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:solar panels and wind power help?
Hi okorder.com
Q:Do you need to pay for electricity if you have solar panels?
Okay--here it is (without the techie buzzwords!) Solar power has a start up cost--the panels and related equipment. But the amount it cost to operate is virtually zero--pretty much jsut servicing th equipment o keep it working properly--much as you do any other appliance. How much electricity you will still have to buy depends on four things: a) how much your system can produce. If you have a 4000 watt system, you'll still buy a fair amount of power. Abigger one--and you will need less from the power company b) how efficient you (your home and appliances are). The more efficient, the less electricity you use. Obviously, things lie CFL bulbs are very helpful here c) Are you willing to invest in a battery storage system to store electricity from the system for use at night? Right now, that's still pricey. But these are starting to come on th emarket more. If you aren't ready to do tha tnow, you can always add it in later. d) can you sell excess power back to the power company.? In California, the law requires utilities to do this--but its not a universal yet, so it depends on where you are. How this works: you are still hooked up to the power company. Any time you need more power than the solar system produces, yur system jst draws it off the power grid--jsut as always. But--any time you are using LESS than the amount of power your system is producing, the excess automatically feeeds back into the electric grid and a special peter credits you with the power. There are cases wwhere people have goene on a long vacation in California and when they got home, the power company owed them several hundred dollars! You'll need to do some research, price thngs, take your own lifestyle into account, and decide what the best choices for you are. It sounds complicated--and to an extent it is. But the reason is tha tyou have a lot of choices tha tyou can make work to your advantage, instead of jsut writing a fat check to the power company every month!
Q:what is the cost of getting km sq of solar panels?
As okorder.com/ They are working on a reactor that makes diesel and electricity concurrently out of coal, biomass or possibly garbage in a non-polluting process.
Q:What exactly is a solar panel?
What a solar panel REALLY is is a political rip-off in which the government takes money from me to help you buy solar panels that produce a fraction of the power you could have bought with the money they stole and which required more volatile chemicals to manufacture than would have been created in the consumption of that same power.
Q:Solar Panel?
Though wind energy is the big thing at present, and I derive a significant part of my income from doing engineering on these wind farms, I personally prefer a wood-fired boiler steam turbine generator combination as the best renewable energy system. Wind generation works great when the wind blows, but if you intend to go off-grid expect to invest in energy storage and some other form of backup power. Solar photovoltaic panels are about 6% efficient at best, and that's only when the sun is shining brightly. If you consider that trees (biomass) are a completely natural, renewable energy resource, and couple this energy resource with modern clean combustion technology, this makes for a great dispatchable, long-term sustainable, ready-when-you-need-it solution. Go wood!
Q:Making a Charger out of small solar panels?
The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.
Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:A question about Solar Panels?
Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
Q:how much money do solar panels cost?
There are a lot of factors to consider. Net metering, utility rates, number of hours of daylight, size and orientation of roof or other location. I can tell you I had a 3.74 kwhdc system which reduces my bill by about $200 a month. It cost $26K installed, I received a $0K rebate from my utility and a $2K federal tax credit. Businesses have always been able to get a 30% fed. tax credit, this year everyone gets it. If this is a business you plan on owning for a long time there is no reason why you can't do the install in stages. Of course making sure you are conserving as much energy as possible will also help. Using energy efficient lighting, appliances and electronics, Turning off lights, monitors, computers, printers etc when people go home, sharing printers and other resources, adjusting the thermostat and using natural light can all help reduce your electricity usage.
