In experimental form they have even been used to power automobiles in races such as the [[World solar challenge]] across [[Australia]]. Many yachts and land-vehicles use them to charge on-board batteries away from grid power. Large-scale incentive programs, offering financial incentives like the ability to sell excess electricity back to the public grid, have greatly accelerated the pace of solar PV installations in Spain, Germany, Japan, the United States and other countries.
 
Even with these incentives, the start-up costs associated with solar electric panels currently push their likely 'pay-back' period into decades rather than years in applications where conventional "grid" power is readily available. As fossil fuel energy costs climb, production experience and economies of scale reduce prices, and technological advances increase the efficiency of solar cells, this may not be true in the relatively near future. Many installations at this time are motivated by tax incentives and green sensibilities.
