Understanding LED light power in Watts and LED lighting

LED Light Power. The power (P) of any electrical device including a LED light is measured in Watts (W), which is equal to the current or electricity drawn (I), measured in ampres, multiplied by the voltage (V). P = V x I. Therefore, the power of the LED light is proportional to voltage and/or current such that a device may have a low voltage but may still draw a very high current and have high

Increasing Solar Panel Efficiency and Output Power

Solar panel output power may be increased via a light concentrator such as a Fresnel lens or mirror. Note that such a lens must be substantially larger than the panel. Also, concentrators may not be practical for a large array, and orientation of the mirror creates an additional tracking problem. Output may be increased by perhaps 50%. Care must be taken to prevent overheating the panel.
