Solar Panel is the device that is used to connect solar energy to the electrical energy. Solar Panel production is very safe as per the IEA (International Energy Agency).They have photo voltaic cells that are assembled together. The work of PV cells is to connect solar energy directly to the electricity. The collection of PV molecules is basically known as PV panel. The cells are arranged in parallel way or in series next to one another to get the desired voltage. A PV junction box works as the output interface at the back of the solar panel. (1)
The other one is MC4connectors which provides water proof protection to the whole system. The other important and motor cable thing is that USB interface can also be used for this. The specification of solar panels is obtained under the standard conditions.
The PV junction box works as output because it is attached to the back of solar panels. To take the desired output module electrical connections are made in series. The PV are arranged in parallel way to provide desired voltage capacity as input. Some PV modules is focused by mirror or lenses. These are called special model concentrators. This can reduce the high cost cells such as gallium arsenide. This can minimize the cost of PV module very much.
The conducting wires are made up of silver, copper or nonmagnetic conductive transition metals to take off the current. Their sizes are designed according to the capacity. In the case of external use, bypass diodes can be incorporated because they can minimize the module sections. PV modules also use racking component, brackets, reflector, shapes and trough to support the panel structure quite good or in better way.
The irradiance of 1,000 w/m2, solar spectrum of AM 1.5 and the standard temperature for this is 25 cͦ. The performance of PV module is under STC. For the standard performance, they are oriented in the same direction perpendicular to direct sunlight. Then this will provide the optimum performance.
As the research shows that the path of sun varies with the latitude. So, it can affect the overall performance of the panel because different voltage of current can also affect the overall performance.
The maximum voltage used by PV module is Voc which is generally known as open circuit voltage. It can be measured directly on module’s terminal. Wp is the peak power rating under the standard conditions. The chemicals that are very effective to use as semiconductor as to create the donor or acceptor that is very much close to the conductor bands of valence. This chemical is called boron. This allows for free energy conduction or emphasize the conversion of photons to the electron.
As the companies says that the most common way or location to install solar panel is roof. The roof is best location because it is directly exposed to the sunlight. The panel take the maximum amount of sunlight on the roof. If the roof is not suitable for the installation of solar panel it can be adjusted on the ground. But remember that it can’t block the sunlight. There are following steps for the installation of solar panel.
- Setup scaffolding.
- Install solar panel mounts.
- Wire the solar panel.
- Install solar inverter.
- Install solar panel.
- Bond solar invertor and solar battery.
- Connect invertor to the solar unit. Start and test the solar panel.
First, we must do scaffolding to ensure the safety because safety comes first in the whole procedure. This occurs when the installation process is on the roof. Then we have to setup mounting system. This will support the base and it will be tilted at the angle of 180 to 360 to take the advantage of maximum sunlight.
After the mount setup the panel has to set up the mounting structure. To stay stable, make sure to tight all the bolts and nuts.
Next step is electrical wiring. MC4 is most suitable for all the types of wiring. Break off all the household electricity during installation.
Inverter setup is the next step. It must be installed indoor or outdoor or must be near to the main panel. It is typically connected to the system.
The next step is setting solar inverter and solar battery. It will be helpful in saving solar energies when there is a cloudy weather. It will also cost lesser for the battery storage system and consumer unit is the part where the inverter should be connected. If you want to check how much electricity is generated in different times, you have to connect this with a computer or laptop.
Other devices are also helpful in this regard. It will also help in time where you have to use washing machine or other appliances. The final step is switch on the power to test the solar panel installation is completed. After the satisfaction the solar panel installation is completed.
The cost for the solar panel is according to the size of the house. If the home size is 1500 sq. ft. average cost will be $ 7,140 – $ 8,925. If the house is 2,000 sq. ft. the cost will $9,520 – $ 11,900. If the house is 2,500 sq. ft. the cost price average is $ 11,900 – $ 14,875 and the house is 3,000 sq. ft. of the cost will be $ 14,280 – $ 17850.
Best solar panel companies

Returns on investment solar panel
The returning range is 10% to 30% or more than that. If you are living in high rate energy areas, it will be very good for the initial investment. There are many factors that can affect the initial ROI that includes.
- Electricity rates.
- Property characteristics.
- Business benefits.
