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:im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.
The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
Q:Can solar panels be used for heating water?
Yes, solar panels can be used to heat water through the use of solar thermal systems. These systems utilize the sun's energy to heat water directly, providing a sustainable and cost-effective alternative to traditional water heating methods.
Q:Can solar panels be used for powering outdoor lighting?
Yes, solar panels can be used for powering outdoor lighting. Solar panels capture sunlight and convert it into electricity, which can then be stored in batteries. This stored energy can be used to power outdoor lighting fixtures, making them independent of the grid and environmentally friendly.
Q:Can solar panels be used in areas with high levels of shade or obstruction?
Solar panels are not very efficient in areas with high levels of shade or obstruction as they rely on direct sunlight to generate electricity. However, there are certain technologies and panel designs available that can still produce energy in shaded areas to some extent, although their overall efficiency may be reduced.
Q:I want to purchase some or one solar panel for my home. I don't know where to buy them from. I've loooked online and if i could buy them online that would be best, but if you knew of a website that has good prices than that would be great!Thanks

Q:The colder a solar panel gets the more efficient it seems to be. As the panel warms, it loses some efficiency. Why is this so? Please explain in a way you would expect a high school kid to understand it, as I am a high-schooler and i have to explain this to other high-schoolers.
For water heater type of solar panel the hot panel has more radiation losses reducing the heat available to be transferred to the water. In PV panels it has got to be characteristics of the PV cells. If the conversion efficiency drops with temperature rise then only this can happen. PV=photo-voltaic
Q:trees vs solar panels who would win?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:Was at home depot today and a Solar City sales man came up to me, offering me free solar panels. He said he could install them on my garage for free, free installation, free panels. Promised me it wouldn't cost me a dime. This is obviously appealing to someone like me who has a $200.00 monthly electrical bill. Now my question is this. Is this a scam? Are there ANY hidden fees or things I should be weary of?- I understand I may not save tons of money, but if I can save even something as low as $20 a month I would be happy. I live in a sunny area and they seem very interested in my garage roof. Any information would be super-helpful, thank you.
Remember, if it sounds to good to be true, it usually is .
Q:Can solar panels be installed on a theme park or tourist attraction?
Yes, solar panels can be installed on a theme park or tourist attraction. In fact, many theme parks and tourist attractions around the world are adopting solar energy as a sustainable and cost-effective way to meet their power needs. Solar panels can be installed on rooftops, carports, or even as ground-mounted arrays in open spaces within the park, allowing these attractions to generate clean energy while reducing their carbon footprint.
Q:I know that the Solar panels store the power from the sun in the daytime, where does that stored energy go from there? Is it stored in the batteries? And how would you keep the batteries topped up if you had no Electric? by a generator? interested in solar panels for abroad, but need more info.
solar panels collect the suns energy and turns that into electricity that is then stored in batteries. attached to the batteries is another device that takes the power from the batteries and turns it into power you can use in your house. it is a very expensive power alternative.
