The technique was originally conceived by Adolf Goetzberger and Armin Zastrow in 1981, and the word agrivoltaic was coined in 2011. Today, agrivoltaic practices and relevant laws vary from one country to another. In Europe and Asia, where the concept was first pioneered, the term agrivoltaics is applied to dedicated dual-use technology, generally, a system of mounts or cables to raise the solar array some five meters above the ground in order to allow the land to be accessed by farm machinery, or a system where solar paneling is installed on the roofs of greenhouses. The shade produced by such a system can reduce the production of some crops, but such losses may be offset by the energy produced.
