can I use solar pannel to recharge 12V motor battery and at the same time use battery to run 12v water motor?

I am taking motor in remote area no electricity available therefore I need to run the motor contineously for long time that is why I need help /better idea in this connecion. Thankings for your help/suggestion

What you are asking is the normal connection of a solar or wind system. Their purpose is to charge a battery bank. At the same time, you can remove power from the batteries to operate devices.
You need to create a power budget. There is only so much energy available. You can not expect to operate a pump which requires 5A of current continuously while the solar panel is capable of only 4A peak. 5A for a few minutes will be ok provided the solar panels are given adequate time to replace the charge in the batteries.
A small portable generator could be a better option.
I have a few links and diagrams on my wind generator project page. The system will eventually have an input for solar electric panels as well. Take a look…

The public should take pride in the fact that ‘their’ building they work in produces a ‘sum’ of solar energy, so why don’t skyscrapers utilize this energy?

I agree with you that this should be done. As lawyerslastbreath saw in Las Vegas, those casinos have the $$money and should use it for solar panels…..If they can’t afford it who can?

Serious discussion here.

How feasible is the idea of communities, towns, even whole cities being powered by solar energy? At the most, how about these communities being fractionally powered by solar energy; 40% Solar/ 60% Fossil fuels?

We’re not getting all George Jetson, here. We have practical means by which to make something like this happen. My research has lead me to believe the problem comes in with the initial setup.

If this is so, what would it take to materialize the dollars? Should each State solicit a ‘solar energy’ tax; money dedicated to fund R&D solutions for citizens? Is it something that can be solicited to big business in exchange for free plugins; Staples invests in a solar power grid in Downtown Los Angeles… and calls it ‘The Staples Power Center".

First of all, look for existing incentives from the federal and state government. Federally, there is a 30% tax credit and some states offer as much as $5.00 per Watt rebates. You can get more information here: http://www.desireusa.org

Secondly, there are some up and coming technologies that will offer better economics than PV panels in the near future. Check out http://www.infiniacorp.com/
http://www.sandia.gov and http://www.nrel.gov

Third, for the kind of project you describe, it really comes down to financing. This will be easiest if you are planning to build a new community. Find a lender (bank or government) that will allow home-buyers to roll the solar energy system into their mortgage. This practice, along with a healthy rebate, helped to make Japan the PV capital of the world a few years back.

On a larger scale, many states are enacting renewable portfolio standards which legally require utilities to generate a certain fraction of power from solar, wind or biomass. RPS programs are also described on the DSIRE website listed above.

It’s a bit more complicated than seeking advice from us, but these links should get you started in the right direction:

Good luck…

I think that that solar panel will give 17,777.78 W at standard voltage (110V in the US), which comes out to be about double of what a standard household uses, taking into account efficiency (decrease to 70%) and cloud cover, night, etc (decrease to 20%). But I might be completely wrong. I would like to hear from those who know more about these things.

So is it equivalent to 17,777.78 W at standard voltage (110V in the US)? Or am I just lost?
Never mind—power doesn’t change, current does.

I dont understand your 17,777.78 figure.

Anyway, a 400 wat panel is unlikely to b enough to power your home unless your power requirement is vry low.
Those on solar power (off grid) generally start by reducing their power consumption as much as possible, by cooking on gas, using low enrgy light bulbs, and certainly not using electricity for any form of heating.

We live off grid in southern Spain with 860 watts of panels and it meets our requiremnts.
You can calculate your plower requirements (and find other info) at the link below

i hoked up 4 little solar pannels and my mulit meter said it put out about 6.2v and then when i hoked up a little 5v motor it did not make it spin and i dont know what the problem is because it has 6v and it only needs 5v and it still is not working. if anyone could tell me the problem or if i am doing something wrong please tell me!

Your solar cells develop 6.2v with no load, and next to nothing with a substantial load because they have a high source impedance and cannot deliver significant amperage. The motor has a low impedance and the cells cannot deliver the amperage needed to make it operate.

I don’t understand how some people who for some reason jump to the conclusion that Sentry would destroy Superman.It boggles my mind when I read these opinions of Sentry fans.One thing that they keep forgetting is that Sentry is designed was based on Superman.Look at the S for example on his outfit and the whole cape thing.He is just like the others before him.Prime who had a Superman like symbol on his chest minus the big S in the crest then there’s Hyperion who was Marvels homage to Superman.Now Superman is pretty much the prototype of some of the great comic book heroes ever created.My point here is Sentry power is sun based(where do you think they got that idea?) and I know that he has other nifty powers too.Superman body absorbs solar energy.It’s what gives him his powers.Who’s to say that Sentry using his powers on Superman does’nt turn the man into a god like entity.Superman went in the sun and came out stronger.I think that Superman would survive and win.What do you think?

I totally agree with you on this.Supeman does have a chance against Sentry.There are Sentry fans who call him Superman 1 million which is really crazy to me.The guy is’nt even Superman nor will he ever replace Superman as the number 1 iconic comic book legend in the world.Because of Superman we now have some great cartoon creations out there like some of my favorites Mighty Mouse,Underdog and many others out there.Even the Sentry creators nodded their caps to Superman by his costume creation design.I mean adding the S.I guess some people just don’t respect the classic comic book heroes anymore.There was an era where Superman dominated the market when he first appeared.Many people loved him.The first popular super hero with amazing powers.But I guess everyone has their own opinions.Imitation is a form of flattery as they say.This is why people look up to the great ones for inspirations and be as good as their hero.Superman represents the clean cut and straight and arrow hero who fights for "truth and justice".While others may try and be like him there will always be one Superman.Able to leap tall buildings in a single bound and faster than a speeding bullet.Putting others before himself.He never gives up.This is the character of Superman.

Solar energy is the best energy in my view .With the help of this solar energy we can use solar cookers,solar lamps,solar geasers
solar heaters, solar refregirators etc

Here are three of many sites you can find if you just do a web search.

After you do a bit of research, you will find that the cost for a solar system will take about 9 or 10 years for you to save enough money to pay for the system. By then it will probably need to be replaced. Not a very economic deal.

Windmills are out in the open spaces and very high. Could we not wrap solar panels around them to create even more energy ?

Sure we/you COULD… however, what is the point? The area of the ground below is more efficiently covered with solar electrical panels than the body of a tower with a wind powered generator on top. There is NO point in using the smaller area of the top of a tower than simple plain open space at ground level… Besides, when you do the daily/weekly cleaning to remove dust, it is MUCH more practical to clean panels at ground level than a hundred feet in the air… Note that wind towers are FAR apart to reduce turbulence from one tower causing problems with the air flow of the next tower. Haven’t you wondered WHY wind towers are hundreds of feet tall and hundreds of feet apart? You would better use the flat space BETWEEN the towers than the actual towers themselves… Use some common sense already!
