Solar Power Efficiency - Eliminate Your Electric Bill

Solar power efficiency is a key term when it comes to determining the economic feasibility of using solar panels. The efficiency of the solar panels energy absorption coupled with the energy output are very important. In other words, the amount of energy in compared to the amount of energy out.

A solar panel works by absorbing energy from sun light during peak sun hours, or the time when the sun is strongest. This energy, in the form of photons, is absorbed by a substance like silicone.

This absorption knocks loose electrons to run free. Next, an electrical field channels the electrons along a specified path creating a current. Power Efficiency Guide This current is called direct current; you may know it better as the type of energy batteries use. As we, all know our homes are not battery powered; therefore, this must be converted into alternate current.

Now that is a simplistic look at a solar panel system but as you can see, there are many interdependent parts that will need to work efficiently to maximize productivity. What are some things that can affect efficiency?

One of the most important aspects of solar power is the solar panels. These panels have very specific requirements to work effectively. The first is the tilt; a solar panel should be tilted in direct proportion to your geographical latitude. For instance if your home sits near 40 degrees latitude then this is the angle degree required by your solar panel. If the tilt is not sufficient then the solar power efficiency will be affected.

More importantly, than the angle is being sure that there is no shading or blocking of the panel. If even one cell in your solar panel is shaded, the output is cut by 50%, a great loss in solar power efficiency.

All the components of the solar panel are potential areas for loss in efficiency. Technology is addressing more and more the need for better quality solar cells. One new innovation on the market today are solar cells on film. This smaller lighter material makes it much more cost effective to produce them as well as being more efficient.

Equally important is the efficiency of your charge converter better known as a charge regulator. This device regulates the flow of electric into the battery. When the battery gets low the regulator allows energy in, but not too much energy, it also limits the ingoing charge to protect the battery. Overcharging or undercharging a battery is detrimental to the life of the battery.

The type of battery used is important to the overall solar power efficiency. A small insufficient battery will wear out quickly costing you more for operation. A good economical choice is a marine deep cycle battery; they have the capacity and strength to hold up to intensive use.

The final piece in the puzzle is your power inverter. An inadequate inverter can lead to a loss in usable electricity. When choosing a system it is important to be sure all these components are in good working order and efficient.
