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.
Electricity from solar panels is 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.
The sun charges the solar panel and they are actually very cheap than normal fossil fuel electricity which is taken from the grid parity and the method they is using light energy from the photons of the sun.
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.
Depending on whether the solar panels are connected in series or parallel makes it possible to have abundant electricity that may cover all the residential houses.
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.
Solar panels use solar inverters to convert direct current power to alternating current and this output from the cells of solar is applied to resistance which goes to the solar cells and this brings about maximum power.
If the solar panels are wired in series the micro-inverters brings about maximum output depending on the obtainability of sunlight.
Most of the solar panels have a special method that makes maximum use of power optimizers by using DC TO DC converters which maximizes the harvesting of power from the photovoltaic systems and 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.
