Solar Energy Modelling and Proposed Crops for Different Types of Agrivoltaics Systems
Canada can radically reduce greenhouse gas (GHG) emissions by aggressively deploying agrivoltaics and reach its goal of cutting emissions by increasing the non-emitting share of electricity generation to 90% by 2030. To help reach this goal, this study evaluated the potential energy production for vertical bi-facial solar photovoltaic arrays as well as the solar irradiation reaching the ground with three different spacings (5m, 15m and 45m) and three different Canadian farming locations (London, Calgary and Winnipeg) using irradiance modeling with Ladybug tools plug-ins for Grasshopper and Honeybee . The crops currently grown in each region were identified and their sunlight requirements were analyzed. Based on the amount of solar radiation reaching the ground surface and the solar requirements of the crops, inter-row spacings that were suitable for agrivoltaic applications for the three locations were identified. Next the land acreage of a select few crops, which were proven to be satisfactory for agrivoltaic systems, were identified for each province and their electrical energy potential was ascertained using System Advisor Model. The results indicate that more than 84% of the total national electricity requirements can be met by employing agrivoltaics on agricultural land where these crops are cultivated in the three provinces.
Highlights[edit | edit source]
- Agrivoltiac energy production for vertical bi-facial PV and solar irradiation reaching the ground
- Spacings (5m, 15m and 45m) and Canadian farming locations (London, Calgary and Winnipeg)
- Irradiance modeling with Ladybug tools plug-ins for Grasshopper and Honeybee.
- Crops currently grown in each region identified and their sunlight requirements were analyzed
- Suitable agrivoltaics + land acreage of select crops quantified = 84% Canada’s electricity needs
