Ingaphandle kwegridi yesistimu yelanga ikakhulukazi yakhiwe ngamaphaneli elanga, amabhethri, izilawuli zelanga, ama-inverter nezinye izakhi. I-current eqondile evela kuma-solar panel igeleza ngqo ebhethri futhi igcinwe. Uma kudingekile ukunika amandla umthwalo we-AC, okwamanje okuqondile ebhethrini kuguqulwa kusuka ku-inverter kuya ekuphumeni kwe-AC, okuwumjikelezo ophindayo wokushaja nokukhipha. Amasistimu elanga angaphandle kwegridi angafakwa futhi asetshenziswe lapho kunokukhanya kwelanga, ngakho amasistimu wamandla egridi zifaneleka kakhulu ukusetshenziswa ezindlini, ezindaweni ezingaphandle kwegridi, izikebhe zokudoba, izisekelo zokuzalanisa ngaphandle nezinye izindawo.I-SAKO inemikhiqizo ehlukahlukene engakwazi ukuhlangabezana nezimo ezingenhla. Uma unezidingo, ungabheka imikhiqizo ye-SAKO bese uthintana no-SAKO .
