PVGIS vs Project Sunroof: Qhov kawg 2025 Sib piv

Dab tsi yog PVGIS?

Lub Photovoltaic Geographical Information System (PVGIS) yog ib daim ntawv thov web pub dawb uas tso cai rau tus neeg siv tau cov ntaub ntawv ntawm hnub ci hluav taws xob thiab photovoltaic system zog tsim, nyob rau hauv feem ntau ntawm lub ntiaj teb no. PVGIS yug los ntawm lub zeem muag zoo nyob rau hauv Lub Chaw Tshawb Fawb Sib Koom (JRC) ntawm European Commission thiab tau hloov mus rau hauv ob qho tib si lub tsev kawm ntawv dawb version thiab kev lag luam siab tshaj platform.

PVGIS24 muab kuv qhov tseeb kuv xav tau, raws li cov neeg siv uas tso siab rau nws qhov tseeb rau hnub ci kev tshaj lij tsom xam. Lub platform muaj:

• PVGIS 5.3: Dawb version nrog txwv peev xwm
• PVGIS24: Lub laij lej txhim kho pom ntawm PVGIS.COM nrog advanced nta thiab niaj hnub interface

Yog xav paub ntxiv txog PVGIS peev xwm, mus saib lub ua tiav PVGIS solar calculator guide.

Google Project Sunroof yog dab tsi?

Google's Project Sunroof yog qhov cuab yeej online pub dawb uas pab cov tswv tsev suav hnub ci lub zog muaj peev xwm raws li lawv cov qauv ru tsev thiab cov qauv huab cua hauv zos. Nws tau tsim nyob rau hauv 2015 los ntawm ib pawg ntawm Google Engineers coj los ntawm Carl Elkin.

Project Sunroof sau cov ntaub ntawv los ntawm Google Maps thiab Google Earth los txheeb xyuas lub tsev lub ru tsev yam ntxwv thiab qhov chaw. Qhov no suav nrog lub ru tsev loj, kev taw qhia, shading, thiab cov ntaub ntawv lub kaum sab xis. Cov cuab yeej siv satellite duab thiab kev kawm tshuab los muab kev kwv yees hnub ci rau cov vaj tsev nyob.

Kev sib piv qhov tseeb: PVGIS vs Project Sunroof

PVGIS Qhov tseeb

Cov txiaj ntsig tau raug ncaj ncees (raws li txhua xyoo) txij li ob qho tib si siv cov ntaub ntawv loj los ntawm lub sijhawm ntev. Kev tshawb fawb qhia tau tias PVGIS feem ntau muab cov txiaj ntsig zoo dua li ob qho khoom siv dawb pub dawb rau PV fais fab tiam thaum piv rau kev ntsuas ntawm PV chaw ua si uas twb muaj lawm.

Hauv plawv ntawm PVGIS lies ib tug loj muab tso ua ke ntawm hnub ci irradiation cov ntaub ntawv, sau ntau tshaj ob peb xyoo lawm thiab tas li refined. Tsis zoo li lub regional approximations siv los ntawm lwm yam cuab yeej, PVGIS suav nrog subtle hauv zos variations uas tuaj yeem ua rau txhua qhov sib txawv.

Cov PVGIS24 hwm platform muab kev txhim kho qhov tseeb los ntawm:

• Advanced satellite data integration
• Kev txheeb xyuas huab cua kom ntxaws
• Precise local microclimate modeling
• Professional-qib kev suav nyiaj txiag

Qhov project Sunroof raug txwv

Thaum nws los txog rau kev tsom xam hnub ci, Project Sunroof yog cov cuab yeej pab tau. Txawm li cas los xij, peb ceev faj me ntsis txog nws qhov tseeb thaum nws los txog rau cov nqi hnub ci thiab kev txhawb zog. Ntau cov ntaub ntawv Project Sunroof tsis tau hloov kho txij li xyoo 2018.

Piv txwv li, Google kwv yees tias lub hnub ci hauv Houston, Texas, yuav yog li $ 26,000 tom qab siv tsoom fwv teb chaws solar se credit. Siv cov ntaub ntawv hnub ci sab hauv los ntawm 2024, EcoWatch pom tus nqi nruab nrab ntawm lub hnub ci nyob rau hauv Houston yog kwv yees li $36,570. Raws li koj tuaj yeem pom, daim duab los ntawm Project Sunroof yog ntau dua $ 10,000-yuav luag 50% - tawm.

Google hais tias qhov kev kwv yees muab los ntawm Project Sunroof feem ntau muaj tseeb hauv 10-15% rau hnub ci muaj peev xwm, tab sis kev kwv yees nyiaj txiag tsis tshua muaj kev ntseeg siab.

Geographic Kev Pabcuam: Ntiaj teb no vs Regional

PVGIS Ntiaj teb no ncav cuag

PVGIS muab cov ntaub ntawv qhia txog hnub ci hluav taws xob thiab kev ua haujlwm photovoltaic rau txhua qhov chaw hauv ntiaj teb, tsuas yog North thiab South Poles. Qhov txhim kho PVGIS24 tshuab xam zauv npog:

• Teb chaws Europe nrog siab precision
• Teb chaws Africa nrog cov ncauj lus kom ntxaws satellite
• Asia nrog kev pab them nqi
• Tebchaws Asmeskas nrog kev kwv yees txhim khu kev qha
• Oceania nrog kev ua qauv zoo

Project Sunroof Limited Kev Pabcuam

Tam sim no, Google Project Sunroof cov ntaub ntawv tshawb nrhiav tsuas yog muaj nyob hauv Asmeskas thiab Lub Tebchaws Yelemees. Qhov no hnyav heev txwv nws cov txiaj ntsig zoo rau cov phiaj xwm hnub ci thoob ntiaj teb lossis kev sib piv thoob ntiaj teb.

Txog rau thaum xaus xyoo 2020, cov cuab yeej tau npog ntau dua 60 lab lub ru tsev thoob plaws 50 lub xeev hauv Asmeskas, tab sis nthuav dav tau qeeb.
