Main Components Used to Build a Solar Power System
On an annual basis, the sun generates over 10, 000 times the amount of energy that the entire world consumes. By effectively tapping this virtually inexhaustible energy source, energy needs of today can be met easily. Besides, with the steady increase in the energy prices and rising concerns about global warming, it has become necessary to consider some clean and efficient alternative sources of energy. Many people have started building solar power systems in their homes to utilize the benefits.
Following are the main components required to build solar power systems:
1. Solar Modules: Solar modules are the most important devices required to build solar power systems. These modules are directly exposed to sunlight and convert solar energy into electrical energy. Solar modules are generally mounted on a steel frames and installed on the rooftops of houses or offices.
2. Power Converter: The power converter accumulates the current generated by the Solar Modules and converts the Direct Current (DC) to Alternating Current (AC). The electrical power we normally use in offices or houses is in the form of AC.
3. Electrical Service Panel: From the power converter, the current flows directly towards the Electrical Service Panel. This is one of the main components required for building solar power system and is responsible for distributing the current throughout the office or house for use.
4. Utility Electric Meter: Sometimes, the solar power system produces current in an excess amount. This excess current flows into the grid through a Utility Electric Meter. Due to this, the electric meter will move backwards and this builds a credit with the utility company in countervailing future usage. This process is Net Metering. It is looked after by State Level Electricity Policy.
5. Utility Grid: The utility grid may be referred to as the state infrastructure, which connects houses and other commercial establishments to electricity generating assets. In an event of excess production of solar power, utility grid will automatically transfer the excess electricity.
Although building solar power systems may require heavy investment in the beginning, they can be very beneficial in long run.
By building solar power , you can harness the solar energy in an efficient manner.

Negative Voltage -- WTF?
Okay, I'm learning all about signals in class -- rf frequencies, and waves in a circuit. I understand now that when we speak about negative voltage in an AC circuit, we mean that we've reversed current flow direction. However, apparently negative voltage can exist in a DC circuit as well. This is where I become confused, because I've always thought that voltage could only exist as greater-than or equal-to 0. My logic tells me that one either has electrons flowing at a voltage or one does not have a current at all. Can you explain negative voltage for me? Please?! Thanks.

Electric current flow direction? Do I have this right?
I've heard a few different stories about how electrical current flows. Assuming the only actual moving particles are electrons because we're using a copper wire or something (I don't want to even start on protons in electricity), it's pretty clear that the electrons themselves are moving from the negative to the positive. Now, I've heard that this is the actual flow from some places. Other places, I've heard that while the electrons are flowing from negative to positive, the actual flow of electricity is the opposite direction. From my understanding, if you have one electron pulled towards a positive electrode, a nearby electron will snap into it's place, etc causing an immediate chain reaction shifting all the electrons in the wire one place towards the positive. While the electrons move one spot towards the positive, the current is actually the flow of that empty space soon (very soon) to be filled by another electron.... and that empty space travels against the actual flow of physical electrons. So electrons travel from negative to positive, but the current is the momentary positive space that tracks back to the negative terminal. The raw energy of the system is in the difference of positive/negative voltage, and the energy is used when a positive space tracks towards the negative and evens them out a little. So if you have a current traveling to the right powering a lightbulb, it's actually electrons moving fairly slowly to the left that's causing the reaction producing light. And, therefore, the power isn't in the electrons, it's in the shifting of them due to voltage differences. It's that positive impulse that brings all the power. Am I getting any of this right? Or is it actually that electrons bump each other forward, where if one moves forward the negative charge pushes another one off, etc? But then they would be moving in the same direction as the current... I'm confused.
Thanks for any answers!
