Solar Energy

Solar Energy – A Major Cost Benefit

The Value of Solar Energy to the Homeowner

Today, solar energy is nothing to scoff at as the generation of electricity by the sun proves to be a major benefit to the homeowner. Not only do you save on your energy usage, you also add value to your home’s worth overall.

Solar Panel Design

Solar panels can amazingly convert solar power into electricity because they are made up of photovoltaic cells – photosensitive diodes that instantly convert the sun’s light into an electrical current. The cell layers contain a silicon layer that carries electrons or negatively-charged, unanchored particles for conversion. A bottom layer creates an imbalance between the two cell layers.panels used for solar energy

On and Off-grid Designs

As a result, activation from the sun causes electrons and photons in both layers to produce a circuit. From an inverter the current is directed to the circuitry inside the house. Solar systems or solar energy can be produced on or off an electrical grid. An off-gird system needs power for backup storage when modules in the system cannot capture enough of the sun’s light.

An Affordable Alternative

Possessing such a system in the household is the best way a homeowner can contribute to reducing the carbon footprint and keeping electricity costs low. One of the major benefits of using solar power is its affordability. Solar energy itself is free. The cost the homeowner pays is solely connected to the equipment that is needed for conversion.

A Practical Source of Energy

Again, solar power does not negatively impact the environment directly. The panels that are used do not emit pollutants or carcinogens into the air we breathe or the water we drink. Also, many items that are used on a regular basis can easily be powered by the sun. Lower power appliances and calculators both are examples of items that can be run by only using the light of the sun.

A Power Source that Will Never Run Out

Take into consideration too that the oil reserves in the world are only expected to last for another 40 years. Solar energy, on the other hand, is an infinite source of power. Energy from the sun will never run out.

One Disadvantage

Naturally, along with the benefits, you have to review the disadvantages. However, some of the negatives are outweighed by the benefits. For example, solar energy is only harnessed during the daytime. However, back-up power can be provided in the form of a generator and batteries.

Still the Best Alternative

All things considered, solar energy is still the best alternative source for current and future electrical use. Plus, the sun can produce other forms of energy, such as hydroelectricity and biomass materials, each of which are used for such energy needs as electricity and travel.

A Focus on Self-reliance

Solar energy is versatile as it can be used on and off the grid. A house can remain connected to a state electricity grid or can be powered by the sun alone. Because the cost for installing utility lines in remote areas can be exorbitant, solar energy is a practical solution for anyone who wants to live away from the city. City dwellers, as well, are electing to go off the grid so they can follow a more self-reliant way of life.

A Sustainable Source of Jobs

In addition, solar energy benefits the employee. Solar jobs are available in manufacturing, installation, monitoring and maintenance. Other areas that require “solar” professionals include research, development and design. Not only is solar energy a sustainable source of power, it is also a sustainable source of jobs.

Saving the Eco-systems

Eco-systems are saved as well as solar energy does not depend on the mining of raw materials. Therefore the destruction of lands and trees are not affected by harnessing energy in this way.

There’s Just No Getting Around It . . .

Any way you look at it, it seems clear that solar energy is as good for the homeowner as it is for the environment and economy.

    Produce enough energy from solar power that excess can be stored in some
    sort of batterie. Use batteries as the power source at night.

    I built a super insulated solar home in 1982 and tried to produce all my
    own energy and food organically.
    I am so ashamed I fell for that Marxist college brainwashing of eco doom.
    People who can do things are not supposed to be that stupid.

    non-orbital Solar-array… if we were to lock a large plant in a orbit
    around the sun instead of a planet then said plant would create 24/7 power!
    (doesn’t help the cost though sadly)

    Can we not just whack a rechargeable high-voltage battery onto a
    photovoltaic panel which would charge up until the sun is hidden by our
    planet or the clouds, at which point we would just be using the power from
    the battery?

  5. Undead Merc

    This may seem really stupid, and I feel it probably is but… Why not just
    hook up a series of car-batteries or specially designed batteries to gather
    up a charge during the day and be used during the night for our
    necessities? That seems way simpler than melting salt or splitting
    molecules of water to make fuel cells… And way cheaper

    Would solar energy be a good thing to invest in or make a business of? It
    seems like the future of technology and I think we’re headed that way and
    that’s a good thing

  7. Firas Subeh

    I have a question: While using solar panels to get solar energy, suddenly a
    shadow appears and blocks the sun light from the panel, does the day that
    is surrounding the atmosphere be considered as solar energy? i mean the
    solar panels only get the energy direct from the sun light or it can take
    from the ( during the day ) atmosphere?

    did you know that 99% of the power we produce and use in iceland comes from
    water and earth heat, less than 1% is from fossil fuels

  9. zolacnomiko

    When you mention non-solar sources of energy (nuclear and tidal) you forgot
    one…geothermal!

    So, it seems we know what our problem is. MONEY. Money and greed are
    stopping us from evolving as a specie. Who in the earth would leave their
    oil and natural gas business, for a clean, reproductive and extremely
    efficient way to produce electricity.

    Solar power is made expensive on purpose.

  11. Samuel Palomera

    Thank you man. I never knew about cpv and may be a solution for when my
    country runs out of oil. 

  12. Craig Mitchell

    So where does Sci-Show stand on the farce that is Thunderfoot vs Solar
    Roadways ? ? ? So you believe it’s equally a miss use of crowd funding or
    do you think it’s a fair use of an idea to at least make available to
    develop upon ?

  13. Peter Martinson

    If you could not confuse power and energy in your science show, that would
    be great. (Insert picture of Lumberg here.)

  14. Dmaj87

    If solar panels was really really expensive to build, but there was no
    other option available for us. Would our excuse not to use it really be
    “sorry, we just can’t afford it”?
    We know how to do it, we have the materials to do it.. but.. we have a
    system here with pieces of paper that says we can’t do it. *facepalm* fail.

  15. NerfMC

    I love living in the pacific northwest where we get so much power from the
    Hydroelectric Power. Thanks Columbia River and Glaciers.

  16. Djefferson Djuan

    0:38 Watts is unit of power.. and the net influx of solar radiation to the
    Earth’s surface is about 270 Watts/m² so in a year your 1.5m² body would
    collect 0.5*1.5*365*24*60*60*270 joules of energy = 6.6Giga Joules per year
    (assuming the sun shines 50% of the time).. I am confused how you got your
    number

  17. Et3rnalPhoenix

    So in order to meet up with the worlds energy demands we must wipe out the
    species living in the hottest deserts and cover the sand with super durable
    solar panels.

    +SciShow , I’m a little disappointed: your example at 0:37 into the video
    is incorrect. First of all, watts are units of power, not energy. Second of
    all, the Earth receives about 1400 watts of power per unit meter squared
    when the area of interest in perpendicular to the incident light (when it
    is not perpendicularly incident, the power is reduced). Now for argument’s
    sake, an equatorial square meter will get about 3 equivalent hours per day
    of direct solar radiation due to the Earth’s rotation. Thus, a 1.5 square
    meter piece of area pointed at zenith on the equator will receive about:

    1.5 square meters * 1400 Watts per square meter * 3 hours per day * 365
    days per year = 2300 kilowatt hours per year

    This estimation is of course ignoring all weather effects, and the 1.5
    square meters is stationary always pointed directly up (at zenith). It is
    also more than 1000 times larger than the number you listed (with incorrect
    units which I already pointed out)…

    Now maybe you meant to say that zenith pointing areas on the equator
    receive about 1000 watts per meter square when the sun is at zenith…the
    1.5 square meters would give your 1500 watts figure… but then you need to
    multiply the total time that the sun is equivalently at zenith, which is
    for about 1/8th of the total year (or about 3 hours per day). Thus the
    total energy could be expressed as ~ 1/8 * 1500 watt years.
