Know How Many Solar Panels You Need?

Solar panels are environmental free and open source of power whose basic requirement is to know how many panels are needed for your household.  There are some factors you need to consider before installing the solar panel array. Such factors vary from your budget to the kind of solar tech array you need as well as your desired consumption.

It is important to have an idea of the energy consumption you require. The amount of solar energy each panel holds determines how many panels will be installed in your household.  An ordinary household is said to use approximately 8000-9000kwh per annum, and therefore a substantial number of panels will be required especially if they provide around 100-200 watts energy.  However, depending on your energy use, you might be required to install minimal panels. Building your solar panel effectively reduces the manufacturing price to lower than $200 for a 36cell solar panel.
