SolarCity, the largest US rooftop PV installer, is making substantial progress in its planned shift to selling more PV systems outright rather than leasing them out to customers, giving a boost to its third-quarter results.

Like many companies in the challenged solar market, SolarCity is shifting its immediate tactics to emphasise cash flow and nearer-term profits – which for a rooftop solar installer means selling more systems for cash as opposed to signing long-term leases or PPAs with homeowners that pay out over many years.
