Leasing is just one form of financing SolarCity provides. They mostly offer power purchase aggreements (PPA) wherein the customer pays per kWh used. In the US, the delinquency rate that SolarCity experiences is substantially lower than for mortgages, which have the lowest rates among consumer debt. Customers poy their PPA bill to SolarCity because they want to continue using power and utility rates are higher. So while there may be temptation to skip a car payment or even a mortgage payment, the power bill is one of the very last a person might skip. There is a certain amount of credit risk with any service contract. The state grid offering lower to an customer has just as much credit risk as SolarCity. Naturally, SolarCity would want to pull credit scores on any customer, whether in the US or India and screen out poor credit risks. SolarCity city has also develop an innovative new solar loan which as I recall ties interest payments to the consumption of energy, which protects the customer from the risk of underperformance of the system. In return for abslrbing this risk, SolarCity realizes higher retained value per watt on this product. The key point here is that SolarCity is very creative about developing its financial products. They offer outright sales, solar loans, monthly leases, PPAs, and on the deposit side they have solar bonds which pay better than CD rates to retail investors. Which products are most suitable in India remains to be seen, even so each product would have to be constructed to work within India's legal, tax and regulatory framework. This is a given. There may even be subtle issues that motivate innovation of a totally new financial product. Off the top of my head, there may be contexts where prepaid plans make sense. For example, a prepaid phone plan could have an embedded prepaid charging plan. Here SolarCity could contract with the company selling the prepaid phone credits to pag them so that the phone user may charge at SolarCity charging stations. This may seem pretty far fetched in places like the US or Australia, but in super remote and grid isolated places in India there may be lots of cell phones and other portable electic devices, but no place nearby to charge them. I'm not saying this is a plum market, but there may a context for it. Any in case, SolarCity is very innovative financially, so I am confident they can figure out what will work best in any particular context. In the view of Robert Shiller, all finance is technology. So it comes down to figuring out how to make it work.
