Quick Answer
Agrivoltaic systems are feasible in developed urban areas, offering co-benefits such as increased crop yields and reduced energy costs. Urban agrivoltaics can utilize rooftops, community gardens, and vacant lots for solar panels and crops. However, high upfront costs and permitting challenges remain significant hurdles.
Urban Rooftop Opportunities
Urban rooftops offer a prime location for agrivoltaic systems, with over 70% of rooftops in urban areas being underutilized. By integrating solar panels and crops, cities can reduce energy costs and increase local food production. For example, the Green Roof in Chicago’s City Hall features over 20,000 square feet of solar panels and a thriving green roof garden, demonstrating the potential of urban agrivoltaics.
Crop Selection and Yield Enhancement
When selecting crops for urban agrivoltaic systems, it’s essential to consider plants that can thrive in partial shade and have shorter growth cycles. Crops like leafy greens, herbs, and strawberries are well-suited for urban agrivoltaics and can yield up to 3-4 harvests per year. By using techniques like trellising and pruning, growers can optimize crop yields and minimize shade impacts on solar panels.
Permitting and Policy Frameworks
Implementing agrivoltaic systems in urban areas requires a supportive policy framework and streamlined permitting processes. Cities like New York and Los Angeles have established incentives and regulations to encourage urban agrivoltaics, including tax credits and streamlined permitting procedures. Cities can also learn from successful pilot projects and case studies to develop effective policies and guidelines for urban agrivoltaic development.
