Introduction of  Poly solar panels CNBM

Polycrystalline  Solar Panels 305W 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.

 Polycrystalline  Solar Panels 305W With High Efficiency

Feature

1.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

3.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

4.Long lifetime: ≥25 years; Less power decrease.

5.Resisting moisture and etching effectively, not effected by geology.

6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:Are solar panels worth the investment?
Yes, solar panels are worth the investment. They offer long-term financial savings by reducing electricity bills and the potential for selling excess energy back to the grid. Additionally, they contribute to a cleaner and more sustainable future by reducing carbon emissions and dependency on fossil fuels.
Q:I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
It would just be cheaper to run the power lines back to the house but what ever you do DONT take electricity from the drop above the meter for free at night. That would be wrong! Lol sticking it to the man!
Q:And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
In regards to my research about these two types of Solar Panels, I suggest that the Monocrystalline Solar Panel would be great! It is affordable and also more convenient to install. Using a 400W Panel means fewer panels and less installation time, in addition to fewer connections and transmission losses which results in big savings and a faster return on your investment.The Topsun Solar Panels boasts efficiency of up to 6.77% and use cutting edge technology for the best heat dissipation in the industry.
Q:Me and my friend have made our own functional solar panels for considerably less than retail prices and we are thinking about selling them. Are there any legal issues regarding this? Would I need any special licenses or anything? Would using brand name components or parts in the panels make any difference legally? I want to know before I just go out and start doing it. Thanks!
They are your property. If you want to sell them, have at it. Of course, as soon as the government sees you making some money, they will descend on you like hyenas for ;their 'share'. If you apply and get a 'commercial' permit, they will be in you pocket in a flash. The government will steal anything they can get their hands on. They use 'zoning laws' to carry out their ruse. Then they call themselves your 'partner'. Same as the mafia does. They have a lot of worthless bureaucrats that want somebody else's money. In California, most of the government workers seem to be communists. They hate business and are extremely jealous of any entrepreneur. They think they are experts on Fair business Practices. Most of them have never worked an honest days work in their life. Let alone think up an idea such as yours.
Q:I have had this 2v portable Solar Panel for my apartment for awhile. Only problem is that I have no balcony and I can barely get enough sun to use it with my Cobra 450 400-800 watt outlet converter. Can someone advise me a better method to use these? Like do I have to get more 2v solar panels? I have a small apartment and use it on one window. Also is it possible for me to buy a portable storage tank to store the energy gathered from the sun by the solar panel?

Q:Can solar panels be installed on a barn or shed?
Yes, solar panels can be installed on a barn or shed. In fact, barns and sheds often have large roof spaces that are ideal for solar panel installation. This allows the building to generate its own clean and renewable energy, reducing electricity costs and environmental impact.
Q:All I ever heard is how easy it is to get solar panels for a persons home. I live in Arkansas and to do my house it would cost 25000 that I dont have and No state incentives. So where do I go and get these free solar panels? Thanks for the help

Q:i don't know very much about it, but can you somehow take off the little solar panels off of the outdoor light things and make it so you can hook an outlet up to it and plug in to it like a phone charger for electricity.
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:Are solar panels fire hazards?
Solar panels themselves are not fire hazards. However, if there is a faulty installation, damage, or improper maintenance, there is a slight risk of fire. Regular inspections and adherence to safety guidelines greatly minimize this risk, making solar panels generally safe and reliable.
Q:i am wanting to build a small tiny house running 3-4 2 volt 5 watt light bulbs for a lighting source and using a Koolatron Fun Kool 26 Quart 2V Portable Mini Fridge This cooler consumes 4.5 amps at 2 volts. The conversion is: 4.5 amps (X) times 2 volts (=) equals 54 watts. and i want a solar system that will have back up for 2 days with the lights on for probly 5-6 hours a day so theirs no room for error
you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
