FAQ

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

①What price for each watt?

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

②What 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.

③Can 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 the off grid solar system, we can also provide you service with on grid plant.

④What is your warranty system?

 Our product  performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

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

Q:Tips for convincing my school to put solar panels on the schools roof?
When okorder.com/ Good luck but the best way to win is to find a way to get it done and then they can't say no.
Q:What is the principle and structure of solar panels?
solar panels: solar panels is the core of solar power generation system, solar power system is the highest value of the part. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store, or to promote the load work.
Q:What does it mean when a solar panel is 50 watts?
Volts x amps = watts, so depending on what you want to run or charge will have to be taken into consideration. For example if you have a 0 volt TV @ 2 amps, then you're going to need 220 watts to power that. Best way to find out what it's volts and amps are, is to look on the back of the TV. But for batteries it doesn't matter, cause all batteries are is stored power, that can be later used, just use an inverter on them to convert DC to AC, also use a charger controller between the solar panels and the battery, cause you don't want the Solar panels to overcharge your battery and totally **** it up ______________________________________ But the more watts, the faster the power is returned; less watts, longer times. .
Q:How can a solar panel work for me?
Sounds okorder.com.. I've seen the particular device listed there. While the lamp is mediocre for an LED light source, the panel is excellent - real polysilicon wafers, in an aluminum frame. Same construction as the kind of panels in commercial installations.
Q:Single Solar Panel savings?
I am afraid you are in for some disapointment. A typical solar panel might put out something over 00 watts, and cost a pretty big bundle. Then, what would you do with the power? It will be low voltage DC. You could charge a battery, or run a DC appliance. You would get less than ten cents worth of electricity per day. If you wanted to use it for household appliances, you would need an inverter. More big bucks. Type solar panels in the green search box at the top of this page, and read previous Q A. Also do the same on the Internet. Sorry to be a wet blanket.
Q:How to wire solar panels?
I'll add a few comments to Teelo's It may not be good to connect the assembled solar cells directly to the battery. When there is no sun I think it will drain the battery. I'm pretty sure all circuits I have seen have a reverse polarity diode in series. (unless Teelo knows for sure). Hmmm Reminds me that I have some bare solar cell elements from when Motorola was making them. I used some to power a small radio controlled car. I do know that all good applications have a regulator to make sure the charging is done properly
Q:solar panel environmental affects?
You would need to consider how much sun your area gets on average. You would need to do a cost/benefit analysis to decide if you will be saving money eventually. Environmentally, it would not affect the plants or animals around it, except those it might block the sun from. Meaning, the grass growing in the shade of the panels will probably die out, but that goes for anything that would cast shade for the majority of the time. Solar panels are simply rechargers for the batteries it's hooked up to. No different than a cell phone charger affects the area, people or plants around it. If it is a worry, make some orgonite and place it around the panels. :)
Q:automated way to clean solar panels?

Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
