Withtheincreasinglevelsofrooftopphotovoltaicsystems,theenergyflowbecomes2-way.When thereismorelocalgenerationthanconsumption,electricityisexportedtothegrid.However,an electricitynetworktraditionallyisnotdesignedtodealwiththe2-wayenergytransfer.Therefore, some technical issues may occur. For example, in Queensland Australia, more than 30% of households used rooftop PV by the end of 2017. The duck curve appeared often for a lot of communitiesfrom2015onwards.Anover-voltageissuemayresultastheelectricityflowsfromPV householdsbacktothenetwork.[95]Therearesolutionstomanagetheovervoltageissue,suchas regulatingPVinverterpowerfactor,newvoltageandenergycontrolequipmentattheelectricity distributorlevel,re-conductingtheelectricitywires,demandsidemanagement,etc.Thereareoften limitationsandcostsrelatedtothesesolutions.

Thereisnosilverbulletinelectricityorenergydemandandbillmanagement,becausecustomers (sites) have different specific situations, e.g. different comfort/convenience needs, different electricitytariffs,ordifferentusagepatterns.Electricitytariffmayhaveafewelements,suchas dailyaccessandmeteringcharge,energycharge(basedonkWh,MWh)orpeakdemandcharge(e.g. a price for the highest 30min energy consumption in a month). PV is a promising option for reducingenergychargewhenelectricitypriceisreasonablyhighandcontinuouslyincreasing,such asinAustraliaandGermany.However,forsiteswithpeakdemandchargeinplace,PVmaybeless attractive if peak demands mostly occur in the late afternoon to early evening, for example residential communities. Overall, energy investment is largely an economical decision and it is better to make investment decisions basedon systematical evaluation of optionsin operational improvement,energyefficiency,onsitegenerationandenergystorage.
