This presentation contains forward-looking statements that involve risks and uncertainties, including
statements regarding SolarCity’s customer and market growth opportunities, including the markets for
energy storage and related services; our estimated nominal contracted payments remaining; and
assumptions relating to the foregoing. Forward-looking statements should not be read as a guarantee
of future performance or results, and will not necessarily be accurate indications of the times at, or by,
which such performance or results will be achieved, if at all. Forward-looking statements are subject to
risks and uncertainties that could cause actual performance or results to differ materially from those
expressed in or suggested by the forward-looking statements. Additional key risks and uncertainties
include the availability of a sufficient, timely, and cost-effective supply of storage system components,
the success of our product development efforts and customer preferences, risks that consumers who
have executed energy contracts included in reported nominal contracted payments remaining and
backlog may seek to cancel those contracts, changes in strategic planning decisions by management
or reallocation of internal resources, and general market, political, economic and business conditions.
You should read the section entitled “Risk Factors” in our most recent Quarterly Report on Form 10-Q,
which has been filed with the Securities and Exchange Commission, which identify certain of these
and additional risks and uncertainties. We do not undertake any obligation to publicly update or revise
any forward-looking statement, whether as a result of new information, future developments or
otherwise, except as otherwise required by law.

Our approach to solar is being applied to storage
Our solar products have resulted in
$7.7B contracted customer payments
with a 120% annual growth rate since January, 2012
We lower customers energy bills by providing
solar energy with no upfront cost
Clean, More Affordable Energy

• Solar production and battery discharge reduce peak loads together
• Peak load periods occur in the summer from noon to 7pm
• Solar shaves the majority of the peak firmed up by the battery
• Solar storage systems are eligible for the investment tax credit
• Solar storage systems cost less to install than standalone battery systems as there
are common components (e.g. a common hybrid inverter)
• Single sales cycle for solar and storage with a greater combined value proposition
• 10x growth in battery sales and a 50% cost reduction since last year and we expect
growth and cost reduction to continue
With storage and solar the sum is greater
than its parts

Residential Cleaner more affordable backup power
Remote communities and the
developing world
Microgrids protect against outages and
provide more affordable power
Utilities Capacity and power quality services

7. SolarCity Confidential Slide 7
For commercial customers demand charges are a
significant portion of their electric bill

8. SolarCity Confidential Slide 8
Customer pays a lower rate for their demand
charges without any upfront investment
• Customer demand charges can be
as high as $20/kW/month
• Immediate savings with no capital
expense
• Learning algorithms determine the
optimal time to discharge the
batteries
• Also provides backup power
• Customers include multiple large
businesses like Walmart, BJs as
well as utilities and school districts

9. SolarCity Confidential Slide 9
Cheaper, cleaner residential backup
• 7kW of power and about
35kWh* off-grid energy (2x
average household power
needs)
• Can provide off-grid power
indefinitely without refueling
needs
• Fully installed for $4k
(significantly less than a
traditional backup generator)
• Ready for utility operation with
ancillary revenue potential
* 35kWh available on the first day assuming a 6kW solar system on a partly cloudy day

10. SolarCity Confidential Slide 10
• Massive costs are currently incurred in providing capacity and power quality in the
distribution system
• Representative example taken from a utility filing “Replace 9.2MVA transformer with
30MVA transformer to address 0.2MW deficiency at a cost of $4.35 Million”
• Solar and battery system can provide this capacity at a fraction of the cost
• Current opportunities are based on utility RFPs
• Market reform in New York, California, and Hawaii is attempting to modernize the
regulatory model so that utilities can more easily procure services from distributed,
behind the meter, batteries, smart solar inverters, and other distributed resources
Utility Opportunities

Microgrids can power remote communities and
add resiliency to existing grid connected locations
We offer the first available microgrid with no upfront costs
and pay-as-you-go financing, as well as a purchase option.
