Solar Polycrystalline Series

 

 

Introduction of Solar Polycrystalline Series

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.

 

Characteristics of Solar Polycrystalline Series

I.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

 

III.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IVAI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V.Junction box: Multi function junction box with water proof.

VI.Long lifetime: ≥25 years; Less power decrease.

Q:why wont my solar panel make my dc motor work?
Ok okorder.com
Q:How many solar panels would I need to power my washer machine?
Solar panels produce power in proportion to the amount of sun light and inverse proportion to the temperature. To use solar power you will need in addition to the panels a bank of batteries a charge controller and an inverter to convert to 20v. The panel(s) will only be used to recharge the batteries and the batteries connected to the inverter is what is going to run your washing machine. You therefore need to know how long is the machine going to run, how often and how much charging can you expect to get from each panel in order to figure out how many panels you will need and how many batteries. If you do only one load very infrequenly, you will be able to use a smaller battery bank and charge at a lower rate.
Q:Price and energy production of solar panels?
A small panel will not produce much power. When people put solar electric panels on their house with the goal of saving money, they generally put up a lot of large panels - 200 or 500 square feet worth. Its hard to save money with just one panel. The only way to get close on how much it will cost and whether that represents a savings is to get out your electric bills for the past year, and call a local solar installer for a quote. The system on our house cost $20,000 and we got back $8,000 in incentives, so $2,000 net. It can save money, but that will be over many, many years.
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:How can I run my house purely off of solar panels?
I ve been researching this myself! I need appr 6000w per year. I live in MN which a zone 5 on a solar map (4.4 hrs of sunlight per day). I would need 56 panels at 300w each!!! pffft - I d be dead before I recouped my cost, plus my roof isn t even that big! Sure, I can reduce my bill, but then again the $ to reduce it..... I m now looking into wind turbine since it always seems windy here.
Q:What Size Solar Panel Would I Need?
It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.
Q:What do I need to install a 40 watt solar panel?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:what do we mean by efficiency of a solar panel?
That portion of the sun's light to which it responds, of which it converts 20% to electricity.
Q:How will i construct solar panel?
For powering a something that works on DC, like a gate opener, Elaine is right, and in some cases only ONE bigger cell is sufficient due to battery storage; however if the appliance is 20v AC, then an inverter is needed also. MOST of Elaine's answer is good, but a few corrections are needed: Plywood - use EXTERIOR grade only, and even then it can warp; chipboard or waferboard is preferable as it does NOT warp, BUT is not available most places in 3/8, /2 nominal, (5/32) is usually the thinnest available, and it is heavier than plywood. DO NOT use particle board. Superglue - NO, it dries too fast to be useful, in most cases. Wires - For a single cell OK, but for larger panels the best wire is tabbing wire, (which is flat,) which is available from all commercial solar cell dealers. Be very careful soldering this to the cells, as unless you buy the expensive flexible cells, they are easily damaged; I suggest also getting flux pens with liquid flux. Diode - Necessary, but needs to be large enough to handle voltage and current. Usually 25v and 5-30 amps,, one per panel. Plexiglas - OK, but NOT as long lasting as glass; best glass is the special solar glass which is designed to pass almost all of the proper light frequencies, but IS expensive, and usually needs to be specially ordered since most glass stores do not stock it. Double panes work well with the outer pane glass and the inner plexiglas, (to protect the cell if glass broken,) IF where might get damage, such as 'ground' mounting. AND Frame kits are available for larger panels, but IF you make your own, a good table router is a great advantage. Inverter - IF used for 20v AC appliances you MUST have an inverter capable of handling the load, and the best ones are modified sine, or true sine, wave types, and even the best are less than 50% efficient. Note that they will last longer if NOT used at more than 2/3 capacity.
Q:Do solar panels plug into an outlet?
No they don't have an outlet. The wires attached to the solar panel can be attached to say a battery and keep it charged during day even during.use. At night you use battery power.
