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.

6. Can you do OEM for us?

Yes, we can.

7.How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:What factors effect the amount of electricity produced from solar panels?
irradiance in watts/meter^2 (000-800w/m^2 depending on air quality) COS of angle to the suns rays efficiency of the panels (usually about 5%) age of the panels(one dead cell can drop an entire panel from the array) how dirty are the panels (dust, bird poop, leaves, shading) efficiency of the inverter (usually about 90%) All of these factors affect the amount of electricity produced. One other consideration is that in areas of extreme hot and cold the band gap of the silicon is changed.
Q:Are solar Panels worth it?
Solar panel systems are one of today's best investments! What other product can you get that last for 25 years or more and saves you money every day of the year, but pays itself off in 5 to 0 years in most cases. Our company has installed well over 00 solar panels systems for clients who have declared independence from their utility! Contact us to learn more if you are in the Northeast US.
Q:how can i optimize power in a solar panel?
first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
Q:How much energy would this solar panel produce?
The world record efficiency for a solar panel is about 42%. At the equator, you can get up to about 000W m^-2. The efficiency of commercial cells tends to range from 0-20%. They're almost all single junction cells, so will never exceed 3% efficiency. To work out your maximum power output, multiply 000 x efficiency (as a decimal) x area covered. So an 8m x 0m solar panel would be 80 square metres. At 5% efficiency its peak output would be 2000W or 2kW. Total energy output will be different, since it won't be maximum power output all the time. In fact, it will more likely generate something like 20% of its maximum theoretical output, since the Sun won't always be overhead (and sometimes it's night!). The 2kW panel above might have a mean output of 2.4kW, or 57.6kWh/day.
Q:what is the cost of a solar panel
I think Brian's answer was perfect for the US, but in the UK, with very high gas and oil prices, we would also look at hydrogen production from the wind turbine instead of a battery store, where excess capacity could be used to heat the house or potentially act as a car fuel. Alternatively we would look to selling back excess electricity to the grid.
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:How do you set up 30w solar panel?
must be one of the place who's place have sun
Q:Solar Panel Charging?
You're right. The solar panels must produce a voltage equal to or slightly greater than that of the batteries. So you need to either switch to a 2 volt battery or add two more solar panels of the same current rating.
Q:solar pannels capacity?
Well Capacity is totally depends upon quantity of panels and size of panels. You can install panels according to your requirements.
Q:What home appliance can be powered by a solar panel?
that's going to take approximately $forty 4,000 to place sufficient photograph voltaic panels to furnish the comparable quantity of skill which you at the instant have coming from a 220 v a hundred amp skill line on your place. you additionally must understand which you truly want some approach of storage for use at night or dark days. this might upload yet another $7,000 to the fee. the only actual answer for the skill issue is nuclear skill.
