ImiGangatho yeHlabathi iNxulumana neZenzo zeGrassroots: Iimpompa zeSolar ze-DC eziSubmersible zichaza kwakhona uBulungisa baMandla

I-Nairobi/Geneva, ngo-Okthobha wama-20, ngo-2023 - Njengoko iingcali ezivela kwi-International Electrotechnical Commission (IEC) zagqibezela amalungiselelo obugcisa be-DC Solar Submersible Pump Technical Specification eSwitzerland, amawaka eekhilomitha kude e-Kenya's Kajiado County, umlimi oneminyaka engama-45 ubudala uMargaret Mutoni elawula ukude i-solar corn fields impompoza ngefowuni yakhe. Lo mboniso ubonisa ngokucacileyo indlela ukumiselwa kwemigangatho yamandla amatsha ehlabathi kulungelelaniswa ngayo nezinto ezintsha ezisemhlabeni.

Umgangatho njengoMda woBomi: Ngaphaya kweeParameters zobuGcisa kuKhuseleko lokuPhila

Kutshintsho lwamandla ehlabathi, iimpompo zesolar ze-DC ezintyumpantyumpeka zibaluleke kakhulu kunkcenkceshelo lwezolimo kwimimandla enqongopheleyo yamandla efana ne-Afrika kunye ne-Asia-mpuma ye-Asiya, ezixatyiswa ngesakhono sazo esingekho kwigridi kunye neendleko zolondolozo oluphantsi. Nangona kunjalo ukukhula okukhawulezayo kweshishini kufihla intsilelo yemigangatho: ukuhambelana kwamandla ombane kuyahluka nge-30% kubo bonke abavelisi, ukulinganiswa kokuthintela amanzi akuhambelani, kwaye "iplagi engahambelaniyo" yenzekile. Idatha ye-UNIDO ibonisa i-35% yezinga lokungaphumeleli kwi-off-grid photovoltaic impompo kumazwe asakhasayo, kunye nesiqingatha seeprojekthi ezingasebenzi kakuhle kwiminyaka emibini.

"Ukumisela okusemgangathweni akukhona nje ngamaxwebhu obugcisa; sisiqinisekiso sokhuseleko olusisiseko sokuphila, "ugxininisa u-Ashok Gupta, uMlawuli Jikelele weKomishoni yamazwe ngamazwe yokunkcenkceshela kunye nokukhutshwa kwamanzi (ICID). Emva kweminyaka emithathu yothethathethwano, idrafti yomgangatho we-IEC idibanisa "ubungakanani bobuntu" kwiimfuno zobugcisa: ukugunyazisa ujongano lokusebenza lwe-night-reflective kubasebenzisi abangafundanga, efuna i-12V-24V voltage adaptability ukuze ihambelane ne-African generator generator backups, kunye nokwazisa "i-dynamic light intensity adaptive algorithm". Umphandi weZiko leSizwe loMgangatho waseTshayina u-Li Wei uqaphela ukuba uyilo lubandakanya "amagatya aguquguqukayo," ukugcina umda we-20% wokulungelelaniswa kwengingqi phantsi kweziqinisekiso zokhuseleko ezingundoqo ukulinganisa ukuhambelana kwehlabathi kunye nokutsha kwendawo.

Ukunyuka kweTshayina: Ukusuka kuBathathi abasemgangathweni ukuya kubaPhathi boLawulo

Iinjineli e-Shenzhen's BYD ziguqulela imimiselo eyidrafti yomgangatho kwizisombululo ezisebenzayo. Inkqubo yabo yempompo ehlakaniphile, exhotyiswe nge-algorithm yokulandelela i-solar inverter-integrated, i-auto-adjusts water output based on cloud cover, iphumelele i-30% yokonga amanzi kwiimodeli zendabuko. Iingxowa zeplastiki ezisetyenzisiweyo zinciphisa iindleko nge-40% ngelixa zihlangabezana neemfuno ze-carbon footprint ye-lifecycle. EKenya, obu bugcisa buye bakhulisa isivuno sikaMargaret sombona ngeetoni ezisisi-2,3 ngehektare nganye baza bawuphinda kabini umvuzo wonyaka wentsapho yakhe.

Ngaphambili, besiziqhelanisa nemigangatho yaseNtshona; ngoku itekhnoloji yaseTshayina iphinda ibhale imithetho, utshilo uMlawuli waMandla oMtsha weBYD uChen Ming. Inkampani ibe negalelo kwizindululo zobugcisa ze-IEC ezisixhenxe, kunye ne "Dynamic Light Intensity Adaptive Power Regulation" eyamkelwe njengegatya elisisiseko. Le mpumelelo ifumene i-200 yezigidi zeedola kwii-odolo zase-Afrika kwaye yabangela uMbutho we-Afrika eseMpuma (EAC) ukuba iquke imigangatho yaseTshayina kwizikhokelo zokuthengwa kwempahla yengingqi.

Impembelelo yeNtlalo: Itekhnoloji njengeCatalyst yoBulungisa ngokweSini

Uyilo lomgangatho "olugxile eluntwini" luhlengahlengisa iintshukumo zesini. ETanzania, apho i-80% yokuqokelela amanzi asemaphandleni iwela kwabasetyhini, imithetho emitsha igunyazisa i-icon-based interfaces kunye nokukhuthaza uqeqesho lokugcinwa koluntu. Uphononongo lweBhanki yeHlabathi lubonisa iiprojekthi zezixhobo ezisemgangathweni zonyusa ukuthatha inxaxheba kwabasetyhini ekusebenzeni/ugcino lusuka kwi-12% ukuya kwi-68% kwaye lunciphisa iindleko zamanzi kuluntu ngama-30%.

“Xa imigangatho yobugcisa ithatha indawo yombhalo ngee-icon ezinekhowudi zombala ukuze kulungiswe ukungakwazi ukufunda nokubhala kwabasetyhini, iyaguquka isuke kwimilinganiselo ebandayo ibe ziintsinjana zokulingana kwezentlalo,” utshilo umcebisi ngezesini kwiBhanki yeHlabathi uSarah Karim. E-Rwanda, "iZikolo zezobuGcisa zabasetyhini" ezikufutshane nezikhululo zokumpompa ezisemgangathweni ziye zaqeqesha amagcisa amabhinqa angama-3,000 asekuhlaleni, i-28 yawo ngoku ihleli kwikomiti yokuhlolwa kwezobugcisa ye-UNDP.

Inguquko eqhutywa yiDatha: Ukusuka kwiFama ukuya kwiZisombululo eziSekwe kwiLifu

Idatha yokusebenza yemihla ngemihla evela kwiimpompo zothungelwano ivuselela inguqu kwezobuchwepheshe. IZambia isebenzisa i-AI ukuqikelela ukusilela kwezixhobo, ukuphucula ukusebenza kakuhle kwesicwangciso samanzi asemaphandleni ngama-40%. Iqonga leWWF elithi "Amanzi acocekileyo - iMigangatho yokuQala" lidibanisa ulondolozo lwezityalo nezilwanyana ezohlukeneyo kwindawo yokumpompa, ukunciphisa ukuphazamiseka kwezityalo ezisengozini nge-19%. I-FAO iqikelela ukuba ngo-2030, izixhobo ezisemgangathweni ezenziwe ngedatha yezolimo ziya kunceda i-Afrika engezantsi kweSahara ukunciphisa i-11 yezigidi zeetoni zelahleko yokutya.

"Ezi datha zichaza kwakhona ixabiso 'lamandla ohlaza'," utshilo uMlawuli wezobuGcisa weWWF uMark Miller. "Xa ukuchaneka kwe-screw torque iba ngumgangatho wamazwe ngamazwe, akuchaphazeli nje ubomi besixhobo kodwa umgangatho wobomi wezigidi."

Ixesha lokuLingana kwamandla liyaqala

Icwangciselwe ukwamkelwa okokugqibela ngo-2025, i-DC Solar Submersible Pump Technical Specification ibandakanywe kwi-World Bank's "Rural Infrastructure Financing Framework," ekulindeleke ukuba isebenzise ngaphezulu kwe-10 yeebhiliyoni zeerandi kutyalo-mali. Ngokuhlwa eKajiado, uMargaret ujonga igophe lempompo yakhe yokuphuma kwamanzi-amanani afuzisela utshintsho lwamandla ohlaza kwihlabathi: ukusuka kwizithembiso zengqungquthela yemozulu ukuya kwinkqubela phambili ebonakalayo kwihektare nganye.

Ukuqukumbela

Njengoko imigangatho yezizwe ngezizwe ihambelana neemfuno ezisezantsi kunye nokuveliswa kwezinto ezintsha zaseTshayina kusabela kwiminqweno yaseAfrika, ukubekwa emgangathweni kweempompo zesolar zeDC ezingaphantsi kwamanzi kubonisa isiganeko esibalulekileyo kukulingana kwamandla. Oku kungaphezulu koloyiso lobugcisa; bubungqina besakhono soluntu sokwenza izisombululo eziqinisekisa isidima kunye nokukhula naphi na apho ilanga likhanya.
