Solar/wind power for homes?

Admin — Sat, 19 Jun 2010 05:01:27 +0000

Is there such thing as a solar panel that also has a wind turbine system attached for homes? (Kind of a duel system that looks like a solar panel but has the turbines on the actual panel)

What kind of power resistor do I need?

Admin — Fri, 18 Jun 2010 11:54:39 +0000

I’m an 8th grader doing a science project using photovoltaic solar panels. I need 5 resistors, but I have no clue what kind I need! The solar panels are small thin flexible ones that say 3.6V (I think that’s the maximum amount of volts it can get…) But I need to be able to track the amount the solar panel gains each day, and I read that I need a power resistor and a digital multimeter. Could someone please help me find these 2 items?

Any help is greatly appreciated.

Thanks! =]

Save {Money|Cash|Dollars}, {Energy|Power} And The {Planet|Earth} With Solar {Panels|Power} And Grid Tie Inverters

We have to all be mindful of the necessity to save energy, even if it is solely to save ourselves money.

One plan could be using alternative energy, to this aim I want to advance solar”>http://www.solarpanelssites.com”>solar panels with a grid tie inverter.

The electricity made by the solar panel of about 20 volts can be from any additional renewable resource such as hydropower electricity.

Saving cash in the home means this generated voltage has to be changed to the customary house power level.

The DC from the solar panel is changed by the grid tie inverter into the AC that is used in the home.

The grid tie inverter is designed so that it does not require special boxes to join to the mains, but simply needs to be plugged into a wall socket. The electronics in the circuits of the inverter make the join safely.

Using the grid tie inverter and a solar panel will give the home electricity all the time the sun shines, this would have had to be bought from the power company.

Because current can only flow when the house power in on the grid tie inverter has a built in safety element. If the power fails, electricity could be fed back to the power company endangering the work men. But if the power fails the grid tie disconnects.

To supply more power to the home, additional solar panels can be used, along with added grid ties. Any surplus power supplied to the home can make the meter run in reverse saving you money.

This is a straight forward and efficient system to install, cost effective and will save cash in the long run. The alternate is to use batteries and a conventional power inverter to create electricity for the home, this has the advantage of night time power, but the extra cost and room needed for the batteries, makes this cumbersome in comparability.

The grid”>http://www.solarpanelssites.com”>grid tie may be the most efficient way to save money, you cannot replace the power company, but it is greener.

why does green light no give me a good power output for a solar panel compared to red and blue?

i carried out an experiment using different coloured solutions to see the affect of wavelength on power output from a silicon photovoltaic solar panel. I was expecting to see a peak where the efficiency of the wavelength and the energy of the photons were optimum. However instead i found that from wavelength in the blue region it was a fairly high power output which then decreased towards the green region and then increased even higher in the red region. I have made sure i kept the intensities of the different wavelengths constant. What could be the cause for this dip in the green wavelength region?

When will solar and wind power be affordable to the average home owner?

I have been doing some research on solar panel and wind turbine systems. The pricing is crazy. For a 10Kw solar grid tie kit system is between ,000 and ,000. If you install batteries add ,000-,000. 10Kw will only power a small to medium home without electric heat. Using my electric usage and info from my local electric company payback is 60 years for solar and 361 years for wind. This is unexceptionable. The manufactures of the solar and wind are gouging the consumers. They are using the excuse of supply and demand for the high cost. When demand goes up so will mass production and the price will go down. This is true, but they are making a huge profit on what they are making now. Some items are in the 3000% markup range. Are the power companies keeping the price up so their profits don’t suffer? My local electric supplier has an "ENERGY PARK" that you can go see solar and wind power in action and check out real time data online. They have a 4Kw solar array installed and claim it cost ,378 installed and a 2.5Kw wind turbine that cost about ,000 installed. I think they are giving false numbers to consumers so you won’t go green. I was able to find a 3.5Kw kit online for ,000. This doesn’t include any type of mounting materials. You can add 0-,200 for these materials. An installer will will charge you ,000-,000 to install it. For the sake of argument lets say this will cost you ,000 to install but still way out of line for you and me to install. That is a far cry from the ,000 the power company claims. The power companies don’t want you to make your own electric. They are keeping the cost high so they will still make money off you. A 210w panel sells for around 0. They probably manufacture it for under . The cost needs to be 0-0 to the consumer to make it affordable to the average home owner. 50 210w panels make a 10Kw system. That would be ,000 not ,000. The manufactures are raping us and the power companies are helping them to keep prices high. When will we get the technology at a proper cost? Let me know what you think.
In response to the first 5 answers, Yes, if demand increases so will mass production and thus supply will increase and this will drive the price down. I looked into panels from China. From what I was able to find panels sell for {content}.17-{content}.45 per watt. In the U.S. they sell for .00-.00 per watt. Manufactures in the U.S. have lobbied for a higher tariff on solar products that makes them impractical to import on mass. These companies want to keep the price high so their profits stay high, and the power companies do not want you to produce all your own power. That would put them out of business.
In response to Steve R, You need to do more research before you post another retarded comment like that. Air "DOES" have mass (just not very dense). When air is in motion it is called "WIND". This motion creates energy. Have you ever heard of a "tornado"? Get your facts together next time.

Solar Panels – Why Should I Install Them On My Home?

Solar Panel Review

We hear about solar energy in the news almost every day. Does it make you think about whether installing solar panels is right for your home? Here are a few of the most compelling reasons to consider it.

How To Make A Solar Panel Now

The state of ecomonic affairs is finally favorable again for people who want to utilize solar energy at home. There are now federal tax credits established (or soon to be) that can lower the cost of installing a residential solar energy system by as much as 30%. And don’t forget to check into your state and city incentives, as well. The list of government entities that offer tax credit and other incentives to help people convert to solar energy is continuing to expand.

There is also the immediate cost savings you will see in lower monthly utility bills. Since your solar panels will be running your appliances during the day, you will be seeing a savings in electricity usage. And if your utility company participates in net metering, it’s possible that you could pay nothing for your electricity. While your solar panels are functioning, they may generate more electricity than you actually use. Net metering allows you to sell back that excess electricity to your power company for a credit to your account. So if your solar electric system generates a surplus during the day, the electricity used from the grid at night could actually be free.

An Easy Step-By-Step Approach on How To Make A Solar Panel

Solar energy can also be of great benefit to the environment. It is produced in the same place where it is used, so there are no fuel transportation costs or emissions, and no plant maintenance costs. Using solar energy can help prevent global warming. There is no pollution from burning oil or coal, and it does not result in nuclear waste that will contaminate the planet for years and years. And last but not least, it is a great way to protect yourself and your family against the future energy price increases that experts are forecasting.

The future of this planet is of the utmost concern to many environmentalists. Solar energy now plays a key part of the methods being developed to curb the greenhouse effect around the world. It’s not necessary to wait for either the government or the energy companies to advise on this type of measures. Why wait! Find out for yourself the most economical way of installing solar panels to provide for your domestic energy supply. Before you start with your project do the research, as failing this step can prove to be costly later.

How can I use Solar Power in my home?

Admin — Wed, 19 May 2010 09:14:05 +0000

I am wanting to power just a couple household items with a small solar panel. What will I need? I know I need a solar panel, and some kind of AC-DC converter, and a battery perhaps? How would I wire it up?

I do NOT want to spend a fortune doing this, I am only in an apartment, so it needs to be small and self-contained.

Thanks!

Solar Power Projects Should Meet Energy Needs and Protect the Earth’s Fragile Biosphere

solarblogger — Mon, 03 May 2010 19:35:46 +0000

With more than a few billion people inhabiting the earth the need to find enough power to meet the changing and growing needs of this huge population calls for some very serious effort. With more and more emphasis being placed on the Western model of living it is not surprising that energy needs are not only required in greater numbers, but it is also depleting the already limited resources available to man.

Space – The Final Frontier May Hold the Answer for Future Needs

Space solar power projects may be the answer to providing humanity with energy that at the moment is in abundance in space. What will happen in the distant future is anybody’s guess, but it does present an environmentally friendly and economical energy resource at the moment. It should also give occasion to promote better technologies and will certainly further the prospects of future space settlement by humans.

The space solar power project is not such a novel idea as it has been studied from as far back as 1881 when the Nikola Test attempted to show that long-distance wireless power transmission over the earth’s surface was indeed feasible. Given the fact that space abounds with energy, it is only a question of time and considerable concerted effort before space solar power projects become reality.

The fundamental principal driving space solar power projects would involve satellites positioned in geosynchronous orbit that could collect the sun’s energy and convert it into radio waves that could be beamed to an earth based receiving site. On the ground, an antenna could then convert the radio waves back into electricity to power our energy needs.

At present, such concepts in space solar power projects are being aired and the aim is to reach out to the environmental community to disseminate information on space solar power projects and provide an opportunity to discuss its various pros and cons. It should certainly throw up many interesting proposals that would allow mankind to find an alternate as well as abundant energy source to meet the present needs as well as those of the future.

On the ground, at present, the U.S. Department of Energy has a Million Solar Roofs Initiative that is ambitious as also feasible that should meet America’s long term energy needs, and it is proposed that solar energy systems to the tune of one million should be installed in buildings across the United States by the end of this decade.

There is thus reason to be optimistic about future solar power projects being able to cope with energy requirements, and with space based projects, they should also help to preserve the earth’s fragile biosphere.

Peopls from different places signed for protect the earth, and they will start to install solar panel on the garden so that they can use it for solar water heating for their house.

A Few Helpful Tips On Solar Power Sizing

solarblogger — Mon, 26 Apr 2010 00:02:54 +0000

Before one decides on having solar power to run one’s home, one need to know the design most suitable as well as the proper solar power sizing that will fit in with general requirements. It will involve answering how much energy one has at one’s disposal, how much energy will be used, what efficiency would be required in using it as well as knowing the estimated costs of running the solar power unit.

Ascertain How Much Power Energy is Available

To ascertain the solar power energy available, one need to know how many peak hours of sunlight is available, which can vary according to the season of the year. In order to ascertain the solar power sizing that would ideally suit individual needs, one would need to know how much average power is to be consumed on a daily basis. This means knowing how many lights will be on as well as the duration they would be used as also knowing how many hours other items will be used.

Getting the correct amount of projected usage is important as it will save on inflated costs later on. In addition, one would also need to know how efficient would be the energy usage as it will play an important role in solar power sizing, and requires knowing what appliances and lights will be used, and which use more power than others. Switching to compact fluorescent lights and using them instead of incandescent lights is a good efficiency measure that will reduce power requirements.

Another feature worth considering in relation to solar power sizing is using a passive solar design which will help keep the house warm in winter and cool in the summer, and thus contribute to reducing energy needs all year round. Obviously, the most important consideration relating to solar power sizing is how much the cost will be. This means ascertaining exactly how much energy is needed and using energy efficient appliances instead of those that use too much energy.

Once one draws up a chart that contains the different appliances that will use up solar power and multiplies them with their estimated number of hours used per week, one will be able to arrive at their estimated average usage of watts per hour/week that can then be totaled to arrive at total energy consumption per day (by dividing their total watt hours per week by 7). With figures that show how much energy is required on a daily and weekly basis it should be simple to find the solar power sizing that will best suit these needs. Of course, the cost of the solar power system will also play an important role in the final solar power sizing module that should be affordable enough to install.

when you make landscape design, you can talk with designer to install some solar panel so that you can use the clean energy for your bathrooms,kitchens.
