Which solar panel is most efficient and best price for my home?

Looking for the right solar panel for my home, what is the most efficient panels is best for me.
Kyocera?

You really need to look at your energy useage, that will give you an idea of the scale of your solar power instalation. I can save however that if you buy the parts and assemble them yourself you’ll be paying about $150 per 1000w output, compared to from $1,200 to $1,500 for the same wattage if you buy prefabricated units and have them installed. I recently did this, if interested you can check out http://www.earth4power.biz which is where I got my schematics. It also includes sources for the cheapest materials.

I wish you good luck, go for it. The energy savings far out does the initial start up cost quickly.

Should I buy stock in green energy?

I'm looking to make a long term investment. I just don't know of any big green energy companies yet. Could anyone tell me what a good company there is out there I could invest in?

why don't you buy stock in my didick…. it's on the rise :)

Where can I find information and parts for a small solar panel project to run air conditioning for my garage?

I live in Corpus Christi, Texas and would like a local supplier if possible.

How did the cycling of solar energy through the biosphere begin?

Photosynthesis and cellular respiration are the same chemical reactions headed in opposite directions. Photosynthesis takes carbon dioxide and water and produces carbohydrates and oxygen. Cellular respiration takes carbohydrates and oxygen and produces carbon dioxide and water. Respiration is the exothermic reaction. Photosynthesis requires the input of energy from the sun in order to proceed. In the economy of ecology, why are both reactions necessary? How did the cycling of solar energy through the biosphere begin? How can it be best maintained today?

–Please help me understand this alittle better.

First, to be precise, nobody actually knows for sure. We do not even know exactly when life, as distinct from non-living chemical activity, began. Prior to life on earth, the elemental chemical composition of the earth was constant, same as now, but the molecular chemical composition was different. There was likely no free oxygen, the predominant gaseous materials likely being water vapor, methane, and ammonia. Once the average earth surface temperature dropped below the boiling point of water, life as we know it became possible. It is believed that various solar energy and atmospheric effects caused complex chemicals to form in puddles at the boundary between land and sea, and that, over time, these puddles became the first primitive living cells. Initial metabolism would have to have been based on methane, ammonia, water, and carbonates from rocks. Eventually, early bacteria-like creatures changed the atmosphere into something more similar to the present one, and this enabled the development of sugar formation (CO2 plus H2O plus energy) with oxygen as a byproduct, and the metabolism of sugar (CH2OHx plus O2 yields energy) with oxygen to obtain energy and get back the CO2 and H2O. There is evidence that this process was well under way 2 billion years ago.

To be clear, neither photosynthesis nor cellular respiration are necessary in any cosmic sense - they are features of certain life forms that developed somehow on earth and exist to this day. Without these reactions, those life forms would not exist, but perhaps others could and would. In any case, the biosphere exists because there is solar energy, which has been irradiating the earth since the formation of the solar system. Life has developed the ability to trap solar energy and use it for plant growth, which in turn supports animal life, which closes the mass and energy loop by providing equal and opposite chemical activity. Every output from every living thing is available as input for other living things, and over time, life develops to exploit all thermodynamic opportunities, no matter how slim or rare. There is no scientific answer to "why"; these are just observed phenomena, which exist, period, whether we understand them or not, whether we can explain them or not, whether they help us out or not.

Now the big question -"how can the balance of oxidation-reduction best be maintained today?" The answer is for man not to engage in oxidation at a greater rate than he can engage in reduction. The burning of fossil fuel at the greatest possible rate has doubled the atmospheric CO2 percentage (from 0.04 to 0.08) in a century and a half, doubling infrared absorption by CO2, raising average surface temperatures a degree or two so far. Those fossil fuels were produced as life forms when the earth was much hotter due to much higher CO2 levels, and also sea level was higher. Fossilization fixed huge amounts of carbon that would otherwise have participated in the greenhouse effect - the earth has been cooler since, on average, than it otherwise would have been, with the resulting accumulation of land ice and the accompanying lowering of average sea level. However, if the greenhouse effects were eliminated completely, the earth would be too far from the sun to have any liquid water at all. It is the presence of CO2 and methane in the atmosphere, trapping the re-radiation of thermal energy derived from absorption of solar visible energy, that heats the surface of the earth enough for water to exist as a liquid and for life as we know it to be possible this far from the sun.

The bottom line is that all natural systems include reciprocal effects, whereas many man made systems do not, resulting in the buildup of some by product (pollution, garbage, CO2, etc.) All human systems must be arranged to recycle, period. Processes that cannot affordably be matched to a reverse process have to be eliminated - the burning of coal and oil for heat energy have to be eliminated because it is thermodynamically impossible to economically reverse combustion - burning is just too exothermic.

There are several "inexhaustible" sources of energy to be tapped - solar radiation, geothermal heat, nuclear fission, tidal flows, and the secondary effects of uneven solar radiation (wind and falling water.) There are technologies for all of these that are feasible now, and which would be cheap enough to compete with coal given sufficient economies of scale and sufficient "fossil fuel combustion taxes" to discourage coal burning. Note that "clean coal" from a global warming perspective cannot exist, given the exothermia of combustion and the impossibility of fixing the CO2 produced by burning at an equal opposite rate.

Answer your question?

Thinking green and was curious bout making a home made solar panel? can you help?

Was curious for reasons im not even sure why but i was wanting to find out all i can bout making a home made solar panel…

Just want to see if it'll work and for my own curiousity

What is the trade-off for so-called "Green" or "Clean" Energy Jobs? They say Spain has a 17% unemployment rate?

Because of the "Clean" or "Green" Energy jobs. If that is true, why does Obama tout Spain as a good example of these types of policies?

So called green, clean energy is very expensive.

The result is that more manufacturing jobs will go overseas. The result will be massive unemployment.

Massive unemployment will cause dramatic declines in incomes as employers are able to pay much lower wages to people desperate for any kind of job in an environment with enormous numbers of unemployed people.

At the same time incomes are collapsing, the cost of energy will increase dramatically.

It will cost far more for fuel for your car and it will cost far more to heat and cool your house.

If you did not like gasoline at $4.00 per gallon, you will really be unhappy with green biofuels at $10.00 per gallon or more.

This will bankrupt far more people and cause many more foreclosures.

We will become a desperately poor nation.

Life will become nasty, brutish and short.

Welcome to the so called "green" revolution.

What parts do I need to put together some solar panels and tie them into the grid?

I have a relatively small home, but space to work with on the roof and in the yard. obviously i know i need solar panels, but what parts do i need specifically (please dont just say "a kit") to tie it into the power grid so the power company pays me for the power i produce. Any brand name preferences would be welcome.

I did some searching for you and found this site.
There is more info on how to…..
Hope it helps!

Why is solar energy a renewable resource and also some advantages and disadvantages of using solar energy?

Please tell me some disadvantages and advantages of using solar energy. I also need to know why it is a renewable resource. Can you also tell me how much of of solar energy is left and how long it will last. Thank you so much. [Tell me some websites to vist about this information]

First, its all a guess but the sun will continue to shine for about another 2-4 billion years. So for all practical purposes, its eternal.
Solar energy depends on sunshine, one disadvantage is cloudy, overcast, rainy, snow etc. days. No sunshine, no real energy. Another difficulty is converting solar energy, solar panels generate direct current (DC) and this has to be converted to AC current to run appliances, etc. in your house. In order to store solar energy, batteries are required, so the DC current from the solar panels can charge the batteries, and then the DC current must be converted to AC.
Solar panels are not cheap but the price is coming down. They also don't last forever and can be damaged by hail, etc.
The good news is, solar energy is clean, not pollution except for the manufacture of the panels and for the moment, sunshine is still free.

A question regarding the home made solar panel?

Ok first of all, is it possible to extract silicon from silicon dioxide or silicone in a cheap way? Second of all even if I buy silicon is it possible to make it into a silicon solar panel. By the way I do posess some knowledge on the topic of solar panels and am not another naive kid who wants to know how to make a solar panel but does not have the means or the knowledge to do so.

It usually requires a lot of special equipment and chemicals to do this.

is there an easier way, sacrificing efficiency, to do it with less equipment? I don't know but I doubt it.

If I want to convert to green energy what is the best way to start?

Can anyone recommend any electricity suppliers who specialise in environmentally sound energy supply in Britian/Scotland? I am with scottish gas would this be considered a 'green' form of energy supply or can I do better?

Here's a great site to learn the basics from if you wish to generate some of your own electricity. (My personal favourite)
Help is available in the form of government grants towards the total costs of an installation, but you need to check your area/locality for the correct information: http://www.nef.org.uk/greenenergy/index.htm

For energy from a supplier, here's a comparison site:

All the best with your endeavour. It's a pity more people don't think similar.. :)
