Solar Polycrystalline Series Panels

Introduction of Polycrystalline Solar 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. Polycrystalline 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.

 

Characteristics of Polycrystalline Solar Panels

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology.

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.Normally Speaking, the poweroutput from 250-300W, the FOB Price is $0.6 Per Watt. The detail price need to negotiate according to further situation.

 

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.

Q:Any recommendation for best solar panels?
If you are looking for the best solar panels, you should know that there are a variety of top manufacturers such as SunPower who make these panels. When shopping for solar panels there are a variety of choices you will need to make including what kind of panels you prefer. There are two main types of solar panels, traditional PV panels and thin film panels. GE solar panels are an ideal choice for residential, commercial or even industrial customers who want to harness the power of the sun. Hope the recommendation is good.
Q:Do solar panels float?
I'd presume they do. They seem flat enough to generate enough surface tension to function as a raft. Not sure if their weight would cause them to sink should the raft capsize though. For what it's worth, there are floating solar panels that are being tested for water-based solar energy plants. The cost per panel is the same as standard solar.
Q:how much money do solar panels cost?
Consider installing building energy measurement first, which cost less than $200. Work out what is using the energy and if there are more efficient options. Consider co-generation which uses gas for an energy input and electricity generation and heat as an output. Use the Solar Energy Calculator to work out how much solar panel area is needed to generate the remaining power needed in you are of the world.
Q:how to make your own solar panels ?
There are several things you’re going to need when making a homemade solar panel, some of the main components include: Solar Cells Wood Plate Soldering Iron Solder Tabbing Don’t worry; special tools are not required for this DIY ‘solar panel’ project, and you will probably have everything you need laying around the garage. and just bind them together.
Q:Price and energy production of solar panels?
The price of solar systems have dropped dramatically in the last 5 years. I would say it has reached to the point that it financially makes sense to go solar! An average home in [California] with $200 monthly electric bill would need a 7.25 kW system to offset 00% of their electric bill (means you won't have to pay anything to your utility company). Average price of the panels are anything between $2,500-3,500 per kW (after 30% Federal Tax credit which might expire at the end of 206). So, average system price will be $7,000-$25,000. If you wanna buy the system your loans monthly payments will be around $40-50 for 2 years and after that your system is paid off and you can enjoy free electricity! Total saving over 25 years can exceed $70,000. Regarding the selection of the right panels or the best company in your area, it varies case by case, city by city. Pick My Solar offers a free service to homeowners to choose the right fit for their home. It's like Expedia or Priceline for residential solar market.
Q:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
Q:DIY home solar panels?
Not worth it unless you can get a fat subsidy. But Congress is working on a bill to provide a significant subsidy, and Oregon may have one as well. A solar plant costs about $0 per watt of installed capacity, and can produce a maximum of two kWh per watt per year -- which is worth about two bits. Without a subsidy, you are better off leaving your money in a savings account.
Q:Are DIY Solar panels legitimate for saving electricity?
I used this youtube video to help me build a 2 volt system. I used this video to build a magnet motor attached to a car alternator, I used an old Ford alternator because they are cheap, then put in the voltage reguialtor that I took out of the same car. I then hooked that up to 6 2 volt batteries in series, then I used 4 500 watt inverters, I got it going about 2 weeks ago, I am waiting to how efficient it will make everything, I also do not have my entire house on it. So far I have hooked up my fridge, deep freeze, 52 plasma tv, and washer. I have not hooked anything else into it yet. I have no idea if it has enough power to turn on full load, like I said I am still toying with it, but it seems to be doing fine.
Q:how much do solar panels cost and r thay worth buying?
Whether you get a check for excess power generation depends on where you live. Some places in Texas will do that, the largest 3 utilities in California will not. The bottom line is that you should not expect solar panels to be a moneymaker. They may or may not be a money saver in the long run, depending on your situation. Solar hot water can pay back in a few years, if it displaces an electric water heater, and if it's in a location that is generally warm. Solar electric usually takes longer to pay back, if ever. The best payback is for those who have expensive electricity already, and are also in a sunny area. As an example, our system cost $2k net, and saves us about $600 / year in electricity (i.e., all our usage). It will take 20 years to pay back the installation cost, but I admit we did it for more reasons than the financial.
Q:Solar Panels, anyone?
Unless you live in an area with a very high UV index, like Las Vegas for example, solar panels are not cost-effective. You definatly should not attempt to install solar power yourself if you intend to power a residence with it (unless you live in a shack). A certified electrician is required in order to connect your equipment to your house's electrical system. It isnt just as simple as a few panels. You need a converter that turns the DC voltage generated into AC. You also need equipment to connect to the metering system for your house. If you want to see if it is cost effective, you will need your electric bills that show usage for a year and the price per kWH. There are a lot of websites that have calculators for solar power systems.
