Solar leases and power purchase agreements (PPAs) are two 3rd-party ownership options that allow consumers to install solar energy systems without the upfront cost.
The cost of a PV system depends on the system size, equipment options (panels and inverters), permitting costs, and labor costs. Prices vary depending on other factors as well, such as whether your home is new, where the system is installed on your premise, the PV manufacturer, and other factors. For example, the total average cost of an installed residential PV system under the California Solar Initiative is $8.70 per Watt (including installation, as of January 2011). That translates to about $34,800 for a four-kilowatt system, the average size of a residential installation.

Instead of putting up $30,000 or more to buy solar panels , why not just rent them? A few companies are offering to install and maintain solar panels in exchange for a monthly fee. The idea is based on the purchase power agreements used by businesses. In this type of agreement, the company owns and maintains the solar panels and sells the electricity back to the homeowner. At the end of the rental period, homeowners can extend their lease, buy the system, or have it removed. The arrangement protects homeowners from rising fuel prices because their monthly cost is locked-in for several years.
