5.FAQ of Solar Module

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 Solar Cells, 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

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

⑤How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.: If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.

Q: Can solar panels be used to power a university?: Yes, solar panels can be used to power a university. Solar energy is a renewable and clean source of power, making it an ideal solution for large institutions like universities. By installing solar panels on rooftops, parking lots, or open spaces, universities can generate a significant amount of electricity to meet their energy needs. Additionally, universities often have large campuses with ample space for solar panel installations, making it feasible to generate a substantial amount of solar power.

Q: I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.: The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.

Q: Can any body tell me how much Electricity can 0 Standard solar panels produce in a day( in terms of Watts)Or else please tell me how many Watts is 5 volts of electricity?: You have to know the amperage to figure out the watts. Volts x Amps= watts

Q: What is the warranty on solar panels?: The warranty on solar panels can vary depending on the manufacturer and the specific product, but it typically ranges from 10 to 25 years.

Q: Can solar panels be used in areas with high levels of UV radiation?: Yes, solar panels can be used in areas with high levels of UV radiation. In fact, solar panels are designed to withstand UV radiation as they are made with materials that can handle prolonged exposure to sunlight. However, it is important to note that high levels of UV radiation may slightly degrade the efficiency of solar panels over time. Nonetheless, solar panels are still an effective and sustainable energy solution in areas with high UV radiation.

Q: Why should I have a Generator if I have Solar Panels.....?: Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.

Q: I don't want to spend a fortune, maybe talking like over $200 but I would like to power my computer, the monitor, my tv, and a small fridge.I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ per watt but if I look up a 20 watt solar panel it is $560 dollars. Why would it not be $20 because they said $ a watt.Where would be the best place to buy the cheapest solar panels?: You are probably better off buying solar cells and making your own solar panel. That is what I plan to do. Figure in the cost of batteries, an inverter, and maybe a charge controller. You will need to test the solar panels to make sure you have enough power to power up everything you have. If not, make additional solar panels, and connect them together. Nevertheless, I think it still might cost way over $200, but I think it is the cheapest way to go.

Q: Can solar panels be used in remote areas with no access to the grid?: Yes, solar panels can be used in remote areas with no access to the grid. Solar panels generate electricity from sunlight, which can be stored in batteries for use during nighttime or cloudy days. This off-grid solar system allows for a reliable and sustainable power source in remote locations, providing electricity for various purposes such as lighting, charging devices, and powering small appliances.
