Solar Panels:

In the 21st century, the progressive population rate of the world increases the demand for the electricity and the other needs so the energy sources like water and other non-renewable are decreasing day by day. So, in order to save the environment from degradation the best way to produce electricity through natural source which is cost productive as well as safe for the environment is sun by converting them in electricity. Solar panels are the unique technology plates design having the capacity to absorb the rays from the sun at some angle on it and then convert it into the electrical energy connected through these plates in the battery by using photovoltaic mechanism. The more sun the better opportunity to produce the electricity.

Working mechanism of solar plates:

The solar plate consists of the P and N type semiconductors made up of and embedded in between the protective glass and metal detector upward and from beneath supported by the help of conductive metal as a base. When photons enters the plate and penetrate through glass layer then push the mechanism of the P-N junction process and by which the photon converted into the electric volt with the flow of electrons and then store in the battery as a rich source of electricity.

Cost of solar Panels:

Installation cost of the solar panel is depends on the system and requirement you want in term of consumption of your electricity at home. According to the United States survey the cost of solar system ranges from $11,144 to $14,696 after the solar tax credits. It will cost you per Watt energy cost of $2.51 to $3.31.

 

There are different prices according to the sizes some as are follows:

  • 2 kW after the tax credits in $4,381
  • 3 kW after the deduction of tax will be $6,571
  • 4 kW in $8,762
  • 5 kW available in $10,952
  • 6 kW in $13,142
  • 7 kW in $15,333
  • 8 kW cost in $17,523
  • 10 kW price is $21,904

Installing of solar panels:

Installing a solar panel is the important and critical phase of the solar panel system utilization because if you don’t know about the protocols of installation then this system will not be able to provide you electricity. It required angles for the absorption of sunlight rays. You can use your roof as well as ground if you have the lawn capacity where the sunlight fully falls on the plates without any distortion. The basic instructions to set a solar panel are as follows:

  • Scaffolding Placement the initial step is to perfectly set the scaffolding for the safety of the installation solar panel on the roof.
  • Mount Setting for solar panel the second step follow up of scaffolding is the arrangements of mount which work as base for the solar plates, the whole mounting settlement is must be according to the sun angles ranges from 18 to 36 degrees in maximum utilization and storing sun rays.
  • Placing solar plates after the mounting structure settlement solar plates then placed on them by fixing the nuts and bolts making sure the stability from wind and rain destruction.
  • Connecting solar wiring the next step the electrical wiring you must be careful to close the home appliances before the connection and probably MC4 connectors are suitable for all solar panels.
  • Solar inverter it should be placed at the cool place where no danger of getting heat up and have the proper ventilation mechanism such as the utility rooms, garages and stores in indoor location where at outdoor it must kept away from sun or in shades.
  • Joining the inverter to the solar battery it is very useful step in order to store the energy and electricity for the time when sun comes out such as in cloudy conditions and raining seasons, so you must have a backup to be safe from this disaster.
  • Converter to consumer unit it is the ultimate step to provide the electricity to the consumer by connecting those inverters to the main supply. You can also check the performance of your system through the monitoring of system that how much it is producing ,whether on demand production or not.
  • Proper Starting the final stage for which whole system installs is the starting of the solar by on the switch and enjoys the solar energy producing electricity for life for free.

Advantages and disadvantages of solar panels:

As stated earlier about the solar panels and their installation, one thing is clear about the solar panels is very beneficial to use some of the benefits are given below:

  • It’s a renewable and you can say free source of energy
  • It is helpful in reducing the electricity bills or can make you able to sale the electricity to others
  • It has the diversified range of application you can produce for your home as well as power unit as grid station and do business of selling energy
  • It has the best advantage of low cost to maintain and caring
  • It can be the source of technology development in future because this energy has a great scope in future for serving the population.

Disadvantages:

  • It has the high initial cost
  • It highly depend on the weather or sun
  • It required the huge space
  • Storage for the electricity is costly

Return on Investment for solar panels:

This will tell you about the profit you get on the investment you made on the solar panels by estimating the initial cost dividing it by the yearly benefit you get from it. For example you made an investment of 20 thousand dollars on solar panel and you will save the benefit of 4 thousand dollars per year then your payback time on investment will be 5 years. If you look at the electricity bills price commercially then you come to know that with the solar technology if you are saving up to 2 to 2.5 thousand dollars on average you are getting the best in this business. On Average it will give you 10 to 30 percent payback benefits on your investment.
