Introduction of Poly solar panels CNBM
Polycrystalline Solar Panels 265W With High Efficiency
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.
Feature
1.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
3.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
4.Long lifetime: ≥25 years; Less power decrease.
5.Resisting moisture and etching effectively, not effected by geology.
6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

- Q:Can solar panels be used to power swimming pools?
- Yes, solar panels can indeed be used to power swimming pools. Solar panels can generate electricity from sunlight, which can be used to operate pool pumps, heaters, and other equipment, reducing the reliance on traditional electricity sources and saving on energy costs.
- Q:How do solar panels affect the property's resale time?
- Solar panels can significantly impact a property's resale time by reducing energy costs, increasing the property value, and attracting environmentally conscious buyers.
- Q:Can solar panels be installed on a balcony or terrace?
- Yes, solar panels can be installed on a balcony or terrace as long as there is sufficient sunlight exposure and structural support in place to hold the panels securely.
- Q:I am looking at building my own solar panels to at least help cut down the rising energy bill. I know its expensive. I already have the solar cells so no need to worry about listing that. But i am looking at wiring it directly into the house. Is there any parts that you could list for me, that would be great. thanks
- You're missing a few assumptions: - where on the globe? - how well is your house insulated, how do you plan to heat/cool your house? - why do you insist on power wasting appliances like plasma screens? Usually, unless it's absolutely impossible, a grid-tie-in system is much better than an insular system. You could use the grid to 'store' electricity for those times when the sun isn't shining and as fall-back if your yield isn't quite as good as you calculated. With the battery system, you'll have to specify your reliability requirements. If you want a 00% guarantee that you'll always have electricity, even if the sun is not shining for a week longer than you've planned according to the past weather history of your area, you'll either have to ridiculously oversize your battery (and panel) system, or plan for some sort of backup system anyway. Finally, if you're really planing such a system, you might want to take a look at the fridges and freezers used on sailboats: these use a eutectic cold accumulator, i.e. you 'charge' the fridge when the engine is running (or the sun is shining) and it'll then keep the temperature for another ~2...35 (professional systems) hours.
- Q:I need to have more information about what are solar panels. will you help me?
- Solar panels are made up of lots of solar cells. They don't give loads of energy. A line goes around the cells and... that's all I know lol
- Q:Can solar panels be installed on a factory or industrial facility?
- Yes, solar panels can be installed on a factory or industrial facility. In fact, many factories and industrial facilities are increasingly turning to solar power as a sustainable and cost-effective energy solution. Installing solar panels on such facilities can help reduce electricity bills, decrease reliance on fossil fuels, and contribute to a greener and more environmentally-friendly operation.
- Q:Can solar panels be installed on a rented property?
- Yes, solar panels can be installed on a rented property. However, it is important to check with the property owner or landlord before proceeding with the installation. Some landlords may have restrictions or specific guidelines for installing solar panels, while others may require written permission. It is recommended to discuss the matter with the property owner and potentially reach a mutually beneficial agreement.
- Q:I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
- The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
- Q:Hi, i want to please a solar panel in Lima Peru, my Latitude is -2 and longitude -77. I understand that since i am in the southern hemisphere, my panel should be pointing north. However, i am using a program called pvdesigner, and according to this, y should face my panel with and azimuth of 00degrees (0 = south) and a tilt of 60degrees. Does this make any sense?thanks
- It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
- Q:i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
- Graminoids are among the most versatile life forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife and organics. Graminoids are the dominant vegetation in many habitats, including grassland, salt-marsh, reedswamp and steppes. They also occur as a smaller part of the vegetation in almost every other terrestrial habitat. There are some 3,500 species of graminoids. Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle, sheep, horses, rabbits and many invertebrates, such as grasshoppers and the caterpillars of many brown butterflies. Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. In the study of ecological communities, herbaceous plants are divided into graminoids and forbs, which are herbaceous dicotyledons, mostly with broad leaves.
