Partial evolutionary sequences have been calculated for several solar models with central black holes of the order of one hundred-thousandth of a solar mass. If these are assumed to radiate their Eddington-limiting luminosity, the central temperature is depressed to the extent that the predicted count rate for the Cl-36 solar neutrino experiment nears the current upper limit of 1 SNU. This occurs when the auxiliary energy source provides about half of the solar luminosity. Count rates below this limit would result from an even larger black-hole luminosity. Consequences for stellar evolution of the occasional presence of black holes inside normal stars are discussed.
