Photovoltaic Solar Facts You Must Know
By now nearly everyone can advise you what a photovoltaic cell is but when it comes to all the details relating to kilowatt sizing, or even the area which these panels covers on a roof that is when questions arise. The versatility that solar electric panels bring offers a wide range of possibilities for solar designers that allows them to create configurations that can cover virtually any surface area. Ultimately the design of any particular solar configuration is much more of a balance involving the power requirements necessary for any given installation and the aesthetic appearance desired for your house or business structures.
Photovoltaic solar panels are available in a wide array of wattage sizes that is ever increasing as their technologies are advanced by solar manufacturers and the same is true for the dimensions they are available in as well. The “A” typical image many people think of when it comes to the particular shape of a cell is rectangular if the fact of the matter is that they can be created in practically any geometrical shape increasing their versatility. Good quality renewable energy distributors know this and rehearse all of these variables within their designs in order to provide not only the correct power output required, but additionally a design that is as pleasing to the eye as possible in every photovoltaic solar matrix they design for his or her clients. These are also very good reasons why the Do-It-Yourselfer’s (DIY) are better off leaving solar design to the professionals that are certified and incredibly capable of creating systems which encompass most of these factors.
One of the most repetitive questions asked is, “How many panels will i need for an “X”kw cell system”? The second most repetitive question asked is, “How much roof area will an “X”kw cell system cover”? Given that photovoltaic solar panels are manufactured in many wattage values the easiest method to approach this is using basic addition. Suppose you would like to design a 2kw solar matrix for your house and you have chosen a 175watt panel with a width of 808mm (or 2.6509 feet) and length of 1580mm (or 5.1837 feet). Considering the fact that you are targeting 2kw as your matrix size it will require 12 of these solar panel systems to equal 2.1kw, and 12 of these solar panels will cover an area of approximately 165 square feet. If your only issue is to achieve the power creation of a 2kw photovoltaic cell system then with all the standard rectangular panel will suffice and you need to decide what type of racking to mount them also in order to achieve the optimum quantity of sunlight. However, if aesthetics can be a major concern i then would strongly recommend seeing a NABCEP certified solar installer who are able to design this system with this in mind. *Note: Utilizing photovoltaic solar panels other than that of your standard rectangular or square dimensional configuration will come at an increased expense per panel as these must be custom made per the needs you have.
