Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:Solar Panel experts...please help.?
Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
Q:How many solar panels do you need on your house to power your heater in winter?
You can get over 5 times the efficiency at lower cost by directly absorbing the heat in a solar water-heating collector. Use the electrical panels for making electricity for stuff that needs it.
Q:how can you make your own solar cells for solar panels?
You okorder.com/... Do yourself a favor and invest on good DIY book that include Video, and save a lot of money and frustration. Good Luck!
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
Q:Does anyone know a company that will make custom solar panels?
There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
America should be making the panels and imposing large tariffs on any country trying to import theirs here.
Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?
Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
There is an abundance of free energy available on this planet. Wave, wind, solar, (underground), and many many others that I can't remember right now. If some of the multi-trillions currently being spent being spent by the US government on defence (and the rest of the planet defending ourselves FROM the US) were re-directed towards exploiting sustainable, long-term energy supplies, then much work would be generated and the cost of energy would drop significantly - in the long run. So, why are we not utilizing these sources of energy? Unbelievably short-sighted right-wing political ideology, that's why! One thing almost never reported about nuclear power, is that there isn't much nuclear power fuel available on this planet. I think I can quite honestly state that when the time comes when we are forced to move from non-renewable to renewable energy production, it will probably be far too late with far too much damage done and the environment will collapse and become incapable of supporting oxygen breathing life-forms. I concluded many years ago that capitalism will probably end all life on this planet one day. Capitalism IS right-wing politics! Do you now see where the problem is coming from?
