1.Structure of Solar Module Description

Solar panel refers either to a solar hot water panel, a common type of a solar thermal collector, or to one or more solar photovoltaics (PV) modules, electrically connected and mounted on a supporting structure.

A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic systemthat generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.



Specification of  Solar Polycrystalline

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.

GENERAL SAFETY

1.    Consult local codes and other applicable laws concerning required permits on regulations concerning installation and inspection requirements.

2.    Before installation a PV module, contact appropriate authorities to determine permit, installation and inspection requirements that should be followed.

3.    Install PV modules and ground frames in accordance with applicable rules and regulations

4.    PV modules should be installed and maintained by qualified personnel. Only installer/service personnel should have access to the PV module installation site.

5.    No matter where the PV modules are installed, either roof mounted construction or any other type of structures above the ground, appropriate safety practices should be followed and required safety equipment should be used in order to avoid possible safety hazards. Note that the installation of some PV modules on roofs may require the addition of fireproofing, depending on local building / fire codes.

6.    Please use PV modules with same cell size within series.

7.    Follow all safety precautions of other components used in the system.

8.    In order to avoid a risk of injury or electrical shock, do not allow anyone to approach the PV module if the person has little knowledge on PV module or on the measures that should be taken when PV modules are damaged.

9.   Do not clean the glass surface with chemicals. Do not let water stay on the glass surface of PV modules for a long time. This creates a risk of white efflorescence(glass disease) which may result in the deterioration of energy generation.

10. Do not clean the glass surface with chemicals. Do not let water stay on the glass surface of PV modules for a long time. This creates a risk of white efflorescence ( glass disease ) which may result in the deterioration of energy generation.

11.  Do not install the PV module horizontally. It may cause dirt or white efflorescence (glass disease) due to water.

12.  Do not cover the water drain holes of the frame. There is a risk of frost damage when the frame is filled with water copulation.

Q:Tell me the guidelines for making solar panels?
If you're expecting to use them for anything other than a science fair project, don't bother. In order to produce any significant amount of power, solar panels have to be made of complex materials and coated with special coatings. If you want to power anything with them you'll need an inverter. Solar is not a DIY project (no matter how much those scam kits claim). If you're serious about solar, call your local solar installer and talk to them about it.
Q:How many solar panels do I need?
A typical home in America can use either electricity or gas to provide heat -- heat for the house, the hot water, the clothes dryer and the stove/oven. If you were to power a house with solar electricity, you would certainly use gas appliances because solar electricity is so expensive. This means that what you would be powering with solar electricity are things like the refrigerator, the lights, the compute­r, the TV, stereo equipment, motors in things like furnace fans and the washer, etc. Let's say that all of those things average out to 600 watts on average. Over the course of 24 hours, you need 600 watts * 24 hours = 4,400 watt-hours per day. From our calculations and assumptions abo­ve, we know that a solar panel can generate 70 milliwatts per square inch * 5 hours = 350 milliwatt hours per day. Therefore you need about 4,000 square inches of solar panel for the house. That's a solar panel that measures about 285 square feet (about 26 square meters). That would cost around $6,000 right now. Then, because the sun only shines part of the time, you would need to purchase a battery bank, an inverter, etc., and that often doubles the cost of the installation. If you want to have a small room air conditioner in your bedroom, double everything.

Q:solar panels on projectors?
Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.
Q:Do solar panels shine/have luster? Please help me. Easy ten points!?
The problem with solar panels is that they often come with textured glass. This makes that the reflected light is scattered +/-0°. Therefore the 0.5° sun-disk small as it aprears in the sky will be blown up 40 times to a 20° reflection disk on solar panels. Find more information on zehndorfer.at/en/glaringsurvey Only a glaring survey can tell you exactly when and where you have to expect a dazzling effect.
Q:Maintenance of Solar Panel?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:How to build a solar panel?
Building solar panels is not really a do it yourself kind of job. They are made in high tech factorys with specialized equipment and experianced engineers. It would probably be cheaper and easier to just buy some panels rather than try to make your own.
Q:How much can I expect it to cost to install solar panels?
Power inverter to change 2VDC panel power to 220VAC House power. (~$600) You are also going to need various switches and a meter to keep track of how much you are sending back to your power company. Final answer... Expect to pay ~$7,000.00 with installation by a qualified electritan.
Q:Electricity question about solar panels?
Watts = Volts * Amps Your heater needs at least 500 watts of AC power. The solar panel only produces about 200 watts of power ( 24volts * 8amps). Not enough to run the heater. Also, the solar panel produces DC current, not the AC current that the heater needs. However, if you had solar panel that produced enough power (watts), you could buy a transformer to turn the panel's DC output into the required AC output. But that doesn't seem like a real cost-effective plan.
