Solar Photo-voltaic provides Electrical Energy for powering Lighting and other devices.

A Solar PV panel produces DC Voltage by converting Sunlight into Electricity.

This DC Voltage can be used to Charge a Battery and store the energy for use at any time.

Now we have two options:
1. Convert DC Voltage of the Battery into AC like we have from our AC Mains supplied by our Electric Company.
2, Use this directly for Powering DC Powered devices.

In option 2 we have a major advantage - Higher Efficiency

This is where we are trying to develop devices which you can use directly off a Battery and use Solar more efficiently
