An independent power producer (IPP) or non-utility generator (NUG) is an entity that is not a public utility, but owns facilities that generate electric power for sale to utilities and end users. NUGs may be privately-held facilities, corporations, cooperatives such as rural solar or wind energy producers, or non-energy industrial. For most IPPs, particularly in the , a or provides a long-term price guarantee.

The power (in watts) of the solar panel is the voltage (in volts) multiplied by the current (in amperes), and depends both on the amount of light and on the electrical load connected to the panel. Each module is rated by its output power under standard test conditions and hence the on field output power might vary. Solar panel conversion efficiency, typically in the 20% range, is reduced by the accumulation of dust, grime, pollen, and other particulates on the solar panels, collectively referred to as. Early developmentsIn 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist.
