The invention relates to a solar LED (light emitting diode) lamp, which comprises a lamp body, a light source and driving components. The driving components comprise a solar panel input port, an energy storage battery port, an LED lamp output port and a driving circuit. The driving circuit comprises an MPPT (maximum power point tracking) +DC (direct current) -DC (direct current) circuit, an LED controller circuit, a solar voltage illuminance detection circuit, a DC-DC driving circuit, a charging voltage current detection circuit, an LED driving circuit, an LED current detection circuit, a DSC (digital signal controller), a key input circuit and an LCD (liquid crystal display) circuit. By integrating a charging controller and an LED driver into a same circuit, installation is simple, and cost is low; by adding a solar maximum power tracking circuit, an MPPT algorithm and an input-and-output protection circuit, the solar LED lamp is more efficient and more reliable, and popularization of the solar LED lamp is realized really.
