FAQ：

1.Price per watt?

It depends on the quantity, delivery date and payment terms.

2.Parameter of the module?

We have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

3.Can you provide the peripheral products of the solar panels, such as the battery, controller etc.?

We have two companies(CNBM International & CNBM engineering Co.) with different approaches. We can supply not only the solar module but also Solar Cells, off grid solar system, even service with on grid plant.

4.Warranty policy?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

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

5.Lead time?

In 3 days after purchasing, we will arrange the factory delivery ASAP. The specific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q: is this fact true? - its a limitation to solar panels during summer when it's in extremly hot countrie. I've heard it from my science teacher .. please give detail if you have any and any more benefits/limitations is welcomed .. Thank you :) !: Solar okorder /... you'll notice that they have different curves for different temperatures. But they do still produce power, certainly. I have an array on my roof, and it still manages to max out the inverter on a hot summer day. But I do notice that the top row, which is hotter due to heat rising from those below, consistently puts out a few less watts than the bottom row. So more sun is certainly better; direct light is exactly what's needed. But hot panels due to poor air circulation or high ambient temperature does cut into efficiency. (Solar thermal, of course, is a different story)

Q: Can solar panels be used in commercial buildings?: Yes, solar panels can definitely be used in commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops or in open spaces to generate clean and renewable energy. This helps reduce their reliance on traditional grid electricity and lowers their operational costs in the long run. Additionally, commercial buildings often have ample roof space, making them ideal for maximizing solar energy generation.

Q: Can solar panels be installed on a flat roof?: Yes, solar panels can be installed on a flat roof. However, it is important to consider the orientation, tilt, and shading of the roof to ensure maximum efficiency and productivity of the solar panels.

Q: My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 2volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under $20. I was just going to go to ecology and just pick up some used batteries but I may be wrong.Any help for a first timer might help me and my gramps out will be appreciated.Thank you: Solar charger employs solar energy to supply electricity to devices or charge batteries. They are generally portable. Solar array: electrical device consisting of a large array of connected solar cells Solar Panel is a group of solar cells arranged into a panel that can be installed onto a flat surface. The panel captures sunlight and converts it into DC power.

Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.: Not that simple. The N E C covers electrical systems and your state utility regulators cover what and how you can do it. As a practical consideration the inverter produces power and would have an outlet to tap it. Possibly a standard convenience outlet that is the same as your house devices. The problem is to provide a cord that does NOT have exposed hot conductors when it is plugged in and how do you isolate the system from the power grid. To do this you need both a reverse service device and transfer switch that will isolate the house from the grid while the inverter is operating.

Q: What is the role of inverters in solar panel systems?: The role of inverters in solar panel systems is to convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity, which is the type of electricity used in homes and businesses. Inverters also ensure that the AC electricity produced is synchronized with the grid, allowing for efficient utilization or storage of energy, and enabling solar panel systems to feed excess electricity back into the grid.

Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?: In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.

Q: Can we cover up solar panels on our house with regular siding?: oh my goodness. make the investment aand update them

Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.: I wouldn't worry about what the solar panel is going to do to the surrounding environment, I would worry about what the surounding environment is going to do to the solar panels.
