Solar Polycrystalline Series Panels

Introduction of Solar Polycrystalline Series Panels

CNBM Solar photovoltaic (PV) Panel is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

FAQ

 

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

 

1.       What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2.       Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3.      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.

Normally we put the panels in carton and then in pallets.

4.       Can you do OEM for us?

Yes, we can. It will depend on the quantity.

Q:how much power do i need from my solar panels?
Very simple. Look at your bills from the past year and calculate how much power you used and see what you need to cover that usage. How are we supposed to know how much power you use? Maybe you live in a bdrm trailer or a 6000 sg ft house with 20 kids. Oh and remember a few things. There is more to ' going off the grid ' than just solar panels. When the panels work depends a lot on your climate. They kind of suck on cloudy days or if you live in the artic with 6 months of darkness.Also , you need an area for the (not so cheap) storage batteries. Learn to live by cooking with gas or wood as hydro is limited , so is heat. How do you plan on heating your home /water/ refrigerators and freezers? Off the grid means a lot of compromise. Even the amount of time you can spend on the computer asking these questions. You may be limited to no more than hr per day. Off the grid also includes removing any electronic influence. No cell phones , tv (cable/sat) internet. Grow your own food and live off the land. The amount of solar panels you would need to maintain even a current lifestyle as most of us know it would probably require at least /2 acre and the cost would take at least 5-25 yrs to recover. You really need to spend more time into looking at what the cost versus return is. Like I said before. Look at what you use and see what it takes to get that from your panels. You will be shocked. Currently the panels are very good. But they cannot produce what the average home needs per day every day, they are support systems. Much like a fire place. Now they are nice to have and are very efficient. 50 yrs ago you used to toss in 2-3' logs about 6 around into the only heat source in your home. A fireplace. And it sucked more cold air into the house than the heat it produced. History has a way of repeating itself. This stuff was out almost a decade ago, they just didn`t have batteries then
Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?
How okorder.com Once you know how much you use, and adjust to reduce how much you use, then you have a handle on how much power in panels you need. If you do not mind being grid tied and social engineered, some power utilities have programs to cover some costs of the installation, but still expect to shell out about 30,000 dollars or more, so how long you plan to live at your residence is a factor too. Grid tie is over-rated, but it can be done. To do it legally you need to involve the power company so they can install equipment to shut your equipment off line if they need to work on the power line.
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
Q:Solar panel setup?
The solar panel wires go to the charge controller. The charge controller wires go to the battery. You can also run wires from battery to a load ONLY IF it is DC load. If any AC loads, then you need a inverter to change dc to ac.
Q:Is photovoltaic array another name for solar panels?
Yes or one could say that Solar Panel is a simple and easy way to say photovoltaic array.
Q:Could you have a solar panel in space?
There are thousands of satellites in space with solar panels, but none of them are designed as power stations. Transmitting power using radio frequencies would be profoundly inefficient. A string of satellites orbiting the Earth would be incredibly expensive. Even if solar power were to reach economic viability, we would put them on the ground where we could use them. Given the amount of advanced renewable sources of energy already being developed there is absolutely no reason to launch a power plant into space. Wow - watched the youtube video... that is possible the worst invention ever and I hope it never catches on. The last thing we need are retards who are too lazy to plug in their phones wasting electricity on highly inefficient wireless transfer when many parts of the world are facing energy shortages. Regular chargers are already bad enough because they constantly drain electricity even when not in use. I am definitely not an environmental saint but this thing is just stupid.
Q:how often do you have to replace solar panels?
solar cells never really stop producing, they just reduce their output over the years. There are many solar panels still running at 75% of their initial output and have been up for over 40 years. Most manufacturer will give you a 25 or 30 year waranty. That means that they guarantee that the solar panels will have no less than a 0% drop in the amount of electricity produced by each panel in 30 years.
Q:How may solar panels/wind turbines may be made affordable?
economies of scale or mass production is the answer to just about any item being made cheaper.be it cars or computers or solar panels. Now, how to get there is the question..... market forces? as more people want a 'greener product demand goes up quantity produced goes up unit price goes down....but that takes awhile.... government help ? subsidies...the US gov takes some of your tax money and makes it available as rebate to people putting panels/wind systems in their homes, and establishes policies to companies to take less taxes if they build wind/solar.... government orders: You MUST put in a solar panel ( or we'll send the Green Police to bust you)
Q:do solar panels have to be in direct sunlight?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
