Mphamvu ndi kuchuluka kwa magetsi komwe batire ya solar ingasunge, komwe kumayesedwa mu kilowatt-hours (kWh). Mabatire ambiri a solar apakhomo amapangidwa kuti "azitha kukhazikika," zomwe zikutanthauza kuti mutha kuphatikiza mabatire angapo ndi makina anu osungira solar-plus-plus kuti mupeze mphamvu yowonjezera.
Ngakhale kuti mphamvu ya batri yanu imakuuzani kukula kwa batri yanu, sikukuuzani kuchuluka kwa magetsi omwe batri lingapereke panthawi inayake. Kuti mumvetse bwino, muyeneranso kuganizira kuchuluka kwa mphamvu ya batri. Ponena za mabatire a dzuwa, mphamvu ya batri ndi kuchuluka kwa magetsi omwe batri lingapereke nthawi imodzi. Imayesedwa mu kilowatts (kW).
Batire yokhala ndi mphamvu zambiri komanso mphamvu zochepa ingapereke magetsi ochepa (okwanira kuyendetsa zida zofunika zingapo) kwa nthawi yayitali. Batire yokhala ndi mphamvu zochepa komanso mphamvu zambiri ingathe kuyendetsa nyumba yanu yonse, koma kwa maola ochepa okha.
