CNBM Brand Silicon Poly&Mono Solar Panels

CNBM Brand Silicon Poly&Mono Solar Panels


Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells.


Specifications:


Photovoltaic cells, also known as PV or , are created from semiconductor material such as silicon.

The process of solar conversion works as follows:

1) When light strikes the cells, a specific portion or "band" of the light wave is absorbed by the material.

2) That solar energy causes the semiconductor material to release electrons.

3) The semiconductor material is positioned within an electrical field by using negatively and

positively charged silicon (n-type and p-type), so that all electrons set "fee" from the material are forced to flow-generating electrical current.

Q:Solar Panel Voltage Question?
Hmmm (8v -7v)/ 0 ohms .... shakes head....
Q:Solar panels and your opinion?
Solar power is still an expensive way to purchase power, as of 2007, it was 38 cents per kwh while the cost of power from coal is 0.6 cents per kwh. Of course regulations have prevented new coal power stations from being built so it's really natural gas power stations at 5 cents a kwh that solar has to compete with. Solar is dropping in price but the best you can hope for is for it to reach parity with natural gas someday soon and it hasn't yet. The other issue is that you pay up front for solar power which as any economist will tell you is even more expensive and involves greater risks. However, as part of a strategy to become as self reliant as possible when you retire and have a fixed income, it's a reasonable prospect, not only will the technology become less expensive by then but at that point, fixing the price of the energy costs is more valuable than the cost of the energy. Focusing on personal finance and learning how to invest which very few people know how to do is more important right now. When you retire, hopefully you can afford to build a passive solar home with photovoltaic solar panels and wind turbines but still on the grid for efficient net metering and with a greenhouse where you can grow the staples that you need and perhaps even some biodiesel for your google driven car. Having a reasonable portfolio is really the only way to achieve that goal.
Q:How do you use solar panels?
Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.
Q:Why are solar panels effected by operating temperature?
All PV Solar Panels are affected by heat. The hotter the solar panel, the lower the power output - but how significant is the effect. I decided to test one of our small 6V 250mA Solar Panels to find out. Solar Panel next to halogen lamp with temperature probe. Reproducing the kind of temperatures solar panels experience in hot climates is not easy on a cloudy May day in the UK, so a 50 Watt halogen office lamp was used at a distance of 55mm from the solar panel as a sun substitute. This guaranteed a constant level of light would be incident upon the solar panel ensuring the quality of the results collected.
Q:How tangible do horseshoe solar panels sound?
Sorry to be a prophet of doom again but the fault in the system is that only a small portion of the cell is used at any time of the day, given the high cost of solar panels this is not financially viable. Why not just have a small motor to turn the panel to face the sun, that's been done and it works.
Q:adding more solar panel & battery?
If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
Q:When I make a solar panel what kind...?
Homemade okorder.com
Q:What equation would i need to determine the raise in temperature of water going through a thermal solar panel?
Forget the long winded discussion above. There are so many variables that you cannot calculate the outcome. This does not mean that the experiment is a failure. It gives you information on the fact that water can be heated in this manner, and that you can vary the result by modifying the variables.
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:Solar panel battery help?
I okorder.com and they have deep cycle batteries exclusively made for solar panels. but in theory you should get more than one because it only takes around 4-5 volts to charge the battery and you do not want to have it that high even with a charge controller which i would also recommend getting which is like $50 on OKorder but a charge controller is used so you do not overcharge the batteries and fry them or undercharge the batteries and weaken its life it gets it just perfect. it lets the current go in and when it is charged fully nothing goes in an nothing comes out.... for a inverter the one i was going to get was $70 500 watt inverter but changes it from dc to ac...hope i helped
