This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.

CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.

CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.

 

SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

 

WIRING

To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

Q:Questions about solar panels?
I can begin to point you in the right direction. It is a very complicated thing you are asking about. Solar panels produce direct current, in order to store that power for use at night, and on cloudy days, you need a lot of batteries. Those batteries store direct current. In order to use that direct current to power your refrigerator, you need to put it through a thing called an inverter. The inverter produces AC from DC. You may have seen one for sale to plug into the lighter in a car so you can use things that require AC in your car. The inverter looses power doing the conversion. Over time, you can purchase direct current appliances, and make the system more efficient. Years ago, a decision was made to go with AC because of transmission issues (you can move AC across a wire a long distance, and DC is more difficult to move). Many appliances convert AC to DC internally to do their work, but such appliances are expensive. Have I answered your question? Not really. You should understand your question better though.
Q:How to build solar panels?
you okorder.com they have solar panels
Q:What factors effect the amount of electricity produced from solar panels?
irradiance in watts/meter^2 (000-800w/m^2 depending on air quality) COS of angle to the suns rays efficiency of the panels (usually about 5%) age of the panels(one dead cell can drop an entire panel from the array) how dirty are the panels (dust, bird poop, leaves, shading) efficiency of the inverter (usually about 90%) All of these factors affect the amount of electricity produced. One other consideration is that in areas of extreme hot and cold the band gap of the silicon is changed.
Q:Tips for convincing my school to put solar panels on the schools roof?
Unfortunately installing Photoelectric Solar panels on your school would probably cost more than the entire school budget. In order to make this sort of proposal you would need to have some hard numbers to show exact dollar amounts of costs and benefits. You would need multiple quotes from companies that install solar panels and information from the electrical company that would have to tie the system into their grid. This is a HUGE undertaking. If you really want to reduce carbon emissions, suggest ways to reduce the energy use within the school instead of converting to solar. Better windows, doors, and roof insulation. If you have a leaky roof, fixing that would get rid of water damage and better insulate the school thus saving energy. Suggest plans to reduce electrical usage like having computers go into Hibernate mode after 0 minutes, turning off lights in rooms that aren't getting used, etc... Many people are fooled into thinking that solar power is this awesome free energy source. IT is NOT. Solar panels are great for powering small items or for getting power when you have no other way of getting connected. However it takes MORE electricity to create a solar panel than the solar panel will ever produce in it's ENTIRE lifetime. Do some research into the production of silicon crystal and semiconductors and find out how solar panels are made. Until the technology improves greatly, solar is not a green power source other than generating money.
Q:What home appliance can be powered by a solar panel?
First and foremost, you are talking about photovoltaic panels. These harness solar energy and convert it to electricity. The downside to these is that they are expensive, although you will see a huge return on your electric bill in usually 5-7 years. The photovoltaic panels produce DC electricity, so if you want to power your home appliances you will need an inverter that takes DC electricity and converts it to AC (since almost all home appliances run off of AC). You will also need a battery and an optional but very useful charge controller. The battery stores electricity that is generated from the sun to be used on cloudy days. The charge controller is the brains of the operation and deciphers how much electricity should go to the appliance(s) or the battery.
Q:Selling homemade solar panels?
Aren't there any safety or efficiency standards you have to comply with? If I were buying solar panels I'd want to be sure the manufacturer was competent and licensed as a manufacturer/retailer. If someone brought a case against you for something that went wrong, and the brand name components were named as part of the problem, then yes, those brand name companies would certainly think there was a legal complication. Just do your research first. Your local chamber of commerce or university legal department would be able to help you.
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
Or maybe he should increase tax benefits for domestic manufacturers of solar panels, so that they are actually manufactured here instead of in China? Oh, wait. He is. But I've seen questions in which you whine about tax cuts for renewable energy because you think renewable energy can't be profitable.
Q:Homemade Solar Panels?
Hey David, yes, we have built plenty of them. If you are into the do it yourself world, the easiest type to build is the Batch Preheater type. What you need is an old water heater, something small, like an under counter model, 0 to 30 gallons in size. It has to be one that hasn't rusted out yet and started leaking. We stopped at a local plumbing place in town, they are always throwing out units they have removed from homes because the new owner wants a larger unit, or gas versus electric, and so on. He sold us a pretty recent model for $0. Take the water heater home, and strip off the outer metal housing and all the insualtion so all you have left is the tank. Clean it up, and paint it with black paint. Now build a wood enclosure, something the size of a dog house that your tank will fit inside of. Use a glass panel for one side of the roof. What works best is an old window pane someone is throwing out that is about the right size, then build your dog house to fit it. When it's done, put some styrofoam insulation panels around the back and side walls to keep the heat in when the sun shines on it, then mount your tank inside. Put your dog house someplace in the sun, run the cold water that normally feeds into your water heater into the tank (in the cold inlet side), then run a pipe from the outlet of the tank to your regular water heater. We have one just like this installed in the northern midwest, it works great about 7 months of the year. Usually in the summer if it's about 75 degrees outside, the water comes into the house at around 00 degrees, then the regular water heater only needs to add another 25 degrees to the water to finish it off. Since the water starts out at about 56 degrees, the solar preheater ends up doing about 65% of the work. In the winter, we simply drain the tank and lines to and from it, and route the cold water directly to the regular water heater. There are some designs on line, try googling, Batch Water Preheater. Take care, Rudydoo
Q:Who created the first solar panel?
The first photovoltaic cell was developed at Bell Labs in 954. The team included G.L. Pearson, C.S. Fuller, and D.M. Chapin. A panel is composed of many cells. They respond to a wide range of wavelengths, not just UV.
Q:How can I regulate current from a solar panel?
If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
