Agrivoltaics (solar sharing) is an innovative approach that combines agricultural production with renewable energy generation. To successfully implement such projects in Japan, it's crucial to have a precise understanding of the Agricultural Land Act, which safeguards the nation's agricultural foundation, along with various other laws and guidelines.Chapter 1: Overview of Key Laws and Regulations Governing Agrivoltaics1-1. The Agricultural Land Act and MAFF Notifications/GuidelinesThe installation of agrivoltaics facilities on farmland is permitted under a special provision of the Agricultural Land Act concerning temporary land conversion.Special Provision for Temporary Agricultural Land Conversion Permits Farmland is, in principle, designated solely for agricultural purposes. However, temporary conversion for other uses may be permitted under specific conditions. Agrivoltaics facilities fall under this temporary conversion permit."Regarding the Handling of Agricultural Land Conversion Permits for the Installation of Agrivoltaics Facilities" (2013 Notification): This notification officially recognized the installation of agrivoltaics and established the following core principles:Support structures must be temporary and removable at any time.Cultivation must continue on the farmland beneath the panels, ensuring proper agricultural activity.The installation must not hinder farming on adjacent agricultural land."Regarding Agrivoltaics Facilities" (2021 Revision): This revision extended permit durations and relaxed certain conditions for specific types of farmland.Extended Permit Duration: The permit period was extended from the traditional 3 years to a maximum of 10 years, reducing the administrative burden on project operators.Relaxed Conditions: Especially for "degraded farmland," a special exemption was introduced, waiving the 80% yield maintenance requirement (detailed below). This aims to promote the effective utilization of idle or abandoned farmland.Clarification of Agrivoltaics in the Amended Agricultural Land Act (April 2024): This amendment formally established guidelines for the appropriate use of agrivoltaics, strengthening measures against improper practices. This aims to support legitimate projects and enhance the overall quality of the market. While this amendment might lead to a perception of stricter reviews, it's generally seen as a positive step towards ensuring genuinely agriculture-compatible projects and increasing market transparency and trustworthiness in the long run.Details of the Continuous Farming Requirement (80% Yield Maintenance Rule) One of the most critical rules for agrivoltaics in Japan is the requirement that crop yields beneath the panels must remain at least 80% of the normal average yield for that land without the panels. This ensures that the agrivoltaics installation does not significantly hinder agricultural production.Application and Purpose of the 80% Rule: This rule aims to minimize the impact of shading from solar panels on agriculture and to maintain the productivity of farmland.Conditions for Exemption and Obligation for Continued Farming on Degraded Farmland:When land is certified as degraded farmland (i.e., land in a state similar to abandoned cultivated land, where the Agricultural Committee has confirmed through on-site inspection that "continued farming is difficult"), the 80% yield maintenance requirement may be waived.However, even with this exemption, the obligation to conduct continuous farming activities on the land remains.On-site Utilization and Challenges: While some examples of this special provision's use exist, its application remains limited nationwide. A primary challenge is that rehabilitating degraded farmland often incurs significant effort and cost. Even with the 80% yield requirement waived, establishing viable agricultural operations can be difficult, hindering the wider adoption of this exemption. The certification process itself can be complex, varying by municipality and requiring extensive documentation (e.g., aerial photos, farming history) and on-site inspections, which can be time-consuming.1-2. Other Relevant Laws and RegulationsBeyond the Agricultural Land Act, agrivoltaics projects must comply with various other laws and ordinances.Electricity Business Act: This act governs requirements for electricity business registration, installation of electrical facilities, and maintenance permits for power generation.Building Standards Act: If the agrivoltaics structure is classified as a building (based on height, foundation, area, etc.), a building confirmation application may be required.Fire Service Act: This act outlines regulations related to fire safety. For larger installations, notification to the fire department may be necessary.Landscape Act and Local Ordinances: Some local governments may have ordinances to preserve regional landscapes, which could regulate panel color, height, and layout.Environmental Assessment Act: For projects exceeding a certain scale, an Environmental Impact Assessment (EIA) may be mandatory.Feed-in Tariff (FIT) / Feed-in Premium (FIP) Related Regulations:FIT/FIP Framework: These systems are crucial for promoting renewable energy in Japan and significantly impact the profitability of agrivoltaics. Since 2022, large new projects have been transitioning from FIT (fixed price) to FIP (market price + premium).Incentives for Agrivoltaics: Due to their potential for community contribution, agrivoltaics projects sometimes receive policy incentives, such as relaxed capacity limits for specific categories or eased requirements for power supply during disasters. The transition to FIP introduces market price fluctuation risks, demanding more meticulous business planning and risk management for new projects.
