Product Description of Polycrystalline Solar Panel


CNBM Solar Polycrystalline Series (25W—310W)


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:Are solar panels affordable?
I take it you are in the uk,no grants available that I know of .Affordability is down to how wealthy you are,cost effectiveness? you may!!!recover the cost over about 20 to 30 years depending on your power use,against what you would pay a power Co. Worth while? frankly just another scheme to prise money out of the public,in the name of ecology or cost saving.
Q:How may solar panels/wind turbines may be made affordable?
economies of scale or mass production is the answer to just about any item being made cheaper.be it cars or computers or solar panels. Now, how to get there is the question..... market forces? as more people want a 'greener product demand goes up quantity produced goes up unit price goes down....but that takes awhile.... government help ? subsidies...the US gov takes some of your tax money and makes it available as rebate to people putting panels/wind systems in their homes, and establishes policies to companies to take less taxes if they build wind/solar.... government orders: You MUST put in a solar panel ( or we'll send the Green Police to bust you)
Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
Q:Will my off the shelf deep cycle battery I purchased at autozone work well with solar panels?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:What are your opinions on solar energy?
Solar Panels are a very good choice for our economy today. We can save thousands of dollars a year of electric bills. But they are not practical to buy because these cost thousands of dollars. For the brand new solar panels and installation, it cost more than $20,000 which is not good. They also offer buy now pay later option but it is not good either because it puts you in debt. The solution is, why not do it yourself. There are do-it-yourself guides that shows you step-by-step on how to make solar panels. They are very cheap too. All-in-all, it'll cost you less than $200. But be careful, you might find a DIY solar panel guide are not advisable to someone who don't have experience on them. There is one DIY solar panel guide that I can recommend. It is cheap and it doesnt require you to be a handyman to do it. Check out the site below. If you want to know more about solar panels, check some reviews about it. I included some sites as well.
Q:solar panel efficiency in space?
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:When I make a solar panel what kind...?
Did okorder.com . This might definitely help you!
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
