The Best Green Energy Systems are Solar Panels

Solar panels are made up of an array of solar cells. Each solar cell works by releasing an electron whenever the sunlight is absorbed. Solar cells are also called photovoltaic cells. They are made from silicon semiconductors. Solar cells work by causing electrons to flow in one particular direction. The electron flow is normally directed out of the solar panel towards the batteries or the appliances. The solar panel system is one of the best green energy systems.

The main components of a solar panel system are:

  • Solar Panel: consist of an array of solar cells
  • Inverter: This converts the energy flow from DC to AC for use with AC appliances or batteries
  • Batteries: Stores the energy
  • Charge Controller: regulates the directional flow of the electrons

The benefits of solar energy compared to other conventional and green energy systems are vast. Solar energy systems have zero emissions. It is a sustainable and renewable energy system. Solar panels are set and play technology, meaning that it requires very little maintenance. Solar cells work as non-moving parts which do not decay. There is also no emissions or noises. The impact on the environment is practically zero.

Another advantage of solar panel systems is the rebates or tax credits that government and utility companies now provide. There is also the possibility of selling excess green energy to the power distributors via the power lines.

The cost of owning a solar panel system all boils down to a one time initial investment. The cost of maintaining a solar system may only occur every five years or so and depends on the quality of the components that were bought in the first place. Remember that green energy systems are long term investments. The size and components of the solar panel needed has to be calculated first before buying a solar panel. The appliances and KWH used has to be taken into consideration.

The average American home uses 958 KWH per month. This would require 100 sq. ft. of solar panels. The cost of owning all the necessary components including installation would approximately be around $10,000 to secure 958 KWH per month . It should be easy to setup this renewable energy system. This would have a payback period of 10 years, after that your green energy system is practically free.

Oh gosh Rasta1-

While I certainly agree that solar photovoltaic (PV) panels are reasonably included in any comprehensive enegy portfolio, it is very difficult to call them the "best". All energy sources must be weighed and compared as a "all-in" cost which includes: reliability, mining and transportation, conservation of natural resources, location, pollutions, ownership (think foreign oil), performance over time and many others.

Unfortunately, several of your assertions are in error.

For example, 1 KWH (killowatt hour) is the amount of energy a single 100 watt bulb uses in 10 hours.

Most houses will use the output of about 5 KW (kilowatts) of solar panels that will generate (depending on location) between 6,000 - 7,000 KWH a year.

Solar panels do degrade over time, approximately 1/2 to 1 per cent a year.

Batteries are typically not used on residential systems that are grid-tied (and nearly all such systems are grid tied).

For a reasonable term payback on a solar PV system, the owner would have to be able to make use of the federal investment tax credit (ITC) and depreciation (both requiring a tax appetite), along with the rebates, refunds, value of the energy,and the renewable energy credits (REC).

Very useful hub Rasta! The solar panels pay for themselves in the long run, I'd like to have them in Orlando...one day. Hopefully. Our inground pool has solar heating which is a good start. UP! Awesome!

Respect Win, I'll say KWH per month instead of KWH.

Respect Sunshine, I am looking into off the grid systems for the future. The Oil system is slowly fading away.

OIL WILL NEVER fade away in your lifetime.i don't see airplanes, cars,plastic bottles,and a million other items made from oil.

The President in his recent press conference pointed out that the greedy oil companies made $377 billion in profit last year. Think about it, the oil companies pay 40% taxes on the profit. The US Treasury ( taxpayers ) should be thrilled for the windfall. What did Obama do with the money? Obama wants to take away the $4 billion in subsidies. Are you aware that when oil companies produce oil on FEDERAL LAND, the government receives addition money for the lease hold and RECEIVES a royalty of $18 a barrel besides the tax on PROFIT.

Today, the Alternate Energy industry is getting $9 billion in subsidies from the federal government. The government investments are going broke costing the taxpayers $billions. Seriously who would you invest in, a loser or a big winner.

You are right Jon Ewall, Governments do love oil. Alternative energy resources are not getting any love. Oil is a much more easier resource to tax given its tangibility. Alternative energy is very hard to tax and could end up a big player in the black market. Thanks for an alternate view on the issue.

Keep pounding this drum. All we need now are better batteries. I just read where a man claims to be able to make one that uses some kind of composite metal rods in plain old beach sand (silica).

So called “third world” nations should avoid the pitfalls of a huge centralized power grid. It is too vulnerable to the weather. Local strategies make more sense. Your examples are a case in point. It amazes me that we have advanced so far with electronics, yet we still use the same antiquated electricity delivery system (poles and wires) that they used on day one. We should wean ourselves off as we apply a modular approach to our dwellings.

Peace!

Respect WD, I am starting to see a lot more wind turbines and solar panels in Jamaica. I am impressed given that there is no help from the government.

There are other sciences that can be used to generate electricity which which our generation is not aware of.

Respect Jon Ewall, I am aware of this situation, an oil crunch is inevitable in the future. People may have to park their cars in the future.

We should do all we can without the government. I remember president Kennedy's words, "Ask not what your country can do for you. Ask what you can do for your country."

Individuals can assume responsibility for their own needs with a modular approach.

Respect WD, it is time to be innovative and/or cut back on consumption.
