Company Profile

China National Building Material (CNBM) Group Corporation

China Manufacture 185w-295w Poly Solar Panel with Good Quality

 

CNBM Solar photovoltaic (PV) Panel 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. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

CNBM International Corporation is a professional solar panel manufacturer in China for CNBM brand . Silicon panel ( silicon module), as our main product, has high quality and good service. Our products are very popular in Europe, Australia, England, Middle East, Mexico, Argentina, Chili, Singapore and Africa.

Q:Solar panel placement idea?
It will generate MUCH more current if placed outside of the window. The best position is pointing directly south. Over the period of one day, you will get the most average sunlight pointing in that direction.
Q:How to make a solar panel at home?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:What would be a good battery for this solar panel?
How many batteries you will need depends on what you are planning to do with them which you did not mention? Sunforce makes a 30 amp charge controller part no. 60033
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:Need Large solar panels. ?
Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.
Q:Maintenance of Solar Panel?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
Q:What direction do solar panels usually point?
The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.
Q:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
Q:solar panel roofing?
The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
Q:Composition and function of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
