Agrovoltaics, sometimes called agrophotovoltaics, is a combination of agriculture and solar energy.

This is a method in which solar panels are installed above or between crops on a farm plot to maximise the performance of both systems.

\

The main advantages of agrovoltaics include:

Agrovoltaics is a constantly researching and innovating field that is evolving to bring even greater benefits to agriculture and energy.

Energy efficiency
Solar panels can provide clean energy for agricultural operations and reduce dependence on fossil fuels.

Sustainability
This method can contribute to environmental protection by reducing greenhouse gas emissions and increasing the sustainability of farming practices.

Water savings
Shading crops with solar panels can reduce evaporation and improve irrigation efficiency.

Increased yield
Some crops can have higher yields when grown under solar panels, as shading can help protect them from extreme weather such as heavy rain or sunlight.

Income diversification
Farmers can earn income from the sale of solar energy, which increases financial stability and reduces dependence on a single source of income.

Which crops are suitable for growing under PV and why?

Some crops are more suitable for growing under agro-pilot systems than others. The choice of crops depends on several factors, such as the climatic conditions, the level of shading provided by the solar panels and the light requirements of each crop.

Crop rotation: Cereals, legumes, root crops or vegetables.

Pasture and forage: Grasses and other forage crops for livestock. Shading can reduce heat stress and improve forage growth.

Vegetables with lower light requirements: Spinach, lettuce, radishes or cabbage.

Stress-tolerant crops: Cacti, agaves or some types of alfalfa.

Crops with a long growing season: Fruit trees or vines.

Example studies on the benefits of growing crops under Agrofotovoltaics

Agrophotovoltaic systems: applications, challenges, and opportunities. A review

One study that confirms the benefits of growing crops under PV is “Agrophotovoltaic systems: applications, challenges, and opportunities. A review” by Barron-Gafford et al. (2019), published in the journal “Agronomy for Sustainable Development”. This study analyses the benefits and challenges associated with agrivoltaics and provides evidence of its positive impact on agricultural production and energy efficiency.

The authors of the study evaluate various aspects of agrivoltaic systems, including the performance of solar panels, impact on water management, soil quality and microclimate, and explore different application scenarios such as crop, livestock and aquaculture.

Some of the main findings of the study include:

  • Agrivoltaics can lead to higher overall land yields than traditional farming or solar systems separately.
  • Solar panels can provide shading and protection for crops, which can improve their growth and reduce heat stress.
  • Agrivoltaic systems can reduce evaporation and improve irrigation efficiency, which is important in areas with limited water resources.
  • Joint management of agricultural and solar infrastructure can lead to cost savings and efficiency gains.
  • Agrivoltaics can contribute to the sustainability of agriculture and energy and reduce greenhouse gas emissions.

This study confirms that growing crops under PV can be very profitable if the specific needs of the crop, location and systems are properly considered.

Combining solar photovoltaic panels and food crops for optimising land use: Towards new agrivoltaic schemes

Another example of a study that explores the benefits of growing crops under PV is “Combining solar photovoltaic panels and food crops for optimising land use: Towards new agrivoltaic schemes” by Dinesh et al. (2016), published in the journal Renewable Energy. This study focuses on analysing the potential of combining solar panels and agricultural crops to optimise land use and increase efficiency.

Some of the main findings of the study include:

  • The combination of solar panels and agricultural crops can improve land use, which is important in areas with limited space.
  • Optimizing the design of agrivoltaic systems, such as panel placement and orientation, can increase energy efficiency and agricultural production.
  • The study explores various options for combining solar panels and crops, including vertical farming, horticulture and aquatic crops.
  • The authors identify potential challenges and barriers to the implementation of agrivoltaic systems, such as costs, technical constraints and legislation.

This study provides further evidence of the benefits of growing crops under PV and highlights the need for further research and innovation to develop new agrivoltaic solutions.
