Recent thoughts on Solar PPA/lease vs Purchase
Also, in 5-10 years time IMO the leasing model will be dead. Residential systems will be very cheap to buy and there will be mortgage like products out there with low interest rates for those who can't afford to pay up front. There will be no reason to lease a system anymore.
I've thought about this a lot. I personally don't think the leasing model will be dead in 5-10 years. I there's there's a strong likelihood that it will remain indefinitely. I liken it to a subscription model where people are paying for a service. But let me qualify this some.
I understand the appeal to outright purchase a solar system. I've looked into both leasing/ppa and purchasing, and if one has cash to spend the purchasing works out to be the better deal. The thing is the market is so big and while many people will purchase, I think the PPA model might address a larger market than purchasing (as it is currently doing so). But I think the PPA model needs to grow and adapt in order to do so. Perhaps Solarcity's bigger competition might be some companies that offer affordable financing to purchase and are as relentless as SolarCity to drive down the costs of solar. But SolarCity will have plenty of time to adapt and make their PPA program much better than it is now.
I actually had a great idea (at least in my opinion) yesterday when I was talking a walk. I was thinking how can SolarCity scale their PPA model and compete effectively if/when solar becomes much more affordable to outright purchase and there are compelling financing vehicles available to do so. Here were my ideas:
1. SolarCity should adapt their model to allow the customer to scale up or down their system when they want.
The idea is similar to Amazon Web Services (AWS) which allows developers to scale up or down computing power whenever they want. In SolarCity's case, if they can allow a customer to start using their service by installing a very small system (ie., 2kW solar system) just so that the customer can avoid the high tiers their paying (ie., I'm paying $0.33 for tier 3 energy). And then SolarCity could allow the customer to "scale up" the system whenever they want. In other words, if the customer wants to add solar power, SolarCity would come by and install more panels (of course this could be complicated with mounting, permits, install... but this is the magic that SCTY will have to create and solve). So, if I wanted to scale up my 2kW system to 5kW, SCTY would be able to do so seamlessly (they would just come by within a month or so and do it in a few hours). Now, this is going to take some major innovation from SolarCity to be able to do this type of "scaling" or "adding" to an existing solar system in a cost-efficient manner. Perhaps they can make their mounting system more modular (if it isn't already enough so) and they can streamline the permit processes even more.
2. SolarCity should offer customers to remove the solar system at any time at no cost.
So, if I wanted to remove my solar system, I should be able to request that from SolarCity and they do it (ie., within a month) and at no cost. Sure, it will cost SCTY to do so (man-hours, etc) but they could recycle the panels, inverter, mounts, etc.
The reason why I think SolarCity needs to offer this is because there are situations where a customer might want that kind of flexibility to remove the system. One example is I might want to rent out my house but I don't think the tenant will appreciate/use solar (who knows who's out there). Another example, if if I'm selling my house and the next owner doesn't have good credit so it might be difficult to transfer the currently structured PPA over to the new owner. In this case, I could just request SolarCity to remove the system at no cost to me.
3. IMO the ability to scale up/down a solar system and the ability to remove it at no cost would allow expand SolarCity's addressable market.
One example, is I would immediately get started with SolarCity and have them install a 2kW system at my house and get out of any Tier 2/3 usage, so my electricity bill will drop substantially. I'm thinking of perhaps moving in the next year or so, so that's why I wouldn't want to buy/purchase a system outright. And if SolarCity could offer this on-demand scaling service where I could scale up or down my system size at anytime (and remove it at no cost), then I probably would be tempted to forgo purchasing a system completely and just use SolarCity. Sure there will always be people who will outright purchase their system, but if SolarCity's PPA program offered this scalable optionality (with no-cost removal) then it would make it much more appealing to even more people.
Imagine if SolarCity offered this scaling up/down feature, no-cost removal and no-commitment approach. SolarCity could get people started with a small 2kW system to get people off high utility tier usage. And if it was no-commitment (no-cost removal) and free scaling up/down, I would imagine a flood of people (1m+ this year alone) would take SolarCity up on this offer.
Now some people might say that what I'm proposing is impractical or impossible. But as SolarCity scales, their cost improves and their able to improve their product services. What I'm proposing might not happen overnight but it might be where SolarCity is headed. Especially so, since Elon Musk is SolarCity's chairman and he likes to view things with First Principle. And what I'm proposing is what I think solar ought to be:
- no commitment, no initial cost
- can start off with a small 2kW system (or even smaller) to get off high utility tiers
- can scale up my system at anytime for no cost
- can scale down my system at anytime for no cost
- can have my system removed at any time for no cost
Compare this to outright purchasing/financing a solar system. Outright purchasing/financing a solar system might be the better option for those who are confident they're going to be staying in their current house for the next 10 years. But for those who think they could move in 2-5 years, they might want more flexibility and convenience. Also, purchasing/financing could require additional complexity (longer applications, credit checks, etc).
Right now, SolarCity probably doesn't need to focus on offering what I'm proposing since their currently addressable market is so huge that they just need to provide energy for less than what the utility offers it for. As long as they do that they can probably continue to grow rapidly for the next several years. But at some point as solar costs come down, SolarCity will need to make their product/service more compelling (more convenient, more flexible, etc) than what will be offered for those who outright purchase/finance their systems from other companies. I'm fairly confident that SolarCity will be able to do this... especially with Elon as Chairman and SolarCity following the Musk Ethos of relentlessly cutting costs and improving their product/service.
