SolarCity: Rapid Innovation case study is a Harvard Business School (HBR) case study written by Stefan Reichelstein, Davina Drabkin. The SolarCity: Rapid Innovation (referred as “Solarcity Solar” from here on) case study provides evaluation & decision scenario in field of Finance & Accounting. It also touches upon business topics such as - Value proposition, Branding, Financial management, Mergers & acquisitions.

The net present value (NPV) of an investment proposal is the present value of the proposal’s net cash flows less the proposal’s initial cash outflow. If a project’s NPV is greater than or equal to zero, the project should be accepted.

NPV = Present Value of Future Cash Flows LESS Project’s Initial Investment

Case Description of SolarCity: Rapid Innovation Case Study

Between 2010 and 2012, SolarCity experienced tremendous growth in an industry that was generally perceived to be struggling. Many other solar start-ups were failing-Solyndra, which had received a $535M loan from the U.S. government, was the highest profile failure, declaring bankruptcy in September, 2011. Lyndon Rive noted, "Investors have been burned so badly from the solar sector. We've faced that stigma while selling our company to investors." Despite that burn, however, SolarCity went forward with an initial public offering (IPO) in December of 2012 at an IPO price of $8.00 per share. By end of the second quarter, 2014, SolarCity operated in 15 states and the District of Columbia and boasted 140,000 customers. It controlled 36 percent of the residential solar market but had never posted a profit-in 2013 it had a net loss of almost $152 million. SolarCity's growth, however, drove the stock price up, hitting a high of $86.14 in February 2014. The company's continued lack of positive accounting earnings, yet impressive stock returns, left analysts and industry observers wondering: Was SolarCity already making money on installations like the Partnership Flip Model or was the company's share price primarily a bet on the future with lower solar installations costs? This case describes SolarCity's business model and summarizes key issues in the solar industry. It looks at tax equity financing, detailing the Partnership Flip Model which SolarCity used for about two thirds of the funds it had raised by 2014. The Partnership Flip Model is represented in an Excel spreadsheet that students manipulate to understand the implications of various factors.

Capital Budgeting Approaches

Methods of Capital Budgeting

There are four types of capital budgeting techniques that are widely used in the corporate world –

1. Payback Period
2. Profitability Index
3. Internal Rate of Return
4. Net Present Value

Apart from the Payback period method which is an additive method, rest of the methods are based on Discounted Cash Flow technique. Even though cash flow can be calculated based on the nature of the project, for the simplicity of the article we are assuming that all the expected cash flows are realized at the end of the year.

Discounted Cash Flow approaches provide a more objective basis for evaluating and selecting investment projects. They take into consideration both –

1. Timing of the expected cash flows – stockholders of Solarcity Solar have higher preference for cash returns over 4-5 years rather than 10-15 years given the nature of the volatility in the industry.
2. Magnitude of both incoming and outgoing cash flows – Projects can be capital intensive, time intensive, or both. Solarcity Solar shareholders have preference for diversified projects investment rather than prospective high income from a single capital intensive project.

Formula and Steps to Calculate Net Present Value (NPV) of SolarCity: Rapid Innovation

NPV = Net Cash In Flowt1 / (1+r)t1 + Net Cash In Flowt2 / (1+r)t2 + … Net Cash In Flowtn / (1+r)tn
Less Net Cash Out Flowt0 / (1+r)t0

Where t = time period, in this case year 1, year 2 and so on.
r = discount rate or return that could be earned using other safe proposition such as fixed deposit or treasury bond rate. Net Cash In Flow – What the firm will get each year.
Net Cash Out Flow – What the firm needs to invest initially in the project.

Step 1 – Understand the nature of the project and calculate cash flow for each year.
Step 2 – Discount those cash flow based on the discount rate.
Step 3 – Add all the discounted cash flow.
Step 4 – Selection of the project

Why Finance & Accounting Managers need to know Financial Tools such as Net Present Value (NPV)?

In our daily workplace we often come across people and colleagues who are just focused on their core competency and targets they have to deliver. For example marketing managers at Solarcity Solar often design programs whose objective is to drive brand awareness and customer reach. But how that 30 point increase in brand awareness or 10 point increase in customer touch points will result into shareholders’ value is not specified.

To overcome such scenarios managers at Solarcity Solar needs to not only know the financial aspect of project management but also needs to have tools to integrate them into part of the project development and monitoring plan.

Calculating Net Present Value (NPV) at 15%

After working through various assumptions we reached a conclusion that risk is far higher than 6%. In a reasonably stable industry with weak competition - 15% discount rate can be a good benchmark.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 15 %	Discounted Cash Flows
Year 0	(10007410)	-10007410	-	-
Year 1	3459910	-6547500	3459910	0.8696	3008617
Year 2	3958479	-2589021	7418389	0.7561	2993179
Year 3	3969244	1380223	11387633	0.6575	2609842
Year 4	3249912	4630135	14637545	0.5718	1858148
TOTAL					10469786

The Net NPV after 4 years is 462376

(10469786 - 10007410 )

Calculating Net Present Value (NPV) at 20%

If the risk component is high in the industry then we should go for a higher hurdle rate / discount rate of 20%.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 20 %	Discounted Cash Flows
Year 0	(10007410)	-10007410	-	-
Year 1	3459910	-6547500	3459910	0.8333	2883258
Year 2	3958479	-2589021	7418389	0.6944	2748944
Year 3	3969244	1380223	11387633	0.5787	2297016
Year 4	3249912	4630135	14637545	0.4823	1567280
TOTAL					9496498

The Net NPV after 4 years is -510912

At 20% discount rate the NPV is negative (9496498 - 10007410 ) so ideally we can't select the project if macro and micro factors don't allow financial managers of Solarcity Solar to discount cash flow at lower discount rates such as 15%.

Acceptance Criteria of a Project based on NPV

Simplest Approach – If the investment project of Solarcity Solar has a NPV value higher than Zero then finance managers at Solarcity Solar can ACCEPT the project, otherwise they can reject the project. This means that project will deliver higher returns over the period of time than any alternate investment strategy.

In theory if the required rate of return or discount rate is chosen correctly by finance managers at Solarcity Solar, then the stock price of the Solarcity Solar should change by same amount of the NPV. In real world we know that share price also reflects various other factors that can be related to both macro and micro environment.

In the same vein – accepting the project with zero NPV should result in stagnant share price. Finance managers use discount rates as a measure of risk components in the project execution process.

Sensitivity Analysis

Project selection is often a far more complex decision than just choosing it based on the NPV number. Finance managers at Solarcity Solar should conduct a sensitivity analysis to better understand not only the inherent risk of the projects but also how those risks can be either factored in or mitigated during the project execution. Sensitivity analysis helps in –

What will be a multi year spillover effect of various taxation regulations.

What are the key aspects of the projects that need to be monitored, refined, and retuned for continuous delivery of projected cash flows.

Understanding of risks involved in the project.

What can impact the cash flow of the project.

What are the uncertainties surrounding the project Initial Cash Outlay (ICO’s). ICO’s often have several different components such as land, machinery, building, and other equipment.

Some of the assumptions while using the Discounted Cash Flow Methods –

Projects are assumed to be Mutually Exclusive – This is seldom the came in modern day giant organizations where projects are often inter-related and rejecting a project solely based on NPV can result in sunk cost from a related project.

Independent projects have independent cash flows – As explained in the marketing project – though the project may look independent but in reality it is not as the brand awareness project can be closely associated with the spending on sales promotions and product specific advertising.
