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: If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?: Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!

Q: Can solar panels be used during a power outage?: No, solar panels cannot be used during a power outage unless they are connected to a battery storage system.

Q: Can solar panels be installed on schools or universities?: Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. By installing solar panels, schools and universities can reduce their carbon footprint, save money on energy bills, and provide a valuable educational opportunity for students to learn about renewable energy.

Q: If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.: Solar panels do not wear out the way machinery does. The semiconductors used give up electrons by receiving photons, and do not experience a net deficit of particles. However, if you placed a heat source such as a heat lamp too close to a solar panel, you could damage the panel by overheating it, which would denature the semiconductors or cause damage by scorching or melting. The problem would be the heat, not the light. Solar panels do have a finite life expectancy, though it is several decades under normal circumstances. The panels will eventually become scratched, warped, and dented. The electrical conductors will eventually be broken by metal fatigue as the panels heat and cool on a daily basis. So they will die of old age, but they don't wear out in an electrochemical sense.

Q: is a wind turbine better than solar panels: is your place has enough wind or sunshine ? the turbine is not easily for maintenance. the solar panel is more stable, one broken panel willl not affect the whole system much

Q: Can solar panels be installed on a parking lot or carport?: Yes, solar panels can be installed on a parking lot or carport. In fact, this is a growing trend known as solar carports or solar parking lot canopies. These structures not only provide shade for vehicles but also generate clean and renewable energy. They are a great way to utilize unused space for solar power generation while providing additional benefits such as reducing heat island effect and offering covered parking.

Q: Can solar panels be installed in rural areas?: Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal for solar panel installations due to the availability of open spaces and ample sunlight. Installing solar panels in rural areas can provide clean and renewable energy to these communities, reducing their dependence on traditional energy sources and improving energy access.

Q: I am doing a science fair project on solar panels, and I need four solar panels to conduct the experiment. I would only need the solar panels for a week. What type of solar panel should I get?: Your USB power booster may be fragile and is likely expensive, so possibly you should get your 5 volts some other way. 3.7 volts plus a .2 volts D cell is 4.9 volts which is likely close enough for charging most anything with a USB charging cable. If bright sunlight is falling on your solar panel the battery voltage will go to about 5. volts charging at 700 MA, which is also likely acceptable, and will generally be less as part of the 700 ma is being used to charge something else. Also 300 ma may be more typical output of your solar panel even when the sun looks like it is bright. Over charging is unlikely unless the lithium cell has a lower amp-hour = AH rating than the Ni-cad (or nickel metal hydride NiMH 4 AH) D cell, but perhaps you should disconnect the solar panel, if it has been more than one bright sunny day since you charged something with a USB cable. If your battery reads over 5 volts with the solar panel unlighted or disconnected, you are likely to over charge either the lithium cell or the D cell. The PCB protected may complicate adding the D cell (probably not) so you may want to follow your original plan. Your solar panel may send as much as 9 volts to your PCB protection board, when the lithium cell does not need charging: Can the protection board tolerate 9 volts? Probably. If in doubt you can put either a .5 volt or .2 volt rechargeable D cell in series with the solar panel which reduces the input to your PCB protection by about .5 volts. That D cell will over charge, unless you replace it weekly, perhaps oftener. I think your PCB protection prevents over charging and cuts off the load if the lithium cell is discharged to an unsafe level or the load is demanding excessive current. Only the last is a possible problem = one of your USB cords may demand an amount of current that the PCB protection considers excessive. Your USB booster needs about twice as much current as the usb cord is supplying. You don't get the extra voltage by magic. Neil

Q: Can solar panels be installed on remote monitoring systems?: Yes, solar panels can be installed on remote monitoring systems. Solar panels provide a reliable and sustainable source of energy for remote monitoring systems, allowing them to operate autonomously and continuously in remote locations without the need for grid power or frequent battery replacements.

Q: Can solar panels be installed in areas with high levels of saltwater exposure?: Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed to withstand such conditions. These panels are typically made with corrosion-resistant materials and undergo rigorous testing to ensure durability in marine environments. Regular maintenance and cleaning may also be required to prevent salt buildup and optimize performance.
