We show that the DUNE liquid-argon detector, with modest investments to target solar neutrinos, could detect $\sim 10^5$ signal events above 5 MeV in 100 kton-year, with low backgrounds. These data will open unprecedented opportunities for discovery. New particle physics may be revealed through the matter effect on solar neutrinos relative to reactor neutrinos, where there is already a $\sim 2\sigma$ discrepancy and the JUNO experiment will greatly improve the reactor measurement. New astrophysics may be revealed through the most precise measurement of the 8B flux and first detection of the hep flux. Without a modified DUNE, these opportunities will remain hard to reach.
