• $2.1 billion program for 10 years
(2007-2016)
• Financed through rate-payers
• 10% of funds set aside for low-
income ratepayers
Solar incentive program in California for IOU customers: Pacific Gas and Electric Southern California Edison, and San Diego Gas & Electric (administered by CCSE)

MASH Program - Goals
1. Stimulate adoption of solar power in the affordable housing sector
2. Improve energy utilization and overall quality of affordable housing through application of solar and energy efficiency technologies
3. Decrease electricity use and costs without increasing monthly household expenses for affordable housing building occupants
4. Increase awareness and appreciation of the benefits of solar among affordable housing occupants and developers

MASH Program- Structure
Different incentive for:
• common area meters $3.30/Watt-AC• tenant meters $4.00/Watt-AC
Program required at least 20% of incentive dollars to go tooffsetting tenant load
Solar Costs about $6-8/Watt-AC

Virtual Net Metering
MASH Program- Structure
14www.energycenter.org
What is Net Metering?
• Net metering is a method of “banking” excess electricity credits.
15www.energycenter.org
How does Net Metering work?
- Producing more than consuming(spinning the meter backwards)
- Consuming more than producing(spinning the meter forward)
16www.energycenter.org
Virtual Net Metering
Simply a way to distribute
solar generation credits from
a single PV system
mathematically (virtually)
across multiple meters

MASH Program - Challenges
• Capital constraints
• Regulated rents limit cash flows to property owners-
utility allowance adjustments difficult for retrofits

MASH Program - Challenges
• Capital constraints
• Regulated rents limit cash flows to property owners-
utility allowance adjustments difficult for retrofits• High learning curve for affordable housing property
owners and lenders
27www.energycenter.org
MASH Program - Strategies
• Large incentives helped bring solar providers to the
sector

MASH Program - Strategies
• Large incentives helped bring solar providers to the
sector
• Marketing, Outreach, and Education
• Educated contractors and used their marketing
channels
• Reached out to affordable housing sector through
conferences/workshops/trade association meetings
• Gave property owners and contractors tools to educate
lenders/ financing partners

MASH Program - Strategies
• Large incentives helped bring solar providers to the
sector
• Marketing, Outreach, and Education
• Educated contractors and used their marketing
channels
• Reached out to affordable housing sector at
conferences/workshops/trade association meetings
• Gave property owners and contractors tools to educate
lenders/ financing partners
• Program progress has relied on a relatively small
core of motivated property owners/managers and
solar contractors (early adopters)
32www.energycenter.org
MASH Program – Lessons Learned
• Marketing, Outreach, & Education
• Leverage contractors’ marketing channels for M&O
• Flatten learning curve for property owners and lenders
through targeted educational efforts
• Don’t “over-incentivize” PV dedicated to common area
meters
• Meaningful energy efficiency requirements can increase
participant/utility/societal benefits
33www.energycenter.org
Considerations for DC
• Characterize your affordable housing building stock and market as it relates to solar:• Electricity usage and costs• Roof to living space ratio• Metering- Master metered or individual tenant meters
• Consider a variety of models, community solar, on-site solar
• Foster cross program collaboration with energy efficiency efforts
• Evaluate other technologies- SWH, Fuel cells
