Solar Power Home Electricity – A System on the Frontier of Renewable Energy

A Look to the Future in Home Renewable Energy


There is no denying that for the past 110 years, electricity has been the key in providing the resources for the comprehensive developments and advancement achieved by mankind. Now, we look for systems that push forward renewable energy.
Solar power home produced electricity is one energy source system.
Look all around us, and you will see that there are new technologies and inventions being developed with a dependence upon electricity. In addition, as the expansion of the world’s economy amplifies so does the huge requirement for electricity. This massive demand is being met by hydroelectric generators, nuclear stations, solar farms, wind systems and other conventional methods of producing electricity.
Electricity producing methods of fossil fuels like coal and oil so far have given us the basic assets to create electricity with the use of steam turbine generators in utility power facilities. However, these techniques have been confirmed to be dangerous to the living ecosystems on earth, and have been mathematically shown to be a limited source of energy. In other words, fossil fuels for generating electricity are not renewable.
You would have to agree, in our present world, we cannot live without electricity. Our demand for electricity power is increasing almost daily and we clamor that new research which will lead us to the creation and expansion of safer and cleaner energy sources. Just as mentioned earlier, solar power home produced electricity is one valuable energy source system.
Basically, in use today for harnessing solar power energy, the two methods of employing solar electricity systems are indirect and direct.

Direct methods:
  • use photovoltaic cells, termed solar cells
  •  made from wafer-thin slices of crystalline gallium arsenide, silicon, or other semiconductor materials which transfers solar radiation into a flow of electrons or electricity
  • solar cells connected in large numbers into clear anodized aluminum alloy and glass flat panels (often 5’L X 2’W X 2”Deep)
  • modern advancement of solar photovoltaic power cell panels has reduced cost of electricity to 20 – 30 cents per kilowatt-hour
  • solar technology has been used from the beginning of space exploration to provide electricity energy to satellites both that orbit the earth and travel out into far deep space.
  • solar electricity systems provide a long term and sustainable energy resource because there are no moving mechanical parts
  • solar cells have relatively low efficiency rating
  • solar power panels are dependent on the time of day, weather conditions and often seasonal changes
  • solar electricity systems need to have a inverter to switch the DC voltage into AC current in order to be consumed in commercial enterprises and in homes
Indirect methods:
    • concentrates solar radiation into a focus so that the energy heats to boiling liquids (often water) which in turn drives turbines to rotate in magnetic field and produces electricity
    • employment of a parabolic trough that is made up of a linear parabolic reflector to concentrate solar energy into a receptor positioned on a focal line from the receiver; then, tubing connected to the turbine filled with liquid that takes in the heat generated through the application of the solar energy
    • this type of solar electricity generating systems has a higher efficiency because the sun’s radiation is focally utilized
    • other developed technologies extend the indirect power generating efficiency rating by using solar energy towers along with sun reflecting dishes

We have realized through experience that even though fossil fuels are power producing beneficial, they are used with long-term negative consequences.
These realizations of negative outcomes have moved us towards a trend of renewable, non-pollutant sustainable energy to help guarantee life on earth is continued.
Plant life has used solar energy since time immemorial, so why can’t we as intelligent human beings harness this solar power without negative consequences.
In many popular opinions, the big energy companies seem to be holding back progress, and in the intervening period, also are digging up the earth and polluting the oceans. It’s up all earthlings to start looking to the heavens.
Solar power and wind generated electricity systems provide the methods to achieve the goal of sustainable living.

3 Important Phases to Solar Power Home Panel Installation

In the process of transforming your home into a renewable and sustainable solar power structure, there are three key and important phases.

  • 1st phase - Pre-installation Decisions

  • 2nd Phase - the actual physical Installation of solar panels, wiring and assembling of the connection of batteries

  • 3rd Phase - Post-Installation Follow-up

Pre-Installation Phase #1 points are:

If you wish to achieve the maximum effectiveness of your time, money and energy, there are 7 important factors involved in the 1st Pre-Installation Phase. These factors are pretty much all equally vital to the overall success of your transformation to a self-sufficient solar power home. A critical mistake in the initial phase could cost you considerably in the long-run.
  • your budget parameters - how much can you afford to spend
  • Gather all the necessary materials - have them trucked in and accounted for
  • Get all equipment and tools handy - everything you will need to make a rapid and proper assembly
  • Calculate how many solar panels are needed to power your household. There are several sources of data and charts to help you with your calculations. Remember - you will also need sufficient batteries in which to store the solar power that you have converted into electricity.
  • Consider all the community, sub-division, city and state regulations and rules for your solar power project. Prior planning will definitely be of benefit, because you do not want to be halted in mid-project.
  • Decide whether you will purchase panels from a reputable dealer, take a chance through Ebay or other online resource, or even build them yourself. There are guides available that will walk you through the process.
  • Just like mentioned above, have a manual or installation guide close at hand to show the installation procedures of the solar power panels

Phase 2 - the physical Installation of your solar panels

  • Use laser, a tight string or chalk line to ensure straight maximum sun exposure. Check the Internet solar resources to help your set it up so your solar panels are installed in such a way to track the position of the sun in the sky over a year's time.
  • Using a stud finder or similar device, locate the rafters in your roof and drill your holes.
  • Next, attach and secure the solar panel mounts
  • Then, place the panels on the mounted rails and screw in firmly
  • Wire the electric circuits of the panels together and connect them to the inverter

Phase 3 - the Post Installation

  • Congratulate yourself on the completion of your solar panel installation
  • Make sure your Home insurance properly covers your new investment
  • Make a maintenance note - after every major storm, inspect your solar power system to make sure that it is still intact and working efficiently
  • File for all your tax rebates and grants
  • Enjoy… your lower utility bill every month
  • Invite all your friends and neighbors. Have a Solar Power Party!
