Solar Polycrystalline Series Panels

Introduction of Solar Polycrystalline Series Panels

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.

Q:Need Solar Panel Guru.....?
I'm inferring that your goal is to save money. You're on the right track with your energy star appliances - saving energy is far better than installing solar panels to cover energy that will be wasted. You may have an opportunity with solar hot water - you would need a large storage tank with 3 people, but that would be the best use of your roof in my opinion. Check with a professional installer, it may make financial sense. Although you could make your own heating panels, it's hard to make a solution as durable as commercial panels. And if freezing is an issue in your area, you would have to drain a homemade system in the winter. With an evacuated tube commercial system, you could keep running right through the winter. In the summer, instead of running those expensive air conditioners, could you just have a cool room in the basement? Anyone who wanted privacy could still go to their regular room and run fans. We have no A/C in our house, and manage, even on those 00+ days. Sounds like awnings or other window coverings might be a big help for you, at least until you can get some deciduous trees in to shade the house in summer. I would advise against making your own solar electric panels. They would not save money over the long term. And check panel prices - they have dropped 50% this year, according to a recent Newsweek article.
Q:Does a solar panel work on a cloudy day or a rainy day?
depending whether the solar array is back to grid or stand alone. Back to grid refers to the array being connect through the inverter to the main electricity supply grid. So when you are producing electricity from the solar array it feeds back into the main grid. Now if you are using more electricity than your array is producing then none will feed into the grid. The stand alone systems require batteries, which are charged from the electricity produced by the solar array. Solar arrays produce electricity on cloudy and rainy days but at a greatly reduced rate ; therefore little to no usable electricity is produced. Stand alone systems require batteries to store the electricity for use at night time and other times when the array is not producing . The back to grid systems require little to no maintenance as the electricity produced is fed back into the electricity network and stored there. Your meter is replaced with a dual meter . It reads your usage and your production. If in Australia you will get paid for the electricity you feed back into the grid. hope this helps.

Q:How do you hook up solar panels to your electricity?
nowing what to do with unused renewable electricity is always a dilemma – hooking up to the grid has to be the preferred option. If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid. You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power. The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power. The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid. Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid. If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.
Q:What is the real cost of Solar Panels?
What's your Source (Optional)
Q:How to maintain a battery with a solar panel?
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
Q:highest known watt output for solar panels?
Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.
Q:question about solar panels....?
Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
Q:does vibration affect solar panels?
No. I've got one on top of my RV and taking it down the road at 70mph doesn't hurt it at all.
Q:If I shine different color lights (bulbs) on a solar panel, will it affect the electricity output?
