Introduction of  Poly solar panels CNBM

Polycrystalline  Solar Panels 230W With High Efficiency

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:Selling homemade solar panels?
you might first patent the design . Make sure everything is well documented . talk to patent agents and lawyers . Then instead of becoming a seller , introduce your design to established companies. They already have all the licences , lawyers, codes..etc to sell , install, advertise to buyers . they can often make you a partner or buy your design for a lump sum . Solar is a huge step . Best wishes
Q:Hi trying to learn more about Solar panels!?
Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
Q:what is the best solar panels to use on my new house(tube or flat)?
The type solar system to be installed your new house depends the shape and dimensions of house.Himin newly launched solar house.
Q:what are some methods for capturing low voltage electricity from solar panels?
On a day that's really dark, I don't think there is anything that can reasonably be done. The voltage is low because the power coming out of the panels is low. A circuit could step that voltage up, but could not increase the power. According to our user's manual, it takes 30 to 40 watts to run our inverter. So if the panels are putting out more than that, it's worth running the inverter. If not, then it's better to not even run it, so the inverter cuts out. A charge controller for a battery would have similar behavior if well-designed. Our array is large enough that during even relatively dark days, there is enough power so that the inverter won't cut out.
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:anybody owns a house solar panel system does it really save you money on electricity?

Q:I would like to know mire about solar energy ?
You do'nt want to build a solar panel. The heart of a solar system is the Converter. From that you know that you will have 20 VAC output, but you need to know what kind of input you need prior to building your system. That way you can buy solar panels at that voltage or hook them up in series to get the voltage you need to be converted. You'll then need to calculate the power (watts) you use from day to day, that way your solar system can provide you with what you need. Problem is, NOW, you have a choice to make. If you want to just cut down on your reliance of grid power, there are companies that will do all this for you, and hook you up to the grid so that by day you will be using nothing but solar power, but at night you will be running off the grid. These companies generally make it harder on you to buy the system outright by not providing you maintenance or repair services.....so that could be an issue, which is how they keep you 'leasing' the equipment from them. OR You can go completely off the grid in which case you will have to buy back up batteries and wire them in so that they are charging during the day so that you will be running off of battery power by night.
Q:How to tie small solar panel system into my house's electircal system?
How to tie small solar panel system into my house's electircal system? It's very complicated. Just for starters, if you plugged your solar panel into your electrical outlet, you would probably see smoke and fire, not electricity. Of course anything CAN be done. But this one is truly unfeasible at the consumer level. The only way to send power back into a live system is to synchronize the phase voltages. In your case you would require the solar panels, a battery backup system, a voltage inverter and some type of industrial synchronizer (probably a generator) so you could sync your inverter output to the utilities output. Solar is still more of a standby or supplemental type power at this time. The easiest way is to supplement your hot water by using solar panels to heat water rather than create electricity. If money was not much of an option then you could theoretically run your whole house without the need for any synchronization but have a gasoline or diesel generator to keep your battery pack topped up when needed.
Q:What specification of solar panel do I need?
You will need, A battery to store the electricity from the solar panel. The amount of electricity from the panel varies up and down as things such as clouds, position of the sun, etc. reduce the amount of solar rays hitting the panel. The battery stores it all, the ups and downs, and sends it back out at a steady voltage so you can operate your p.c. / appliance. A minimum of 45 watts solar panel. 60 watts would be preferable. 45 watts will charge a battery in one day under ideal conditions. You turn the panel as the sun moves across the sky, no clouds. 60 watts will charge a battery in one day with out moving and regardless of clouds. A controler to prevent the electricity from flowing backwards from the battery to the solar panel when the sun goes behind a cloud or sets at night and the charge drops below the voltage of the battery. A good controller will tell you the charge condition of your battery so you know when it is too low to operate your p.c. safely. And finally an inverter with True Sine Wave capability to change the electricity from the battery into usuable power for your PC and other electronics. Not all inverters produce true sine wave electricity. The electricity has static in it and will make your pc screen jump around and not function as it should. New digital T.V.'s also require true sine wave electricity to operate. Go the extra cost and get the inverter with true sine wave and be happy with the way your p.c. functions. Figure out how many Watts your p.c. or appliance will draw. and match the Inverter to the need. Do not go too big, as they cost more and consume more of your stored electricity to operate. Save as much electricity as you can. You will be able to operate your p.c. appliance longer. When not using your p.c., you can operate your T.V. or other low watt appliance.
Q:How much do solar panels cost?
I have a coworker that did her home with a 5 kw system with batteries and whole house inverter. It cost $55k before the Florida $20k rebate. She sells back to the grid, but the system will not pay for itself for at least 20 years. It will not run the air conditioning, either. The batteries will give 3 days power for everything else without sun. There are companies trying to lease solar equipment, but none seem ready for prime time, yet. I've been to Sun-Electric (Venetian Causeway across from the Herald building) in Miami to buy surplus panels. They have a whole roof of panels and sell back to the grid, but they also have a room with batteries and an inverter and close shop at night.
