5.FAQ of Solar Module

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

what price for each watt?

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

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.

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.

Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.
Q:How can you get affordable Solar Panels?

Q:Need isntructions for solar panel diy?
This is my system: Solar Panelcharge controllerBatteryInverterLights. Keep positive to positive, negative to negative. The solar panel has a cable that has a polarised two pin disconnect (more or less takes care of itself), as does the harness that connects to the battery, a couple of extension cords, and the charge controller itself. The harness in its current install is fixed to the inverter DC in studs, which has a cable that is fixed to the battery. The harness also had a fuse holder and 0A fuse. Except the battery, panel, and lights themselves, all the works are in a mostly sealed box with only panel, battery, and AC cables leaving. The mains voltage lights (about 3x23W CFL) are connected to a power inlet, which is linked to the inverter power outlet with a short cord. The lights are controlled by turning the inverter on or off with its control switch. The inverter is a 400W cheapo, battery 36Ah AGM, panel 20W, controller basic 7A.
Q:Solar Panels question?
maybe you ought to ask a solar installer in your area. who knows what the electric rates are. and how much electricity you use. and how much sun there is. and what your electric utility's policy is. and what kind of house you have, and how you use electricity. and what appliances (eg stove) you might convert to electric to take advantage of solar panels. wouldn't that seem to be a good idea?
Q:how to make a solar panel without any kit?

Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:How much money does it cost to make ONE solar panel?
Have okorder.com . Possibly this could immediately instruct each and every one!
Q:How to make electricity from the sun without using solar panels?
There are a couple other methods under development. One uses a fan inside a cooling tower and a large area covered with black tarps. The heated air can only escape through the cooling tower in the center of the site. The air movement turns the fan blades that spin a generator. Another solar generator uses mirrors that track the sun and focus their energy on a large pipe. I don't recall the contents of the pipe, but the superheated material is used to boil water generating steam to spin a turbine/generator. Neither of these are small scale projects, and are probably far more expensive than what you're looking for.
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
