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.

2.Main Features of the Solar Module

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

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.

13. When sliding snow load has to be considered, an appropriate measure has to be taken so that PV module frames on lower edge of PV modules will not be damaged.

14. Do not expose PV module to sunlight concentrated with mirrors, lenses or similar means.

15. Turn off inverters and circuit breakers immediately, should a problem occur.

16. In case the glass surface of a PV module is broken, wear goggles and tape the glass to keep the broken pieces in place.

17. A defective PV module may generate power ever if it is removed from the system. It may be dangerous to handle the PV module while exposed to sunlight. Place a defective PV module in a carton so PV cells are completely shaded.

18. In case of series connection , the maximum open circuit voltage must not be greater than the specified maximum system voltage. The voltage is proportional to the number of series. In case of parallel connection, please be sure to take proper measure to block the reverse current flow. The current may easily flow in a reverse direction.

Q: If one buys tons of solar panels and sells electricity(possible in my country) can he earn money ?: This year my friend put in $54,000 worth of solar panels on his roof (7KW). He got a $2,000 rebate from the state. So his cost is $42,000. Now this summer, in the heat of the day, when he runs his air conditioner, he is still selling a trickle of power to the company. Other times he sells a lot. At night or on cloudy days, he buys power from the company. His payback period is going to be about 25 years. But this will be 0-5 years after he dies, probably.

Q: How do solar panels affect the property's energy consumption?: Solar panels can significantly reduce a property's energy consumption by harnessing sunlight to generate electricity. By converting sunlight into clean, renewable energy, solar panels can offset much of the electricity that would otherwise be drawn from the grid. This leads to lower energy bills and a decreased reliance on fossil fuels, ultimately resulting in a more sustainable and eco-friendly energy consumption for the property.

Q: Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!: Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.

Q: Can solar panels be used to power a zoo?: Yes, solar panels can be used to power a zoo. Solar panels can generate electricity by converting sunlight into energy. This renewable energy source can effectively power various operations within a zoo, including lighting, heating, cooling, and powering animal enclosures, as well as other facilities such as gift shops and food stands. By utilizing solar panels, zoos can reduce their dependency on fossil fuels, lower their carbon footprint, and contribute to a more sustainable and environmentally friendly operation.

Q: Can solar panels be installed on historical buildings?: Yes, solar panels can be installed on historical buildings. However, the installation process may require special considerations to maintain the historical integrity of the structure.

Q: Properties of solar panel?I know this is too general,but i am to write a report on the materials used to make solar panels,and i am to include the physical, mechanical ,and chemical properties of the materials.It's just too general,such that i am lost.There are so many types of solar panels.So i hope some experts on this subject can give me a general guide lines ,maybe the tensile strength ?as much as you can please.: Properties Of Solar Energy

Q: What is the most affordable, yet highest watt solar panels available?: Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.

Q: Pros and Cons if I get solar panels?: If solar panels were cost effective we would all be buying them and you would see them on the roof of every home. They are not. It is cheaper to buy electricity from the electric utility company.

Q: Why is it nessicary, with today's economy in the postion it's currently in, to use renewable energy sources; like 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: Do solar panels increase property value?: Yes, solar panels have been found to increase property value. Studies have shown that homes with solar panels tend to sell at a higher price and faster than those without. Additionally, the potential for reduced energy bills and the positive environmental impact of solar energy can make a property more attractive to potential buyers, thus increasing its overall value.
