 **Lumens:** an exact measure of quantity of light. A 60-watt incandescent light bulb and an 18-watt compact fluorescent light bulb each produce about 1,000 lumen.  **Lumens:** an exact measure of quantity of light.

 **MPP- tracking - Maximum Power Point Tracking:** - a transformer has to deliver the max. power at all possible light circumstances which goes with a certain voltage delivered by the panel. This voltage depends on the amount of light falling on the panel. Power is the product of voltage and current and hence at a given voltage there is a specific current. At every voltage there is an optimal current (maximum power point). In the inverter the electronic parts look under every circumstances this optimal point: MPP-tracking **MPP- tracking - Maximum Power Point Tracking:** - a transformer has to deliver the max. power at all possible light circumstances which goes with a certain voltage delivered by the panel.
