There are many areas that have no electricity in some parts of the world and people use an alternative method to electrify their houses and the common use is the solar panel where some photovoltaic module device is used.
Arrays of systems of photo voltaic cells which make generation of solar electricity and this may be supplied to residential and commercial applications and each module is rated using direct current output power which is rated in watts.
Solar panels produce limited amount of power but there are many installations that use multiple modules and they include arrays of photovoltaic modules such as solar tracking mechanism, interconnection wiring, a battery pack for storage and an inverter.
It is cheaper to use electricity if the house is not connected to the grid to power the house or any building that may require electricity as well as heating water.
There are many kind of solar panels and some are rigid while the others are flexible and they are all protected from vagaries of nature.
Weather proofing the connections in all the systems is very important and when they are connected in series it is possible to get some desired voltage output but when they are connected in parallel there is more current capability.
The wires that does the conducting may use non-magnetic transition metals, and copper or silver but the bypass dioxides might use externally so as to maximize the modules output and where the solar panels have concentrators where light is focused in mirrors or lenses which are small cells it makes it possible to have the high cost per unit area in a lesser cost.
The photovoltaic cells may yield electricity which ranges from light frequencies but normally covers a wide range of infrared and ultraviolet diffused light and this makes the energy from the sunlight to be wasted by the solar panel but they may provide higher illumination by using monochromatic light.
The solar panel uses lower wattage for lighting the residential house but the power may be more if there is an inverter used.
It is it probable to produce much output than other common panels which may be wired in series and the micro-inverters brings about maximum output depending on the obtainability of sunlight.
The nominal voltage output of the solar panel changes in load conditions, temperature and lighting makes it possible to have specific voltage which the solar panel operates.
It is possible to know how much electricity is being produced in the residential house by measuring it using a voltameter.
