MPT (Maximum Power Tracking)

The current delivered by a Photo Voltaic Module (Solar Panel) varies over the course of the day, and to a greater degree across seasons and temperature conditions.  The result is that much of the energy delivered to the battery cannot be stored because of the mis-match in current.   Under these conditions the needs of the battery are not always well matched to the power characteristics of the solar panel.   The SO-Bright^® MPT algorithm essentially marries the power characteristics of the two devices, ensuring that the maximum amount of energy available from the solar panel finds its way into the battery. SolarOne has measured over 30% improvement in charging efficiency with this unit.

Winter in the northern latitudes is the greatest challenge for solar powered lighting. The system is required to work through extended night time hours and has fewer daytime hours to collect and store energy.  This advancement in solar powered lighting control addresses charging efficiency when and where it is needed most.  Users will benefit by being able to use smaller, more cost effective modules than in the past, without compromising on power or aesthetics.
