Masiku ano, anthu ochulukirachulukira akufuna kuphatikiza pampu yotenthetsera mpweya ndi dongosolo la Solar PV kuti apulumutse mphamvu zambiri. Izi zisanachitike, tiyeni tiphunzire zambiri za kusiyana pakati pa mitundu yamakina a solar PV.
Pali Mitundu itatu Yodziwika bwino ya Solar PV Systems:
Gridi Yolumikizidwa kapena Utility-Interactive Systems
Stand-alone Systems
Zophatikiza Zophatikiza
Tiyeni tiwone Mitundu Itatu ya PV Systems mwatsatanetsatane:
1. Gulu Lolumikizidwa ndi Gridi
Makina a PV olumikizidwa ndi gridi safuna kusungirako batire. Komabe, nthawi zonse ndizotheka kuwonjezera batire ku solar yolumikizidwa ndi grid.
(A) Makina a PV Olumikizidwa ndi Gridi opanda Battery
Dongosolo lolumikizidwa ndi gridi ndikuyika koyambira komwe kumagwiritsa ntchito inverter yomangidwa ndi grid. Ndi yabwino kwa iwo amene akufuna kusankha kukhazikitsa solar kuti agwiritse ntchito kunyumba. Makasitomala atha kupindula ndi net metering. Net metering imatilola kulozeranso mphamvu zilizonse zotsala ku gridi. Mwanjira imeneyi, makasitomala amayenera kulipira kokha chifukwa cha kusiyana kwa mphamvu zomwe amagwiritsa ntchito.Makina olumikizidwa ndi grid ali ndi ma solar omwe amamwa ma radiation a solar, omwe amasinthidwa kukhala Direct current (DC). DC imagwiritsidwa ntchito ndi inverter ya solar system yomwe imasintha mphamvu ya DC kukhala alternating current (AC). AC imatha kugwiritsidwa ntchito ndi zida zapakhomo momwe zimatengera grid system.
Ubwino waukulu wogwiritsa ntchito makina olumikizidwa ndi gridi ndikuti ndi otsika mtengo kuposa mitundu ina ya solar PV system. Kuphatikiza apo, imapereka kusinthasintha kwapangidwe chifukwa makinawo safunikira mphamvu zonse zapakhomo. Chofunikira chachikulu cha dongosolo lolumikizidwa ndi gridi ndikuti silipereka chitetezo chilichonse.
(B) Makina a PV Olumikizidwa ndi Gridi okhala ndi Battery
Kuphatikizira batire mu grid PV system kumapereka mphamvu yochulukirapo kunyumba. Zimayambitsa kuchepetsa kudalira magetsi a gridi ndi ogulitsa magetsi pamodzi ndi chitsimikizo chakuti magetsi amatha kutengedwa kuchokera ku gridi ngati dzuwa silikupanga mphamvu zokwanira.
2. Maimidwe Systems
Dongosolo loyima la PV (lomwe limatchedwanso off-grid solar system) sililumikizidwa ku gridi. Choncho, pamafunika njira yosungirako batri. Machitidwe a Standalone PV ndi othandiza kumadera akumidzi omwe amavutika kuti agwirizane ndi grid system. Popeza, makinawa sadalira kusungirako mphamvu zamagetsi, ndi oyenera kugwiritsa ntchito magetsi monga mapampu amadzi, mafani a mpweya wabwino, ndi makina otenthetsera a solar. Ndikofunikira kulingalira kampani yodziwika bwino ngati mukufuna kupita ku pulogalamu yoyimirira ya PV. Izi ndichifukwa choti kampani yokhazikitsidwa idzapereka zitsimikiziro kwa nthawi yayitali. Komabe, ngati makina odziyimira pawokha aganiziridwa kuti agwiritsidwe ntchito m'nyumba, amayenera kupangidwa m'njira yoti athe kuthana ndi zosowa zamphamvu zapakhomo komanso kuyitanitsa mabatire. Makina ena oyimira a PV alinso ndi majenereta osunga zobwezeretsera omwe adayikidwa ngati gawo lowonjezera.
Komabe, makonzedwe oterowo angakhale okwera mtengo kuwakhazikitsa ndi kuwasamalira.
Kumtunda komwe kumalumikizidwa ndi makina oyimira dzuwa a PV ndikuti amafunikira kuyang'ana kosalekeza motsutsana ndi kuwonongeka kwa ma terminal ndi ma electrolyte a batri.
3. Mitundu Yophatikiza PV
Dongosolo la hybrid PV ndi kuphatikiza kwa magwero angapo amphamvu kuti apititse patsogolo kupezeka ndi kugwiritsa ntchito mphamvu. Dongosolo loterolo limatha kutengera mphamvu kuchokera ku magwero monga mphepo, dzuwa, ngakhale ma hydrocarbon. Kuphatikiza apo, makina a hybrid PV nthawi zambiri amathandizidwa ndi batri kuti apititse patsogolo magwiridwe antchito. Pali ubwino wosiyanasiyana wogwiritsa ntchito makina osakanizidwa. Magwero ambiri a mphamvu amatanthauza kuti dongosolo silidalira mphamvu iliyonse. Mwachitsanzo, ngati nyengo si yabwino kutulutsa mphamvu yokwanira ya dzuwa, gulu la PV limatha kulipiritsa batire. Mofananamo, ngati kuli mphepo kapena mitambo, makina opangira mphepo amatha kuthana ndi zofunikira zolipiritsa batire.Makina a Hybrid PV ndi oyenerera malo akutali okhala ndi ma gridi ochepa.
Ngakhale zabwino zomwe zili pamwambazi, pali zovuta zochepa zomwe zimagwirizanitsidwa ndi dongosolo la hybrid. Mwachitsanzo, imaphatikizapo kupanga mapangidwe ovuta komanso kuyika. Kuphatikiza apo, magwero ambiri amphamvu amatha kuonjezera mtengo wam'tsogolo.
Mapeto
Makina osiyanasiyana a PV omwe takambirana pamwambapa ndi othandiza pamagawo osiyanasiyana ogwiritsira ntchito. Posankha kukhazikitsa dongosolo limodzi, tikufuna kupangira ma Grid-Connected PV Systems opanda Battery, mutatha kulinganiza mtengo ndi mphamvu zamagetsi.
