A Leader In Cost Efficiency AS MEASURED IN COST PER WATT $2.94 $2.85 $3.08 $2.98 $2.88 $2.94 $2.95 $3.15 $3.11 Q2 '16 Q3 '16 Q4 '16 Q1 '17 Q2 '17 Q3 '17 Q4 '17 Q1 '18 Q2 '18 Cost efficiency is key to sustainability and market growth. Lowering cost per watt increases the margin from our system sales at a given price and allows our project funding to cover more of the costs of installation of PPAs and leases. This frees operating cash flows to facilitate faster growth, market expansion, and increased enterprise value. Installation & Equipment $1.85 Sales & Marketing 0.85 General & Administrative 0.41 23

Operating cash flows from existing customers and systems sales are increasing over time, and combined with our project level financing allow us to be cash flow accretive. In addition to increasing cash balances, we are accumulating future cash flows and increasing overall value to shareholders. 24

Creating Long-Term Value What is Estimated Net Retained Value? ESTIMATED NET RETAINED VALUE ($M) $628 $650 $639 $652 $690 $723 $767 $782 $836 Estimated Net Retained Value represents the asset value that would remain after repaying all debt. It is calculated by taking Estimated Gross Retained Value, subtracting all debt, and adding back cash & cash equivalents. Q2 '16 Q3 '16 Q4 '16 Q1 '17 Q2 '17 Q3 '17 Q4 '17 Q1 '18 Q2 '18 Why does Vivint Solar use Estimated Net Retained Value to measure long-term value creation? ESTIMATED NET RETAINED VALUE PER SHARE $5.86 $5.98 $5.80 $5.90 $6.04 $6.30 $6.67 $6.78 $7.05 Estimated net retained value captures the residual asset value that is available to equity holders at a given point in time. As Vivint Solar continues to develop and retain ownership of solar systems, we believe that estimated net retained value will increase over time, resulting in increasing value to our shareholders.

Glossary Installations Represents the number of solar energy systems installed on customerpremises. Megawatts (MWs) Represents the DC nameplate megawatt productioncapacity. MW Installed MW Booked Represents the aggregate megawatt nameplatecapacity of solar energy systems for which panels, inverters, and mounting and racking hardware have been installed on customer premises in the period. Represents the aggregate megawatt nameplatecapacity of solar energy systems that were permitted during the period net of cancellations in the period. Estimated Retained Value Represents the net cash flows, discounted at 6%, that Vivint Solar expects to receive from customers pursuant to long-term customer contracts net of estimated cash distributions to fund investors and estimated operating expenses for systems installed as of the measurement date. For purposes of the calculation, Vivint Solar aggregates the estimated retained value from the solar energy systems during the typical 20-year term of Vivint Solar s PPAs and Leases, which Vivint Solar refers to as estimated retained value under energy contracts, and the estimated retained value associated with an assumed 10-year renewal term following the expiration of the initial contract term, which Vivint Solar refers to as estimated retained value of renewal. To calculate estimated retained value of renewal, Vivint Solar assumes all contracts are renewed at 90% of the contractual price in effect at the expiration of the initial term. Estimated Retained Value per Watt Undeployed Tax Equity Financing Capacity Is calculated by dividing the estimated retained value as of the measurement date by the aggregate nameplate capacity of solar energy systems under long term customer contracts that have been installed as of such date, and is subject to the same assumptions and uncertainties as estimated retained value. Represents a forecast at the amount of megawatts that can be deployed based on committed available tax equity financing for PPAs and Leases. Nominal Contracted Payments Remaining Equals the sum of the remaining cash payments that Vivint Solar s customers are expected to pay over the term of their agreements for systems installed as of the measurement date. For a power purchase agreement, Vivint Solar multiplies the contract price per kilowatt-hour by the estimated annual energy output of the associated solar energy system to determine the estimated nominal contracted payments. For a customer lease, Vivint Solar includes the monthly fees and upfront fee, if any as set forth in the lease. 31
