FAQ

We have organized several common questions for our clients，may help you sincerely：

①What price for each watt?

It depends on the quantity, delivery date and payment terms,

②What is your size for each module? Can you tell me the Parameter of your module?

We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.

③Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also the off grid solar system, we can also provide you service with on grid plant.

④What is your warranty system?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

• Quality Products certified (TÜV, UL, CE, ISO)

Q:How do solar panels affect satellite dish reception?: Solar panels can potentially obstruct the satellite dish's line of sight to the satellite, leading to signal interference and reduced reception quality.

Q:Im doing this project on Solar panels and im not so sure what they are!some questions i have are who invented them and what were they invented? If u could know anything on Solar Panels i would love to hear it. Thanks!!!!!!!!!!!!!!!!!!!!!: Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.

Q:I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.: if they get energy from burning coal, they will be destroying our atmosphere. if they use solar panels, they can use natural energy from the sun without harming the environment.

Q:Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!: Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.

Q:what size would the panel be/ I live in the caribbean so plenty of sun!: a minimum of 4000 watts, 5KW may well be extra desirable and you do choose an inverter and batteries and in all hazard a variable frequency force till the pump motor is rated for DC which I doubt. suited answer is touch a close-by electrician to do the artwork.

Q:Can solar panels be used for charging outdoor power tools?: Yes, solar panels can be used for charging outdoor power tools. Solar panels generate electricity by converting sunlight into energy, which can be used to charge batteries or power devices like outdoor power tools. This eco-friendly and cost-effective solution provides a sustainable way to charge outdoor power tools without relying on traditional electrical outlets.

Q:Can solar panels be installed on a warehouse or industrial facility?: Yes, solar panels can be installed on a warehouse or industrial facility. In fact, these large rooftops often provide ideal conditions for solar panel installations, as they have ample space to accommodate a significant number of panels. Installing solar panels on warehouses or industrial facilities can help offset energy costs, reduce carbon emissions, and contribute to the organization's sustainability goals.

Q:Why would someone use a solar panel? Does it have to do with the economy right now, global warming, or what?: All of the above plus freedom and being part of the solution instead of the problem. Energy is doing nothing but costing more. Once you buy a solar panel your price is frozen for the life of the solar cell. They last at least 30 years maybe up to 50

Q:Can solar panels be installed in areas with high humidity?: Yes, solar panels can be installed in areas with high humidity. While humidity can slightly affect the efficiency of solar panels, it does not prevent their installation or operation. Modern solar panel technology is designed to withstand various environmental conditions, including high humidity, and they can still generate electricity even in humid environments.

Q:I am planning to buy some solar panels for my cabin and i want to be able to store the electricity. what kind of batteries should i get? i will be running simple things like a tv and radio. where can i buy these batteries? where should i look for the best batteries?: If you will be storing them outdoors, you can use auto batteries. Indoors, use sealed marine batteries. Number and size depends on your needs. You will need a charge controller between the solar panels and the batteries to get the maximum power out of the array and to avoid damage to the batteries. And you will need an inverter to convert the 2 or 24 volts to 20 or 240 VAC. One large lead acid battery will supply about 000 watt-hours of energy, enough for 200 watts for 5 hours. You have to look at your loads and decide on how many batteries you need. Frequently it is cheaper to buy new appliances that use less power, as that power difference can save a lot of money in batteries, inverter, charge controller and solar panels. But it sounds like a few thousand watt-hours will be enough, or 2 large batteries. The real limiting factor is how much money you want to spend for the solar panels themselves. .
