We consider the most general solar model, using the neutrino fluxes as free parameters constrained only by the solar luminosity, and show that the combined solar neutrino data exclude any astrophysical solution at 97% C.L. Our best fit to the Be7 and B8 fluxes is, respectively, < 8% and 37±4% of the standard solar model prediction, but only with a large χ2 (4.8 for 1 DF). This best fit to the fluxes contradicts explicit nonstandard solar models, which generally reduce the B8 flux more than the Be7. Those models are well parametrized by a single parameter, the central temperature.
