Oregon studies solar panel impacts on pasture and livestock growth

In a recent meeting of the Oregon Senate Committee on Energy and Environment, discussions centered on the promising intersection of agriculture and renewable energy through agrivoltaics. This innovative approach combines solar energy production with agricultural practices, aiming to optimize land use while addressing climate change challenges.

Dr. Higgins presented findings from ongoing studies that explore the impact of solar panels on pasture production. The research indicates that while forage production in solar pastures is reduced by about 30% due to shading, the overall health and growth of livestock, particularly lambs, remain unaffected. This is attributed to the sheltering effect of the panels, which provide protection from extreme weather conditions, allowing animals to conserve energy and thrive.

One significant advantage highlighted was the ability of solar pastures to retain soil moisture, extending grazing periods by up to three weeks during dry summer months. However, concerns were raised about localized water accumulation at the edges of the panels, which could negatively impact plant growth, particularly in Oregon's rainy climate.

The committee also discussed the broader implications of agrivoltaics for climate resilience. Well-designed systems could enhance the sustainability of pasture-based livestock operations, making them a viable strategy for adapting to increasing temperatures and erratic weather patterns.

Senator Walden emphasized the need for Oregon to learn from other states that have advanced agrivoltaic practices. He suggested that compiling best practices from across the nation could provide valuable insights for Oregon's task force, which is exploring regulatory frameworks for agrivoltaics.

As the state moves forward, the integration of solar energy with agricultural practices could not only support local farmers but also contribute to Oregon's goals for renewable energy and climate adaptation. The committee's discussions reflect a growing recognition of the potential benefits of agrivoltaics for both the environment and the agricultural community.
