FAQ:WHAT'S THE ADVANTAGES OF CNBM?
1.CNBM is a state-owned company under jurisdiction of central goverment , one of Fortune 500 .Just because of this ,we can get more support and resources from our government.So ,it is realiable .
2.CNBM's solar products are high-qualified with TUV,UL,VDE,CE,ISO certificates. Our products ranges top in China.
3.Just as I mentioned in attahment ,we signed 500MW project with Urkan under the witness of our chairman Xi Jinping ,CNBM has ability to meet your large quantity needs,Our annual capacity is 1GW.
4.We can offer you a competitive price .Because you are our potential and valued customer .
- Q:I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually quot;connectthe two together. Any help is appreciated.
- Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
- Q:cheapest price for a 20 watt solar panel sold on line
- If okorder /... , cost $75 each. I haven't personally tried that product, but the company has been around for a long time, and is not a fly-by-night. If it has to last, there are dozens of places online that will sell conventional sealed panels. Expect to pay $2.00 a watt on up nowadays.
- Q:
- During a power outage, solar panels do not generate electricity as they rely on the grid for their functioning. This is because most solar panel systems are grid-tied, meaning they are designed to feed excess power back into the grid and draw power from the grid when needed. However, some off-grid solar systems equipped with battery storage can continue to operate during a power outage, providing electricity to the connected devices or storing excess energy for later use.
- Q:Its cloudy out and i have a solar panel that has 3, .5 volt cells But how do i charge it without sun any other ways?
- There okorder Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q:What is the difference between solar panels and light panels?
- The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
- Q:
- Yes, solar panels can be installed on a church or place of worship. In fact, many churches and religious institutions have embraced solar energy as a sustainable and environmentally friendly solution to meet their energy needs. Installing solar panels on a church not only reduces carbon emissions but also sets an example for the community and fosters a sense of environmental responsibility.
- Q:if you move a solar panel or there was a vibration that caused the panel to move, would that affect it?
- No. I've got one on top of my RV and taking it down the road at 70mph doesn't hurt it at all.
- Q:
- Yes, solar panels can be installed on warehouses or industrial facilities. In fact, these large open spaces are often ideal for installing solar panels due to the ample roof space available. Installing solar panels on warehouses or industrial facilities can help generate clean and renewable energy, reduce electricity costs, and contribute to sustainability efforts.
- Q:
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or surrounding areas, an office building can generate enough electricity to meet its energy needs. Additionally, by integrating battery storage systems, excess solar energy can be stored and used during non-sunlight hours, ensuring continuous power supply.
- Q:I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
- if that were true, then anything that absorbs the suns rays do the same thing. Doesn't make any sense to me.
