Solar Polycrystalline Series

 

 

Introduction of Solar Polycrystalline Series

CNBM Solar photovoltaic (PV)module 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.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

 

Characteristics of Solar Polycrystalline Series

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.

IVAI 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. .

Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
It uses the nuclear decay of plutonium in a 'Radioisotope Thermoelectric Generator, or RTG. The heat of plutonium decay is captured and converted to electricity. Pioneers 0 and , Curiosity on Mars, and other deep-space probes use this, as the sun's light is too dim to use solar panels.
Q:where to buy solar panels?
You need to be more specific about what type of solar panel. ) PhotoVoltaic (produces electricity) 2) Fluid (Glycol) (heats water or air using a heat exchange tank) 3) Fluid (Water) for pool water heating
Q:H2 as an Alternative Fuel Source using Solar Panels?
Currently solar panels are rated at about 5 percent efficiency. That means that about 85 percent of the solar energy that is falling on it, is wasted. Electrolysis is also about 67 percent efficient. So the TOTAL amount of solar energy you would have converted into hydrogen is 67 percent of 5 percent. Using my calculator that comes out to: about 0 percent total efficiency. About 90 percent of your solar energy gets wasted in the process. A better alternative to solar panels would be solar powered sterling generators. Sterling engines are EXTERNAL COMBUSTION engines, like the old fashioned steam engine, and can be run off any heat source - including the sun. Heat from the sun is focused using parabolic mirrors, and the efficiency of a sterling engine / generator combination is rated at about 30 percent. Your TOTAL efficiency - both solar sterling and electrolysis combined - would be around 20 percent. If you are dead set on using hydrogen? Even though there are better alternatives? Such as alcohol? Then I would suggest storing it in titanium dioxide pellets. This way you can store the hydrogen, without it being in danger of exploding. You can ALSO ram a hydrogen container like this into a solid brick wall. Once again? Without fear of an explosion. Numerous studies have been conducted on this. As for controlling the exact measurements? Nothing in the air-fuel ratio of a car - - or the timing - which you are also going to have to change - needs to be exact. A good enough approximation will do. As for how you get your measurements? You need to compare the density of gasoline vapor with hydrogen gas. A comparison of the molecular weight of gasoline - - as compared to the molecular weight of hydrogen - should get you started in the right direction for this.
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q:Homemade Solar Panels?
a solar hot water heater is not a solar panel that makes electricity that runs your hot water heater.....it is merely a long tube or pipe, bent back on itself so there,s, say 00 feet in a 2foot by 4 foot space; it's in a framework and under a sheet of glass or plastic; You put out in the sun and it captures heat.....ever notice how hot the water is coming out a garden hose that has been left out in the sun in summer? Same idea.. we have used them here in the islands for years and they work great. Even up north, a solar hot water heater that preheats the water before it goes to a traditional water heater should work fine.
Q:anybody got any info on solar panels for energy savings?
. Solar panels are expensive. It will be a long time before you 'save' money. 2. My sister-in-law and her family have solar panels. The put them in about 7 years ago and are still recouping the costs. 3. I'm sure that there are web sites that can give you info on solar panels. Look them up for yourself. 4. I'd give you more answers, but my hamster-powered generator needs a potty break.
Q:How do solar panels and their battery backup systems work?
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
a 0w solar panel means at peak efficiency ( high noon, panel pointed flat at the sun, hitting it at 90 degrees), you will get 0 watts (at any given second). Watts = volts x amps a 2volt battery needs an incoming current of at least 3 volts to charge it; 3.5 volts is better. so if the output VOLTAGE of the panel is less than 3 volts it wont do anything. Even if it is, 0 / 3.5 = .74 amp.( three quarters). It will take forever and a day to charge a deeply discharged deep cycle battery.......... consider that a small 0v battery charger is putting out 3-5 amps ( or 3 x 0 =330 Watts) and the alternator on a car is putting out 20 to 50 amps at 4 volts ( 280 to 730 Watts).
