Overview

    Sunrun's mission is to provide our customers with clean, affordable solar
energy and storage, and a best-in-class customer experience. In 2007, we
pioneered the residential solar service model, creating a low-cost solution for
customers seeking to lower their energy bills. By removing the high initial cost
and complexity of cash system sales that used to define the residential solar
industry, we have fostered the industry's rapid growth and exposed an enormous
market opportunity. Our relentless drive to increase the accessibility of solar
energy is fueled by our enduring vision: to create a planet run by the sun.

    We provide clean, solar energy typically at savings compared to traditional
utility energy. Our primary customers are residential homeowners. We also offer
battery storage along with solar energy systems to our customers in select
markets and sell our services to certain commercial developers through our
multi-family and new homes offerings. After inventing the residential solar
service model and recognizing its enormous market potential, we have built the
infrastructure and capabilities necessary to rapidly acquire and serve customers
in a low-cost and scalable manner. Today, our scalable operating platform
provides us with a number of unique advantages. First, we are able to drive
distribution by marketing our solar service offerings through multiple channels,
including our diverse partner network and direct-to-consumer operations. This
multi-channel model supports broad sales and installation capabilities, which
together allow us to achieve capital-efficient growth. Second, we are able to
provide differentiated solutions to our customers that, combined with a great
customer experience, we believe will drive meaningful margin advantages for us
over the long term as we strive to create the industry's most valuable and
satisfied customer base.

    Our core solar service offerings are provided through our lease and power
purchase agreements, which we refer to as our "Customer Agreements" and which
provide customers with simple, predictable pricing for solar energy that is
insulated from rising retail electricity prices. While customers have the option
to purchase a solar energy system outright from us, most of our customers choose
to buy solar as a service from us through our Customer Agreements without the
significant upfront investment of purchasing a solar energy system. With our
solar service offerings, we install solar energy systems on our customers' homes
and provide them the solar power produced by those systems for typically a
20-year initial term. In certain markets, we offer a 25-year initial term
service offering. In addition, we monitor, maintain and insure the system during
the term of the contract. In exchange, we receive predictable cash flows from
high credit quality customers and qualify for tax and other benefits. We finance
portions of these tax benefits and cash flows through tax equity, non-recourse
debt and project equity structures in order to fund our upfront costs, overhead
and growth investments. We develop valuable customer relationships that can
extend beyond this initial contract term and provide us an opportunity to offer
                                       32
--------------------------------------------------------------------------------

additional services in the future, such as our home battery storage service.
Since our founding, we have continued to invest in a platform of services and
tools to enable large scale operations for us and our partner network, and these
partners include solar integrators, sales partners, installation partners and
other strategic partners. The platform includes processes and software, as well
as fulfillment and acquisition of marketing leads. We believe our platform
empowers new market entrants and smaller industry participants to profitably
serve our large and underpenetrated market without making the significant
investments in technology and infrastructure required to compete effectively
against established industry players. Our platform provides the support for our
multi-channel model, which drives broad customer reach and capital-efficient
growth.
    Delivering a differentiated customer experience is core to our strategy. We
emphasize a customized solution, including a design specific to each customer's
home and pricing configurations that typically drive both customer savings and
value to us. We believe that our passion for engaging our customers, developing
a trusted brand, and providing a customized solar service offering resonates
with our customers who are accustomed to a traditional residential power market
that is often overpriced and lacking in customer choice.
We have experienced substantial growth in our business and operations since our
inception in 2007. As of March 31, 2020, we operated the second largest fleet of
residential solar energy systems in the United States. We have an aggregate
of 2,085 Megawatts Deployed as of March 31, 2020, and our Gross Earning Assets
as of March 31, 2020 were approximately $3.9 billion. Please see the section
entitled "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Key Operating Metrics" for more details on how we
calculate Megawatts Deployed and Gross Earning Assets.
    We also have a long track record of attracting low-cost capital from diverse
sources, including tax equity and debt investors. Since inception we have raised
tax equity investment funds to finance the installation of solar energy systems.
Recent Impacts of COVID-19 on Our Business
The COVID-19 pandemic and the resulting impact on the U.S. economy have
accelerated many of our operational initiatives to deliver best-in-class
customer value and to reduce costs. We have invested in technology to streamline
our installation processes, including online permitting and interconnection in
many locations, as well as employing extensive use of drone technology to
complete rooftop surveys. While we continue to install solar systems in most
markets, we are monitoring this fluid situation and will follow official
regulations to protect our employees and customers.
Following the first shelter-in-place orders in California, we enabled our entire
salesforce to complete sales consultations in a virtual setting. Despite the
fact that we have paused sourcing leads through certain channels, we have seen
more leads through our digital channels at similar or more attractive customer
acquisition costs. We believe this transition towards a digital model will
position us well to realize sustaining reductions in customer acquisition costs.
A significant portion of our business model is directly variable with
deployments currently sold and built by our channel partners. In the remainder
of our business, we have already taken actions to significantly lower our
expenses, primarily from various labor-related cost actions, which we believe
strike an appropriate balance that considers the welfare of our employees,
protecting the business against possible downside scenarios, and preserving our
ability to grow quickly as the situation stabilizes.
The ultimate impact of the COVID-19 pandemic is highly uncertain and subject to
change, and we do not yet know the full extent of potential delays or impacts on
our business, operations or the global economy as a whole. We will continue to
monitor developments affecting our workforce, our customers, and our business
operations generally and will take additional actions that we determine are
necessary in order to mitigate these impacts.

Investment Funds
Our Customer Agreements provide for recurring customer payments, typically over
20 or 25 years, and the related solar energy systems are generally eligible for
Commercial ITCs, accelerated tax depreciation and other government or utility
incentives. Our financing strategy is to monetize these benefits at a low
weighted average cost
                                       33
--------------------------------------------------------------------------------

of capital. This low cost of capital enables us to offer attractive pricing to
our customers for the energy generated by the solar energy system on their
homes. Historically, we have monetized a portion of the value created by our
Customer Agreements and the related solar energy systems through investment
funds. These assets are attractive to fund investors due to the long-term,
recurring nature of the cash flows generated by our Customer Agreements, the
high credit scores of our customers, the fact that energy is a non-discretionary
good and our low loss rates. In addition, fund investors can receive attractive
after-tax returns from our investment funds due to their ability to utilize
Commercial ITCs, accelerated depreciation and certain government or utility
incentives associated with the funds' ownership of solar energy systems.
As of March 31, 2020, we had 34 active investment funds, which are described
below. We have established different types of investment funds to implement our
asset monetization strategy. Depending on the nature of the investment fund,
cash may be contributed to the investment fund by the investor upfront or in
stages based on milestones associated with the design, construction or
interconnection status of the solar energy systems. The cash contributed by the
fund investor is used by the investment fund to purchase solar energy systems.
The investment funds either own or enter into a master lease with a Sunrun
subsidiary for the solar energy systems, Customer Agreements and associated
incentives. We receive on-going cash distributions from the investment funds
representing a portion of the monthly customer payments received. We use the
upfront cash, as well as on-going distributions, to cover our costs associated
with designing, purchasing and installing the solar energy systems. In addition,
we also use debt, equity and other financing strategies to fund our operations.
The allocation of the economic benefits between us and the fund investor and the
corresponding accounting treatment varies depending on the structure of the
investment fund.
We currently utilize three legal structures in our investment funds, which we
refer to as: (i) pass-through financing obligations, (ii) partnership flips and
(iii) joint venture ("JV") inverted leases. We reflect pass-through financing
obligations on our consolidated balance sheet as a pass-through financing
obligation. We record the investor's interest in partnership flips or JV
inverted leases (which we define collectively as "consolidated joint ventures")
as noncontrolling interests or redeemable noncontrolling interests. These
consolidated joint ventures are usually redeemable at our option and, in certain
cases, at the investor's option. If redemption is at our option or the
consolidated joint ventures are not redeemable, we record the investor's
interest as a noncontrolling interest and account for the interest using the
hypothetical liquidation at book value ("HLBV") method. If the investor has the
option to put their interest to us, we record the investor's interest as a
redeemable noncontrolling interest at the greater of the HLBV and the redemption
value.

millions):

For further information regarding our investment funds, including the associated
risks, see Part II, Item 1A. Risk Factors- "Our ability to provide our solar
service offerings to customers on an economically viable basis depends in part
on our ability to finance these systems with fund investors who seek particular
tax and other benefits", as well as Note 10, Pass-through Financing Obligations,
Note 11, VIE Arrangements and Note 12, Redeemable Noncontrolling Interests and

Quarterly Report on Form 10-Q.

Key Operating Metrics
We regularly review a number of metrics, including the following key operating
metrics, to evaluate our business, measure our performance, identify trends
affecting our business, formulate financial projections and make strategic
decisions. Some of our key operating metrics are estimates that are based on our
management's beliefs and assumptions and on information currently available to
management. Although we believe that we have a reasonable basis for each of
these estimates, we caution you that these estimates are based on a combination
of assumptions that may prove to be inaccurate over time. Any inaccuracies could
be material to our actual results when compared to our calculations. Please see
the section titled "Risk Factors" in this Quarterly Report on Form 10-Q for more
information. Furthermore, other companies may calculate these metrics
differently than we do now or in the future, which would reduce their usefulness
as a comparative measure.

•Megawatts Deployed represents the aggregate megawatt production capacity of our
solar energy systems, whether sold directly to customers or subject to executed
Customer Agreements (i) for which we have confirmation that the systems are
installed on the roof, subject to final inspection; (ii) in the case of certain
system installations by our partners, for which we have accrued at least 80% of
the expected project cost, or (iii) for multi-family and any other systems that
have reached NTP, measured on the percentage of the project that has been
completed based on expected project cost.

•Gross Earning Assets represents the net cash flows (discounted at 6%) we expect
to receive during the initial term of our Customer Agreements (typically 20 or
25 years) for systems that have been deployed as of the measurement date, plus a
discounted estimate of the value of the Customer Agreement renewal term or solar
energy system purchase at the end of the initial term. Consistent with industry
standards, we use a discount rate of 6%. We consider a discount rate of 6% to be
appropriate and consistent with recent market transactions that demonstrate that
a portfolio of residential solar customer contracts is an asset class that can
be securitized successfully on a long-term basis, with a coupon of less than 5%.
We calculate the Gross Earning Assets value of the purchase or renewal amount at
the expiration of the initial contract term assuming either a system purchase or
a five year renewal (for our 25-year Customer Agreements) or a 10-year renewal
(for our 20-year Customer Agreements), in each case forecasting only a 30-year
customer relationship (although the customer may renew for additional years, or
thereafter purchase the system), at a contract rate equal to 90% of the
customer's contractual rate in effect at the end of the initial contract term.
After the initial (generally 20 or 25 year) contract term, our Customer
Agreements typically automatically renew on an annual basis and the rate is
initially set at up to a 10% discount to then-prevailing power prices.

Gross Earning Assets is calculated net of estimated cash distributions to
investors in consolidated joint ventures and estimated operating, maintenance
and administrative expenses for systems deployed as of the measurement date. In
calculating Gross Earning Assets, we deduct estimated cash distributions to our
project equity financing providers. In calculating Gross Earning Assets, we do
not deduct customer payments we are obligated to pass through to investors in
pass-through financing obligations as these amounts are reflected on our balance
sheet as long-term and short-term pass-through financing obligations, similar to
the way that debt obligations are presented. In determining our finance
strategy, we use pass-through financing obligations and long-term debt in an
equivalent fashion as the schedule of payments of distributions to pass-through
financing obligation investors is more similar to the payment of interest to
lenders than the internal rates of return (IRRs) paid to investors in other tax
equity structures.

•Gross Earning Assets Under Energy Contract represents the net cash flows during
the initial term of our Customer Agreements (less substantially all value from
SRECs prior to July 1, 2015), for systems deployed as of the measurement date.

•Gross Earning Assets Value of Purchase or Renewal is the forecasted net present
value we would receive upon or following the expiration of the initial Customer
Agreement term (either
                                       35
--------------------------------------------------------------------------------

in the form of cash payments during any applicable renewal period or a system purchase at the end of the initial term), for systems deployed as of the measurement date.



Gross Earning Assets is forecasted as of a specific date. It is forward-looking,
and we use judgment in developing the assumptions used to calculate it. Factors
that could impact Gross Earning Assets include, but are not limited to, customer
payment defaults, or declines in utility rates or early termination of a
contract in certain circumstances, including prior to installation.

Critical Accounting Policies and Estimates



    Our discussion and analysis of our financial condition and results of
operations are based upon our financial statements, which have been prepared in
accordance with generally accepted accounting principles in the United States
("GAAP"). GAAP requires us to make estimates and assumptions that affect the
reported amounts of assets, liabilities, revenue, expenses and related
disclosures. We base our estimates on historical experience and on various other
assumptions that we believe to be reasonable under the circumstances. In many
instances, we could have reasonably used different accounting estimates, and in
other instances, changes in the accounting estimates are reasonably likely to
occur from period-to-period. Actual results could differ significantly from our
estimates. Our future financial statements will be affected to the extent that
our actual results materially differ from these estimates. For further
information on all of our significant accounting policies, see Note 2, Summary
of Significant Accounting Policies, to our consolidated financial statements
included elsewhere in this Quarterly Report on Form 10-Q.

    We believe that policies associated with our principles of consolidation,
revenue recognition, impairment of long-lived assets, provision for income taxes
and calculation of noncontrolling interests and redeemable noncontrolling
interests have the greatest impact on our consolidated financial statements.
Therefore, we consider these to be our critical accounting policies and
estimates.

Customer Agreements and Incentives. The $15.7 million increase in revenue from
Customer Agreements was primarily due to both an increase in solar energy
systems under Customer Agreements being placed in service in the period from
April 1, 2019 through March 31, 2020, plus a full quarter of revenue recognized
in the first quarter of 2020 for systems placed in service in the first quarter
of 2019 versus only a partial quarter of such revenue related to the period in
which the assets were in service in 2019. Revenue from incentives consists of
sales of ITCs and SRECs, which decreased by $16.5 million during the three
months ended March 31, 2020, compared to the prior year. The decrease was due to
the sale of ITCs under a financing obligation fund opened in 2018, with PTO
activity in that fund primarily concluding during the second quarter of 2019.
There has been no such comparable fund opened in 2019 or 2020.
Solar Energy Systems and Product Sales. Revenue from solar energy systems sales
increased by $12.8 million compared to the prior year due to increased demand
through retail partners. Product sales increased by $4.1 million, primarily due
to an increase in the volume of wholesale products sold.

Cost of Customer Agreements and Incentives. The $8.8 million increase in Cost of
customer agreements and incentives was primarily due to the increase in solar
energy systems placed in service in the period from April 1, 2019 through
March 31, 2020, plus a full quarter of costs recognized in the first quarter of
2020 for systems placed in service in the first quarter of 2019 versus only a
partial quarter of such expenses related to the period in which the assets were
in service in 2019.

--------------------------------------------------------------------------------

The cost of Customer Agreements and incentives increased to 79% of revenue from
customer agreements and incentives during the three months ended March 31, 2020,
from 70% during the three months ended March 31, 2019 due to the $16.5 million
decrease in revenue from incentives, as discussed above. The cost of sales
related to incentives was minimal.
Cost of Solar Energy Systems and Product Sales. The $13.8 million increase in
Cost of solar energy systems and product sales was due to the corresponding net
increase in the solar energy systems and product sales discussed above.
Sales and Marketing Expense. The $14.3 million increase in Sales and marketing
expense was primarily attributable to an increase in headcount driving higher
employee compensation, as well as an increase in costs to acquire customers
through our retail channels and sales lead generating partners. Included in
sales and marketing expense is $3.4 million and $2.7 million of amortization of
costs to obtain Customer Agreements for the three months ended March 31, 2020
and 2019, respectively, as well as $1.0 million related to furlough benefits and
severance for the three months ended March 31, 2020.
Research and Development Expense. The $1.4 million decrease in Research and
development expense was primarily attributable to a slight decrease in headcount
resulting in lower employee compensation.
General and Administrative Expense. The $1.0 million decrease in General and
administrative expenses was primarily attributable to a decrease in consulting
and other professional fees.
During the three months ended March 31, 2020, we incurred $2.2 million of
furlough benefit and severance costs incurred in the following line items within
the consolidated statement of operations (in thousands):
Cost of customer agreements and incentives          $   807

Interest Expense, net. The increase in Interest expense, net of $8.6 million was
related to additional non-recourse and pass-through financing obligation debt
entered into subsequent to March 31, 2019. Included in net interest expense is
$6.1 million and $5.9 million of non-cash interest recognized under Customer
Agreements that have a significant financing component for the three months
ended March 31, 2020 and 2019, respectively.

Other (Income) Expenses, net. The decrease in Other (income) expenses, net of
$4.8 million relates primarily to losses on extinguishment of debt related to an
early repayment of pass-through financing obligation in 2019, with no such
comparable activity in the three months ended March 31, 2020.

The tax benefit at the statutory rate of 21.0% for 2020 was reduced by the
allocation of losses to noncontrolling interests and redeemable noncontrolling
interests of 15.1%, and increase in valuation allowance of 6.4% and increased by
other benefits of 3.4%. The tax benefit at the statutory rate of 21.0% for 2019
was reduced by the allocation of the losses to noncontrolling interests and
redeemable noncontrolling interests of 17.0%, and increase in valuation
allowance of 6.2% and offset by tax deductions from other miscellaneous items of
5.9%. The tax benefit was flat compared to the prior year.

The increase in net loss attributable to noncontrolling interests and redeemable
noncontrolling interests of $8.5 million was primarily a result of the addition
of five investment funds since March 31, 2019, as well as the HLBV method used
in determining the amount of net loss attributable to noncontrolling interests
and redeemable noncontrolling interests, which generally allocates more loss to
the noncontrolling interest in the first several years after fund formation.
Liquidity and Capital Resources

    As of March 31, 2020, we had cash of $286.4 million, which consisted of cash
held in checking and savings accounts with financial institutions. We finance
our operations mainly through a variety of financing fund arrangements that we
have formed with fund investors, borrowings, cash generated from our sources of
revenue, and proceeds from secured credit facilities arrangements with a
syndicate of banks for up to $265.3 million and from secured, long-term
non-recourse loan arrangements for up to $199.0 million. Our principal uses of
cash are funding our business, including the costs of acquisition and
installation of solar energy systems, satisfaction of our obligations under our
debt instruments and other working capital requirements.

    Our business model requires substantial outside financing arrangements to
grow the business and facilitate the deployment of additional solar energy
systems. The solar energy systems that are operational are expected to generate
a positive return rate over the term of the Customer Agreement, typically 20 or
25 years. However, in order to grow, we will continue to be dependent on
financing from outside parties. If financing is not available to us on
acceptable terms if and when needed, we may be required to reduce planned
spending, which could have a material adverse effect on our operations. While
there can be no assurances, we anticipate raising additional required capital
from new and existing investors. In connection with our cost reduction measures
discussed above implemented in response to COVID-19, we believe our cash,
investment fund commitments and available borrowings as further described below
will be sufficient to meet our anticipated cash needs for at least the next 12
months. The following table summarizes our cash flows for the periods indicated:

Operating Activities
During the three months ended March 31, 2020, we used $116.9 million in net cash
from operating activities. The driver of our operating cash outflow consists of
the cost of our revenue, as well as sales, marketing and general and
administrative costs. During the three months ended March 31, 2020, our
operating cash outflows were $35.3 million from our net loss excluding non-cash
and non-operating items. Changes in working capital resulted in a net cash
outflow of $81.6 million.
During the three months ended March 31, 2019, we generated $11.4 million in net
cash in operating activities. The driver of our operating cash inflow primarily
relates to payments received from customers as well as incentives. During the
three months ended March 31, 2019, our operating deferred revenue increased by
$95.5 million arising from a sale of the right to SRECs to be generated over the
next 10 to 15 years by a group of solar energy systems. In connection with the
sale, we repaid debt previously drawn against the rights to these SRECs, which
is reflected in our financing activities below. During the three months ended
March 31, 2019, our operating cash outflows were $42.8 million from our net loss
excluding non-cash and non-operating items. Changes in working capital resulted
in a net cash inflow of $54.3 million.
Investing Activities
During the three months ended March 31, 2020, we used $210.5 million in cash in
investing activities. The majority was used to design, acquire and install solar
energy systems and components under our long-term Customer Agreements.
During the three months ended March 31, 2019, we used $201.4 million in cash in
investing activities. The majority was used to design, acquire and install solar
energy systems and components under our long-term Customer Agreements.
Financing Activities
During the three months ended March 31, 2020, we generated $330.4 million from
financing activities. This was primarily driven by $153.7 million in net
proceeds from fund investors and $177.2 million in net proceeds from debt,
offset by $3.0 million in repayments under finance lease obligations.
During the three months ended March 31, 2019, we generated $195.5 million from
financing activities. This was primarily driven by $123.3 million in net
proceeds from fund investors and $71.8 million in net proceeds from debt, net of
debt issuance costs and repayments, offset by $3.0 million in payments for
finance lease obligations.

Debt and Investing Fund Commitments
As of March 31, 2020, we had committed and available capital of approximately
$717.8 million that may only be used to purchase and install solar energy
systems. We intend to establish new investment funds in the future, and we may
also use debt, equity or other financing strategies to finance our business. For
a discussion of the terms and conditions of debt instruments and changes thereof
in the period, refer to Note 8, Indebtedness, to our consolidated financial
statements included elsewhere in this Quarterly Report on Form 10-Q.
