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.

Q:how much money can I make a year for the electricy I sell from a solar panel?

Q:background of solar panel?
Photovoltaic cells work because of the photoelectric effect. However, a solar panel can actually be using several different technologies that have the same common effect of generating electricity when the sun shines on them.
Q:Will my 8watt solar panel charge a car battery and how fast?
welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
Q:How many solar panels?
Create okorder.com
Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
well the thing to remember just like any rechargeable battery they don;t respond well to continues charging they need some down time to discharge and then recharge. during the charging process the liquid or battery solution get hot and even evaporates. Replacing the battery solution with water won't work when your battery has lost it's solution you need to get battery acid replacement or battery repair solution. this is sold in many location near where the batteries are sold. check your spec for your solar panel out put and take those specification to your local auto store and they might even suggest an over sized battery. you might consider adding an additional battery in series for additional power storage.you might also using a light sensor and cut off switch solenoid which which stop charging or which would also stop and current from returning back to the panel. if you have every own a small car the battery is much smaller than that of a pick up. be sure that you don't get the small battery look for a large heavy duty battery all sold in the same store.
Q:I want to buy solar panels?
If okorder.com and search for solar panels, they list companies that sell solar panels and you can compare prices there.
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:Reflectors or mirrors around the solar panels.......?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q:WHAT ARE THE SOLAR PANELS ON POWER POLES?
Here is an article about this. They use the poles (which they already have) and install power panels, the electricity is given into the grid. There are companies in NJ which use google earth to find buildings with large roof tops (imagine all the warehouses !), contact them and lease the rooftops to install solar panels, there a different ways how to finance that (by them, by the company, ....) and they sell the electricity into the grid and receive a certain price for this. Usually the refinancing is 5 - 7 years of the investment, after this is profit for additional 5 - 20 years. Walmart had a project to put solar panels on the super centers ....
