Exhibit 99.1

SolarCity Third Quarter 2014 Shareholder Letter

Nominal Contracted Payments Remaining Up 137% Y/Y to $4.1 Billion

Retained Value of $2.2 Billion

Record 230 MW Booked and 137 MW Deployed

November 5, 2014

Dear Fellow Shareholders:

Our long-term value creation for shareholders has never been stronger. Our Estimated Nominal Contracted Payments Remaining has grown to $4.1 billion and our forecast of Retained Value to $2.2 billion as of the end of the third quarter of 2014.

We continued to experience unprecedented demand in the quarter, while greater scale and efficiencies drove our unit costs to new lows. Total MW Booked increased 154% Y/Y to 230 MW and total MW Deployed grew 77% Y/Y to 137 MW with residential MW deployed up 100% Y/Y to 119 MW. Additionally, our total blended cost declined (11%) Y/Y to $2.90 per watt. We are very pleased with this execution, and we remain on track to reach our goal to roughly double our volume every year and lower our total cost to $2.50 per watt by 2017.

When we started SolarCity eight years ago, we set out with the earnest goal to help transform the way energy is delivered in the 21st century through cleaner, more affordable, distributed solar generation. Ultimately, our aim is to grow distributed solar into the largest source of electricity generation in the United States—greater than coal, natural gas, nuclear or any other source. At less than 1% penetration today, this means hundreds of thousands of MW of new distributed solar. Thus, we cannot sit idly by and wait for the market to gradually open up. Rather, we strongly believe we must proactively do everything possible to drive this market forward by improving distributed solar economics. We have to innovate in every aspect of the value chain—customer acquisition, installation, logistics, technology, and finance—to continue to lower the cost of solar energy to the broader public and ultimately make solar affordable on an unsubsidized basis. From Silevo and Zep technology innovation to MyPower and Solar Bonds, we have embarked on a number of new initiatives over the last few months to broaden the addressable market of distributed solar and further differentiate SolarCity as an energy provider. In our inaugural Quarterly Shareholder Letter, we will discuss these initiatives and how they fit into our broader strategic vision and lay the groundwork for sustained growth and value creation.

MyPower: Breaking New Barriers in Access to Solar

In October, we launched our most important new product since the Solar Lease in 2008. MyPower is a new solar loan product that offers customers the benefits of ownership and lower monthly energy bills with no upfront investment. We simply sell the customer the solar system and provide a 30-year loan to finance the system. Interest and principal repayments are structured like a PPA that provides customers a discount to their local utility rate. At our introductory interest rate of 4.5%-5.0%, our first loan customers will be able to own the system and lower their monthly energy bills from the start.

MyPower is also significant because it is our first product not financed through a tax equity financing fund. The unique product structure allows us to focus on efficiently financing customer payments without an intermediate tax equity investor. In a future market environment without tax credits or subsidies, this will be the most effective way to finance our business. This advance in financing is an amazing accomplishment and a critical step towards our long-term goal of opening up the solar market to the masses.

Further Innovation in Solar Technology and Finance

Our efforts to further differentiate SolarCity through technology also continued to make progress in the third quarter. Following our June announcement of the agreement to acquire Silevo, we officially closed the acquisition in September and broke ground on what is expected to be the largest solar manufacturing facility in the Western Hemisphere in partnership with the state of New York. We continue to expect our first 1 GW facility to be operating at full capacity in 2017, and to lay the groundwork for a step-change reduction in the cost of solar energy.

Demonstrating the extended benefits of last year’s acquisition of Zep Solar, we introduced two key new product innovations last month that we expect to increase installation speeds, lower costs and expand the addressable U.S. market for commercial solar even further. ZS Peak—SolarCity’s new lightweight, “snap together” mounting system for commercial flat roofs—can increase the generation capacity that can be installed on each roof by up to 20% - 50%. ZS Beam allows solar panels to be attached to carports faster, more safely and at a lower cost by eliminating unnecessary components and enabling installation from below the support structure, instead of above. In tandem, these new products will make it possible for more businesses, schools and government organizations to use solar electricity generated from their rooftops or parking lots and pay a lower rate for it than they pay for electricity from their utility company.

Finally, we also launched the nation’s first registered public offering of Solar Bonds for retail investors and a new online investment site (solarbonds.solarcity.com) to make them available directly to consumers. Solar Bonds allow the broader public to participate and invest in distributed solar’s growth and we hope it will also increase our Solar Ambassador advocates across the country.

Operations Throughput Hits New Highs as Cost Declines Continue

Our operations team continued to scale throughput to new heights with deployments up 77% Y/Y to 137 MW in the third quarter, and our plans to open 20 new operations centers around the country further expands our deployment capacity in Q4 2014. Our installation crew headcount ended the quarter up over 78% year-over-year and their efficiency continued to improve. Our best performing installation crews—Barracuda, Batman, Chevelle, GTO, Lake Placid, and Mustang—installed around 250 kW a month over the last quarter—close to two residential systems per working day. We remain laser-focused on reducing costs and our cycle times while maintaining our high quality standards.

Greater efficiencies and higher throughput helped push our costs down to new lows. Installation cost of $2.19 per watt declined (4%) from our Q2 2014 cost of $2.29 per watt and (17%) Y/Y. With sales cost essentially flat Q/Q at $0.50 per watt and G&A down (21%) Q/Q to $0.21 per watt, total cost per watt declined to $2.90 per watt from $3.03 per watt in Q2 2014, better than our expectations and pushing us ahead of plan on our cost roadmap. Reconciliation of our cost per watt to our GAAP financial statements is available on the investor relations section of our website (at investors.solarcity.com).

Our goal is to achieve a blended installation cost per watt of $1.90 per Watt in 2017 and SG&A cost of less than $0.60 per watt for a total all-in cost goal of better than $2.50 per watt. This would enable us to continue to deliver distributed solar to a broad section of the country while still generating attractive returns after the current planned reduction in the ITC in 2017.

Strong Foundation Underpinning Revenue and Cash Flow Outlook over the Next 30 Years

With cumulative MW deployed at 894 MW at the end of the quarter, we now operate a portfolio of power producing solar systems with the capacity to produce approximately 125 million megawatt-hours per year. In August, we hit a new record of 3.6 GWh on two separate days.

We now have more than 168,000 customers, up 105% from over 82,000 a year ago. To put this in perspective, we now have more customers than the No. 2 utility in Connecticut, the No. 1 utility in Washington D.C. as well as the sixth largest retail electric utility in California. While these are impressive figures, our penetration in the 15 markets we serve still remains under 1%, providing plenty of room to continue to grow at a rapid rate.

As Estimated Nominal Contracted Payments Remaining represents future cash receipts, Retained Value represents the unlevered discounted net cash flow forecast to SolarCity after all project-related costs before the payment of any debt service. Our Retained Value forecast at September 30, 2014 was $2.2 billion. This is calculated by adding up (1) all expected cash receipts from the

customer over the 30-year life of the system (assuming renewal for PPAs/leases) including performance-based incentives, and subtracting (2) all operations & maintenance expenses (including inverter replacement, insurance, and administrative costs) as well as (3) all liabilities due to our joint venture financing partners over the next few years, and (4) discounting to the current period. The retained value calculation is an illustration of our forecasted value of all of our customer energy contracts at a point in time and assumes no further development activity, which as we all know should not be the case!

GAAP operating lease and solar energy systems incentive revenue was $52 million in the third quarter of 2014. With solar energy system sale and components revenue of $6 million, total GAAP revenue was $58 million. Operating lease and solar energy incentive gross margin was 51%. Total GAAP operating expenses were $100 million with sales and marketing of $56 million (including $3 million of amortization of intangibles and $4 million in stock compensation), G&A of $40 million ($11 million in stock compensation), and R&D of $4 million ($2 million in stock compensation). Operating expenses included a one-time $6 million benefit related to insurance proceeds.

Financing and Normalized Net Cash Flow

Looking Ahead

Strong execution in the third quarter has provided us with excellent momentum heading into the end of the year. For the fourth quarter of 2014, we expect MW Deployed between 179 MW and 194 MW, an increase of 36% sequentially and 81% year-over-year, at the midpoint. For the full year 2014, we now expect to deploy between 505-520 MW, up 83% year-over-year at the midpoint.

With regard to Q4 2014 GAAP guidance, we expect Operating Lease and Solar Energy Systems Incentive Revenue of $47 million - $52 million as the seasonal decline in solar production from October through the start of winter in December should be offset in large part by a higher base of operating lease MW Deployed. Solar Energy System and Component Sale Revenue is expected to range between $20 million and $24 million.

Operating Lease and Solar Energy Systems Incentive Gross Margin is expected to range between 35%-40% (or 45%-50% excluding the impact of approximately $5 million in amortization of intangibles). Driven largely by an increase in sales headcount, we expect Operating Expenses of $118 million - $128 million (including between $22 million and $28 million in non-cash amortization of intangibles and stock compensation expense). In turn, Non-GAAP EPS (before Income (Loss) Attributable to Noncontrolling Interests and Redeemable Noncontrolling Interests)* is expected to range between ($1.25) – ($1.35).

Looking further ahead, based on greater confidence in our run rate and backlog heading into next year, we are increasing the low-end our 2015 guidance and now expect MW Deployed of 920 MW – 1.0 GW. Assuming the midpoint of our guidance, we will have accumulated over 2 GW Deployed at the end of 2015 generating energy at a run rate of approximately 2.8 TWh per year.

Even with this tremendous growth, we will be barely scratching the surface of the addressable market. The U.S. consumes over 4,000 TWh per year, suggesting that our 2015 output would represent less than 0.1% of our country’s total electricity demand. Throughout the last few years, we have made tremendous progress towards our goal to make distributed solar a plurality of electricity generation, but much of the heavy lifting is still ahead of us. We thank all of our customers, advocates and shareholders for their support along this journey, and we look forward to achieving our goal together in the years ahead.

* Non-GAAP Earnings per Share [EPS] Before Noncontrolling Interests

While GAAP EPS is based upon net income (loss) attributable to common stockholders, we also report non-GAAP EPS based upon net income (loss). The only difference between GAAP EPS and non-GAAP EPS is the sole line item net income (loss) attributable to non-controlling interests and redeemable noncontrolling interests.

Under GAAP accounting, we report net income (loss) attributable to noncontrolling interests and redeemable noncontrolling interests to reflect our joint venture fund investors’ allocable share in the results of these joint venture financing funds. Income (loss) attributable to noncontrolling interests and redeemable noncontrolling interests is calculated based primarily on the hypothetical liquidation at book value, or HLBV method, which assumes that the joint venture funds are liquidated at the reporting date, even though liquidation may or may not ever occur. Additionally the returns that will be allocated to the investors over the expected terms of the funds may differ significantly from the amounts calculated under the HLBV method. Accordingly, we also report non-GAAP EPS based on earnings before net income (loss) attributable to noncontrolling interests and redeemable noncontrolling interests per share, which we view as a better measure of our operating performance.

According to this definition, non-GAAP earnings before noncontrolling interests and redeemable noncontrolling interests per share was ($0.75).

See below for a reconciliation of GAAP EPS to non-GAAP EPS.

Retained Value Sensitivities:

The following tables provide quantitative sensitivity analyses of our estimates of Retained Value Under Energy Contract, Retained Value Renewal, Retained Value, and Retained Value per Watt as of September 30, 2014 on our and alternate assumptions.

Retained Value Forecast ($M)		Retained Value Forecast ($/Watt)
Retained Value Under Contract ($M)		Retained Value of Renewal ($/Watt)

Definitions:

“MW” or “megawatts” represents the DC nameplate megawatt production capacity.

“Backlog” represents the aggregate megawatt capacity of solar energy systems not yet deployed as of the date specified pursuant to Energy Contracts and contracts for solar energy system direct sales executed as of such date.

“Customers” includes all residential, commercial and government buildings where we have installed or contracted to install a solar energy system, or performed or contracted to perform an energy efficiency evaluation or other energy efficiency services.

“Energy Contracts” includes all residential, commercial and government leases and power purchase agreements and consumer loan agreements pursuant to which consumers use or will use energy generated by a solar energy system that we have installed or contracted to install. For landlord-tenant structures in which we contract with the landlord or development company, we include each residence as an individual contract. For commercial customers with multiple locations, each location is deemed a contract if we maintain a separate contract for that location.

“MW Booked” represents the aggregate megawatt production capacity of solar energy systems pursuant to customer contracts signed (with no contingencies remaining) during the applicable period net of cancellations during the applicable period. This metric includes solar energy systems booked under Energy Contracts as well as solar energy system direct sales.

“MW Deployed” represents the megawatt production capacity of solar energy systems that have had all required building department inspections completed during the applicable period. This metric includes solar energy systems deployed under Energy Contracts as well as for solar energy system direct sales.

“Nominal Contracted Payments Remaining” represents our estimate of the sum of cash payments that are customers are obligated to pay us under our Energy Contracts over the remaining term of such contracts. This metric includes Energy Contracts for solar energy systems deployed and in Backlog. As an example, if a customer is 2 years into her 20 year contract, then 18 years of contract payments remain. As an additional example, if a customer chose to pre-pay her Energy Contract, then it is included in estimated Nominal Contracted Payments Remaining only while it is in Backlog as the pre-payment has not been received. Payments for direct sales are not included.

“Retained Value” forecast represents the sum of both “Retained Value under Energy Contract” and “Retained Value Renewal.” Retained Value under Energy Contract represents our estimate of the forecasted net present value at a discount rate of 6% of Nominal Contracted Payments Remaining and estimated performance-based incentives allocated to us, net of amounts we are obligated to distribute to our fund investors, upfront rebates, depreciation, renewable energy certificates, solar renewable energy certificates and estimated operations and maintenance, insurance, administrative and inverter replacement costs, based on contractually agreed amounts as well as historic expenses. This metric includes Energy Contracts for solar energy systems deployed and in Backlog. Retained Value Renewal represents our estimate of the forecasted net present value at a discount rate of 6% of the payments we would receive upon renewal of all Energy Contracts (excluding consumer loan agreements, which have a 30 year term) through a total term of 30 years at a rate equal to 90% of the contractual rate in effect at expiration of the initial term, net of estimated operations and maintenance, insurance, administrative and inverter replacement costs, based on contractually agreed amounts as well as historic expenses. This metric includes Energy Contracts (excluding consumer loan agreements) for solar energy systems deployed and in Backlog. We assume renewal due to both (1) a higher life expectancy of the equipment used in our solar energy systems (typically 30 years or more) vs. a contract term (typically 20 years) and (2) our assumption utility retail rates continue to increase at their historic pace and our expectation that the price of our energy contracts will continue to represent an economic incentive for our customers to renew their contracts.

“Retained Value per Watt” is computed by dividing cumulative retained value as of such date by the sum of total MWs deployed under Energy Contracts as of such date plus MWs booked under Energy Contracts as of such date but not yet deployed.

“Undeployed Tax Equity Financing Capacity” represents a forecast of the amount of MW that can be deployed based on committed available tax equity financing for Energy Contracts.
