Electrical sheep in solar power conjunction wed Australian farmers for clean energy
In an innovative blend of renewable energy and agriculture, a growing number of farmers and solar companies are discovering the benefits of solar grazing. This unique partnership is transforming barren land under solar panels into thriving grazing grounds, all while reducing costs and promoting sustainability.
Previously, some farmers from New South Wales claimed that sheep grazing under solar farms resulted in an increase in wool quality and quantity [1]. Iberdrola, a renewable energy company in Portugal, began grazing 300 sheep on its photovoltaic farms in 2023, setting a precedent for the integration of agriculture and renewable energy [2].
For farmers, this partnership offers a steady income stream. They can lease their land to solar companies, allowing them to continue agricultural activities like grazing sheep. Not only does this provide a source of income, but some farmers have reported improved wool quality and quantity [2]. In addition, some solar farms offer reduced farm power costs, as the energy generated can be used for irrigation and other operations [3].
Meanwhile, solar companies reap significant benefits as well. By using sheep for vegetation management, they can save on maintenance costs, such as mowing and herbicide usage [2]. This not only reduces carbon emissions but also lowers fire risks, as controlled undergrowth can help prevent wildfires [2][4].
The integration of solar farming and agriculture is a prime example of agrivoltaics, where land is used simultaneously for solar energy production and agriculture, enhancing land efficiency and environmental outcomes such as moisture retention and shade provision for plants and animals [5].
A project in the UK plans to use 4,000 sheep on its 1,600-hectare solar farm, which could save $6.71 million (£5 million) in mowing costs over 40 years [2]. The United States has also seen solar power farming setups as a business-savvy move, with farmers establishing a multi-billion-dollar industry out of 'solar grazing' [6].
Eric Nordberg, a researcher at the University of New England, stated that solar grazing setups are beneficial for farmers who don't want to lose their grazing landscape to a big solar company [7]. Solar grazing, therefore, creates a productive synergy: solar farms gain sustainable, cost-effective land management while farmers benefit economically and agriculturally without losing land control or agricultural productivity.

- The intersection between science and innovation has led to the concept of renewable-energy agriculture, where farmers and solar companies are cooperating to practice solar grazing.
- In the realm of renewable-energy industry, solar companies are embracing robotics for vegetation management during solar grazing, thereby cutting down maintenance costs.
- The financial benefits extend to home-and-garden lifestyle, as some solar farms offer reduced energy costs for farmers, which can be utilized for various operations like irrigation.
- Sustainable-living enthusiasts are taking note of the symbiotic relationship between renewable energy and agriculture through solar grazing, as it promotes a more eco-friendly energy production.
- The integration of solar panels with home-and-garden landscapes, also known as agrivoltaics, is being explored as a means of increasing land efficiency and fostering a more sustainable way of life.
