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

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.

Q: I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?: Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.

Q: Can solar panels be used in commercial buildings?: Yes, solar panels can be used in commercial buildings. Many businesses and organizations are incorporating solar panels into their buildings to reduce energy costs, decrease their carbon footprint, and take advantage of potential tax incentives or subsidies. Commercial buildings have ample roof space to accommodate solar panels, and with advancements in technology, solar panels can be integrated seamlessly into the building's design.

Q: Can solar panels be used in urban areas with limited space?: Yes, solar panels can be used in urban areas with limited space. There are various options available such as rooftop installations, vertical panels, and solar canopies. These solutions maximize the use of limited space and allow urban areas to harness solar energy efficiently.

Q: Can solar panels be used to heat water?: Yes, solar panels can be used to heat water. Solar water heaters use the energy from the sun to heat water, typically through the use of solar thermal collectors. These collectors absorb solar radiation and transfer the heat to a liquid, which is then circulated to heat the water. This renewable and environmentally friendly method can be used for residential and commercial purposes to provide hot water.

Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true): Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.

Q: How much energy can a solar panel produce?: The amount of energy a solar panel can produce depends on several factors, including its size, efficiency, and location. On average, a residential solar panel system can generate anywhere from 10 to 20 kilowatt-hours (kWh) of electricity per square meter per day. However, this can vary significantly based on sunlight availability, panel orientation, and weather conditions.

Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt: You okorder / Solar Pro Magazine another of their publications

Q: Im curious because I read about a boy who invented a 3d solar panel, using a pyramid he designed a solar panel that collects light more efficiently. Now I have a question. Why cant I design a solar panel that takes adventage of convex and concave mirror's and use a surface that collects light and then focus's the suns energy into a beam and take the beam into a chamber where the solar panels are sitting and surround them with mirrors as well, so any light not obsorbed by one particular spot is reflected to another area for reabsorbtion. I know solar panels dont absorb light but perhaps that will allow more light to create the effects it needs.: I okorder /

Q: Can solar panels be installed on a commercial building?: Yes, solar panels can be installed on a commercial building. In fact, many businesses are opting for solar panel installations as a way to reduce energy costs, promote sustainability, and take advantage of government incentives. Commercial buildings provide ample space for solar panels to be installed on rooftops or as ground-mounted systems, allowing businesses to generate clean energy and contribute to a greener future.

Q: i also need to know how does a solar panel work: solar panels work in an interesting way. light is absorbed by each solar cell, and light 'photons' bump into electrons to produce 'voltage'/power. the process is naturally called the 'photo-voltaic effect'. the loose electrons are captured by an electrical conductor in the solar cell (usually made of silicon) and a circuit is completed ... solar panels may generate more power than is actually needed. this extra power is simply stored in lead-acid batteries (they store upto 000 watts). read more about it here...
