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.

 1).High conversion efficiencies resulting in superior power output performance.

 2).Outstanding power output even in low light or high temperature conditions

 3).Optimized design for ease of soldering and lamination

 4).Long-term stability,reliability and performance

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.

4、INSTALLATION SAFETY

1.    Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).

2.    Keep the PV module packed in the carton until installation.

3.    Do not touch the PV module unnecessarily during installation. The glass surface and the frames get hot. There is a risk of burn, or you may collapse because of electric shock.

4.    Do not work under rain, snow or windy conditions.

5.    Use insulated tools

6.    Do not use wet tools

7.    Do not drop tools or hard objects on PV modules

8.    When installing PV modules far above ground, do not drop any object(e.g. PV module or tools).

9.    Make sure flammable gases are not generated near the installation site.

10.  Completely cover the PV module surface with an opaque material during PV module installation and wiring.

11.  Plug in the connector tight and ensure the wiring work.

12.  Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.

13.  Do not touch the terminal box and the end of output cable ends ( connectors) with bare hands during installation or under sunlight, regardless of whether the PV module is connected to or disconnected from the system.

14.  Do not unplug the connector if the system circuit is connected to a load.

15.  Do not stamp on the glass at work. There is a risk of injury or electric shock if glass is broken.

16.  Do not work alone (always work as a team of 2 or more people).

17.  Wear a safety belt if working far above the ground.

18.  Do not wear metallic jewelry which can cause electric shock during installation.

19.  Do not damage the surrounding PV modules or mounting structure when replacing a PV module.

20.  Bind cables by the insulation locks. Drooping down of cables from the terminal  box could possibly cause various problems such as animal biting electricity leakage in puddle.

Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
Q:The future of solar panels?
I think the solar panel will be better as the development of technology. A solar panel company called OKorder once did a research of the future of solar panels and gave many datas to prove the bright future of it. Find it on Internet.
Q:Nuclear reactors vs. Solar panels?
You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
Q:Solar Panel Manufacturing?
At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
Q:can a small solar panel be charged with lamps?
That would depend on the frequency that the solar panel accepts and the frequency of light that your lamp gives out. It may or may not work. The sun gives out a much broader spectrum of light, which is why solar panels are much more effective in sunlight. I have seen solar panels charged by lamps, but it usually doesn't work that well and I have never seen it work with fluorescent lighting.
Q:how efficient are flexible solar panels?
I don't have a number, but in general, no one uses a flexible panel unless they are compelled to. The efficiency is lower, and my experience is that they don't last. I had one a few years ago, and it lasted less than 2 years. My rigid panels came with a 25-year performance warranty, and are still working great after 7 years.
Q:What direction do solar panels usually point?
South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
Q:Opinions on Solar Panels?
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
Q:Why should I use solar panels?
How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles 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 many volts does an average solar panel produce?
2 volt and 24 volt are both common sizes. They are rated in voltage and watts. So you add the watts of the panels and buy enough to produce the amount of watts you need. For example, if you need 400 watts of power at 2 volts, you would buy four 00 watt 2 volt panels and connect them in parallel.
