 MW by end of 2016

• 59 of which will come from the residential sector (roughly 15,000 average size systems)

88

CSI Rebates• Rebates are offered on a declining

scale• Current CSI Incentive (upfront):

$1.55/Watt• Next rebate amount is $1.10/Watt

99

CSI Rebates

• Offsets roughly 15% to 20% of the total installed costs

• Rebates will decline as more solar gets installed

1010

1111

Other Incentives• 30% Federal Tax Credit – can be

taken after CSI Incentive is deducted

1212

CSI Application Process• Residential and Small Non-

Residential projects (< 10 kW) • Two Step Application Process

• Non-Residential projects (> 10 kW) • Three Step Application Process

Current Cost Per Watt by System Size: Residential

• PV costs range from $8.50 to $11.50 per watt fully installed… before taking rebates or tax credits. The average cost of all residential systems to date is $9.28 per watt.

Current $/Watt by Residential System Size in California

Systems 1 kW – 5 kW = $9.71/WattSystems 5 kW – 10 kW = $9.12/WattSystems 10 kW and up = $9.03/Watt

Average Residential System Size = $9.28/Watt

The Future of CSI: Paperless Applications

5050

Why Paperless?Reduce Carbon Footprint of the Program• PDF submittal means less documents to be

printed• Lowers fuel consumption by eliminating

transportation of documents from one location to another

More Efficient Application = Reduced Cost

• Single location for most current forms• Eliminate postage cost and other Admin cost for

preparing mail• No more duplicate data entry from Excel Forms

5151

Future Paperless Submittal Process

APPLICANT

PA Begins Review Process

1. Fill out CSI Forms using PowerClerk

2. Prepare Supporting Documentation

3. Email or attach documentation to PC

5252

PowerClerk Data Upload FeaturePurpose of the feature

• Allows external software programs to upload application data to populate CSI Reservation Request Forms

• Streamlines process & eliminates duplicate entry of data by Applicant and CSI Administrators

**Recommended for large installers whose custom tools auto-populate excel rebate and interconnection paperwork

Solar Water Heating Incentive Programs

Outline• What is Solar Water Heating?• Solar Water Heating Pilot

Program• Eligibility• Incentives

• CSI-Thermal Program• Expected timeline• Proposed elements

• Economics of Solar Water Heating

5656

What is Solar Water Heating?• Solar Assist or Solar Pre-heat• Always keep the existing heater

as backup to solar• Great way to conserve energy,

reduce your utility bill, increase the value of your home, and reduce Global Warming!

5757

How does it work? First, understand conventional

water heaters:• Conventional water heaters maintain hot

water in the storage tank around 120-140 degrees F.

• When the water temperature drops below that, your electricity or natural gas will kick on to heat the water to the appropriate temperature.

• This happens while you are at work all day, even though there is no demand for hot water

5858

58

Basic SWH Design

1. Sun heats water or a heat transfer fluid in a solar collector on the roof

2. Solar heated water is stored in solar tank

3. Solar heated water circulates between solar tank and back up water heater

4. Back up water heater boosts the temperature of the water, if needed

5. Use solar heated water !

What is the Solar Water Heating Pilot Program?

• The Solar Water Heating Pilot Program, part of the larger California Solar Initiative, was designed to gather information on the market, technologies and financials of SWH in order to expand to a statewide program.• Total SWHPP budget is $1.5 million for

incentives• Program rolled out on July 2, 2007 and will

run through Dec. 31, 2009• CSI-Thermal Program was proposed July 15,

2009- statewide incentive program

6161

SWH Pilot Program - Eligibility• Eligible:

• SDG&E electric customers only, nowhere else in the state

• Natural Gas, Electric, and Propane users are all eligible

• New construction and retrofit projects • Not Eligible:

• Pools and Spas are not eligible• Other thermal technologies, such as space

heating and cooling, are not eligible• Replacement of single components is not

eligible

6262

SWH Pilot Program-Requirements

• Eligible Contractor• SRCC Certified System• Two step application process• City or County Permit• SWHPP Inspection

6363

Incentives - Residential• Maximum Incentive: $1,500

• Solar Orientation Factor (SOF) – 0.9 to 1.0 based on tilt and orientation

• SRCC Annual Savings of the OG-300 System (System Rating)

• Incentive Calculation:• Natural Gas Offset: Maximum Incentive x (SOF) x

(System Rating/150 therms)= Incentive Amount• Electric Offset: Maximum Incentive x (SOF) x

(System Rating/3000 kWh)= Incentive Amount• Example:

• Natural Gas: $1,500 x 1.0 x (125/150)= $1,250• Electric: $1,500 x 1.0 x (2500/3000)= $1,250

6464

Incentives – Commercial• Maximum Incentive: $75,000

• Solar Orientation Factor (SOF) – 0.9 to 1.0 based on tilt and orientation

• SRCC Annual Savings of the OG-100 Collector- thousands of Btu/day

• Incentive Calculation: • Closed Loop: $20 x (SOF) x (System Rating) = Incentive

Amount• Open Loop : $15 x (SOF) x (System Rating) = Incentive

Amount• Example:

• Closed Loop: $20 x 1.0 x 35 = $700 per collector• Open Loop : $15 x 1.0 x 35 = $525 per collector

6565

Additional Incentives• Federal Tax Credit – 30% of cost

(post-incentive) (No cap)

• Increased property value but exempt from increase property tax

• Protection against future rate increases

6666

Economics of SWH• “One of the most cost-effective ways

to include renewable technologies into a building is by incorporating solar hot water.”

–U.S. Department of Energy website
