Solar Panel which is also called as Photovoltaic panels or PV panels are packaged of internally connected assembly of Photovoltaic cells. An Array of Solar panels connected together as a unit which may also be called as photovoltaic system can be easily used to Generate Electricity for homes, buildings and public lights. The electricity generate is also used for Commercial purposes.
The Output of each Solar panel is DC (Direct Current) and is rated according to its output capacity ranging from 80 Watts to 350 Watts. Solar Panels of the same rating might vary in efficiency thus their size depends upon their efficiency in converting Solar Rays (sunlight) into Electricity.
As a single Solar Panel can only produce output (Electricity) based on its rating which is not adequate to power a house alone, almost all solar installation have more than 1 solar panel. Thus increasing the capacity and redundancy of the system. A Solar power system mainly consist of an array of Solar panels, inverter to convert generate DC power into AC power which is used by Devices in home, and Battery to store electricity generate during day time for its utilization during night.
As we know, Solar panels uses Sun Energy (photon) to generate Electricity through the photvoltaic effect, Solar panels are equipped with Solar Cells which are used to collect Solar Energy (photons), converted them into Electricity (DC) via the Photovoltaic effect then transfer the generate electricity to be stored in the Battery for further use. The Majority of Solar panels use wafer based crystalline silicon cells or thin film cells made from cadmium telluride or silicon. There are many types of Solar panels in use, they utilize the appropriate solar cells configuration and structure.
Solar panel system is a proven way to make Electricity at Home. There are many variations of Solar panels thus making it really easy to chose the necessary type of solar panel to be installed. For home installation, many prefer to use Roof Mounted Solar panels. This genre of Solar panels are specially made considering local in-house use. As our Aim is to Generate Electricity at Home, we will prefer to use Roof Mounted Solar Panels as they are best suited for our needs. If you don’t want to install solar panels on your roof, then there are other variations of Solar panels which can be used.
The cost of Solar panels largely depends upon the desired output for a day. If the desired output is 500 Watts, there can be 2 solar panels with rating of 250 Watts each or 1 of 300 watts and other of 200 Watts.
Here are some Solar panels best suited for Residential use.
Now, this Solar panel has Rating of 180 Watts which is quite good at a price for $396.
As discussed earlier, depending upon your desired output, you should buy the relevant solar panel(s).
