Product Description:

Solar Module Summarize

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer
a wide range of power and voltage, and with high conversion efficiency, and long service life.

Company Description

CNBM International Corporation, as an important external business platform of CNBM Group, plays as a role to export solar products produced by CNBM.

FAQ:

1Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

2When did your company set up?  You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

Q:Solar Panel Demonstration Ideas?
you have the right idea, but forget about so many batteries cause solar power replaces them. get some small solar motors and use them for ceiling fans, try some small xmas light in a box behind a picture to look like a tv screen, use the small solar motor to demo an exercise bike and use a 00 watt or better light bulb to power your solar cells in place of the sun. that would demo the idea best without the use of batteries. i really hates batteries, but i love me some solar. i am a solar engineer and i think that light is the most amazing element in our universe. solar energy was the first source of power on earth and it will be the last. oh, did i mention that it is also so very very free. in fact, solar energy is so free that one can not even buy a handful of it and one can not even steal a pocket full of it. aint that something to think about and to post on your project just for a fun fact!!
Q:how to know the voltage level of solar panel?
A okorder.com/
Q:advice what solar panels to purchase?
If all things are equal buy local. If you are building for a LEED project then choose a manufacture within 500 miles. Another reason to choose a local panel is that if things go wrong there is a better chance of a satisfactory resolution. A no name knockoff from overseas might prove to be difficult to find a few years down the road. One good place to check is the Go Solar California website. They have proof of performance testing on hundreds of panels.
Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q:Kwh and watt conversion-- solar panel cost?
OK, KWH stands for Thousand Watts per Hour. You used ,623,000 watt/hours last month. If you pay $6.00 per watt, your bill would be $9,738,000.00. That's right-$9 million,seven hundred and thirty-eight thousand and 00/00.
Q:How much does a race car that uses solar panel cost?
thats an oxymoron/race car with solar power/forget it/by the by if they start to really harvest the available sources for power the retail price of gas will be 25cents a gallon/
Q:Price and energy production of solar panels?
A small panel will not produce much power. When people put solar electric panels on their house with the goal of saving money, they generally put up a lot of large panels - 200 or 500 square feet worth. Its hard to save money with just one panel. The only way to get close on how much it will cost and whether that represents a savings is to get out your electric bills for the past year, and call a local solar installer for a quote. The system on our house cost $20,000 and we got back $8,000 in incentives, so $2,000 net. It can save money, but that will be over many, many years.
Q:solar panels and electrocution?
Q:I need help with solar panels?
Change the whole piece of solar panel, not just the glass. Looking for solar panel agent in your local city and get one.
Q:I need help finding Solar panels for a boat.?
Rate ,power , voltage and effencicney are four important iterms to choose one battery.
