Hnub ci zog
Lub zog hnub ci ntawm Saint Paul Public Schools
Solar zog yog ib tug zoo txhais tau tias ntxiv txo cov carbon footprint ntawm ib lub tsev twb npaum lub tsev twb npaum lub tsev. Txawm li ntawd los, hnub ci zog yuav tsum tsis txhob siv los counteract zog khib nyiab, tshwj xeeb tshaj yog thaum zog efficiency thiab/los yog kev txuag txuj muaj. Lub SPPS facilities zog pab neeg no muab ib feem ntau rau tej yaam num uas tsis muaj nqi tsawg, muaj shortback lub sij hawm, thiab muaj ntxiv cov kev pab cuam uas tsis yog-zog, xws li txo maintenance, zoo tuaj, thiab kev noj qab haus huv thiab/los yog kev ruaj ntseg txhim kho. Lub zog pab neeg no nplooj siab txo peb reliance rau pob txha fuels los ntawm proven, nqi zoo tshaj plaws.
HOM HNUB CI
Muaj ob hom hnub ci zog tshuab: photovoltaic thiab hnub ci thermal. Photovoltaic (PV) vaj huam sib luag siv semiconductors transform hnub ci zog rau hauv hluav taws xob uas yuav siv tau nyob rau hauv ib lub tsev los yog xa rov qab mus rau lub hluav taws xob grid. Solar thermal panels muaj ib tug ua hauj lwm kua uas absorbs hnub ci zog nyob rau hauv daim ntawv ntawm tshav kub uas ces siv los ua dej kub siv nyob rau hauv lub tsev. SPPS tam sim no muaj ib yam ntawm txhua hom hnub ci array.

Zej zog Solar Subscription
Tus nqi zoo ntxiv hnub ci zog rau peb portfolio yog subscribe rau ib lub zej zog hnub ci. Ib lub vaj hnub ci yog ib lub zej zog sib koom PV hnub ci array los yog "vaj" uas muab hluav taws xob rau grid-txuas nrog subscribers. SPPS yuav nkag mus rau lub hwj huam Purchase Agreement (PPA) nrog ib hnub ci tsim tawm tso siv ib lub vaj hnub ci. Nyob rau xyoo 2018 SPPS tawm ib RFP rau hnub ci developers uas pw tawm cov nqe lus ntawm daim ntawv pom zoo kom SPPS yog tiv thaiv tau lub vaj huam sib luag underperform thiab tias SPPS cov kev pab cuam los txo hluav taws xob nqi thaum tseem ensuring tias lub zog txuag kev ntsuas twb nyob rau hauv qhov chaw SPPS nyob twj ywm rau hauv koog tsev kawm ntawv. SPPS tau txais tsis teb rau qhov uas qhia cov RFP hauv 2018. Nyob rau hauv Minnesota, nws muaj nws ib clause tias lub vaj hnub ci yuav tsum tau nyob rau hauv ib lub nroog adjoining. SPPS nyob hauv ramsey County, ib lub nroog urban heev. Feem ntau tshiab los yog tam sim no hnub ci tej yaam num yog ua nyob rau yav qab teb Minnesota cheeb nroog
Solar Roof Feasibility txoj kev tshawb no
Ntxiv hnub ci arrays yuav tau ntsia rau lub-ru tsev ntawm SPPS vaj tse, tiam sis muaj ntau yam kev xav uas yuav tsum tau coj mus ua nyiaj, xws li cov nyiaj txiag kev pab cuam, maintenance/tswv cuab implications, raws li txoj cai, thiab tej yam. Ib hnub ci array feasibility txoj kev tshawb no yog undertaken nyob rau xyoo 2019 los txiav txim seb spPS vaj tse yuav zoo txheeb rau installation ntawm ib rooftop hnub ci array.
