Specification of  Solar Polycrystalline(270W-290W)

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 Polycrystalline Silicon Solar Panel

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.

IX.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:How can I be part of the solar panel industry?
Manufacturing your own electrical solar panels is out of the question. They are built much like computer chips and setting up a plant to do this would cost millions of dollars. You could become a solar system installer. These businesses install solar systems on homes and are paid for this service. You will need a significant amount of technical training to do this though, I would guess at least two years (the last thing you would want to do is damage someones home or design a system that is dangerous). I would suggest that you go into business making energy improvements to homes that do not involve solar energy. Most people can get the best value for their money by improving the air tightness of their homes (several tubes of well placed caulk). Other things you could offer would be the upgrading of door, Windows and electrical box seals. Insulation jackets around hot water heaters is also something a small firm could offer home owners. Other energy improvement are also possible and you could offer a whole shopping list of improvements to a customer. Good luck
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:how do i pick out solar panels to match my battery bank?
I don't know where you got the idea you have 8 hours of sunlight. Assuming clear skys and no dust, forest fires, clouds or other impediments, the average sunlight available in North America averages out to approx. kw/sq. meter. That's the maximum available, at midday. Multiply this be the efficiency of the cells (I assume about 0%) and it means about 00 Watts/sq m. Since you have said you have a tracking system, this works out to about 00 * .344 * 2 = 43W/h per day (per sq. meter).
Q:What size and watt solar panel?
I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
Q:Cost and energy generated by solar panel?
A little more than 0 watts per square foot, so that size panel would generate 250 watts under ideal conditions, which is noon on a sunny but not too hot day, near the equator. That's about /3 horsepower, or the same power as a man working hard. That is larger than needed to keep the battery of the car charged, unless you plan to run a laptop or something off it at night. The power is also too small to power the car for driving. If it's an electric car, you could get maybe another 2 miles per day out of the car, again, under ideal conditions. An RV store might have an idea of how much installation would cost. They would be accustomed to solar panels for RV's, but probably not small cars. A panel of that size would cost perhaps $500-800 just for the panel.
Q:Questions about charging batteries via solar panel...?
A solar panel to charge a 2V battery has 36 cells in series. This allows for temperature of the panel up to 60°C, and the maximum required charge voltage. For a 24V battery, 2 panels in series. A 24V battery requires around 28-29V, but look up your battery data sheet to be certain. A specialized converter using electronics could charge a 24V battery with a 2V panel. The system voltage is controlled by the battery unless the battery is faulty. The 2 panels in series could be 42 volts no load, but the battery pulls this down to whatever is required by the battery. This is because the panels are a current source, the current is determined by illumination, and attempts to draw more result in reduced voltage. Even a short circuited panel delivers approx. the same current with no voltage. The battery voltage varies from around 20V (really flat) to around 28V (really charged). A 30W panel is around .75A, considering the optimum panel voltage for power is around 7V for 36 cells. This is small compared with what you are using. The battery wastes about 30% of the power, in chemical conversions. The time to charge it is 4h at the 0h rate, which is Ah/0. (i.e. ampere hours)
Q:how does solar panels give power to the batteries?
solar panels work in an interesting way. light is absorbed by each solar cell, and light 'photons' bump into electrons to produce 'voltage'/power. the process is naturally called the 'photo-voltaic effect'. the loose electrons are captured by an electrical conductor in the solar cell (usually made of silicon) and a circuit is completed ... solar panels may generate more power than is actually needed. this extra power is simply stored in lead-acid batteries (they store upto 000 watts). read more about it here...

Q:what is a solar panel?
A panel that is attached to the top of a roof of a house that converts the suns rays into electrical energy that can be harnessed and used to power appliances, light rooms etc. through silicon particles.
