Looking to purchase a Generator – solar/battery powered, preferably a combination – plug-in backup power.?

I am looking for a self-recharging, always PLUGGED-IN BACKUP POWER (quiet running) GENERATOR. Automatically kicks on when power goes out and shuts off on return. A combination of solar/battery cells is preferrable but would consider alternatives if available. It is to be used in africa, the electricity is 220V. Also, the cost should not be prohibitive. Thanks in advance.

this company has what you want

what type of solar pannel is required for it and what other accessories are required. (i dont want to use battery)is it maintenence fain the current output will be dc or ac please explain

You need a large solar panel and a small fan with a universal motor. Solar panels output DC. Universal motors are so named because they run on both AC and DC. The fan’s rated voltage must match the rated output voltage of the solar panel. You will also need a switch to disconnect the fan when the output of the solar panel drops below the rated voltage of the fan, preferably one that will connect manually and disconnect automatically.

Search solar panel manufacturers and you will find many suppliers. Also try suppliers of camping gear.

for science i need facts about solar energy all together i need 60 but i have 10 and today or tomorrow i need 20 thanks

Given that I assigned this paper and will probably see these answers, remember that you must cite your resources and yahoo answers isn’t a credible source.

Mr. Parks

I just want other peoples opinions because I can’t think of any reason why it would be better.

Advantages:
1. Capacity. It can produce any amount of power. All sizes are available. Increase or decrease of power production is instantaneous.
2. Area required/ Mw is very much less compared with the other 2.
3. Not dependant on weather.
4. Clean energy like the other two.
5. Continuous supply unlike the others which are intermittent depending of wind velocity or cloud cover, day or night etc.
6. Can be located anywhere. So not unsightly.
7. Pay back period for the investment is low at today’s cost. Not because the cost of installation is low but the power production is very high.
8. Nuclear fuel is available and hence it is not going to be in short supply any time now.
In every way nuclear power is the most advantageous, but the safety of operation and the perception that accidents can happen (caused by Chernobyl) and the consequence’s are far reaching is keeping the growth under check.

Well, I am looking for a cheap way on building a solar panel, instead of buying by the manufacturing stores. I would like to stay in the budget up to 1,000 dollars. I want to have Solar Energy for my house because the sun is always shining. Is there a way I can make the Light power some of my house? What would I need? How much time would it take?
Where can I get the items I need?

You have a couple of options.

The first option is to put together a flat plate collector to generate hot water. If you live in a cold climate, you might have to use evacuated tubes and this will probably blow your budget. The hot water could be used as a pre-heater for your existing hot water system. Complete systems for domestic hot water will not likely fit into your budget.

The second option is a small solar panel to generate electricity. In order to fit into you thousand dollar budget, you will need something like this:
1) an 80W panel. This will set you back about $400. You can’t make the solar cells yourself, so it is just as well to buy a complete panel.

2) A small solar charge controller for about $100. This will take the power from the panel and make sure your storage battery is properly charged.

3) An inverter. This will take power from the battery and generate 120 volt AC power (like your wall sockets). A 120W unit will be less than $200.

4) A 12 volt deep cycle battery, perhaps $120.

5) A transfer switch to cut the power when the battery gets discharged and transfer to 120 volt utility power.

You should be able to put it all together for $1000. However, you need to treat this as a hobby. The power you will generate is worth less than $10 a year, and is about enough to power a DSL modem and router (i.e. your internet connection). If it lasts 25 years, your investment (or loss in this case) will be about minus 9%. Of course, the battery won’t last that long, but the other parts could.

The actual power you can generate can be estimated from solar insolation maps. I will post a link below to a few that might help.

Collecting heat is probably more valuable (e.g. using a heat collector rather than a photovoltaic collector for electricity).

You can probably find plans on the internet for do-it-yourself flat plat collectors using plumbing parts, and electronic circuit diagrams for things like solar charge controllers, but I think this will be too complicated for your first project unless you really like tinkering. Buying components and integrating them yourself (figuring out how that get everything interconnected) will be loads of work for you first project.

Don’t be discouraged by the economics. You will learn countless things in the process and knowledge is always a good thing. Someday as prices come down on silicon cells (perhaps a new thin film technology) and evacuated tubes are made by the hundreds of millions you will be able to use your skills to make a much larger and cost effective system.

Have fun.

One of the best option for Green Power.
Following Item you need for Household solar power generator
Solar Panel to take solar energy
Battery to Store Solar Energy
Inverter to supply stored power
Controllar to mantain and check power supply.
According to your need you can have Solar Panel and Other Items.

Im wanting to do this to save money….. I don’t really want to spent 50+ on a book that might or might not work.

Most are e-books that cost about $50. They claim you can power your house from a panel that costs you $200. to make. I seriously doubt that it will generate much power. Certainly not enough to power a whole house. There are sites that show you how to make a panel. Just google them.Here is one for a solar thermal panel:http://www.thesietch.org/projects/solarthermalpanel2/index.htm
Here’s a plan that costs $12.95 to download:http://www.goodideacreative.com/solarpanel.html

Hope this helps.

I have to make a tv commercial is school encouraging people to use solar power.

so i need facts
the suns energy can light up the entire planet 100 times over (Not true but i want that kind of thing)
or how its not damaging the enviroment or something

Every hour the sun shines, a small handful of quarters falls on your roof. That’s the equivalent heat and/or electricity you could harvest. It’s raining quarters!

We have an average size solar array. Symbolically speaking, every hour when the sun is strong, one or two quarters drop off the roof, and rolls into a can. Not much. But the stream never stops. Every once in a while, I go and check the can, and see how much is in it. $600 a year.

"Ow! What was that?"
"Oh, just another quarter falling off my roof."

only advantages are not burning fossil fuels and creating less pollution.

A solar panel can generate 70 milliwatts per square inch * 5 hours = 350 milliwatt hours per day. You need about 41,000 square inches of solar panel to power a house. That’s a solar panel that measures about 285 square feet (about 26 square meters). That would cost around $16,000 right now. Then, because the sun only shines part of the time, you would need to purchase a battery bank, an inverter, etc., and that often doubles the cost of the installation.
100 watts per hour purchased from the power grid would only cost about 24 cents a day right now, or $91 a year. That’s why you don’t see many solar houses unless they are in very remote locations. When it only costs about $100 a year to purchase power from the grid, it is hard to justify spending thousands of dollars on a solar system.

solar panels are expensive until the cost comes down it’s will remain an exception more than a rule. the same applies to hybrid cars because of the high cost & weight of the batteries. They are working on these problems but so far have not found a low cost way to make them.

How much money does it need to build SOLAR PANEL (solar energy system)?
I read this article on good things about solar energy.
and it said ‘Solar panel construction has advanced significantly in the last 20 years and can withstand almost any weather condition. It is not even that expensive since technology has advanced so much that panel cost has been reduced significantly.’

So i was wondering how much does it actually cost now thnxxx

It depends.
A small one is $10 and one to keep a big house supplied with power can be more than $50000
