what is the average cost of a solar energy system fully installed in a residential home?

The State Energy Conservation Office (SECO) of Texas has a useful calculator that can help you determine the costs and benefits of a solar energy system (link below). They've determined that: "Today, a reasonably priced PV system can supply a families' electricity if they use it efficiently, and if the electric grid isn't near, PV generated electricity may be the cheapest power source."

The Texas Solar Energy Society site has some good information. They're determination is that cost of energy generated from solar is still more expensive than buying "on the grid". (However, in 2006 the cost has risen to 14-16 cents/kWh in many cities.)

> "Compared to the current average price of electricity from a power plant (about 8 cents per kilowatt hour), PV electricity will cost you roughly twice as much, based on a 25 year lifetime.
The system will also appear expensive because you have to bear a large capital expense up front.
Generating enough electricity to power a home inherently takes a large collection area.
The most efficient way of utilizing PV, "grid attach", in which the electric utility buys back energy from you, and basically acts like a giant battery, is frequently discouraged by electric utilities (Austin is an exception). The fate of this "net metering" after deregulation is uncertain.
Batteries, used for energy storage, can be idiosyncratic and short lived, compared to the rest of the system.
As a way of displacing fossil fuel use (and pollution), it is less cost effective than basic conservation, passive solar techniques, and solar water heating. These should be considered first."

There are some Tax Credits:
The tax credits are for 30% of the cost of the system. For individuals the maximum credit is $2000 for photovoltaic systems and $2000 for solar water heating systems in any tax year.

Good luck! Sounds like an exciting project!

The How and Why of Solar Energy

More and more people are becoming conscious about the environment and going for natural energy options. Solar energy is one such option that is simple and economical. Learnt more how to use solar energy from the points mentioned below.

The solar panels located on the house roof capture sun rays. This sets off another panel located on the other side of the home which converts the electricity or current from direct to alternating. This leads to creating of electricity in all the outlets that are there in the house. In case the residents of the house fail to use it immediately, the current is stored for future use.

Using solar energy has benefits on two fronts – financial and environmental.

• Financial benefits are created through the reduction of energy bills. People can also garner credits from the local electrical authority. Using solar energy is also said to enhance the real estate value of a residence.

• Environmental benefits are created through the reduction of problems related to global warming. It also leads to conservation of fossil fuels. Pollution is also reduced leading to a cleaner air and water.

Ensure that you go through quality instructions while installing solar panels on your own. This will relieve you of stress and also make you feel pleasant about your DIY project. Internet is a good place to start searching for DIY manuals.

We have gone through several guides to present you a good way of building your very own solar panels for energy. Do not hesitate and acquaint yourselves with how to generate solar energy and reduce your energy bills.

Where do the DC currents go in a solar energy system?

I read that the currents pass through a regulator then it would go to either a DC load or a battery...
Where would the DC currents specifically go?..Do we need DC currents in some of the appliances??

If we need DC currents for some of the appliances, then how can we acquire them at night? Because when I look at the schematic diagram, only the AC currents comes from the battery.

I don't know if my question makes sense but I hope someone could help me out. Thanks.

Anything that has a "brick" plug uses DC. That brick is a step-down AC=>DC converter. Laptops, cellphones, iPods, game consoles all use DC.

Batteries always output DC, as well.

To solve your energy problem, charge the battery during day time, and use the energy at night time.

What functional role does an atmosphere, its life forms and evolution, provide in a Solar System (of Energy)?

To live and die perhaps....?
Just a thought, ....
It just seems strange that an atmosphere has emerged within this system.....
Is there a closer link between planets and suns that we haven't yet considered?

Well, I'm still not sure what you're asking, but let me narrate a bit and see if I stumble on what you wanted.

There is a systems theory. Systems move toward greater complexity and diversity. Therefore, you have rocks/minerals. They don't require much and don't do much energy conversion. At some point, we got some energy introduced into a mineral and chemical world that created more complex molecules. The molecules then take more resources. Eventually molecules that can take more resources thrive more. Somewhere in there, the system develops something novel like DNA which allows its molecules to take up more resources than the other molecules, and then we get cells and move on our way up the evolutionary ladder, always favoring systems that have a strategy for more efficient energy use, from humans who have intellect and history and technology to cockroaches that maximize fertility and speed and other factors to offset their relatively lower dexterity and intelligence.

The atmosphere comes about when somewhere in the evolution of a planet like ours, some mutant cell somewhere decides that fixing the plentiful (from volcanic eruptions, for example) carbon dioxide and water and using that as an energy source and producing sugar (stored energy) and oxygen. Then some other mutant cell decides that it would be neat to enter into a symbiotic relationship with the plant cells and use their sugar and oxygen to make more water and carbon dioxide for them.

The rest of your question sounds philosophical. I couldn't tell you how a solar system feels about having life forms and planets with atmospheres. Stars have a life cycle too that is independent of any orbiting planets for the most part. They burn hydrogen and then helium and then start to die out into various forms, depending on their initial size/mass.

I hope this helps.
