Operating characteristics of solar power light for park in snowy country

摘要

We operated a solar power light for park in snowy country. The light consists of 8 solar panels paralleled, 2 batteries paralleled, a 6-watt LED and a control circuit. The light worked perfectly in last winter season, so that the light can be useful in snowy country. We obtained some data on the way of the run-test, and the data are enough. In order to make the system optimized, we tried to evaluate the system with simulation.
