To achieve social responsibility:
We are daily using lots of fossil fuel and other carbon compounds, that are polluting our environment. Initiating Global Warmning, environmental imbalance, ozone layerdepletion and which inturn is a big threat to the future human race.
Solar energy is a clean and a green energy, harnessing it will not pollute the environment or generate any adverse effects.
To achieve financial goals:
Solar energy after installation is INFLATION FREE source of power, which means you are not dependent on fluctuating raw material cost for your generation of power...This adds to energy independence.
Also in countries where conventional power is expensive and wind energy is not regular solar energy tends to be the most efficient solution.
In countries where power is not reliable, we can opt for green source of energy to replace diesel generators or battery backup.
The BC548 is a general purpose epitaxial silicon NPN bipolar junction transistor found commonly in European electronic equipment. The part number is assigned by Pro Electron, which allows many manufacturers to offer electrically and physically interchangeable parts under one identification. The BC548 is commonly available in European Union countries. It is often the first type of bipolar transistor young hobbyists encounter, and is often featured in circuit diagrams and designs published in hobby electronics magazines.
If the plastic TO-92 package is held in front of one's face with the flat side facing toward you and the leads downward, (see picture) the order of the leads, from left to right is collector, base, emitter.
