Putting science
at the heart of development
Definitions
Below is a directory of terms used in discussions about solar power. Most of the terms have been reproduced from the International Energy Agency, the UN Environment Programme or the US Department of Energy.
Technologies to harness solar power as a path to low-carbon energy are developing at breakneck speed. How can developing countries best make use of them to benefit the millions of rural poor who still live without electricity?
G
Grid-connected solar system
A solar system that is connected to the central electrical grid. This system does not require batteries and is mainly used to offset the energy supplied by the mains electricity grid, or to supply power to the grid. Also called on-grid system or grid-interactive system.
Grid parity
Occurs when the cost of electricity from a renewable energy source is equal to the cost of grid electricity at the point of connection.
