FAQ

1.Price per watt?

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

2.Parameter of the 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 etc.?

We have two companies(CNBM International & CNBM engineering Co.) with different approaches. We can supply not only the solar module but also Solar Cells, off grid solar system, even service with on grid plant.

4.Warranty policy?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

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

5.Lead time?

In 3 days after purchasing, we will arrange the factory delivery ASAP. The specific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:Solar panel placement idea?
It will generate MUCH more current if placed outside of the window. The best position is pointing directly south. Over the period of one day, you will get the most average sunlight pointing in that direction.
Q:kilowatt solar panel help?
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
Q:what is solar panel? full description needed?
Solar energy begins with the sun. Solar panels (also known as PV panels) are used to convert light from the sun, which is composed of particles of energy called photons, into electricity that can be used to power electrical loads. Solar panels can be used for a wide variety of applications including remote power systems for cabins, telecommunications equipment, remote sensing, and of course for the production of electricity by residential and commercial solar electric systems. On this page, we will discuss the history, technology, and benefits of solar panels. We will learn how solar panels work, how they are made, how they create electricity, and where you can buy solar panels.
Q:How do passive trackers work (for solar panels)?
It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.
Q:How many Solar Panels for my Pool?
I don't think heating a 70,000 gallon pool with solar panels is practical. My husband has designed and built our solar hot water system. It works quite well. We live in Arizona. There's no way we could heat that much water using sun energy. You have to heat the water and compete with the outside air.
Q:Solar panel experiment ?

Q:how much is one solar panel?
no one has answered because you asked a question that cannot be answered. It is exactly the same question as how much is a car?. Do you want a passive solar heating panel, a solar electric panel, .5 Volts, ,000,000 BTUs, do you want just the panel or the panel installed and functioning, or what? the answer is between $5 and $5,000,000.
Q:How much energy does this particular solar panel produce?
The watt is a measure of instantaneous output that can also be used as an hourly measure. volt at amp for hour = watt but also a 00watt bulb requires a 00watt power source, regardless of how long it is on, the 00watts is used as an instantaneous term here. Aircon starts at about 000watts and the new energy efficient bulbs are about 7-5 watts. If you have an electric cooker, that might use 3000 watts, your computer about 500 (very variabke these days though, many are now much lower than this) Your biggest concern would be storage, solar only works when the sun shines so you need a bank of batteries to charge during the day and provide power on demand, they require proper managenemt to ensure ther are charged properly and in turn, an inverter will be required to produce the AC power your appliances will need. It all represents a huge investment with a long payback time and you would still probably need to top-up with a generator during winter, or become ahmish.
Q:Anybody install solar panels themselves?
Hello, okorder.com/
Q:Numbers behind Solar Panels?
For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
