"The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14... in February of 1906," states NASA's website for Solar Cycle Prediction managed by the Marshall Space Flight Center in Huntsville Alabama. Each sunspot cycle lasts around 11 years and the number of sun spots is linked to levels of solar irradiance - although the variation in solar irradiance between peak and trough is small.
