The concept of agrivoltaics dates back to the early 1980s when German physicist Adolf Goetzberger first proposed combining agriculture and solar energy production to address land scarcity, food security, and increasing energy demand.
Over the years, agrivoltaics has evolved into a promising solution that addresses various global challenges while offering significant benefits to agriculture, such as increased land use efficiency and water savings.

The Origins and Evolution of Agrivoltaics from Adolf Goetzberger’s Vision
The origins of agrivoltaics can be traced back to the early 1980s when concerns about land scarcity, food security, and increasing energy demand started to gain prominence. At the time, solar energy emerged as a viable alternative to conventional fossil fuels. As a result, scientists were exploring innovative ways to integrate renewable energy production with traditional land use practices. Adolf Goetzberger, a German physicist and solar energy pioneer, was among the first to propose combining agriculture with solar energy generation, thus giving birth to agrivoltaics in its 1981 paper published in the International Journal of Solar Energy with Armin Zastrow.
Agrivoltaics, also known as agrophotovoltaics or solar sharing, was conceived as a solution to the dual challenge of producing sufficient food and energy for a rapidly growing global population while preserving the planet’s limited resources. Goetzberger envisioned that integrating solar panels with agricultural land could lead to better land utilization, increased efficiency in energy production, and minimal disruption to agricultural activities. As a result, research and experimentation in agrivoltaics began to gain traction, leading to the development of various configurations and approaches that maximized the benefits of combining food production with renewable energy generation. Over the years, agrivoltaics has evolved into a promising solution that addresses the pressing issues of land scarcity, food security, and climate change, with its roots firmly grounded in the visionary work of Adolf Goetzberger.
According to Adolf Goetzberger’s work, several essential criteria must be considered before classifying a system as agrivoltaics:
- There must be a seamless integration of solar energy production with agricultural activities, ensuring neither is compromised.
- The configuration should optimize land use efficiency by maximizing food production and energy generation within the same area.
- The system should prioritize sustainability, minimizing environmental impacts, such as soil degradation, water consumption, and biodiversity loss.
- The agrivoltaic system should demonstrate a synergistic effect between agriculture and solar energy production, providing benefits beyond each component’s outputs.
