Agrivoltaics: solar pamusoro pezvirimwa

Solar farms inofanirwa nyika, uye nzvimbo yakanaka yezuva, yakavhurika, yakapfava uye ine mvura, ndeyenzvimbo dzese dzekurima. Izvi zvinokonzera kusangana kwezvinhu zvakasiyana-siyana zvekudya nesimba. Agrivoltaics (akanziwo agrophotovoltaics kana solar kugovera) edza kubvisa izvi: mapaneli pazvigaro zvakakura kana mumisoro yakaenzana, nemiti kana kuchera pasi pevo uye pakati pavo.

Kuongorora kwakachena: **Agrivoltaics yakaratidza kusimudzira huwandu hwezvigadzirwa zvemumunda, kazhinji kacho ne50 kusvika 80%, asi inoramba ichipa mamwe masimba emagetsi kana zvichienzaniswa nenzvimbo yezuva, uye inowanzopa zvimwe zvinovaka muviri kana zvichienzaniswa nenzvimbo dzakavhurika, uye inodhura kupfuura chero imwe. Inokunda apo kutonhora kunobatsira kugadzira michero, apo nyika ine kukosha kwakanyanya kuti iite, kana apo mitemo inoda kuti kurima kuenderera mberi. **

Greenhouses nezuva dzimba uye mapaneli pamusoro orchards, vineyards uye berries (apo vanogona kuchinja hazel nets uye plastiki zvivharo) kugara pakati pezvimwe izvi.

Maitiro ekushanda

Ruvara runowanzoshandiswa, asi harubatsiri. Mazuva ezuva pamunda ane mari yakazvimiririra: 1000 kusvika ku2000 kWh pamita imwe chete yemugwagwa gore rimwe munharaunda dzese dzekurima. Panels intercept chikamu cheizvo uye crop anowana zvimwe. Chikonzero ndechekuti michero yakawanda haigone kushandisa mvura yakakwana yezuva. Photosynthesis muzuva rinokwira nezuva uyezve inovhara panzvimbo yekusanganiswa kwezuva; pamusoro pezvo, kuwedzera kwezuva kunowedzera tembiricha uye kumanikidzwa kwemvura kupfuura kukura. Shade-tolerant michero senge maruva vegetables, clover grass, akawanda mafruits uye berries saturate nguva pfupi yadarika uye vanorasikirwa nepakati pezuva kana chikamu chezuva chichitora (Fraunhofer ISE, 2024). Sun-hunger michero semupunga kana wheat munguva yakachena gore kushaya zvakawanda.

The land equivalent ratio. The standard way to judge a shared field is LER = Y_crop,shared / Y_crop,alone + Y_power,shared / Y_power,alone. Mumashoko akajeka: wedzera chikamu chemupunga waunowana nechibage chako kuchikamu chemagetsi auchawana kubva pazvicherwa zvako. LER ye1.0 inoti kugoverana hakuite zvakanaka kupfuura kuparadzira nyika kuita kaviri; 1.6 inoti imwe hectare inopihwa inoita basa re1.6 dzakasiyana. Modeling naDupraz uye vatsigiri vakafungidzira 1.35 kusvika 1.73 yezviyo nezuva mukumadokero kweFrance (Dupraz et al., 2011).

Shade inoita kuti microclimate igadzikane. Pamusoro pezvimbadzo, mvura inopisa uye inotonhora inogara ichitonhora munguva yezhizha neyemasikati, uye kana kusina mvura, michero inogona kuita zvakanaka kupfuura mune yakavhurika nzvimbo (Barron-Gafford et al., 2019; Fraunhofer ISE, 2019). Paneleswo anowana: humidifier pamusoro pezvirimwa inoita kuti zvive zvakachena kupfuura paneles pamusoro pevhu rakasviba.

Electricity per hectare falls. Rows must be spaced for light and machines, so fewer panels fit. At Heggelbach the installed capacity per hectare was about 25% lower than a conventional solar farm, but two-sided panels high off the ground caught extra reflected light, so the electricity per hectare was 83% of a normal farm’s.

Zvirambidzo

Theoretical. Sunlight inoshandiswa pamwe chete: pazuva rimwe nerimwe rine kilowatt-hour yezuva, magetsi anotora, asi mbeu haiwanikwe. Agrivoltaics inogona chete kukunda kushandiswa kwenzvimbo yakazvimirira kana mbewu yakanga isina kushandisa zvese zvinobuda (kana kuti yaive nengozi). Panzvimbo dzakakwirira dzepaneti, michero miviri inodzikira: imwe chete yezuva rine simba remagetsi rinobata nzvimbo yakawanda kupfuura chero chikafu chinogona kuchengeta.

See-through solar: kugovera magetsi nechiedza

Paneles anozivikanwa anoparadzira magetsi nenzvimbo: imwe nzvimbo yemunda iri pasi pechiedza, imwe iri pasi pezuva. A newer family of panels tries to share it by color instead. Zvirwere zvinokura pazuva rinoonekwa, kubva kuvioleti pa400 nanometer kusvika kumagumo emaruva pa700, iyo band scientists vanoitaura sephotosynthetically active radiation. Ruvara rwemaruva runovapa simba rekuzvigadzira zvakachipa kune chero chinhu chinoita sezuva, asi magetsi eblue neyechiedza chekutsva zvinoshandiswawo (McCree, 1971). Nekuti 43% yesimba rezuva rinobva pasi pevhu rinosvika mubhandi iri; 5% iri ultraviolet uye 52% iri infrared, izvo zvicherwa hazvigone kushandisa kukura (izvi zvinokonzera kuti zviite sezvatinoita nemvura).

Mamwe matanho mana ari kuedza, mumigwagwa miviri:

Semi-inoratidzika zvakanaka mapaneli ane zvakasiyana-siyana zvigunwe (zvekutengesa). Macells esilicon anoiswa pamwechete pane girazi kuti mhepo iite makumbo; muGelsdorf apple orchard mune tafura iri pamusoro, anoshandisa aya. Kutengesa kuri nyore: magetsi anokwira pamwe chete nenzvimbo yakapfuura pasina ma cell (Traverse et al., 2017). In a comparison of four commercial greenhouse types in Europe, the light inside over a year fell on average by 0.8% for each extra 1% of roof covered with panels, and a north-south layout and a checkerboard pattern spread the light more evenly (Cossu et al., 2018).
Kunamatira, luminescent mapaneti (madiki ekutengesa zvivakwa). A dye mugirazi inotora chikamu cheblue uye green mwanga uye inotungamira kune strips yesilicon cells; iyo yakati wandei inopinda, iyo inovimbisa girazi remagenta glow. Muzvidzidzo zveUniversity of California, Santa Cruz, nechiremba wezvekutengesa, matomatisi ari pasi peaya mapaneli akaratidza shanduko shoma mukuwana uye kuoma kwezvirimwa zvavo uye anoshandisa zvishoma nezvishoma zvishoma (Loik et al., 2017). Mugadziri, Soliculture, inoti yakatanga kutengeswa kwekutanga luminescent solar concentrator muna 2012 uye yakaisa mapaneli ayo muzvivakwa zvemagreenhouses muUnited States neCanada (Soliculture).
Semi-inoratidzika organic solar cells (laboratory uye pilot). Thin carbon-based mafilms anogona kugadziriswa kuti aone zvakanyanya grey uye nepakati pe infrared light. Vatsvakurudzi kuNorth Carolina State University vakakura gomo rezuva rered pasi pezvishongedzo zvakagadzirwa kubva kune matatu akasiyana organic cell zvinhu uye havana kuwana chero kukosha kwekusiyana muhuwandu hwemafuta kana chlorophyll (Ravishankar et al., 2021).

Tinofanira kuita sei

Agronomist kana crop physiologist kuti vaite sarudzo dzezvirimwa, vagadzirise ma plots akapetwa kaviri uye vaongorore kugadzirwa kwezvinhu uye mhando.
PV system designer anozivikanwa ne bifacial uye tracking systems uye shade modelling.
Structural engineer yepakati, yakareba-span zvivakwa pasi pemhepo uye snow loads.
Mumwe mugari ane nzvimbo, michina uye rusununguko rwekuzvipira kwemakore mazhinji.
Hydrologist yemvura yekugovera, soil moisture uye irrigation savings.
Agricultural economist and land-use lawyer kuti vaone bhizinesi rezviri kuitika uye mitemo.

Une pfungwa yakanaka?

Ndokusaka iwe uine yakachipa kugadzira, chikafu system kuti anofarira shade, kana smarter nzira yekufambisa mapaneli kuburikidza zuva. Vamwe vatungamiri ve Local Solar System Foundation vanogona kunge vane vanhu vanoita kuti vaone kuti pane chikonzero chekusimudzira simba. Kuti iite, pfungwa inofanira kunge iri kushanda, real-life model iyo yakafanana neyakagadzirwa nevanhu, yakaiswa pachinhu, asi isina kutaurwa. Ipfungwa dzepapepa dziri kutarisirwawo: kana physics uye mazita ari nyore, tinogona kuzviburitsa pano pawebsite. Kusimudzira mari pasina kushanda kwemufananidzo kunogona kunge kuri nyore, asi hatigone kuvimbisa mari, mari yekudzoka kana kuvhura.

Kuzvimiririra kwemagetsi ezuva mumunda wechibage, kuongororwa kuri nyore uye kunokosha semufananidzo wekushanda ndeye kuongorora kupera kwegore rekugadzira kwechibage chiri pasi pepaneti pamwe nechibage chisina paneti, nekushandisa masenzori ekuona mhepo, kuongorora huwandu hwemafuta anogadzirwa nechibage uye kuongorora huwandu hwemagetsi anopihwa. Izvi zvinopa ruzivo rwekutanga nezvekuenzaniswa kwenzvimbo dzese dzakaenzana. Kutumira kuburikidza ne contribution form, uye ona sei ichienzaniswa nevamwe mazano pa idea radar. Sibling nzira: floating solar inoshandisa madziva nzvimbo kwete maindasitiri, uye PV-thermal Roofs kuita Roofs kuita zviviri mabasa.
