The potential of the GENIUS proposal [1] to measure the spectrum of low energy solar neutrinos in real time is studied. The detection reaction is elastic neutrino-electron scattering $\nu + e \rightarrow \nu + e$. The energy resolution for detecting the recoil electrons is about 0.3 %, the energy threshold is a few keV. The expected number of events for a target of one ton of natural germanium is 3.6 events/day for pp-neutrinos and 1.3 events/day for 7Be-neutrinos, calculated in the standard solar model (BP98 [2]). It should be feasible to achieve a background low enough to measure the low energy solar neutrino spectrum.
