Hοw bіg wουld thе solar panel bе tο generate thаt amount οf energy? Thanks fοr уουr hеlр!! !
i thіnk u gеt аbουt 1 watt per square foot

- What do I attach my solar panel to so that I can read how much energy it was generated?
This is for my science fair project, I'm comparing the energy gained with Wind and Solar. I have a solar panel but it didn't come with anything but alligator clips. What is something I can buy that would tell me how much Energy the panel has harvested? I was thinking something like a 12 volt...
- How much energy can solar panel produce?
I am doing a project on solar panels.
All information given has to be accurate.
May I know how much energy can monocrystalline, polycrystalline, amorphous, vaporware solar panel produce? I also want to know more about solar panels. For example, how did Americans use solar panels during autumn and winter? Is the solar panel used...
- How would I run a light bulb off a solar panel?
I am looking to make a demonstration using a large amorphous solar panel that I have lying around. I want to keep this as simple as possible. The solar panel that I have is a 96 Watt 12V solar panel. Thanks for any help or suggestions you can give me.
Good for you...
- How to use solar panel to generate electricity?
Hi, I want to generate electricity using solar panel at home and I want to follow a simple tutorial.
Could you recommend me a good tutorial?
Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to...
- If I had a solar panel hooked into the electricity grid and there was a blackout during the day?
where would the electricity from the solar panel go?
would it just heat up the solar panel until it explodes?
That's a good question.
When a grid goes down,
and you're system is still supplying power to it,
it creates what is called "islanding."
http://en.wikipedia.org/wiki/Islanding
Very dangerous.
That's why inverters today are wired up
with automatic anti-islanding circuitry built into them.
It shuts down the...
- How can I connect a solar panel to a power outlet to help power my house?
I Have a small solar panel and Im not so sure about its voltage, so how can I connect it to some power outlet? And no; I am not thinking about using it to recharge batteries or directly powering appliances.
This is done through the use of a grid tie inverter. The inverter turns the...
- How would you connect a solar panel to a fan?
I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually "connect" the two together. Any help is appreciated.
Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the...
- How many watt solar panel do I need to charge a 12v battery that wont be using much electricity?
1. The 12v battery will only be turning a small 12v motor that will be turning very slowly yet possibly or a long time.
2. 1-2 hours max per day it will be running
3. I want it to be fully sufficient on solar power once the energy in the battery runs out.
What specifications for...
- How to make a solar panel for my house?
I want to learn how to make a solar panel to help lower my energy costs. Any recommendations on where I can start on my solar panel project? Thanks!
Yes, it is possible to learn how to make a solar panel for your house. I was skeptical with all these claims about making your own energy,...
- How to prevent shorting out solar panel?
I have a solar panel I bought for a diy project and it has a small plug on the end of it, but I need to remove this plug to expose the positive and return wires so I can solder a bunch of stuff together. How do I cut off the plug without shorting out...

They never fully pay themselves off.
I work for the largest energy maker on the east coast, sadly the gov’t mandates us to make "renewable" sources, which is dumb because all energy sources arwe renewable, contrair to what people are brainwashed into believing.
But energy panels have never once fully payed themselves off for us, even with the large gov’t grant we’re givin they still don’t pay off the part of the money we payed for them

Fact is, big and local governments might subsidize installations, but they’ve been running low on cash for these initiatives. The idea was better than reality.
Generating power from a free source is a nice idea, would even work if the polysilicates weren’ t so expensive. In the end, its agreed by the people that know what they are talking about and have experience with solar panels, the current price for them never offsets the total cost.
As for voltage, that would depend on how large the panel is. Most solar panels are actually made up of mini panels that are linked together in series to make a higher voltage unit.
You would have to check the specifications for the panel itself. That and with newer technologies coming out. Currently most of us use the thin film type, but there are new inventions not on the market yet that are suppose to be able to give more voltage out for the same amount of sun light. But these are still being experiemented with by small developmental companies.

i think u get about 1 watt per square foot

If it is green living you are looking for, and want a solar panel good enough for your home, then with the conventional methods you are just not going to succeed. The typical mistake people make is to use the obvious solar panels. Hence, they don’t succeed.
If you plan strategically and have enough sunlight in your area, then you can easily make a solar panel that pays off quickly.

High end solar panels generate 200 watts at 18 volts.
Households (USA) require 120 volts, so you would need 7 panels each at 18 volts, to match the energy usage of 200 watts at 120 volts.
The cost for 7 panels is about $6000.

i dont know the technicallity of them, but their is right now on my ceiling more than 15 solar panels that were installed around ten years ago as a sollution to high power bills in my country, i had to buy 16 deep cycle batteries and a bunch of expensive stuff, and we were then a family of about 5… by 2am the lights went out… we had to sleep in the dark after 2am, or the power would come on and of randomly… if you live on your own you might be ok.. but if a big family dont do it…
mine have been laying on my ceiling for almost a decade unused…

The Solar technology needed to power all appliances a big house is here now. Although it has been late in coming, if you do your research very well, you will find a modern solar installation that will give you more than the energy you need. Do not be discouraged nor listen to those to those who installed theirs many moons ago. The new technology will definitely work for you.

That’s not an easy question to answer.In short it depends on what type of panel. Second it depends on the size. Why someone would say that they never pay for themselves is just plain stupid. At what point does you fossil fuel generated electricity pay for itself?. In the US we have a 30% tax credit for Solar Thermal, and Photo-Voltaic systems. A typical PV system will pay for itself in about 10 years. The brainwashing referred to here is the company telling their employees that "solar doesn’t work". You have to ask yourself this. Who’s interest are the protecting?Now I’ll get down off of my soapbox and try to answer your question in another way. Photo-voltaic panels are tested and given an efficiency rating. Currently the average is about 12-15%. I’m putting a link in the source box for you to look at. Hope this explains a little.
PS, another great site is findsolar.com. It’s real helpful.I’ll add it also.

I have a 3.74 kwhdc system which contains 19 panels that are around 2′x4′. The amount of energy they generates varies over the year. As the sun is higher and the days are longer I get more production then in the winter when the sun is low, days are shorter and we have over cast days. I was averaging about 35 kwh per day in the summer and about 10 kwh per day in the winter.
BTW I will break even in less than 7 years on my investment and will save well over $50K over the life of the panels.

Specifically, the amount of energy a solar panel can generate is it’s peak rating (in watts) times the insolation averaged over an entire day (in hours), giving a value in watt-hours. For example:
A 100 watt panel gets an average of 5 hours of good sun/day. It would generate 500 watt-hours, or 0.5 KWH. It might power a desktop computer for a couple hours, or a couple 25 watt CFL’s for 10 hours (with the appropriate batteries).
