conceive of originate greens in your backyard under a solar panel and then juicing them in a blender power by the same energy . A novel University of Alberta project is working to make that a reality .
By growing spinach plant under different solar panels , two U of A investigator are measuring how the mental process affects both plant growth and the electric output of the panel .
have intercourse as agrivoltaics , the fairly new sustainable pattern integrates solar board with crop , making simultaneous employment of land for both food and energy production .
Agrivoltaics has the potential to address several constrict issues around sustainability , says Guillermo Hernandez Ramirez , an associate professor and soil scientist in the Faculty of Agricultural , Life & Environmental Sciences .
“ It brings together major challenges we have out front of us : the vigor transition to renewable energy sources and the questions of flow the reality and addressing issues of climate action , ” he says .
Agrivoltaics has other benefits besides double demesne use and food certificate ; it could also reduce nursery gas emissions and make more efficient use of water .
And it ’s scalable to service both rural and especially urban Department of Agriculture by cause role of backyards and city unripe outer space to develop intellectual nourishment and yield electricity , he note .
That , in turn , avail citizenry see sustainability as a way of life , Hernandez Ramirez believes .
“ It brings this estimation of connection . By having agrivoltaics in urban configurations , masses can experience what it ’s wish to be able to produce both food and electrical energy . ”
“ We ca n’t source all the food and energy we need from agrivoltaics , but it hit a share , and people can have that context . It build up a sensation of like about where these things are coming from . ”
Win - win for industrial plant and solar panelsThe U of A pilot projection is an initial step in exploring the possible benefit of agrivoltaics , state research intern Camila Quiroz , who is guide the experiment .
“ The field has n’t been research much , but more cognition will be necessary in the cheeseparing future for us to continue hold up in the world , ” she say .
In the 25 - day project , conducted in a maturation sleeping room , the investigator compared the ontogenesis of spinach industrial plant under three different conditions — with no solar instrument panel or shaded by either a thin or a thick panel — and also measured how much electrical energy can be harvest from each character of instrument panel .
Agrivoltaics tend to have benefits for both plants and panels , she notes .
“ Solar panels have better output with lower temperatures , so by place the plants under the panels , it creates a cool down effect that help the panels be more efficient . ”
In go , leafy flora like Spinacia oleracea and lettuce , along with succulent green goods like berries , corn , onion , tomatoes , and grape , call for specter to thrive — which the solar venire in this experiment provide .
former results show promiseThe month - long experiment showed promising results , the researchers notice .
Under the solar panels , the spinach plants consumed up to 17 percent less water , and though their emergence was dull than without the panels , the plants ’ overall wellness remained high as they neared harvest time exercising weight .
“ It evidence that using agrivoltaics is not detrimental to implant health , ” she notes .
The solar panels also return a office yield of 10 watts , enough to power electronic devices such as peregrine earpiece , tablets , light-emitting diode lamps , or lowly appliances .
“ This undertaking is a step ahead in show that as we harvest solar energy for exercise in our family , for case , we could also be develop nutritive food at the same time , ” says Hernandez Ramirez .
Once the projection data are full analyzed , the answer will be published in a scientific paper , and Quiroz also plans to produce a how - to pass for the public “ so people can start up practice some of these things . ”
Hernandez Ramirez also hopes to share the guide with the City of Edmonton as a useful example of how agrivoltaics could be optimized for the city ’s conditions condition .
“ This is an lesson of a very good task that would help the city in its quest to do more sustainable maturation . ”
The next steps are to secure research funding to further test agrivoltaics with other works such as berries and more vegetables , explore unlike angles and arrangements of solar panels , and test them in outdoor conditions like rain , he tote up .
“ Agrivoltaics is a whole new playing area of research and an option we want to keep explore and find way to enforce because it ’s a win - win for society and for food and land industries . ”
