Product Description
Solar Polycrystalline Series Panels
Introduction of Polycrystalline Solar 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. Polycrystalline 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.
Characteristics of Polycrystalline Solar Panels
I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.
V Junction box: Multi function junction box with water proof.
VI Long lifetime: ≥25 years; Less power decrease
VII Good performance of preventing from atrocious weather such as wind and hails.
VIII Resisting moisture and etching effectively, not effected by geology.

- Q:my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP
- If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
- Q:i hav e a project for school we need to calculate cost to buy and install solar panels in our school
- to okorder / you should really be able make report with this informatin. So for your school it would cost millions, you need to figure out how many kilowatts your school use, then use the information above to calculate how large of system would be required you will be very impressive and the most informed person in your school.
- Q:I was thinking of having some installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 2 months out of the year and in the summer roughly 4 hours of straight sun.

- Q:How much space do solar panels require?
- The space required for solar panels depends on several factors such as the power output of the panels and the efficiency of the solar cells. On average, a typical solar panel requires around 10-20 square feet of space. However, it is important to note that solar panels can be mounted on rooftops, installed in large solar farms, or even integrated into building materials, allowing for flexibility in their placement and utilization of available space.
- Q:How much would solar panels cost for: A Cell phoneA average houseA car
- They would cost quite a bit but the user would likely be eligible for some energy credits from the power company and their cell phone carrier which would bring down the costs
- Q:I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!
- Solar okorder in their survival discussion in the archive, this exact project was discussed at length.
- Q:What materials are solar panels made of?
- Solar panels are typically made of photovoltaic (PV) cells, which are primarily composed of silicon, along with other materials such as metal frames, glass, and encapsulation materials.
- Q:So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?
- The solar panel doesn't output enough power to run the fan directly, your best bet would be to just hook the fan back up to the battery, and then rig the solar panels up to help charge the battery and remove some of the load from the alternator. If you're trying to reduce your emissions/increase fuel economy then you'd be better of setting up a switch to disconnect your alternator when its not necessary to have it on. The alternator runs off a belt from the engine which requires some of the power output from the engine. Having this connected all the time increases the amount of gas used (marginally) but you'd be saving more gas doing that and using the solar panels to keep the battery topped up.
- Q:Are solar panels suitable for all climates?
- Solar panels can be suitable for a wide range of climates, but their efficiency may vary depending on factors such as sunlight intensity, temperature, and cloud cover. While solar panels can still generate electricity in cloudy or cold climates, they tend to perform best in regions with abundant sunlight. Advances in technology have made solar panels more adaptable and efficient in various conditions, making them a viable option for many different climates.
- Q:Can solar panels be installed on ground-mounted structures?
- Yes, solar panels can be installed on ground-mounted structures. In fact, ground-mounted solar panel systems are a popular choice for residential, commercial, and utility-scale projects. They offer flexibility in terms of location, orientation, and scalability, making them an ideal option for areas with limited roof space or shading issues. Ground-mounted structures can be customized to optimize solar panel angles for maximum energy production and are easier to install and maintain compared to rooftop systems.
