I'll try sharing what I know though I have to admit it's limited. The specifics of SCTY's business model are somewhat confusing to me, though I get the gist of it. Prior to IPO I was really trying to wrap my head around how they're valuing leases, payments, etc and how to value the company but couldn't really figure it out. I became confident in the leadership and overall growth trajectory but confused about the specifics on how to model their valuation over time. I remember analysts were having a difficult time coming up with SCTY valuation as well around the IPO. Anyway, I eventually pulled the trigger (cost basis $14.50) mainly because the stock was rising and I didn't want an opportunity to invest in an Elon company get away (and Elon during pre-IPO had said that $13-15 for SCTY was a fair value for investors).
So, I guess I'll share some background and then go more into specifics.
First, I get a lot of my understanding of SCTY and solar from watching a ton of Elon Musk interviews and talks. He's bullish on solar as he thinks it will the one of the most popular ways to generate power in the future. When he suggested to his cousins to start a new solar company, the concept was to avoid manufacturing solar panels. He felt back then that China was/would subsidize the solar companies there and it would be too difficult to compete against them with panels. Further, Elon viewed the solar panels as more of a commodity item. They weren't that difficult to make. He saw the big challenge in solar was to integrate everything together in a cost-efficient manner - panels, inverter, racks, permits, installation, electrical work, monitoring, etc. So, when he funded SolarCity (and his cousins became CEO and COO), they sought to become the "Dell of solar". They wanted to pull all the parts together and integrate them in a very convenient, cost-effective manner for their customers.
Initially, this worked well. But over time, they encountered another problem and that was of financing. Not a ton of people could pay cash upfront for a new solar system. So, they started offering financing for solar systems, and things really started to take off.
So, in the beginning they were more like a construction company IMO. They would install the system, make their money, and move on to the next house. Later, when they started to offer financing, they wanted a way to benefit from the financing they offered in a long-term manner. So, they came up with a way to offer a 20-year lease to the customer (construction/components money provided by a 3rd party), the lease payments would go to SolarCity and then SolarCity would pay the 3rd party investor so they would get a decent return on their 20-year investment, and then after 20 years SolarCity would own the solar system on the roofs. So, after year 20, SolarCity would still be able to get payments from customers (if the customers wanted to continue) but they wouldn't have to pay a 3rd party investor anymore. So, it would be a ton of cash flow from years 20 on since the system is paid off. (I'm not sure if they've changed this more recently or not, but I think it's still the case they own the system outright after 20 years w/o obligation to any 3rd party.) So, the super long-term vision of SolarCity is to own the solar systems outright on a ton of houses and have this unending cash cow of a business. But in order to get there, they need to set up financing and make rather thin margins because they need to give the vast majority of lease payments to the original 3rd party investors in order keep existing investors and attract new ones.
This is why SolarCity now brands themselves as "selling energy." They're moving drastically away from solar system sales, and want to profit not just on the 20-year lease but even more so after the lease is over when they outright own the system. On another note, when they outright own the system the customer can benefit too because SolarCity can drastically reduce the costs of energy to the customer because they no longer have 3rd party payments to make from the financing. So, the customer gets much cheaper energy (than even during the 20 year lease) and SolarCity gets a ton of profit with little expense.
You can imagine the potential of this model when you think about 10 million homes with SolarCity solar systems on their roofs, and how after 20 years SolarCity would own the systems outright and the huge cash flow that can generate. For example, if SolarCity charges each house conservatively $100/month or $1200/year for electricity and expenses are $200/year for maintenance/monitoring. Revenue would be 1200 x 10mm = $12 billion a year with $2 billion in expenses. $10 billion profit. Multiply that by a 15 P/E multiple, then you've got a $150 billion market cap company.
But of course, this would take a very long time to achieve. Because not only would you need 10 million homes with SolarCity solar systems installed, you would need to wait 20 years until their leases are over before SolarCity can take advantage of outright ownership and huge profit margins. So, if it takes 15 years to get 10 million homes installed, another 20 years for lease payments (let's calculate 15 years because some would start during the 10mm home ramp-up), then you've got 30 years before they really start their amazing profit period. But that might be aggressive, so maybe let's say somewhere between 30-40 years. Amazingly, the Solarcity leadership really does seem to be thinking that far into the future. It's quite remarkable.
Now, I have my doubts if they're really going to be able to own the solar systems outright in 20 years. The reason being is because if raising financing becomes difficult, then they might need to hand over some of the post-20 year ownership/profit to the 3rd party financing parties who finance the 20 year lease. This will lower the crazy margins Solarcity gets then post-20-year-lease. And it could be possible that this is already what they're doing. I'm unclear on it.
Alright, so let's move on. How will SolarCity actually deliver on the 10mm houses in 15-20 years? Well, the whole business model of SolarCity is focused around convenience and cost-efficiency. They want to make it super convenient and cost-effective for the customer to switch to solar. That's why they've completely integrated the entire solar experience from sales, financing, installation, monitoring, and even post-installation energy efficiency home improvements. SolarCity uses their own people to design systems, install them, and fix them. It's all intended to create the most convenient customer experience, but also because over time it's the best way to drive down costs. In this way, SolarCity is very similar to SpaceX and Tesla Motors. All three companies integrate multiple aspects of their business and bring it altogether for a better customer experience but also to drive down costs.
Over time, SolarCity's competitive advantage will be cost-efficiency derived from integration. They will try to drive down costs in every angle of their business. Every penny will count. And they will be able to do this better than any of their competitors because they're the most focused on it. Other competitors don't have this 30-40 year vision and they aren't driven to complete integration like SolarCity. Over time, as SolarCity grows their cost advantage can grow too because they can take advantage of their current systems, personnel and also economies of scale. This is why SolarCity doesn't view other solar companies as their competitors. They view current electric utilities as their main competitors, and know that they need to provide a significantly cheaper source of electricity than them.
You mentioned net metering, and I do think this poses a significant challenge to SolarCity and all solar companies in the U.S. Currently net metering is helping to keep costs affordable for solar customers, but if net metering is revoked solar costs can increase (and they might need to install backup batteries, etc.). Solarcity is keenly aware of this challenge. Also, the federal tax credits for solar will be available until the end of 2016, after which solar systems could cost more to the end user w/o the tax credits. As a result, Solarcity's solution is to focus on cutting costs like crazy. They believe that they can cut costs (also helped by lower component costs as well) of the overall solar systems by enough to offset the effects of net metering removal and expiring tax credits. Whether they can do it remains a question. But nevertheless, they are religiously focused on it. If any large company in the residential solar installation sector can overcome the challenge of expiring tax credits and net metering, I think it's SolarCity.
I do think that there's opportunity in residential solar for straight solar system sales and installation. However, I don't see it likely for a large company to thrive in this space because it's a one-time revenue job. After a certain point, I think you might reach a saturation point where it's difficult to find cash buyers of new solar systems. So, I'm looking at the cash solar system sales and install business as a niche market. The main market will be leased/financed solar systems.
Regarding revenues and cash flows, I'm less clear on this aspect of their business than the concepts I've shared so far. Basically, it appears that everything starts with financing since demand for their systems isn't a problem. So, Solarcity raises investment funds (largely banks, companies, etc) and promises (or asserts) a certain return on investment. Depending on the type of fund (joint venture, lease pass-through, sale-leaseback... for more info see page 20-21 of
Q2 10q) Solarcity ends up receiving payment from their solar customers and giving a portion of that payment to the fund investor. However, it appears more complicated than that because Solarcity can lease the system to the fund investor, and then the fund investor sub-leases it to the customer (lease pass-through). Or they Solarcity sells the system to the fund investor, then leases it back from then and sub-leases to the end customer (sale-leaseback). Or the fund investor acquires the solar system together with Solarcity (joint venture) and it's then leased to the customer.
In
Solarcity's Q2 results summary:
- Estimated Nominal Contracted Payments Remaining of $1,409 million at June 30, 2013, up 15% from $1,222 million at March 31, 2013.
- Retained Value forecast of $662 million at June 30, 2013, equating to retained value per watt forecast of $1.27/W at June 30, 2013.
My understanding is that the estimated nominal contracted payment remaining is basically the amount of remaining payments SolarCity is to receive over the course of the 20-year leases. Basically, it's revenue. Then, SolarCity needs to pay the fund investors.
Retained value is what they're attributing to as the value of their portion of the 20 year lease payment but also of the value of the solar system after the 20-year lease is over. This is probably a better metric in trying to value the company. However, I'm unclear exactly how they're calculating the value of the solar systems in 20 years (it might be in the 10k/10q somewhere). Also, because some or much of the retained value is so far out (ie., 20+ years), then we need to discount that in whatever valuation modeling we do.
In their Q2 results, they say they have 54k energy contracts (64k total customers, I'm assuming that's because of cash sale systems). If the retained value is $662mm and we divide that by 54k energy contracts, then we've got $12,259 per contract in retained value. But I think this is skewed because commercial contracts are decreasing, while residential contracts are rapidly rising and residential contracts would be significantly lower. I would imagine the retained value on a residential contract would be between $5000-10000.
So, if SolarCity had 1 million customers (not sales, but energy contracts) and each of those contracts had a retained value of $5000, then the total retained value would be $5 billion. However, much of that sum would be very long-term (ie., post lease), so we would need to discount that value somehow in our modeling. But nevertheless, if Solarcity reaches their "1 million customers in 5 years) goal, then it's not far-reaching to see how they can have $5 billion in retained value in their leased/financed solar systems. If we up the average retained value to $7500/system then it would be $7.5 billion in retained value if they reach their 5 year goal. If we were trying to figure out a valuation, we would also need to factor in growth and future revenue that they will generate from new system sales. So, in 5 years how would I value the company if they did have 1 million contracts and they were growing strong? Hard to say. Maybe 10-20 billion. But that's a rough guess. I'd probably discount the $5-7.5 billion in retained value to $3 billion or so because it's so far out but one the other hand it's fairly reliable of an asset because it's not going anywhere. Then, I'd factor in current and future revenue into the valuation. If their on a trajectory to reach 10 million customers within 10 years after that point, then I'd say you'd need to tack on at least $10-20 billion to the valuation, so $13-23 billion. This is pretty much a random guess though and could be much more, or it could be less (Note: would love feedback here). The valuation multiple probably largely depends on how strong the growth trajectory is at the point of reaching 1mm customers.
It's interesting because SCTY doesn't seem to have made a big deal of this "1 million customer goal in 5 years" goal in the past. In fact, this is the first time I've seen mention of it. It's quite astounding because 1) it's a large # of customers (currently they're at 64k), and 2) it's a very short timeframe, just 5 years. Honestly, I don't know how they're going to accomplish this. It's quite mind-blowing.
Let's take a minute to track to model what this "1 million customers in 5 years" goal looks like. At the end of 2012, they had 40k energy contracts. By end of June 2013, they had 54k contracts. So, let's say they add another 36k contracts in the second half of 2013.
2013 - 50k new customers (total 90k)
2014 - 80k new customers (total 130k)
2015 - 120k new customers (total 250k)
2016 - 190k new customers (total 540k)
2017 - 270k new customers (total 810k)
2018 first half - 190k new customers (total 1mm)
Basically, Solarcity needs to grow like a weed in order to have any chance of reaching this "1 million customers in 5 years" goal. It almost seems crazy to even think about it, yet alone attempt it. this just goes to show the confidence in SolarCity's management (or their insanity):
1) They believe the residential solar industry is going to boom
2) They believe they can offer the most-compelling product (cost and convenience) to attract this kind of demand
3) They believe they can scale their company to meet this demand
Without these three beliefs, I don't see how SCTY management would even entertain such a lofty, crazy goal. Further, just entertaining a crazy "1 million customers in 5 years" goal means that the management really believes strongly in these three beliefs I've mentioned.
It's kind of strange to me that Solarcity doesn't promote this goal more to their investors. Their quarterly reports and conference calls seem very focused on what's going on this year, and they don't really point to a clear 5 year goal like this. It almost seems like they want to downplay things a bit. But then again, if they were trying to downplay things then why would they mention this goal in their
press release today.
On another note, it's amazing how long-term in view Elon Musk's companies are - SpaceX (colonization of Mars), Tesla Motors (electrification of entire auto market), and SolarCity (moving energy to solar). All of these companies goals are 20-40 years out. It's truly astonishing.
Alright, I'll end with a few disclaimers.
Please everyone, do your own research. Read the annual reports, quarterly reports, etc. and make up your own mind. Who knows, I could be making up everything if you don't see the facts yourself. Do your research and get as close to the companies you're considering to invest in as possible before making a decision (if it's a long-term investment). And remember I'm just an opinion.
Also, though I was bullish on SCTY when I bought and I'm bullish on SCTY long-term, I just want to be clear I'm not suggesting a specific price to buy at or time to buy. Getting in at the right price is extremely difficult to do. Sometimes you wait for it to dip, but it goes up. Other times you buy, and then it goes down. Buying and timing strategies is a whole other discussion. Further, the solar industry can be fickle too and sentiment can change in either direction. So, rather than a recommendation to buy SCTY I'd rather people take this as a conversation starter. I'd like to learn more about SCTY and also I'd like to see if there are major holes in my thinking. I'd love for others to chip in time and research and come up with a better way to model SCTY's valuation as well.
A few final random thoughts. It appears that SolarCity seems to be moving toward PPA (power purchase agreements) with their residential customers. I'm unclear if this is just a repackaged lease or if this somehow differs from a 20 year traditional lease. Would love if someone who knows can clarify.
Lastly, their insider ownership seems strong (see
proxy statement). And Elon Musk owns 27% of the company.
