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)

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.

⑥ Can you do OEM for us?

Yes, we can.

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q: How do solar panels affect home resale value?: Solar panels can increase the resale value of a home due to their potential cost savings and environmental benefits. Studies have shown that homes equipped with solar panels tend to sell faster and at higher prices compared to similar properties without solar installations.

Q: i have to do a science fair project and thought it would be cool to make a solar powered vw bus. i have 2 6volt solar panels to power a dc motor that works off of 9v 2v or 8v. i also bought a 2nd motor because the first wasnt workin for us. this one is a 3v motor. ive had them in the sun but they wont work. please help, thanks: Make okorder

Q: What is the difference between solar panels and light panels?: The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.

Q: What is the impact of tree shading on solar panels' efficiency?: The impact of tree shading on solar panels' efficiency is negative as it reduces the amount of sunlight reaching the panels and therefore decreases their energy production.

Q: Can solar panels be installed on a library or educational institution?: Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions are increasingly adopting solar energy systems to reduce their carbon footprint, lower energy costs, and promote renewable energy education. Installing solar panels on rooftops or open spaces of these buildings can provide clean and sustainable electricity, benefiting both the institution and the environment.

Q: Can solar panels be installed on a canopy or pergola?: Yes, solar panels can be installed on a canopy or pergola. In fact, these structures can provide an ideal location for solar panel installation, as they offer ample space and optimal sunlight exposure. By integrating solar panels into canopies or pergolas, you can generate clean and renewable energy while simultaneously providing shade or protection from the elements.

Q: i would like to hook up a power outlet to a solar panelmy light system is 500watts will run for 8 hours/day between noon to 8PM.So what is the most effective system do I need?: You CANNOT directly hook up anything to your solar panel that is ac as your solar panel is dc. You need several things in order to make it work correctly. I have put up a small diagram of how basic solar works and have included a link below where you can see it. Then if you have further questions, I will be more than happy to answer them for you if I can. Thanks Rock

Q: I have a question about solar panels. What are the benefits of this system if I installed in my home. for example i know it produces electricity but does it do anything else? How many panel would you guys think I would need for 2000 sq ft. do you know if it produces hot water? Thanks for your help: Grid-tied solar systems in the U.S. run at least $8/watt installed. To completely run a 2,000 sq ft home, you'd need about 50 amps service from solar -- both 20 volts and 240 volts. Not very practical. Panels are expensive, but the BOS (balance of system) is as well. You need mounts to bolt the panels to the roof (same thing if ground mounted). Cable, wire, and connectors will run several hundred dollars. A couple of grid-tie inverters in the range of 4,000 watts each will cost you several $6,000 to $8,000, plus sub panels, combiner boxes, breakers, disconnects, charge controls, and batteries, among other things. You'd likely need 5 to 24 panels, depending on too many factors to mention here. You'd need at least 8 batteries, likely 2 volt ones, probably more if you want to run the entire home from solar. Solar (or wind) systems have to be installed in the U.S. by state licensed installers, and there are not many of those yet. And if you grid-tie the system, you'll need to put an interconnection agreement in place with your local utility, plus the utility will have requirements on the net-metering and installation of a switch they can use to turn your solar system off from the grid. And this would not produce hot water in the way you are thinking. If you have an electric hot water heater now, the solar system could help run that, just like the rest of your home. Hot water from solar and electricity from solar are two completely different technologies.

Q: Can solar panels reduce electricity bills?: Yes, solar panels can reduce electricity bills. By harnessing solar energy to generate electricity, homeowners can offset a portion or even all of their electricity consumption from the grid, leading to lower electricity bills.

Q: Well, I am looking for a cheap way on building a solar panel, instead of buying by the manufacturing stores. I would like to stay in the budget up to ,000 dollars. I want to have Solar Energy for my house because the sun is always shining. Is there a way I can make the Light power some of my house? What would I need? How much time would it take?Where can I get the items I need?: The panels themselves- no. Minimal. For most it is just hosing them off with water as needed to remove dust. Battereis on the other hand are usually needing attention every week to maintain the electrolyte levels. The exception being AGM types. Periodic desulphating may be needed on older setups, but beyond that keeping chickens are more demanding. Batteries are how you store your energy for periods when demand exceeds what the panels can deliver, and at night. How many varies. Factors of how you use energy has most impact. Some people can get by with a few hundred Watts, for others 3 to 5 Kilowatts are needed. For the average American, 5 to 7 Kilowatts as a minimum without some serious changes to how energy is used.
