  Super-Kamiokande-IV (SK-IV) data taking began in September of 2008, after
upgrading the electronics and data acquisition system. Due to these upgrades
and improvements to water system dynamics, calibration and analysis techniques,
a solar neutrino signal could be extracted at recoil electron kinetic energies
as low as 3.5 MeV. When the SK-IV data is combined with the previous three SK
phases, the SK extracted solar neutrino flux is found to be
$[2.37\pm0.015\mbox{(stat.)}\pm0.04\mbox{(syst.)}]\times10^6$/(cm$^{2}$sec).
The combination of the SK recoil electron energy spectra slightly favors
distortions due to a changing electron flavor content. Such distortions are
predicted when assuming standard solar neutrino oscillation solutions. An
extended maximum likelihood fit to the amplitude of the expected solar zenith
angle variation of the neutrino-electron elastic scattering rate results in a
day-night asymmetry of $[-3.2\pm1.1$(stat.)$\pm0.5$(syst.)]$\%$. A solar
neutrino global oscillation analysis including all current solar neutrino data,
as well as KamLAND reactor antineutrino data, measures the solar mixing angle
as $\sin^2\theta_{12}=0.305\pm0.013$, the solar neutrino mass squared splitting
as $\Delta m^2_{21}=7.49^{+0.19}_{-0.17}\times10^{-5}$eV$^2$ and
$\sin^2\theta_{13}=0.026^{+0.017}_{-0.012}$.
