Specification of  Solar Polycrystalline(270W-290W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

Q:Solar Panel Help, Trying to go green.?
Ideally, you should not be trying to run individual appliances off of a solar panel. What you should be doing is selling the power harvested from these panels back to the power company as a savings from your power bill. Here in southern California I have heard of people actually receiving monthly checks from the power companies.
Q:What size and watt solar panel?
I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
Q:where could i buy a cheap and low cost solar panel regulator?
Solar cells shouldn't need a voltage regulator for simple projects like driving motors or powering CMOS electronic circuits. I would need to know a little more on your goals for the project to help. However, I will put a few links that may be helpful to solar cells and some voltage regulators. The first link is general solar cell info and includes manufacturer lists at the end. The second is a link to educational solar cell kits and cells that may be useful for you. The last one is Digi-Key which is good for finding components to make your own voltage regulator. Hope this helps with your project!!
Q:how many solar panels needed for Heater and AC?
Please excuse my bluntness, but you are not ready to ask these questions. This is a very complex issue. The how many question depends on what you expect of the system. Are you attempting to be off the grid? If so the system will have to supply all of your electrical needs, including those at night. You would need batteries. If you will be on the grid and want to supply all your electrical needs, your system will have to average the total daily usage. This will vary from one season to the next, so you will need to find out your annual usage. If you just want to reduce your electric bill, you need to pick the acceptable installation cost, and work with it to determine what it will buy In your shoes I would do some studying. Check out solar panels in the green search box above, and on the Internet. This will help you ask questions that are easier for us to answer.
Q:Tips for convincing my school to put solar panels on the schools roof?
When okorder.com/ Good luck but the best way to win is to find a way to get it done and then they can't say no.
Q:Computation of Solar panel requirement?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q:help setting up a solar panel system?
If okorder.com/ If the minifridge is one that plugs into 2 volts, that should be okay. Anywhere you can eliminate the inverter will help. Such as converting the stereo over to 2 volts. The nominally rated panels should be mounted at an angle to maximize the solar aspect/exposure. Essentially your lattitude plus 2 degrees for simplicity. If you add 60 Watts in panels you will do much better. Your 3 panels when installed correctly will actually yield over 5 Watts each panel at midday. If you do not achieve that, something is wrong in either the wiring, or a panel. It translates to about point2 Amperes to point5 Amperes at midday. If wired in series for 36 volts, the total current output will be same as a single panel (nominal 5 Watt), but at a higher voltage. If wired in parallel, you achieve the 45 Watts at nominal 2 volts. Watts is voltts times Amps. Also converting your tools over to run off the 2 volts will help, Or charging your tool batteries off the 2 volt buss. There are buck/boost circuits that would be capable of charging the common 4.4 and 8. volt tools out there.
Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:Do homemade solar panels really work?
Yes there are plans and testimonials all over the internet and dozens of vids on youtube for homemade panels
