Forward-Looking
Statements
This presentation contains forward-looking statements that involve
risks and uncertainties, including statements regarding SolarCity’s
forecast for manufacturing cell efficiencies; expected reductions in
manufacturing costs; potential financial and other benefits of the
acquisition; and assumptions related 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 level of demand for our solar energy systems, the
availability of a sufficient, timely, and cost-effective supply of solar
panels and balance of system components, the effects of future tariffs
and other trade barriers, changes in federal tax treatment, the effect
of electric utility industry regulations, net metering and related policies,
the availability and amount of rebates, tax credits and other financial
incentives, the availability and amount of financing from fund investors,
the retail price of utility-generated electricity or the availability of
alternative energy sources, risks associated with SolarCity’s rapid
growth, risks that consumers who have executed energy contracts
included in reported nominal contracted payments remaining and
backlog may seek to cancel those contracts, assumptions as to
retained value under energy contracts and contract renewal rates and
terms, including applicable net present values, performance-based
incentives, and other rebates, credits and expenses, SolarCity’s limited
operating history, particularly as a new public company, 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 identifies 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.

High Efficiency Solar Module
Technology and Manufacturing
••Technology and integrated manufacturing capability to create industry-leading cost structure
that aims to make solar competitive with grid costs
••Triex tunneling junction technology produces high efficiency at a low cost due to a simple,
proprietary manufacturing process
••Manufacturing capacity will create the most vertically integrated solar company – from modules
and mounting hardware to finance, installation, and energy sales
••Transaction value of $200M with up to $150M in earn-outs based on volume and cost targets

Triex Tunneling Junction:
High Efficiency at Low Cost
Greater Revenue at Lower Cost per Watt
Tunneling layer =
Higher Efficiency
— Lower system costs
— Less solar panels required for the same system size
24% target cell efficiency
Crystalline-amorphous hybrid cell =
Better Energy Harvest
— More revenue per watt
— Lower temperature coefficient
-0.22%/C cell
-0.27%/C module
Simple process =
Low Manufacturing Costs
— Lower panel costs
— Simple manufacturing process
— Copper electrode metallization

Higher Efficiency Reduces Space,
Materials, and Cost
Cell Efficiency of 24% Reduces Number of Panels per Equivalent Installation by 25%
Silevo’s high efficiency enables 340-W modules with the same form factor as standard
250-W modules today
24 panels
× 250 Watts per panel
= 6 kW System Size
18 panels
× 340 Watts per panel
= 6kW System Size
Higher efficiency requires
fewer panels per system size
and reduces cost/watt of:
•• Installation/Labor
•• Balance of System
•• Mounting Hardware
