FAQ

We have organized several common questions for our clientsmay help you sincerely

1.what price for each watt?

it depends on the quantity, delivery date and payment terms,

2.what 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.

3.Can 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?

Q:Do you know that China is the largest producer of solar panels in the world?
I visit hundreds of houses a week in my line of work and there are houses in neighborhoods that aren't the wealthiest that have solar. It might be cheaper than you think.
Q:Is there a free solar panel program for veterans?
I had the great pleasure to volunteer with a non-profit in California installing solar panels on qualified low-income households. The homeowners would pay nothing at all or a small portion of the system cost, and all labor was donated. Solar panel manufacturers, like Siliken, Sunpower, and Canadian, and inverter manufacturers, like PV Powered, also offered subsidized or discounted pricing. The rest of the cost of the panels was funded by the Single Homes Affordable Solar Homes (SASH) Program run by California’s Solar Initiative. The nonprofit is named Grid Alternatives and I included a link to their site below.
Q:What is the real cost of Solar Panels?

Q:SOLAR PANELS (sun enerjy)?
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:where can i get a small solar panel to power an outdoor water pump?
More okorder.com/... (... or search portable solar panel) And probably under a tree isn't a good placement for a solar panel. Good luck!
Q:Why are solar panels so expensive?

Q:solar panel for pool pump?
Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.
Q:What are the properties of Solar Panels?
Properties Of Solar Energy
Q:2 Questions on Solar Panels?
Solar panels are available in a wide variety of power ratings.  Energy is the sum of power over time, so how much energy a panel produces depends on the intensity of the light hitting it and how long it's applied. I understand that current single-crystal silicon PV panels are warranted to produce ~85% of their rated output for 25 years.  Most will do better, and will produce useful output for perhaps 50 years or more.
Q:How can I regulate current from a solar panel?
Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
