With the technology advances there are so many different solar panel options in the market today. However, their performance is different. This article looks at how different panels differ from each other.

Power Output

Power output usually refers to the DC current that the solar panel is capable of producing. Most solar panels usually have a power rating of between 200 to 350W. The amount of electricity a solar panel is capable of producing is dependent on several factors. The first is size, the larger the solar panel the more the energy it is capable of producing. The angle and direction of your roof is the second factor, it is ideal that your roof be facing south and be between 10 degrees and 60 degrees inclined. The time of year also affects the electricity production. Longer day time means more electricity production. Even though power output is important, you should keep in mind that there are other factors that can affect the amount of power produced.

The Credibility of the Manufacturer
