FAQ

We have organized several common questions for our clients,may 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?

Our product performance guarantees for 25 years

 12 years guarantee for workmanship

 Timeliness of delivery

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

5.How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Q:Anyone know if there is a solar panel that you can travel with that is not USB plug in ?
Solar panels require a charge converter before it can be used by an AC source. There is no direct solar panel with built in charge converters that I know of because, when purchasing panels, you must purchase the wattage requirements of the job (this can be several panels linked), and a charge converter that will handle the <? panels required. A chain of stores up here in Canada have a portable battery pack that has a solar panel to increase its charge capacity or duration, but its not something you would want to lug around for long periods of time, because is weights in about 3 lbs.
Q:Solar panels don't work when it's too hot/sunny?
Solar okorder.com/... you'll notice that they have different curves for different temperatures. But they do still produce power, certainly. I have an array on my roof, and it still manages to max out the inverter on a hot summer day. But I do notice that the top row, which is hotter due to heat rising from those below, consistently puts out a few less watts than the bottom row. So more sun is certainly better; direct light is exactly what's needed. But hot panels due to poor air circulation or high ambient temperature does cut into efficiency. (Solar thermal, of course, is a different story)
Q:How can I make a sun tracker for a solar panel?
Since the sun moves in the sky on a very predicatable course you don't need a closed loop control system to track it. All you need is a clock-drive motor and the proper gearing for your latitude. The clock drive motor will move at a constant rotational velocity based on time, and when it is geared down properly the angle of the shaft will follow the sun. Make sure the clock motor is powerful enough to move the solar panel, etc. That's a start, anyway. .
Q:Has anyone used portable solar panels for home use?
portable panels are too small to be much use for a modern household. A panel appx 20 inches square might supply a laptop computer... but it won't keep your refrigerator running.
Q:Why do solar panels stop working?
The plastic covering degrades slowly and becomes more opaque, The metal current carrying parts corrodes over time. The metal frames corrode but can be repaired. The photovoltaic cells also degrade over time from exposure to ozone and heat that builds up in the panel.
Q:Why should people use solar panels more for houses?
Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
Q:When you get solar panels do you connect them to the grid?
You okorder.com/ as they provide very accurate free solar quotes and break down all the incentives you will be eligible to receive, your estimated annual savings, your payback period, projected IRR, and a cash flow analysis. They taught me everything I know about solar, and I must say they're a great starting point if you're curious about what solar energy is all about.
Q:Homemade Solar Panels?
I okorder.com/. It's a pretty basic article that gives you the gist of it.
Q:Making solar panels bad for the environment?
Like any other materials, solar panels need to be manufactured. These components are usually imported, they use energy to produce and transport. However, once you install solar panels, they need little or no maintenance (except cleaning to maintain efficiency) and they use no other resources to produce power. Over their lifespan, they'll produce more energy than was used to be made, so on the whole good for the environment.
Q:What does it mean when a solar panel is 00w?
The 00w panel puts out 00w at peak power -- full sun. You will lose some power as heat through wires and other equipment and also some will be lost when it's converted to AC, unless you will be using all DC appliances and lights, etc. I think a good estimate would be about 0 - 5% loss. You will also need to know your average solar insolation, average amount of full sun you receive at your site. This will tell you how many panels of 00w it will take to get you 5kwh/day. Don't forget your losses as per above and add a little extra for peak usage that is needed when two or more major appliances and power uses start at the same time. Hope this helps. I'm glad you're checking into solar and good luck.
