infrared radiation

Electromagnetic radiation whose wavelengths lie in the range from 0.75 micrometer to 1000 micrometers.

Light that shines onto the surface of a solar cell or module.

A graphical presentation of the current versus the voltage from a photovoltaic device as the load is increased from the short circuit (no load) condition to the open circuit (maximum voltage) condition. Typically measured at 1000 watts per square meter of solar insolation at a specific cell temperature. The shape of the curve characterizes cell […]

A PV system that includes other sources of electricity generation, such as wind or fossil fuel generators.

See `Grid-connected (PV system).’

A PV system in which the PV array acts like a central generating plant, supplying power to the grid.

See `Electrical grid.’

The boundaries where crystallites in a multicrystalline material meet.

Clear materials (such as glass or plastic) that allow sunlight to pass into solar collectors and solar buildings, trapping heat inside.

One billion watts. One million kilowatts. One thousand megawatts.
